Kind Code:
A1
Abstract:
The present application provides an antenna array, comprising a reflection plate, a radome, multiple radiation pieces, multiple subarray feed plates, and multiple isolation metal pieces fixed onto the subarray feed plates. The reflection plate comprises a reflection plate body, multiple grooves formed by the reflection plate body recessed in the direction distant from the radome, and several annular metal walls extending from the reflection plate body to the radome. Each metal wall is correspondingly provided with several grooves. The radiation pieces are fixed on an inner surface of the radome facing the reflection plate. Each subarray feed plate is provided in one metal wall, covers the grooves therein, and encloses with each groove to form an antenna cavity. The radiation pieces are arranged opposite the antenna cavities, and have a one-to-one correspondence to the antenna cavities. Compared with the related technology, the antenna array of the present application is high in isolation, easy to produce, and high in reliability.
