Abstract

The invention belongs to the technical field of base station antenna arrays, and discloses a high-isolation 5G base station antenna and a wireless communication terminal. A metal floor is fixedly provided with a first layer of periodically arranged patch structure and a second layer of periodically arranged patch structure through dielectric studs; periodically arranged square patches are arranged on each layer of periodically arranged patch structure; the first layer of periodically arranged patch structure and the second layer of periodically arranged patch structure are located on the antenna units, and a metal isolation wall is arranged between the antenna unit linear arrays and is fixed on the metal floor through screws. According to the antenna array, the slotted metal isolation wall and the two layers of periodically arranged patch structures are loaded on the antenna array, so that the isolation degree between the antenna array units of the 5G base station is greatly improved, and the antenna array can be applied to a 5G communication system.

Description

technical field [0001] The invention belongs to the technical field of base station antenna arrays, and in particular relates to a high-isolation 5G base station antenna and a wireless communication terminal. Background technique [0002] At present, with the rapid development of wireless communication technology in recent years, the requirements for faster data transmission rate and larger transmission capacity are becoming more and more urgent, and the current fourth-generation mobile communication system will be difficult to meet. The Sub-6GHz frequency bands planned by the Ministry of Industry and Information Technology for the research and development of my country's 5G technology are 3.3-3.6GHz and 4.8-5.0GHz. With the announcement of the 5G mobile communication frequency band, the traditional base station antenna is no longer sufficient to cover its working frequency band. Therefore, as the most important functional component in mobile communication, the technical re...
