Multi-frequency broadband combined antenna applied to vehicle-mounted environment

Abstract

A multi-frequency broadband combined antenna applied to a vehicle-mounted environment disclosed by the present invention comprises a circular reflection floor, four 5G/4G antenna units and six WIFI antenna units, the four 5G/4G antenna units are placed around the circular reflection floor, and the six WIFI antenna units are dispersedly placed in the middle of the circular reflection floor according to a certain layout. The four 5G/4G antenna units meet the requirements of traditional 2G/3G/LTE/5G frequency bands, the six WIFI antenna units meet the requirements of 2.4/5.8 GHz WiFi and Bluetooth frequency bands, the multi-frequency broadband performance is achieved, and the three isolation plates are placed in the middle of the circular reflection floor, so that the isolation performance between the antenna units is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication systems, in particular to a multi-frequency broadband combined antenna applied in a vehicle-mounted environment. Background technique [0002] In recent years, the development of the 4G communication era has also encountered bottlenecks while achieving great achievements. In the aspect of in-vehicle communication, the initial requirements for the Internet of Vehicles can be realized, such as Bluetooth connection, real-time road conditions, etc., but in the face of the communication requirements in the 5G era, Especially for the Internet of Vehicles requirements such as autonomous driving that require higher transmission rates and lower latency, the performance of 4G communication is difficult to meet the requirements. But at the same time, due to various objective reasons, the layout of 5G base stations has not been fully completed in China, and 4G communication still occupi...

Problems solved by technology

[0003] Most MIMO (Multiple-Input Multiple-Output) car antennas on the market can only cover 2G / 3G / LTE frequency bands, and the bandwidth of the antenna unit is generally narrow, and the overall antenna size is too large, making it difficult to adapt to the complex in-car environment

Shark fin car antenna is favored by the market due to its relatively beautiful appearance, but the relatively fixed structure makes it limited in the number of antennas it can accommodate, and it is difficult to be compatible with the 5G frequency band and cope with the increasingly complex in-car communication environment, which makes the compact car box Antennas have more application scenarios
