Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

With the rapid development of the fifth generation mobile communication system (5G), the antenna of the modern mobile communication terminal needs to support the original 4G frequency band (700-960 mhz and 1710-2690 mhz) and the newly added 5G sub6G frequency band (3200-5000 mhz) at the same time. The existing printed mobile communication antenna technology has limitations when covering three frequency bands of 700-960 MHz, 1710-2690 MHz and 3200-5000 MHz, and the existing printed mobile communication antenna technology also cannot reach an ideal state in the aspect of radiation efficiency.

As shown in fig. 1, in the antenna structure in the related art, although the bandwidth of the antenna is widened by designing multiple branches to cover the original 4G LTE band (700-960 mhz and 1710-2690 mhz), the bandwidth is not successfully extended to the 5G sub6G band (3200-5000 mhz). This suggests that current antenna designs have limitations in frequency coverage that cannot meet the higher requirements of 5G communications for antenna bandwidth.

In addition, the antenna exhibits poor radiation efficiency at the edge frequency. Insufficient standing-wave ratio depth means that the antenna is poor in impedance matching under certain frequencies, so that the reflectivity of the signal is high, the energy radiated outwards is reduced, and the radiation efficiency of the antenna is reduced. This is a significant drawback for 5G technology, where high efficiency communication is sought.

Although a certain bandwidth widening can be achieved by the multi-branch structure, the bandwidth performance of the antenna in the prior art needs to be improved. Bandwidth is an indicator of the range of antenna frequency response, and for modern communications antennas that need to support multiple frequency bands simultaneously, a wider bandwidth means better frequency coverage capability, and stable performance at different frequencies. The bandwidth performance of the antenna in the prior art is limited, and the coverage requirement of an ultra-wideband frequency band is difficult to meet.

In summary, the mobile communication antenna in the prior art has shortcomings in terms of frequency coverage and radiation efficiency, especially, the coverage of 3200 to 5000mhz frequency band for 5G communication requirement, and the maintenance of high radiation efficiency in high frequency band are the main technical challenges faced by the prior art. These problems limit the use of antennas in 5G communication systems, highlighting the urgent need to develop a new type of antenna that can cover ultra wideband frequencies and maintain high efficiency.

In order to solve the technical problem of narrow bandwidth of an antenna in the related art, according to one aspect of the embodiment of the present invention, as shown in fig. 2, the antenna is printed on a dielectric substrate 1, and the antenna comprises the dielectric substrate 1, a radiating element 2, a feed port 4, a parasitic element 3, and a grounding port 5 and a parasitic element 6, wherein the radiating element 2, the parasitic element 3 and the parasitic element 6 are disposed on the dielectric substrate 1, the radiating element 2 is connected with the feed port 4, the radiating element 2 is used for radiating a radiation signal in a first frequency band, the parasitic element 3 is grounded through the grounding port 5, one end of the parasitic element 6 is connected with the parasitic element 3, the other end of the parasitic element 6 is grounded, the parasitic element 3 is used for radiating a radiation signal in a second frequency band together with the radiating element 2, and a first gap 7 exists between the radiating element 2 and the parasitic element 3.

The antenna provided by the invention is printed on a dielectric substrate 1, a grounded side is arranged on the dielectric substrate 1, the basic structure of the antenna can comprise a radiation unit 2, a parasitic unit 3, a feed port 4 for accessing radiation signals to the radiation unit 2, a grounding port 5 for connecting the parasitic unit 3 and the ground, and a lumped device 6 for adjusting the overall impedance of the antenna.

