The present invention relates to an integrated antenna module for transmitting / receiving an automobile, and in particular, by installing an integrated antenna having a plurality of antennas having different characteristics in one case on a roof surface of a vehicle to perform a role as an antenna, The present invention relates to an integrated antenna module for transmitting / receiving a vehicle which can minimize the number and size of the antennas and at the same time improve the direction and characteristics of the antenna.

Traditionally, an AM / FM radio broadcast receiving antenna is a pole type rod antenna having excellent reception efficiency and is installed and used outside the vehicle. Although the load antenna has good reception efficiency, the glass antenna is often used due to the problem of poor safety and aesthetics.

Meanwhile, as DMB (Digital Multimedia Broadcasting) services are recently available, DMB receiving antennas have been developed and spread. DMB is classified into terrestrial DMB (T-DMB) and satellite DMB (S-DMB) according to the signal transmission method. In basic operation, terrestrial DMB (T-DMB) is a system that transmits a signal from a broadcasting center to a tower and transmits the signal from each tower to a terminal, and satellite DMB (S-DMB) is a high-frequency satellite. It is a system that spreads broadcasting signal in frequency band. Such a DMB system can be received through a portable terminal such as a mobile phone or a transmission receiver, and can provide a variety of contents such as graphics, video, and data as well as high-quality voice, thereby realizing a broadcasting service converged with communication.

Thus, in addition to the antenna for receiving radio broadcasting, there is a need for a terrestrial DMB receiving antenna, a satellite DMB receiving antenna, and the like, in accordance with a consumer's desire. For example, Utility Model Registrations 378172 and 392631 disclose satellite DMB reception antennas. However, in the related art, since the above-described functional antennas are independently supplied and installed, there is a problem that is very weak in economical efficiency or mounting performance. In addition, since the size and shape of the antenna is different depending on the frequency, the appearance is not good, and there is a disadvantage in that the manufacturing cost is also high because the antenna is manufactured for each characteristic.

This required the development of an integrated antenna. For example, Korean Patent Publication No. 2005-47832 discloses an integrated antenna for automobiles. The disclosed integrated antenna is arranged on the same plane as the air wave receiver, the GPS receiver, and the PCS receiver inside the case having a center portion projecting downward and a wing portion extending left and right from the center portion. However, this integrated antenna can not only receive a lot of air resistance in appearance, but also various antennas are simply arranged in a coplanar manner and simply assembled regardless of the reception efficiency.

In addition, Korean Utility Model Registration No. 20-0406832 discloses an integrated antenna for receiving a radio / ground-DMB. The disclosed radio / ground-DM reception integrated antenna is equipped with an antenna for receiving radio broadcasting and an antenna for receiving terrestrial DMB, and is formed of a streamlined body and a wing to minimize the resistance of air in appearance. However, since the integrated antenna for receiving radio / ground DMB can only receive radio broadcast and terrestrial DMB broadcast, there is a disadvantage in that a separate receiving antenna must be installed when receiving a signal such as CDMA or GPS. In addition, the integrated antenna for receiving radio / ground DMB is provided with an antenna for receiving radio broadcast and an antenna for receiving terrestrial DMB, respectively.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to include a plurality of antennas having different characteristics (for example, AM / FM, terrestrial DMB, CDMA, GPS antenna, etc.) in one case.

Here, the plurality of circuit boards are preferably installed separated by a predetermined interval on the mounting table under the integrated antenna case.

The helical antenna 110 is provided with AM, FM, terrestrial DMB antenna functions. The operation principle is that the performance of two or more antennas can be realized with one antenna by separately using the received signal using a band pass filter provided therein.

The integrated antenna module for transmitting / receiving of a vehicle is provided with a plurality of antennas having different characteristics inside the case, and minimizes signal interference with each other to maintain unique antenna characteristics. The principle of operation is as follows.

