Abstract

The invention discloses an antenna array, by setting three substrate layers, attaching patches with different sizes to a first metal layer surface in a first substrate layer, setting a coupling slot at a metal layer in a second substrate layer, setting a feed microstrip as a metal layer in a third substrate layer, and setting at least one metal through hole which surrounds the feed microstrip in the second substrate layer and the third substrate layer, so the antenna array of the embodiment of the invention has high isolation and better broadband performance, and the antenna array has the advantages that various communication performance indexes of the antenna array is improved, the applicability of a large antenna array is improved, and the high integration of the large antenna array is ensured.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna array element. Background technique [0002] At present, in order to achieve high integration, the traditional large-scale antenna array usually adopts a simple form of probe-fed patch antenna element. The patch of this form of antenna element is mostly rectangular or circular, and its bandwidth is very narrow. Usually Only 1% to 7%. In the prior art, in order to make the antenna element have a wider bandwidth, a layer of parasitic patch is usually added on the radiation patch of the antenna element in the above form, but this kind of structure has a large loss of signal strength, and the antenna Signal gain is very low. Another existing way to increase the antenna bandwidth is to use slot coupling feeding. However, when this method is applied to the elements of a large antenna array, due to the strong coupling between the antenna elements, it is necessary to ...
