Abstract

The invention relates to an omnidirectional antenna of a communication system, in particular to a multi-band broadband dual-polarization LTE omnidirectional antenna. The multi-band broadband dual-polarization LTE omnidirectional antenna comprises a passive splitter filter, a horizontal polarization low-frequency oscillator unit, a horizontal polarization high-frequency oscillator unit, wherein the horizontal polarization low-frequency oscillator unit at least comprises three sheets, and the horizontal polarization low-frequency oscillator unit, the horizontal polarization high-frequency unit are connected with the passive splitter filter via a unit feeding coaxial cable. Depending on the combiner characteristic and the filtering characteristic of the passive splitter filter, the signals of the horizontal polarization low-frequency oscillator unit and the horizontal polarization high-frequency unit are integrated via the directional diagram overlapping synthesis technology of multi-frequency combined combiners, the function of a horizontal polarization full-band unit is achieved, and full-band coverage of horizontal polarization is achieved. The antenna has high data throughput capacity, can satisfy the frequency coverage demand of the fourth generation of mobile communication standard 4G LTE, and realize multi-input and multi-output data receiving and transmitting.

Description

technical field [0001] The invention relates to an omnidirectional antenna for a communication system, in particular to a multi-band broadband dual-polarization LTE omnidirectional antenna. Background technique [0002] In recent years, due to the rapid development of informatization, mobile terminals have become more and more popular online. According to statistics, there are about 600 million users nationwide using mobile terminals to browse the Internet, and China has become the country with the largest number of mobile terminal Internet users in the world. [0003] Due to the rapid growth of mobile terminal Internet users in China, the network data transmission volume has increased sharply, and the network carrying capacity of operators has been overwhelmed. Among them, the vast majority of mobile terminal users access the network indoors. The data throughput capability of the indoor distribution system is a key issue, but it is obviously not enough for the current sing...
