“伞”型双阻带超宽带单极天线的设计

内容简介：为克服无线通信中系统间的相互干扰，基于天线频段抑制技术，设计一款具有双阻带特性的新型超宽带单极子天线。采用加载、开槽等技术，使其在26．～146．GHz频带内回波损失小于-10 dB。通过在接地板和辐射贴片上开槽，使其在IEEE8021．6的33．～36． G Hz、C波卫星通信系统37．～42． G Hz、IEEE8021．1a的51．5～58．25 G Hz频段内驻波比大于2。仿真与测试结果表明，该天线具有良好的抑制功能，并且结构简单，体积小。

Abstract：In wireless communication systems ,in order to overcome the mutual interference among systems ,an UWB monopole antenna with dual band-notched characteristic is proposed using band-suppressed technology .Using the techniques of loading and slotting makes the returned loss of the antenna less than-10 dB in the band of 2 .6~14 .6 GHz .Through slotting on the ground plane and the radiating patch ,VSWR is greater than 2 in the range of IEEE802 .16 of 3 .3 ~ 3 .6 GHz ,C-wave satellite communications system 3 7.~4 .2 GHz ,and IEEE802 1.1a of 5 1.5~5 .825 GHz frequency band .Results of simulation and test show that the antenna has good function of suppression ,simple structure and small size .
