Problems solved by technology

However, the traditional dual-polarized antenna has only one feed port and cannot directly use a differential circuit, but needs to use a balun or other conversion device to be able to use a differential circuit to connect to a communication system
This practice will add additional power loss and complicate the structure

Abstract

The present invention provides a wide beam scanning dual-frequency dual-polarization micro base station antenna applied to 5G communication. The antenna comprises includes a first dielectric plate, asecond dielectric plate, a third dielectric plate and a feed structure in order from the top to bottom. Radiation patches are affixed to the first dielectric plate and the second dielectric plate, thefeed structure is arranged on the third dielectric plate, the first dielectric plate and the second dielectric plate are coupledly fed through the feed structure of the third dielectric plate, at thesame time, a reflective floor is under the third dielectric plate, an air layer is arranged between the first dielectric plate and the second dielectric plate, and the second dielectric plate is in direct contact with the third dielectric plate. According to the antenna of the invention, the wideband characteristic of the antenna is achieved, the bandwidth of the two ports of the antenna covers the bands of 3.3-3.69 GHz and 4.75-5 GHz respectively, the antenna can be applied to the 5G communication, the high isolation and low cross polarization performance are achieved, and a 1*4 high gain antenna array is achieved through a differential feed network.

Description

[technical field] [0001] The invention belongs to the technical field of communication, and in particular relates to a wide-beam scanning dual-frequency dual-polarization micro base station antenna and an array thereof applied to 5G communication. [Background technique] [0002] With the rapid development of modern mobile communication technology, the communication system has higher and higher requirements for antennas. [0003] In the modern mobile communication system, a new type of antenna has been widely concerned by many experts, scholars and engineers. It is the dual-polarized antenna. The dual-polarized antenna can simultaneously form a pair of working modes with orthogonal polarization modes and the same frequency. Thus, frequency reuse can be realized. At the same time, because the antenna can receive all the polarization information of electromagnetic waves in the sky, it has strong anti-interference performance, anti-multipath fading and the ability to improve sy...
