【摘要】 本文研究了小型化双陷波超宽带天线。采用印刷单极子天线形式,在辐射贴片中央开孔,并在孔位处引入倒T型枝节,同时在地面上加弧形枝节来实现天线的双陷波特性和小型化以及宽频带特性。利用HFSS仿真软件对该天线进行了仿真设计,设计结果表明在频段3.1GHz-10.6GHz内,除了应用于WiMAX系统的3.3GHz～3.7GHz和WLAN系统的5.15GHz～5.35GHz频段之外,实现了宽频带特性。在此基础上,研制了天线实验样机,实测结果表明天线的电特性与设计结果吻合良好,说明了该设计方法的有效性。更多还原

【Abstract】 In this paper,a compact UWB antenna with dual-notched characteristics is proposed.A printed monopole antenna,etched a hole in the radiation patch central,by employing the inverted T-shaped strip in the hole,and the arc-shaped strip on the ground to achieve dual band-notched characteristics,miniaturization and broadband characteristics.The simulated and measured results indicate that the antenna offers a bandwidth from 3.1 GHz-10.6 GHz with VSWR<2,except the dual-notched bands of 3.3 GHz-3.7 GHz(WiMAX) and 5.15 GHz-5.35 GHz(WLAN).Experimental results show that the antenna electrical characteristics and design results are in good agreement,indicating the effectiveness of the proposed method.更多还原
