摘　　要：设计了1种新型的带状线-双层共地基片集成波导转换方式,该转换方式具有转换尺寸小、损耗低易集成等特点,并将其与基于带状线的平面偶极子天线集成设计,使X波段平面偶极子天线具备低频抑制特性;对所设计的具有低频抑制特性的平面偶极子天线样件进行测试,实测结果证明在基本不影响天线工作频段增益的同时对6GHz以下频段抑制能力提升了25dB以上。A novel strip-line to layer common ground substrate integrated waveguide converter is designed,which has the characteristics of small conversion size,low loss and easy integration.With its integration with dipole antenna based on strip line,the antenna has low frequency suppression characteristics.The designed planar dipole antenna sample with low frequency suppression characteristics is tested.The measured results show that the working band gain of the antenna is basically not affected,and the suppression ability of the frequency band below 6GHz is improved by more than 25dB.
