摘要 研究了基于皱褶软地表面的微带天线。通过对普通微带天线和采用软地表面的微带天线的输入回波损耗、辐射方向图、带宽和增益等的比较 ,发现该结构的软表面可以增加天线的带宽 ,抑制天线的背瓣 。 A microstrip patch antenna with a corrugated soft ground surface is presented. T he input return loss, radiation pattern, frequency bandwidth and gain of the des igned patch antenna are compared with those of a conventional patch antenna. The results show that this type of soft surface improves the frequency bandwidth, s ignificantly suppresses the back lobe, and widen the beam in the H plane.
