[0001] The utility model relates to the field of automobile parts, in particular to a vehicle-mounted antenna and a car. Background Art
[0002] Most existing vehicle-mounted antennas are shark fin antennas. The shark fin antenna module includes a 4G antenna, a GNSS ceramic antenna, a PCB board, a base, and a wiring harness. The 4G antenna, GNSS ceramic antenna, and wiring harness are connected to the PCB board by welding. The PCB board is connected to the base by screws, and the base is connected to the roof of the car. Since the height of the 4G antenna is the highest in the antenna module, the height of the 4G antenna determines the height of the antenna module.
[0003] The signals received by the 4G antenna and GNSS ceramic antenna are amplified by the circuit on the PCB board, and then transmitted to the T-BOX by the wiring harness for subsequent signal processing. Since the shark fin antenna module is located on the roof and is far away from the T-BOX, the required wiring harness is longer, which increases the cost of the entire vehicle. Utility Model Content

The utility model provides a vehicle-mounted antenna, the base of which can be used as a 4G low-frequency antenna, reducing the overall height of the vehicle-mounted antenna, with a lower profile and better performance.

[0053] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0054] refer to Figure 1 , an embodiment of the present application provides a vehicle-mounted antenna 1, comprising: a base 2, a PCB board 3, two 4G high-frequency antennas 4 and a GNSS ceramic antenna 5. Among them, the base 2 is a sheet structure made of metal material, which serves as a 4G low-frequency antenna. Exemplarily, the base 2 (4G low-frequency antenna) is a 4G LTE antenna, which can cover the 698-960MHz frequency band; Exemplarily, the 4G high-frequency antenna 4 is a 4G LTE antenna, which can cover the 1710-2690MHz frequency band. The base 2 (4G low-frequency antenna) and the 4G high-frequency antenna 4 are used to receive signals required for telephone, Internet access and mobile communications. The GNSS ceramic antenna 5 is a square structure, which is arranged on the upper surface 33 of the PCB board 3, between the first end 31 and the second end 32. The GNSS ceramic antenna 5 can cover the 1559MHz-1606MHz frequency band and is used to receive signals required for global positioning navigation.
[0055] Continue to refer Figure 1 The PCB board 3 is in a square shape and is disposed on the upper surface of the base 2. The PCB board 3 includes a first end 31 and a second end 32. Figure 1 In the X direction), a 4G high frequency antenna 4 is respectively provided at the first end 31 and the second end 32, and the two 4G high frequency antennas 4 are symmetrically arranged, and the distance between the two 4G high frequency antennas 4 is as far as possible.
[0056] Continue to refer Figure 1 The 4G high frequency antenna 4 is composed of a first part 41 and three first connecting parts 42, wherein the first part 41 is in a strip shape, and the surface of the first part 41 is provided with four rectangular hollow parts 411 arranged at intervals, along the third direction ( Figure 1 The first portion 41 is spaced apart from the PCB board 3, and three first connecting portions 42 are connected to the PCB board 3. Two first connecting portions 42 are in the shape of long strips, and one first connecting portion 42 is in the shape of an arc.
[0057] With the above technical solution, the signal tower transmits a signal, but since the signal is weak, the base 2 as a 4G low-frequency antenna, the 4G high-frequency antenna 4 and the GNSS ceramic antenna 5 receive the weak signal, and the signal is amplified through the circuit of the PCB board 3. Compared with the prior art, the 4G antenna in the prior art is a whole, consisting of a 4G low-frequency antenna part and a 4G high-frequency antenna part. Therefore, in this technical solution, the base 2 is used as a 4G low-frequency antenna part, and the corresponding height of the 4G low-frequency antenna in the prior art is cancelled, which can reduce the overall height of the vehicle-mounted antenna 1, making the profile lower and obtaining better performance. At the same time, the base 2 is a sheet structure made of metal material, which can ensure that the base 2 is used as a 4G low-frequency antenna part. The distance between the two 4G high-frequency antennas 4 is as far as possible, which can improve the isolation between the two 4G high-frequency antennas 4. The GNSS ceramic antenna 5 is located between the two 4G high-frequency antennas 4 to prevent signal interference between the two 4G high-frequency antennas 4 and further improve the isolation between the 4G high-frequency antennas 4.
[0058] like Figure 1 As shown, the 4G high frequency antenna 4 extends upward from the feed point (the connection between the first connection part 42 and the PCB board 3) for a distance d and then bends horizontally to form a planar first part 41. Four square hollow parts 411 are etched on the first part 41. The multiple branches formed by the four square hollow parts 411 increase the path for the current to flow. The first connection part 42 is vertically inserted into the PCB board 3, and the base 2 is connected to the PCB board 3. The base 2 serves as the 4G low frequency antenna part, thereby forming a 4G low frequency current path. The current path a is as shown in FIG. Figure 1 As shown by the dotted arrow in , it includes horizontal polarization and vertical polarization.

[0063] With the above technical solution, the base 2 (4G low-frequency antenna), 4G high-frequency antenna 4 and GNSS ceramic antenna 5 receive weak signals, and the signal is amplified through the circuit of the PCB board 3. The amplified signal is transmitted to the T-BOX through the wiring harness 6 for subsequent signal processing. The wiring harness of the traditional shark fin antenna needs to be connected to the T-BOX from the roof through the A-pillar, which requires more body wiring harnesses. However, this technical solution only needs to use the wiring harness 6 of the vehicle-mounted antenna 1 itself to connect to the T-BOX, and it can keep a close distance with the T-BOX, greatly reducing the cost of the body wiring harness.