The feed port 4 is a starting point of a signal current entering the antenna, and the antenna can receive the signal current from the outside, i.e., radiate a signal, through the feed port 4. The radiating element 2 is the most predominant radiator in an antenna, and it may be designed by various structures to increase the path length of the current of the signal inside the radiator, thereby exciting a plurality of resonant modes. These modes cover different frequency ranges, enabling the antenna to operate in a wider frequency band. The current in the radiating element 2 can be coupled into the parasitic element 3 through the first slot 7, and the parasitic element 3 can excite resonance of other frequency bands, so that the bandwidth of the antenna is further widened. The ground port 5 is a path for signal current to flow back to the ground, ensuring good grounding of the antenna, and thus optimizing the performance of the antenna. The current flows back to the grounding point through the parasitic radiation branch, a closed current path is formed, and the current is very important for improving the radiation efficiency of the antenna. In addition, a part of clearance area is also present on the dielectric substrate 1, namely, the part around the antenna is not printed with any circuit or metal, which provides necessary isolation for the antenna, avoids interference with other circuits or antennas, and further improves the performance of the antenna. Wherein the radiating element 2 may radiate a radiation signal in a first frequency band, and the parasitic element 3 may widen the width of the radiation frequency band of the antenna as a whole by interaction with the radiating element 2, i.e. the parasitic element 3 may jointly implement radiation of the radiation signal in a second frequency band with the radiating element 2. The first frequency band and the second frequency band may include original 4G frequency bands (700-960 MHz and 1710-2690 MHz) and newly added 5G sub6G frequency bands (3200-5000 MHz).

The lumped devices 6 refer to elements in the circuit having independent electrical properties, such as inductances, capacitances, etc., which can be placed independently in the circuit for achieving a specific function. In an antenna, loading lumped inductance or capacitance can change the impedance characteristics of the antenna, so that the impedance matching of the antenna at different frequencies is more optimized. For example, loading the lumped inductor can increase the inductance of the antenna and reduce the Q value (quality factor) of the antenna, so that the antenna maintains good impedance matching in a wider frequency range, and the operating bandwidth of the antenna is further widened.

The radiation efficiency of the antenna is related to the impedance of the antenna, the matching state of the antenna, the loss of the antenna, and the like. By loading the lumped device 6, the impedance of the antenna can be adjusted, the impedance matching of the antenna can be optimized, the loss of the antenna can be reduced, and the radiation efficiency of the antenna can be improved. In the invention, the loading of the lumped inductance device not only widens the bandwidth, but also improves the radiation efficiency of the antenna by reducing the loss and optimizing the matching state.

Through the design, the antenna disclosed by the invention realizes ultra-wideband frequency coverage (700-960 MHz, 1710-2690 MHz, 3200-5000 MHz) and high radiation efficiency, has the size of 60mm by 20mm, can be suitable for various electronic products, and is low in cost. In addition, the suitability of the antenna is very strong, the antenna can be used on PCB mainboards with different sizes, high flexibility and practicability are shown, the technical problem of narrow antenna bandwidth in the related art is solved, and an ideal antenna structure design is provided for the 5G communication terminal.

As an alternative embodiment, the parasitic element 3 comprises an L-shaped radiating stub.

Alternatively, the parasitic element 3 may affect the resonance characteristics of the antenna by interacting with the radiating element, thereby widening the bandwidth of the antenna or exciting additional resonance points to cover more frequency ranges. The L-shaped structure can effectively increase the path length of current flowing in a smaller area, which means that signal current can flow back to the grounding point only by a longer distance on the parasitic unit 3.

As an alternative embodiment, grooves are provided on the L-shaped radiating branches to increase the flow path of the current over the L-shaped radiating branches.

Alternatively, providing grooves on the L-shaped radiating branches may increase the length over which current flows on the L-shaped radiating branches, i.e. the path of the current in the grooves becomes longer. This increased current flow length over the L-shaped radiating branches helps excite additional resonance points, especially at higher frequency bands, which can widen the bandwidth of the antenna to cover more frequency ranges. In addition, in the circuit, the grooves can be equivalent to unevenly distributed capacitors or inductors, which can affect the impedance of the antenna, and the antenna can be helped to maintain good impedance matching in a wider frequency range, so that the bandwidth and the efficiency of the antenna are improved.

