一、引言机载雷达多数采用平板裂缝天线,而平板裂缝用的耦合器又有它本身的特殊要求。主要体现在电气性能上要求耦合器是谐振的耦合缝隙;在结构设计上要求耦合器与辐射波导紧贴在一起。此外由于机载雷达要求体积小,重量轻,因此在设计上带来了许多困难。在一般情况下,是很难把馈电缝与辐射缝分开来进行计算和测试的。作者经过努
I. INTRODUCTION Most airborne radars use flat-panel slot antennas, while flat-slot couplers have their own special requirements. Mainly reflected in the electrical performance requirements of the coupler is a resonant coupling gap; in the structural design requirements of the coupler and the radiation waveguide close together. In addition, as airborne radar requires small size and light weight, it brings many difficulties in design. Under normal circumstances, it is very difficult to separate the feeding seam from the radiation seam for calculation and testing. The author passed through
