Abstract
In this paper, a fixed-frequency beam-scanning leaky wave antenna (LWA) based on groove gap waveguide (GGW) technology is presented. The whole structure can be divided into GGW and radiating units. The radiating units are composed of 67 slot-coupled patch antennas, and the working state of each patch antenna is controlled by a PIN diode. A periodic reconfigurable method is adopted to realize the fixed frequency beam scanning characteristics of the antenna. Through full-wave simulation, it is found that the proposed GGW L W A can achieve beam scanning of -21 °~29° at 22 GHz.
提出了一种基于沟槽波导技术的固定频率波束扫描漏波天线。整个结构可分为GGW和辐射单元。辐射单元由67个槽耦合贴片天线组成，每个贴片天线的工作状态由PIN二极管控制。采用周期可重构方法实现天线的定频波束扫描特性。通过全波仿真，发现所提出的GGW L W A在22 GHz时可以实现-21°~29°的波束扫描。
