摘要

本文提出了一种由微带混合分支耦合器作为移相器在反射模式下馈电的贴片天线阵列的设计。与传统的阵列馈电技术相比，这种拓扑结构允许将FET, PIN二极管或MEMS开关的数量减少两个。对两个天线样机进行了仿真、制作和测量。结果表明，该系统在以5.8 GHz为中心的400 MHz频段内具有良好的波束引导能力，匹配性能良好。

Reconfigurable phased-arrays based on hybrid couplers in reflection mode

This paper presents the design of antenna arrays of patches fed by microstrip hybrid branchline couplers in reflection mode as phase shifters. This topology permits the reduction of the number of FET, PIN diode or MEMS switches by two when compared with classic array feeding techniques. Two antenna prototypes are simulated, fabricated and measured. The results show beam steering capability over a 400 MHz band centered on 5.8 GHz with good matching performances.
