Vehicle 4g ​​Active Integrated Gain Antenna

Abstract

The invention discloses a vehicle-mounted 4G active integrated gain antenna, which includes three parts: a PCB antenna module, an active gain amplification module, and a terminal radio frequency input RF IN module. The vehicle-mounted 4G active integrated gain antenna involved in the present invention combines a PCB antenna module and an active gain amplifier module to form an integrated structure, which not only increases the gain, improves the transmission and reception signal strength of 4G communication network signals, but also facilitates installation; solves the problem of vehicle-mounted In case of unstable reception of 4G communication network signals, it can enhance the reception and transmission of 4G communication network signals in the vehicle environment, which has application prospects.

Description

technical field [0001] The invention relates to a booster antenna for a 4G vehicle-mounted terminal, in particular to an integrated structure of a vehicle-mounted 4G terminal antenna and an active amplifier. Background technique [0002] Many IOV terminals in the prior art are equipped with 3G or 4G communication networks, but because the 3G or 4G communication in the prior art uses cellular networks based on mobile base stations, there must be areas with poor coverage. This phenomenon is especially obvious when the vehicle is traveling at high speed. The network signal strength will continue to change, resulting in network signal instability, which will affect the communication of the Internet of Vehicles terminal, and cannot realize real-time transmission of voice, SMS, and data. [0003] In order to enhance the network signal, the prior art adopts an antenna, but the antenna of the prior art adopts a simple PCB antenna, and the strength of receiving and sending network si...

Problems solved by technology

[0002] Many existing IoV terminals have 3G or 4G communication networks, but since the existing 3G or 4G communications use cellular networks based on mobile base stations, there must be areas with poor coverage

This phenomenon is especially obvious when the vehicle is traveling at high speed. The network signal strength will continue to change, resulting in network signal instability, which will affect the communication of the Internet of Vehicles terminal, and cannot realize real-time transmission of voice, SMS, and data.

[0003] In order to enhance the network signal, the prior art adopts an antenna, but the antenna of the prior art adopts a simple PCB antenna, the strength of receiving and sending network signals is not ideal, and cannot meet the needs of users
