AI Technical Summary

Technical Problem

Existing vehicle communication antennas are large in size, take up a lot of space, are unstable to install, and have a fixed installation position, making them difficult to disassemble and inspect, affecting driving safety.

Method used

The communication antenna adopts an assembled structure, including a shell, a base, a ceramic substrate and a connector. A stable accommodating cavity is formed by snapping and pressing. The ceramic antenna is installed on the vehicle's rearview mirror, using the high dielectric constant and low loss characteristics of the ceramic material to improve the gain, and signal transmission is achieved through a FAKRA connector.

Benefits of technology

The communication antenna is miniaturized and stably installed, which is convenient for disassembly, assembly and inspection, improves communication capabilities and ensures driving safety.

Abstract

The present invention relates to a communication antenna and a vehicle equipped with the communication antenna. The communication antenna comprises a housing with an opening, a base, a ceramic substrate, and a connector. The base is snap-fitted to the opening and forms a housing cavity between the housing and the base. A mounting member is connected to the base for mounting the communication antenna on the vehicle. The ceramic base is positioned within the housing cavity. The ceramic base comprises a ceramic antenna and a base body, the ceramic antenna being mounted on the base body, the surface of the base body forming the antenna's radiating surface. One end of the connector passes through the base and is electrically connected to the ceramic antenna. This invention achieves a smaller size and improved integration. The communication antenna utilizes an assembled structure with extremely strong structural stability, allowing it to be mounted on a vehicle's rearview mirror.
