Patch Loaded Based Ultra-wideband Notch Antenna Design

文章设计一种基于贴片加载的开槽超宽带陷波天线,天线采用微带线-槽线馈电,通过加载贴片实现陷波功能。经过仿真与实测,结果显示该天线在3.03gHz~15.88gHz的频带内电压驻波比(VSWr)小于2,其中在5.14gHz~5.93gHz具有陷波特性,增益抑制最大值达到9.3db,仿真结果与实测结构匹配良好。The slotted ultra-wideband notch antenna was designed based on the patch loaded.The antenna with a line-slot line feed,achieves notch by loading patch.Simulation and experimental results show the antenna band VSWR<2 within 3.03 GHz～15.88 GHz,with a notch at 5.14 GHz～5.9 GHz,and the maximum gain suppression of 9.3 dB.Simulation results match well with the experimental results
