摘要
提出了一种新型带移相器多端口馈电微带漏波天线 ,实现了频率固定下的相控微带漏波天线双向主波束扫描。通过控制微带漏波天线中部馈电端口移相器 ,成功实现了工作频率固定下微带漏波天线主波束扫描 ,并使用电子开关实现微带漏波天线主波束双向扫描。当工作频率为 7GHz时 ,在微带漏波天线法线右侧 ,主波束扫描范围约为 4 1°～ 6 3° ;在微带漏波天线法线左侧 ,主波束扫描范围约为 117°～138°。
A novel frequency-fixed beam-scanning microstrip leaky-wave antenna with phase-shifter has been described in this paper. Through a new feeding construction with phase-shifter, the main lobe of the pattern of the microstrip leaky-wave antenna can scan at a fixed frequency. When the working frequency is 7 GHz, the main lobe may scan from 41° to 63° or 117° to 138°.