In addition, the position and size of the notch can control the resonant mode of the antenna. By arranging the grooves at proper positions on the L-shaped radiation branches, the distribution of current can be influenced, so that the antenna generates an expected resonance mode under a specific frequency, and the effective coverage of a required frequency band is realized. It should be noted that, as shown in fig. 2, the grooves are disposed on longer branches of the L-shaped radiation branches, and in addition, the positions of the grooves, the depth and the shape of the grooves may be adjusted according to actual needs.

As an alternative embodiment, a first sub-slit 11 and a second sub-slit 12 are present at different positions between the radiating element 2 and the L-shaped radiating branch, respectively, wherein the first slit 7 comprises the first sub-slit 11 and the second sub-slit 12.

Optionally, a first slot 7 is present between the radiating element 2 and the parasitic element 3, and after the radiating signal enters the radiating element 2 through the feed port 4, the radiating signal may be coupled to the parasitic element 3 through the first slot 7, and the signal in the parasitic element 3 may also affect the signal in the radiating element 2 through the first slot 7. In summary, the radiating element 2 and the parasitic element 3 may interact through the first slit 7. In case the parasitic element 3 is an L-shaped radiating stub, the parasitic element 3 and the radiating element 2 may be coupled through a first sub-slit 11 and a second sub-slit 12. As shown in fig. 2, the first sub-slit 11 may implement coupling of one side of the bent "L" shape with the radiating element 2, and the second sub-slit 12 may implement coupling of the other side of the bent "L" shape with the radiating element 2. The parasitic element 3 and the radiating element 2 are coupled through the two sections of sub-slots, so that the radiation efficiency of the antenna can be improved, and the overall performance of the antenna is improved.

As an alternative embodiment, a second gap 8 is present between a first edge in the parasitic element 3 and the grounded edge on the dielectric substrate 1, wherein the first edge is the edge provided with the ground port 5.

Alternatively, the slot may be equivalent to a capacitance in the circuit, which introduces an equivalent capacitance between the parasitic element 3 and ground when the slot is arranged between the first edge and the grounded edge on the dielectric substrate 1. The capacitor can change the impedance characteristic of the antenna, so that the antenna can realize impedance matching in a wider frequency range, and the bandwidth of the antenna is further widened. As shown in fig. 2, the first edge may be an edge of the parasitic element 3 where the ground port 5 is provided. In the actual design process, the overall structure and the impedance of the antenna can be considered, and the position of the gap and the width of the gap can be adjusted to achieve a better effect.

As an alternative embodiment, a third gap 9 is present between a second edge in the radiating element 2 and the grounded edge on the dielectric substrate 1, wherein the second edge is the edge provided with the feed port 4.

Alternatively, a third gap 9 may also be provided between the second edge, which may be the edge of the radiating element 2 where the feed port 4 is provided, and the grounded edge on the dielectric substrate 1.

As an alternative embodiment, an L-shaped slot 10 is provided in the radiating element 2 to increase the flow path of the current over the radiating element 2.

Optionally, in the antenna provided by the invention, the radiation unit 2 may be further provided with an L-shaped slot 10, so as to increase the flow path of the current on the radiation unit 2, thereby widening the working bandwidth of the antenna and optimizing the radiation efficiency thereof. Specifically, the L-shaped slot 10 increases the flow path of the current on the radiating element 2, which means that the actual electrical length of the signal current on the antenna becomes long. The increase in electrical length helps excite additional resonance points, especially at high frequency bands, which can allow the antenna to maintain stable performance over a wider frequency range, thus achieving ultra-wideband coverage.

As an alternative embodiment the lumped device 6 is an inductance or a capacitance. Optionally, an inductor or a capacitor is additionally arranged on the antenna, so that the overall impedance of the antenna can be adjusted in a relatively visual and controllable manner. Particularly, when the lumped device 6 is an inductor, the inductance value can be increased, and the Q value (quality factor) of the antenna can be reduced, thereby widening the operating bandwidth of the antenna. In addition, the use of lumped devices helps to improve the radiation efficiency of the antenna. For example, adding lumped inductance can reduce the loss in the high frequency band, while loading lumped capacitance can improve the impedance matching of the antenna, thereby reducing reflection losses, allowing more energy to be radiated efficiently.

