| 摘 要： | 提出一种电磁带隙结构交错排列的单脊波导缝隙相控阵天线,并与相同尺寸的普通单脊波导缝隙相控阵天线作比较。测试结果表明该天线的方向图得到了明显的改善,单元之间的耦合系数减小,背瓣的辐射电平显著降低,扫描特性得到了改善;同时也说明了电磁带隙结构可以取得比扼流槽更好的抑制表面波的效果。这对于提高单脊波导缝隙相控阵天线的辐射性能具有重要意义。

| Abstract: | A single ridged wave-guide slot phased antenna(SRWSPA) with a photonic band-gap structure which is alternately arranged on the antenna is presented.Another antenna with identical dimensions on a metal ground plane is also included,so that a direct performance comparison can be made.Measured data shows an obvious improvement of radiation pattern,a reduction of coupling coefficient between elements,a significant reduction of back lobe and an improvement of scanning performance.Meanwhile it also proves that the structure is more effective to suppress the surface wave than the choke ring.This is significant in improving the radiation performance of the single ridged wave-guide slot phased antenna. |
