摘要
本文提出了一种基于基片集成波导的U形双波束漏波天线结构,天线通过周期性缝隙对外辐射电磁能量。通过圆弧过渡结构将漏波天线从一维结构折叠为二维结构的方法,U形漏波天线的长度可缩短31%,同时天线可以对外辐射对称的一对辐射波束,在31GHz至40GHz的工作频带内,每个波束可以在各自的象限中扫描55度的范围,波束也具有良好的增益和方向性。在此基础上,串联的双U形SIW漏波天线在辐射出对称双波束的同时,将长度减小64%。
A U-shaped dual-beam substrate integrated waveguide(SIW) leak-wave antenna(LWA) using periodic slots is proposed in this paper. By folding the waveguide from one dimensional structure to 2D, the length of the U-shaped LWA has reduced 31%. By this configuration, the U-shaped LWA is capable of steering two symmetrical beams within a range of 55 degree when frequency is swept between 31 GHz and 40 GHz. High gain and good directivity has achieved. A cascade of two U-shaped SIW leaky-wave antenna is also presented for the better performance and the length of cascaded U-shaped LWA has reduced 64%.
