摘　　要：介绍目前应用于微波平面电路小型化领域的DGS结构,通过仿真试验研究了DGS结构对耦合微带双线的影响,基于仿真结果设计小型化、结构简单的超宽带高通滤波器,并制作实物进行测量,实测数据与仿真结果基本吻合。The defected ground structure（DGS） which is applied to the field of microwave planar circuit miniaturization is presented. The impact of DGS on coupled micro-strip is studied by simulation experiment, a ultra-wideband microwave high-pass filter with miniaturization and simple structure based on simulation result is designed, and the real circuit is built and measured, the simulation result of the high-pass filter agrees well with the performance of the real circuit.
