|1. (WO2018120709) TRIPLE-BAND ULTRA-WIDEBAND BASE STATION ANTENNA|
|Applicants:||SHENZHEN GRENTECH CORPORATION LIMITED
|Title:||TRIPLE-BAND ULTRA-WIDEBAND BASE STATION ANTENNA|
A triple-band ultra-wideband base station antenna, comprising a reflection plate, radiation arrays arranged on the front face of the reflection plate and a feed network arranged on the back face of the reflection plate, wherein the radiation arrays are connected to the feed network; the radiation arrays comprise a low-frequency radiation array and two high-frequency radiation arrays; the two high-frequency radiation arrays are symmetrically distributed on the two sides of the low-frequency radiation array; the low-frequency radiation array comprises N low-frequency radiation units, wherein the N low-frequency radiation units are arranged on the front face of the reflection plate at intervals in the longitudinal direction of the reflection plate; and each high-frequency radiation array comprises (2N+1) high-frequency radiation units, wherein the (2N+1) high-frequency radiation units are arranged on the front face of the reflection plate at intervals in the longitudinal direction of the reflection plate, and N is a positive integer which is greater than or equal to 1. In the present invention, the antenna has a compact structure, a small size and a light weight, and has better radiation performance and circuit performance.
