The present invention relates to an antenna and an antenna module for receiving a satellite signal, and more particularly, to receive a satellite signal in a Global Positing System (GPS), Digital Multimedia Broadcasting (DMB), Digital Audio Broadcasting (DAB), and navigation. It relates to a non-square patch antenna, and an integrated antenna module including the same.

In recent years, the use of wireless communication is rapidly increasing, and in order to meet the popularization of wireless communication devices, a slim antenna that can be mounted inside a transceiver according to the trend of focusing on design and cost reduction and mass production while maintaining the performance of the antenna Demand is rising.

In general, a microstrip patch antenna is used in a vehicle receiver for using mobile multimedia information, a broadcasting service, or a current location and an electronic map service. The reason is that in order to minimize the influence of the ionosphere interference and the multipath signal (noise) reflected from the ground, the satellite transmits a right hand circular polarization and receives the GPS satellite signal. Circular polarization antenna is used because patch antenna is cheap and good reception rate among various kinds of circular polarization antenna. The patch antenna is a kind of antenna that is light in weight and has a flat structure that takes up little space but can have the largest gain and directivity in a given space. It is used as a communication relay antenna of various mobile communication devices and portable devices. .

1 is an exploded view showing the structure of a patch antenna according to the prior art, which is shown in the top and bottom surfaces.

As shown in FIG. 1, the conventional patch pin type square patch antenna includes an antenna module 12 and a printed circuit board (PCB) 14 separated therefrom. The antenna module 12 is coated with a conductive material on both end surfaces of the dielectric block 11, the feeding pin 13 is located on the top surface. In addition, one or more low noise amplifiers 15 are formed in the PCB 14, and the PCB 14 is attached to the bottom surface of the antenna module 12. The conductive surface of the top surface is coated with a conductive material in the same ratio of width and length to implement circular polarization characteristics. In addition, the feeding pin 13 is electrically connected to the conductive surface of the top surface to penetrate through the dielectric block, but is formed to be electrically separated from the ground surface made of the conductive material of the bottom surface.

However, the problem of the patch antenna used in the conventional navigation and the like is that a 'ground plane', for example, basically a flat conductive surface is required, and in order to facilitate the reception of satellite signals, the PCB must have a ground plane with a sky cross section. Is that. In addition, the size of the smallest patch antenna currently used is 18 × 18mm, it is difficult to mount in the user equipment due to the limitation of the width of the receiver and the antenna height problem. Thus, as can be seen in Figure 2 showing a navigation with a square patch antenna as described above, the antenna mechanism 18, which can be unfolded and folded from the body, is located behind the top of the navigation 17, and within Since there is no choice but to configure the patch antenna to be positioned, there is a problem that the antenna mechanism protrudes laterally as much as the width of the antenna when used.

In recent years, as the trend toward slimmer and smaller portable devices has been combined with the functions of products, for example, a car navigation company needs to develop a navigation device that can be mounted on a vehicle and is portable with a built-in battery. However, as described above, the conventional patch antenna does not become slim and increases the size of navigation and the like, and even when mounted in a vehicle using a small patch antenna of 13 × 13 mm or less, the antenna characteristics are not good, so reception in a shaded area is not possible. There is also the problem of instability. In addition, the square patch antenna has a characteristic of selectively receiving left hand circular polarization and right hand circular polarization when receiving a satellite signal with a circular polarization antenna. You need to redesign based on whether it is polarized or port polarized. In the case of designing a dual band antenna, the reception rate may be reduced due to the mutual interference effect according to the design of the left polarized wave receiving antenna and the star polarized wave receiving antenna.

On the other hand, according to the miniaturization trend, there have been attempts to use a smaller patch antenna or linear polarization antenna of 13 × 13 mm or less, but the smaller the antenna, the lower the performance and reception sensitivity of the antenna, for example, a signal of -130 dbm is used. In the case of existing GPS engines, signal processing is not possible. Therefore, in the current market, there is a demand for the development of an antenna or an antenna module that can be built to satisfy the miniaturization and portability while maintaining or exceeding a conventional antenna.