In general, the helical antenna uses two frequencies in the antenna itself, and uses them separately from the antenna and the input matching part of the circuit part. Isolation is obtained by using a filter at the input side (for example, -30dBm: 1/1000). Segregation ensures minimum mutual interference in radio waves and means that the two systems are separated from each other. GPS, CDMA, etc. are separated from the VHF antenna by installing a separate antenna. In addition, interference due to different frequency ranges from each other can be minimized. If the antenna has a separation of -30dBm, it can be regarded as separate antennas.

In the case of maintaining the characteristics of the antenna, by securing isolation and installing each separate antenna, the electrical characteristics of the antenna itself do not change. However, in the case of the interference part between each other (because of the small overall size), the performance of the antenna can be satisfied by securing the mounting fixed position and the separation distance from each other for the characteristics of the antenna. For example, satellites should only look at the sky, but if there is another metal material directly above the antenna, it may be somewhat interfered. Therefore, in order to compensate for this, the position of the antenna may be moved and mounted to the side that does not interfere.

Therefore, even if a plurality of antennas having different characteristics are provided inside the integrated antenna case 10, signal interference between the antennas can be reduced to a minimum, thereby maintaining the unique characteristics of the antennas.

In addition, the integrated antenna module for transmitting and receiving the vehicle may change the characteristics of the helical antenna 110 according to the material of the integrated antenna case 10. At this time, the material of the integrated antenna case 10 is preferably one of ASA, ABS, PC + PBT. Here, the principle of changing the characteristics of the helical antenna 110 according to the material of the integrated antenna case 10 is as follows.

In general, in the case of the antenna, the dielectric constant (εr) is the most important of the properties of the material.

The material of the integrated antenna case 10 should use a material in consideration of the transmittance, conductivity, etc. of the radio wave when the antenna receives the radio wave, and if a metal material is used, the radio wave is not transmitted, so a material having a maximum transmittance should be used. do. Therefore, the material of the integrated antenna case 10 is made of ASA, ABS, PC + PBT, etc., because the antenna has good radio wave transmittance, low cost, and no deformation when mounting the vehicle.

The length of the wavelength of the radio wave varies according to the dielectric constant of the integrated antenna case 10 material, and in the case of air, the dielectric constant of the material is determined based on 1.0006. In the case of the dielectric constant currently in use, the dielectric constant is about 1.52 to 2.1, and the electrical characteristics of the antenna change accordingly. For example, if the dielectric constant is high, the antenna's natural frequency range shifts to the following frequency when the antenna measured in air is used as it is. This phenomenon is caused by the change of the wavelength inherent in the material part during radio wave transmission. Conversely, if the dielectric constant is less than air, the natural frequency characteristic of the antenna moves to a higher frequency. A typical antenna using this principle is a PCB patch antenna. In the case of a PCB, the antenna has a high dielectric constant of up to 10, which can be used to make the antenna longer at low frequencies.

Therefore, since the characteristics of the helical antenna 110 can be changed according to the material of the integrated antenna case 10, it is possible to make the length of the antenna longer at a lower frequency to be somewhat smaller.

In the integrated antenna module for transmitting / receiving the vehicle, the VHF band signal reception method is mounted by raising the helical antenna 110 to about 25 degrees to 45 degrees and mounting the signal received from the helical antenna 110 to the first to the first. After passing through only the desired frequency bands through the three filter units 210 to 212, the signals are sent to the first to third amplifiers 310 to 312 to amplify the signals, respectively, and then the AM / FM radio receivers 410 and 420 of the vehicle. And terrestrial DMB receiver 440. In the case of a vehicle GPS, the GPS antenna 130 receives the signal transmitted from the satellite and the GPS is transmitted through the fourth amplifier 313, the fourth filter 213, and the fifth amplifier 314. Sent to receiver 440. In addition, in the case of CDMA, the mobile phone and the passive antenna which receives the signal through the CDMA antenna 120 and is sent to the CDMA receiver 430 are installed to receive the signal to be used in the vehicle.

Separate signals received from the roof antennas of the vehicle are separated from the signals inside the separately mounted amplifiers and sent to the receivers installed in the vehicle, and each antenna is configured to minimize the mutual separation and interference of the antennas. .

