摘要 提出了一种崭新的带移相器双端口馈电微带漏波天线。通过控制微带漏波天线末端馈电端口移相器 ,其输入电流激励相位发生变化 ,成功地实现了工作频率固定下的微带漏波天线主波束扫描。当工作频率为 7GHz时 ,微带漏波天线主波束扫描范围可以达到约 2 1°。 A novel frequency fixed beam scanning microstrip leaky wave phased antenna ha s been developed. Through a new feeding construction with phase shifter, the ma in lobe of the pattern of the microstrip leaky wave antenna can scan at a fixed frequency. When the working frequency is 7GHz, the main lobe may scan from 41° to 63°.