The present invention has been made to solve the structural problems and design problems of the receiver such as the navigation according to the use of the conventional square patch antenna described above, the patch antenna positioned on the non-square dielectric block and the non-square dielectric block By adjusting the conduction pattern of the non-square patch antenna of the dielectric block having circular polarization characteristics or improved linearly polarizing characteristics, and extending the conductive pattern of the upper surface to the side of the non-square dielectric block has circular polarization characteristics or Provides a non-square patch antenna of a dielectric block having a linear polarization characteristics, and implements a conductive pattern formed with one or more grooves in the upper end of the dielectric block to facilitate mounting of a patch antenna having a circular polarization characteristics inside the user equipment Providing antenna module And a purpose.

In addition, by implementing the integrated antenna module to attach the patch antenna and the low noise amplifier to a single PCB, and the integrated antenna module to attach the patch antenna and the GPS engine module to a single PCB, the reception performance of the antenna is as good as the conventional antenna The object of the present invention is to develop an antenna or an antenna module that can be maintained or more and can be built to satisfy miniaturization and portability.

The size of the conductive pattern is characterized in that it is controlled.
Here, in the non-square patch antenna for receiving the satellite signal, the conductive pattern may be formed with at least one groove in which the conductive pattern is removed from both sides of the shorter side at the upper end of the dielectric block, the conductive pattern Has circular polarization characteristics.

The conductive pattern has circular polarization characteristics.

Figure 3a is a view showing the top, side and bottom surfaces of the first embodiment of the non-square patch antenna for receiving satellite signals according to the present invention, respectively.

As shown, the patch antenna according to the first embodiment of the present invention is a feeding pin type patch antenna, which is composed of a dielectric block 21 and a conductive pattern 22. Here, the dielectric block (hereinafter, also referred to as 'dielectric block') 21 is formed in a non-square, and the conductive pattern 22 is horizontally and horizontally corresponding to the shape of the dielectric block 21 at the upper end of the dielectric block 21.

Although the drawing 32 is electrically insulated from the ground surface of the bottom surface, the inside of the hole 34 is filled with silver (Ag) differently from the manner in which the feeding pin 23 of the first embodiment protrudes from the bottom of the dielectric block. As a result, the input / output terminal 33 and the conductive surface 32 of the upper end of the dielectric block are electrically connected to each other and penetrate through the dielectric block 31 and open to the ground surface 35 made of a conductive material at the lower end thereof. The shape of the dielectric block 31 and the conductive pattern 32 at the upper end is the same as that of FIG. 3A.

The patch antenna may implement various types of patch antennas using various materials. However, the patch antenna according to the present invention uses a dielectric having a high dielectric constant of 6 to 60, thereby degrading performance (gain x bandwidth and volume). However, since it can be small and have a low profile, it contributes to the miniaturization of a communication device and has an advantage that the risk of damage to the external impact on the device is small due to the built-in type. In addition, the antenna according to the present invention can exhibit sufficient performance in the frequency range of several hundred MHz to several GHz used by most systems such as wireless communication or cellular phone, and its use area will be widened in the future.

Square patch antenna according to the prior art, when developed as a patch antenna having the characteristics of starboard polarization, there is a problem that can receive only satellite signals of starboard polarization due to the reception characteristics and satellite signals sent to the left side polarization cannot be received. . On the other hand, since the non-square patch antenna according to the present invention has the characteristics of linear polarization, it can receive a wide range of signals regardless of the polarization direction of the satellite signal, as well as improved signal processing characteristics such as SIRstar 3 GPS engine can be used to supplement the reception performance. In addition, due to the characteristics of the linearly polarized light of the non-square patch antenna according to the present invention, as in the case of the conventional square patch antenna, it is possible to solve the problem that the reception rate is lowered due to the mutual interference caused by the circular polarization, the design of dual band Is easy.

Figure 4a is a view showing the top, side and bottom surfaces of a fourth embodiment of the non-square patch antenna of the dielectric block according to the present invention.

The patch antenna according to the present invention is a non-square patch antenna of a feeding pin type, and is composed of a dielectric block 51 and a conductive pattern 52. Here, the dielectric block 51 is formed in a non-square, the ratio of the width and length of the conductive pattern 52 applied to the upper end of the dielectric block 51 is different, the conductive pattern 52 to both sides of the longer side The feeding pin 53 is positioned in the conductive surface 52 of the upper end of the patch antenna, and is electrically connected to the conductive surface of the upper end of the patch antenna, penetrating the upper and lower end surfaces of the dielectric block 51, and the conductive material of the lower end. It is electrically separated from the ground surface 54 which was formed. By forming a conductive pattern on the side of the dielectric block, it is possible to implement the circular polarization characteristics electrically, and by adjusting the ratio of the horizontal and vertical length of the conductive pattern extending to the side can exhibit a linear polarization characteristic improved electrical properties.

