Background

With the rapid development of the wireless communication field, the vehicle-mounted electronic equipment develops towards networking and intellectualization, and a large number of devices need to be connected to a wireless network for communication. Due to the existing situation of coexistence of networks with multimode and multiband, such as 2G, 3G, 4G and the like, the vehicle-mounted communication equipment needs to support a full-standard working mode, and the number of vehicle-mounted receiving antennas and the number of supported frequency bands are greatly increased.

The vehicle-mounted antenna is used as an important medium for communication between personnel in the vehicle and the outside, and the performance of the vehicle-mounted antenna directly influences the communication quality. Generally, the higher the antenna profile, the more excellent the parameters such as the gain of the antenna; however, in order to reduce air resistance, the appearance of the automobile is generally streamlined, which limits parameters such as the section of the vehicle-mounted antenna, and further limits the performance such as the gain of the vehicle-mounted antenna. In order to balance the gain and size of the antenna, shark fin antennas are widely used in recent years, the smooth appearance of the shark fin antennas can reduce wind resistance brought by the protruding antennas to a certain extent, and the high antenna profile of the shark fin antennas is beneficial to accommodating the high-gain antennas.

However, most current shark fin antennas are adhered and fixed on the top of an automobile, once the shark fin antennas are fixed, subsequent disassembly is troublesome, damage to the painted surface of the automobile can be caused after disassembly, and once the shark fin antennas are not aligned during adhesion, the shark fin antennas can be inclined to affect an outer pipe.
