[0027] Please see Figures 1 to 2 This utility model discloses a five-in-one vehicle antenna, which includes:

[0028] Base plate 1;

[0029] A cover 2 is connected to the base plate 1, and a receiving space is formed between the cover 2 and the base plate 1. The receiving space contains two non-contact LTE antennas 3, two WIFI antennas 4, and one GPS antenna 5.

[0030] The LTE antenna 3, WIFI antenna 4 and GPS antenna 5 are all vertically mounted on the base plate 1. The two LTE antennas 3 and the two WIFI antennas 4 are located at the ends of the base plate 1, and the GPS antenna 5 is located at the center of the base plate 1.

[0031] In the above configuration, the housing 2 is connected to the base plate 1, forming an accommodating space between them to house the two LTE antennas 3, two WIFI antennas 4, and one GPS antenna 5. All five antennas are vertically mounted on the base plate 1. The two LTE antennas 3 and the two WIFI antennas 4 are located at the ends of the base plate 1, while the GPS antenna 5 is located at the center of the base plate 1, and they do not contact each other. This achieves a high degree of integration, combining two LTE antennas 3, two WIFI antennas 4, and one GPS antenna 5 into a single unit. This integration incorporates multiple key technologies to meet the needs of modern intelligent vehicles, optimizing both electrical performance and cost-effectiveness.

[0032] Please see Figure 1 Specifically, in this embodiment, the base plate 1 is made of aluminum so that the two LTE antennas 3, two WIFI antennas 4 and one GPS antenna 5 can be integrated on it to integrate multiple key technologies to meet the needs of modern intelligent vehicles.

[0033] Specifically, in this embodiment, both LTE antennas 3 adopt a PCB structure, which integrates the antenna and the circuit board together, saving space and making it easier for the LTE antennas 3 to be integrated on the base plate 1.

[0034] Specifically, in this embodiment, a copper sheet 6 is welded to the top of each LTE antenna 3 to extend the antenna bandwidth.

[0035] Specifically, in this embodiment, both WIFI antennas 4 adopt a PIFA structure, so that each WIFI antenna 4 can work simultaneously in the 2.4G / 5.8G frequency bands.

[0036] Specifically, in this embodiment, the GPS antenna 5 includes an L1 frequency band and an L5 frequency band, both of which use ceramic dielectric. More specifically, the L1 and L5 frequency bands of the GPS antenna 5 are surrounded by a metal isolation mesh.

[0037] Please see Figure 1 and Figure 2 Specifically, in this embodiment, the cover 2 is a shark fin-shaped structure. The advantage is that it makes the five-in-one vehicle antenna more perfectly integrated with the vehicle body shape. At the same time, the structure also combines aerodynamic and aesthetic principles, effectively reducing airflow noise and making driving quieter. The antenna is installed in the accommodating space formed by the cover 2 and the base plate 1, which can effectively prevent the antenna from being stolen and has a higher security factor.

[0038] Please see Figure 1Specifically, in this embodiment, the base plate 1 and the cover 2 are connected by bolts 7. For example, self-tapping bolts 7 can be used to connect the two along the periphery of the base plate 1 and the cover 2 at appropriate intervals.

[0039] Please see Figure 1 and Figure 2 Specifically, in this embodiment, the base plate 1 is provided with a fastening assembly on the side facing away from the cover 2, so that the five-in-one vehicle antenna can be connected to the external mounting position. The fastening assembly includes an open bolt 87 on the side of the base plate 1 facing away from the cover 2 and a nut 9 adapted to the open bolt 87. When connecting the five-in-one vehicle antenna to the external mounting position, a serrated washer 10 can also be used to cooperate with the open bolt 87 and the nut 9 to achieve the function of locking and preventing loosening.