The patch antenna according to the present invention is an SMT type non-square patch antenna, in which the conductive pattern 62 is extended to both sides of the long side of the dielectric block 61 in the same manner as the patch antenna of the fourth embodiment. Structure. Instead of the feeding pin 53 of the fourth embodiment, the input / output terminal 63 and the inside of the hole 64 are coated with silver (Ag) to electrically connect the input / output terminal 63 and the conductive surface 62 of the upper end, and It is a patch antenna that allows the SMT to be applied by implementing the conductive pattern 64 made of silver to open through the dielectric block to the ground surface 65 made of the conductive material at the lower end thereof.

4C is a diagram illustrating a sixth embodiment of a non-square patch antenna for receiving satellite signals according to the present invention.

The patch antenna according to the present invention is another non-square patch antenna of the SMT type, and the conductive pattern 72 is extended to both sides of the long side of the dielectric block 71 in the same manner as the patch antenna of the fourth embodiment. It is an extended structure. The conductive surface 72 of the top surface of the dielectric block 71 of the patch antenna is electrically separated from the ground surface 73 made of a conductive material at the bottom, and is electrically separated from the ground conductive surface 73 at the bottom. SMT is applied to form a conductive input and output terminal 74, and to form a conductive pattern 75 on either side of the opposite side of the conductive pattern 72 is extended to match the input and output terminals.

The non-square patch antennas of the dielectric blocks according to the fourth to sixth embodiments of the present invention form circular polarization characteristics by forming conductive patterns on the sides of the dielectric blocks and the dielectric blocks having different widths and lengths, or conductive patterns. The non-square patch antenna of the dielectric block, which improves the characteristics of the linearly polarized wave according to the size adjustment, is also a miniaturized antenna than the conventional square patch antenna, which can be mounted inside the user equipment and improves the reception performance. In addition, unlike the square patch antenna, it is possible to design a dual band. Particularly, when the circular polarization characteristic is used, the reception characteristics of the conventional patch antenna can be reduced while maintaining the reception characteristics of the conventional patch antenna, thereby enabling the transmission and reception of two or more channels at one frequency and taking advantage of the circular polarization with low polarization loss. .

5 shows a seventh embodiment of a non-square patch antenna of a dielectric block according to the present invention.

The patch antenna according to the present invention implements a conductive pattern 78 having a groove formed by removing one or more conductive patterns on both sides of the shorter side of the dielectric block 76 having different ratios of width and length, and feeding pins. 77 is located in the conductive surface 78 of the upper end of the patch antenna, and electrically connected to the conductive surface of the upper end of the patch antenna, penetrating the upper and lower surfaces of the dielectric block 76, and the ground conducting surface 79 of the lower end. ) Is electrically isolated. The patch antenna has two antenna characteristics of a linearly polarized wave type, each of which is separated by high frequency and low frequency at 13 mm on one side. As the grooves are added while removing the shorter side of the conductive pattern, the width of the conductive pattern narrows to less than 13 mm, shifting the characteristics of other linearly polarized antennas in the 1.8 Ghz band to approximate another low frequency linearly polarized characteristic. As a result, each linearly polarized antenna characteristic has a circular polarization characteristic with a frequency, magnitude, and phase angle of 90 degrees. Particularly, in the case of circular polarization characteristics, the polarization can be miniaturized while maintaining the reception characteristics of the conventional patch antenna, and polarization is realized by implementing a conductive pattern on a long-term dielectric dielectric block having high quality (Q * f: quality characteristics of materials). Not only can it take advantage of the circularly polarized wave with a small loss, but also has better characteristics against noise than a square antenna.