The use of lumped devices allows for a miniaturized design of the antenna. By regulating and controlling the parameters of the lumped devices, the electrical characteristics of the antenna can be changed without increasing the physical size of the antenna, and the strict limitation of modern communication equipment on the internal space is met.

As an alternative embodiment, the radiating element 2 comprises an irregularly edged radiator.

Alternatively, setting the edges of the antenna radiator to be irregularly shaped, instead of a conventional rectangular shape, can optimize the performance of the antenna, in particular, widen the bandwidth and improve the radiation efficiency. The irregular edges may include meanders, serrations or wedges, etc. that provide a more complex current path than the rectangular edges, helping the antenna to cover a wider frequency range.

The performance of an antenna is limited by its structure and size. The design of the irregular edge allows the resonant characteristics of the antenna to be controlled and adjusted to create resonance points at multiple frequencies. Through the shape of the fine design edge, the response of the antenna in different frequency bands such as 700-960MHz, 1710-2690 MHz, 3200-5000 MHz and the like can be optimized, and multi-band coverage is realized. The radiation pattern of the antenna is also affected by its structure. The irregular edge design can change the radiation characteristics of the antenna, for example, by a specific edge shape, the radiation directivity and the pattern of the antenna can be improved, unnecessary side radiation is reduced, and the efficiency of the antenna in the main radiation direction is improved. In addition, in the multi-antenna system, the design of the irregular edges is beneficial to reducing the coupling effect between the antennas, so that the performance of the antenna array is improved, and the overall performance and stability of the system are enhanced.

The antenna provided by the invention covers the frequency bands of 700-960 MHz, 1710-2690 MHz, 3200-5000 MHz and the like, simultaneously maintains high radiation efficiency and miniaturization characteristics, and effectively realizes high performance of the antenna in multi-band application by providing more complex current paths and optimized impedance characteristics.

As a specific example, as shown in fig. 2, the antenna may be printed on the FR-4 dielectric substrate 1, and one side of the dielectric substrate 1 is grounded so that the antenna can be grounded. The antenna comprises a radiating element 2, which radiates mainly, and a parasitic element 3, which radiates secondarily, a signal can be input to the radiating element 2 through a feed port 4, then coupled to the parasitic element 3 through a first slot 7, and finally reflowed through a ground port 5. In order to widen the bandwidth of the antenna, a lumped device 6 is further provided in the antenna, and the lumped device is connected to one side of the parasitic element 3 and the grounded dielectric substrate 1, and then grounded. The inductance value can be increased through the lumped device 6, the Q value is reduced, the bandwidth of the antenna is widened, and the radiation efficiency of the antenna is optimized.

In order to further improve the performance of the antenna, a second slot 8 and a third slot 9 are further arranged on the antenna, the impedance of the antenna is adjusted through loading an equivalent capacitor by the slots, so that wider bandwidth is obtained, an L-shaped slot 10 is further arranged in the radiating unit 2, a current flow path is increased, a high-frequency current flow path of the antenna is increased, broadband design is realized, the shapes of radiation branches included in the parasitic unit 3 can be further arranged in a folding, multi-branch, slot and other modes, so that the signal has current paths with different lengths, resonance modes with different frequencies are excited, a plurality of resonance frequencies are created, and the purpose of covering the whole 5G frequency band is achieved.

It should be noted that fig. 2 only provides an alternative antenna structure, and on this basis, the positions where the grooves are disposed, the sizes of the grooves, the disposed positions of the lumped devices 6, the specific parameters of the lumped devices 6, the disposed positions of the slots, the sizes of the slots, etc. may be flexibly adjusted according to actual needs.
