摘要 提出了一种崭新结构的多端口馈电微带漏波天线 ,实现了频率固定下的电控天线主波束逐级可调。在工作频率固定的情况下 ,通过控制双端口馈电微带天线上的中部馈电端口位置 ,使微带漏波天线主波束方向发生偏移。仿真结果表明 ,当工作频率固定为 7GHz的情况下 ,在H平面上 ,主波束扫描范围可以达到约 48°~ 88°。 A new frequency fixed beam scanning microstrip leaky wave antenna is proposed in this paper. The beam scanning ability of the antenna can be achieved with an alternate feed port. The main beam of the antenna may be tilted from 48° to 88° in H plane when the frequency is fixed.