The patch antenna in which the groove is formed in the conductive pattern is not limited to the above-described specific embodiments, and is applied to all of the second to sixth embodiments according to the present invention, thereby providing various types of non-square patches of the feeding pin type or the SMT type. Circular polarization characteristics can be realized with an antenna. In particular, non-square patch antennas, such as 13 × 18mm or 13 × 20mm, can realize circular polarization characteristics by extending the conductive pattern to the side of the dielectric block, but the length of one side is considerably longer like a 13 × 25mm patch antenna. In this case, it is preferable to implement circular polarization characteristics by forming a groove in the conductive pattern of the upper end while extending the conductive pattern on the side.

Since the patch antenna according to the first to sixth embodiments implements a linear shape having a length of 13 mm and a width of 18 to 35 mm or 35 mm or more due to the width of the user equipment such as navigation, the user equipment Can be mounted inside. In addition, while reducing the size of one side, it is possible to improve Q * F by using a high dielectric constant of Er 60 or less. For example, a 13 × 18 mm patch antenna can use ceramic powder with a relative dielectric constant (Er) of 45 with a Q * F of 40,000 or more, while a 13 × 20 mm patch antenna has a dielectric constant of 35,000 with a Q * F of 35,000 ( By using ceramic powder of Er) 37, the loss caused by the raw material can be reduced, the antenna gain can be improved, and the reception characteristics are better than that of the conventional square patch antenna.

Hereinafter, embodiments of the integrated antenna module including the non-square patch antenna of the dielectric block according to the present invention will be described in detail with reference to FIGS. 6 to 14C.

It is configured to be done. Signals up to the second amplification are sent to the GPS engine via a connected cable. The low noise amplifier has a problem of narrowing bandwidth due to miniaturization according to a high dielectric constant of an antenna that can be used in the antenna module, thereby amplifying the received satellite signal to be processed by a GPS engine. There is also a method of attaching the patch antenna directly to the GPS engine, but in this case, since the satellite signal is too weak to be vulnerable to noise, the GPS may be amplified by gain of at least 24 dB through amplification and filtering by a low noise amplifier as described above. It is desirable to have a signal input to the engine.

Thus, according to the configuration in which the patch antenna 81 and the low noise amplifier 82 are attached to different surfaces of the PCB 83, the effect of noise on the non-square patch antenna from the low noise amplifier generated in the signal transmission process can be minimized. It also has advantages.

In the integrated antenna module according to the present embodiment, two blocks of the PCB 83 end to which the patch antenna 81 of the dielectric block is attached and the PCB end 84 to which the low noise amplifier 82 is attached are coaxial cables. Connected to 85. In this case, both PCB stages may have a rectangular shape, but the present invention is not limited thereto. The PCB may be replaced with a flexible PCB. According to the antenna module of this configuration, the PCB stage 84 to which the low noise amplifier 82 is attached has an advantage of free 360 ° rotation. That is, when spatial constraints and bending in the receiver are required according to the use of the coaxial cable, not only an antenna module may be implemented as shown in FIGS. 10A to 10C, but the present invention is not limited thereto and may be implemented in various forms according to a designer's intention. This is possible.

11 is a view showing a fourth embodiment of the integrated antenna module according to the present invention.

The integrated antenna module according to the present embodiment includes a non-square patch antenna 81 of a dielectric block according to the present invention, and a miniaturized GPS engine that performs data associating with a satellite signal received by the patch antenna to output data.

It is attached by-. According to the present invention, the GPS smart antenna module has a width of 65 × 10 × 7mm and only a portion where the patch antenna 81 is positioned to have a width of 13 mm or less so that the width thereof is narrow rather than longer than the square patch antenna. Losing character. On the other hand, by replacing the DAB or DMB antenna and the GPS engine using the above method with a DAB engine or DMB engine, the integrated GPS antenna engine module can be used for DAB or DMB as well as navigation or GPS.

In the integrated antenna module according to the present embodiment, the non-square patch antenna 81 and the GPS engine module 91 of the dielectric block according to the present invention are provided with SMD (Surface Mount Devices) method on different surfaces of the PCB 92. Each is attached. Thus, according to the configuration in which the patch antenna 81 and the GPS engine module 91 are attached to different surfaces of the PCB 92, the effect of noise on the patch antenna in the low noise amplifier of the GPS engine module generated in the signal transmission process is affected. It also has advantages that can be minimized.

13 is a view showing a sixth embodiment of an integrated antenna module according to the present invention.

