Abstract

The invention discloses a dual-polarization micro-base-station MIMO antenna unit, and relates to the technical field of an antenna. The dual-polarization micro-base-station MIMO antenna unit comprises an antenna unit, an isolation wall and a dual-polarization compact type micro-base-station antenna array; the antenna unit comprises a feed plate and a radiation plate; the isolation wall comprises a third dielectric plate and periodically-arranged frequency selection surface (FSS) isolation units; and the dual-polarization compact type micro-base-station antenna array comprises the antenna unit and the isolation wall. Compared with the prior art, the problems of low miniaturization degree, incapability of satisfying broadband frequency requirement and low isolation degree of the micro-base-station antenna can be solved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-polarization micro base station MIMO antenna unit. Background technique [0002] With the high-speed development of wireless communication towards broadband and multi-function, the wireless communication resources provided by the macro base station have insufficient spectrum resources, signal transmission congestion, and blind spots in signal coverage. In order to solve the above problems, micro base station technology has emerged, micro base station Technology is a coverage complement to macro base station technology. Nowadays, more and more densely populated areas and indoors use micro base stations for signal coverage, and realize the requirements of good coverage, easy deployment and installation, high channel capacity and low cost. meet the needs of LTE network development. [0003] MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple trans...