In the case of the roof antenna of the vehicle, the VHF band antenna minimizes the total and size of the antenna by simultaneously implementing and applying the radio and terrestrial DMB in the vehicle, and it is excellent in terms of space utilization by minimizing the range in which the separate antenna is mounted. By utilizing the space, by installing the satellite antenna and the CDMA antenna 120 together, it is possible to install several antennas in the shape of a single module antenna, and the shape of the antenna can be changed in consideration of the space and design of the vehicle. For the purpose of separation, the shape of the antenna may be changed in consideration of the arrangement and characteristics of the antenna and the conditions of the vehicle.

As shown in Figure 1, the integrated antenna module for transmitting and receiving of the vehicle is preferably installed on the roof surface of the vehicle to be used in combination and integrated various antennas used in the vehicle. As such, when the integrated antenna module is installed on the roof surface of the vehicle, the maximum performance efficiency can be seen in the vehicle, and the characteristics of the antenna, such as reception efficiency and directionality, are superior to reception using the heating wire of the vehicle. In addition, the roof surface of the vehicle cancels the noise generated in the vehicle, thereby increasing the overall efficiency.

A radio wave received from a roof antenna of a vehicle is applied to a receiver through an amplifier, and each amplifier is provided with a magnetic band filter according to the intended use and an impedance converter for coupling characteristics with the antenna. Minimize mutual interference with the ground plane of the roof antenna to improve mutual separation and safety.

The radio part of the vehicle is configured to receive AM / FM together from the roof antenna of the vehicle as one output terminal by using the helical antenna 110, and to separate and amplify and combine each other in the amplifier. There is no need to install a separate antenna by using the electric coupling type in the radio antenna like the terrestrial DMB antenna, and it is necessary to install the antenna redundantly by separating the radio and terrestrial DMB signals from the input part of the circuit. There is no. In terms of space, it is excellent in terms of space utilization by using VHF antennas together, it is excellent in assembly and mounting conditions in vehicles, and it is possible to provide a dynamic curve in terms of design of the device, thereby making it possible to make the structure of the desired structure. This prevents duplicate investments in the production of equipment.

In the antenna using the roof of the vehicle, the antenna uses the vertical and horizontal planes of the antenna cover, and the height can be minimized by giving the angle of the antenna using the vertical and horizontal planes, and is suitable for the appearance and maintenance of the vehicle. There is little change of characteristics according to environment.

In the antenna using the roof of the vehicle, it is possible to form a plurality of antennas, it is also advantageous to the shape of the output contact point, the output connector can be formed in the tool mold supporting the antenna, and also in consideration of the characteristics of the antenna Angles improve antenna space and assembly workability.

The CDMA antenna 120 is made of an inexpensive AF4 PCB and designed to fit the CDMA frequency by reducing the size of the CDMA antenna, so that only the matching is possible without a special circuit, thereby reducing the price and size.

In general, for a CDMA antenna, the system is a passive antenna type. In this case, a separate circuit other than the antenna is not necessary. This is because the antenna is characterized throughout the use band, so no separate circuit is required. In the case of FR4, it is a PCB, and the band being used is high (1.8GHz), and the antenna can be miniaturized in the band, and it is a passive antenna by using the antenna for both transmitting and receiving.

The GPS antenna 130 uses a basic patch antenna. However, in order to detect a small signal from the satellite, the signal is first amplified at the antenna input terminal, and then a signal of a predetermined band (for example, 1.57542 GHz) is detected from the amplified signal and the signal is amplified again and transmitted to the communication equipment. Done.

When each of these antennas are put together in one apparatus, the interference between the antennas occurs. In particular, radio, terrestrial DMB antennas, CDMA antennas, and GPS antennas are the most important factors affecting each other, and this is the most important factor determined by the direction, angle, and position of the antenna.

In addition, a noise prevention pad (for example, a sound absorbing pad) may be installed on at least one of the portions where the helical antenna is provided along the inner surface of the integrated antenna case. In this case, the sound absorbing pad reduces sound energy by absorbing sound waves when the sound waves pass through the medium or touch the surface of the object, thereby reducing the progress or noise of the vehicle.