Two blocks of the PCB 93 having the non-square patch antenna 81 attached to the dielectric block according to the present embodiment and the PCB 94 having the GPS engine module 91 attached thereto are connected by a coaxial cable 95. . In this case, both PCB stages may have a rectangular shape, but the present invention is not limited thereto. The PCB may be replaced with a flexible PCB. According to the antenna module of such a configuration, the PCB stage 94 to which the GPS engine module 91 is attached has an advantage of free 360 ° rotation. That is, when spatial constraints and bending in the receiver are required according to the use of the coaxial cable, not only the antenna module may be implemented as shown in FIGS. 14A to 14C, but the present invention is not limited thereto. It is possible.

In this case, the GPS engine module may be implemented as an integrated unit of a low noise amplifier and a miniaturized GPS engine, a GPS engine itself without a low noise amplifier, or a band pass filter and a GPS engine. Therefore, those skilled in the art can design the GPS engine module as needed, and in general, it is desirable to integrate a miniaturized GPS engine, a band pass filter, and a low noise amplifier of one stage.

In the above described and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims. For example, the amplifier is not limited to the integrated antenna module or the integrated GPS antenna engine module according to the present invention, but the ground noise is shielded from the low noise amplifier stage or the GPS engine module with a conductive material to prevent noise and oscillation of the antenna. In this case, the noise effect on the antenna can be reduced.

The non-square patch antenna of the dielectric block and the integrated antenna module using the same according to the present invention can be mounted inside the user equipment as a miniaturized antenna or antenna module than the commercially available square patch antenna and has an effect of improving reception performance.

That is, if the non-square patch antenna according to the present invention having the characteristics of linear polarization is used, the reception performance can be compensated for by improving signal processing of an engine such as SIRstar 3, but weak in a multipath signal (noise). The same antenna can be used regardless of star polarization, and the antenna module can be mounted inside the terminal by miniaturizing the size of the antenna module compared to the conventional square patch antenna.

In addition, by forming a conductive pattern on the side of the dielectric block of the non-square patch antenna according to the present invention that is different from the horizontal and vertical, it has a circular polarization characteristic or a non-square dielectric block using a high dielectric constant of 30 or more and the length of the short axis When extending more than 12mm by forming a conductive pattern on the top of the dielectric block can have a circular polarization characteristics.
In addition, for a dielectric block designed to be installed on an inner side of a wireless communication device, when the width of the dielectric block is less than a predetermined value (for example, 13 mm), the conductive pattern is designed to have linear polarization characteristics, and the width thereof is If more than (eg, 13mm ~ 15mm or more), it is possible to maximize the performance of the satellite signal receiving antenna by designing a conductive pattern to have a circular polarization characteristic.
In addition, the non-square patch antenna of the dielectric block, which improves the characteristics of the linear polarization according to the adjustment of the size of the conductive pattern, is also a miniaturized antenna than the conventional square patch antenna, can be mounted inside the user equipment and has an improvement in reception performance. .

In addition, if one or more grooves are formed in the conductive pattern of the dielectric top surface of the non-square patch antenna, the width of the conductive pattern is narrowed, so that the characteristics of other linearly polarized antennas in the 1.8 GHz band gradually move to the low frequency and the other low frequency It is close to the linearly polarized antenna of, and its frequency, magnitude, and phase angle are 90 °, which shows circular polarization characteristics.

In particular, when the non-square patch antenna has a circular polarization characteristic, the reception characteristics of the conventional square patch antenna can be reduced while maintaining the advantages of circular polarization with low polarization loss. As manufacturing becomes easier, the disadvantages can be solved while taking advantage of the conventional square patch antenna.

Next, an integrated antenna module for implementing the non-square patch antenna on a low noise amplifier and a single PCB, and an integrated GPS antenna engine module for implementing the non-square patch antenna on a single PCB may also be a conventional square patch antenna. While maintaining the reception performance of the present invention, it is possible to solve the design problem of the conventional terminal by positioning the inside of the user equipment according to the miniaturization.

Furthermore, the integrated antenna module or the integrated GPS antenna engine module may not only be positioned parallel to the horizontal direction at the upper end of the user equipment, but may be slightly bent or inclined depending on the terminal design, thereby enabling various applications.
