Abstract

The invention relates to a vehicle-mounted multimode antenna, and the antenna comprises a PCB, a satellite antenna which is disposed on the PCB and is used for receiving a GPS signal, an LTE main antenna and an LTE diversity antenna, wherein the LTE main antenna and the LTE diversity antenna are disposed on the PCB. The LTE main antenna and the LTE diversity antenna are disposed at corners of thePCB, and the feed layout of the LTE main antenna and the LTE diversity antenna is of a diagonal type. The LTE main antenna and the LTE diversity antenna are set in a manner of an extending branch node. The antenna achieves the more high-frequency modes through coupling, improves the isolation degree, is very high in overall efficiency, is simple in structure, and is easy to manufacture.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a vehicle-mounted multi-mode antenna. Background technique [0002] With the advent of the Internet of Vehicles era, the application of vehicle antennas is becoming more and more diversified to meet people's increasingly high information transmission, entertainment, positioning and navigation. At present, there are various designs of vehicle antennas. Multiple antennas are integrated into one carrier, and miniaturization and multi-mode are the trend of vehicle antennas. The LTE communication antenna system generally consists of two parts: a main antenna and a diversity antenna. The main advantage of adding diversity antennas is to reduce the correlation of received signals, so that the channels of signals in space have a low correlation with each other, resulting in the effect that channels will not be faded at the same time; at the same time, it can improve 4G communication t...
