设计了一种新型的结构紧凑的四陷波超宽带天线.天线的基本结构由U型辐射贴片、渐变微带馈线和半椭圆形地板组成.通过蚀刻对称的L型槽来抑制WiMAX的干扰;蚀刻圆环形互补开口谐振环(CSRR)以滤除上边带WLAN和下边带WLAN;以及对称的C型枝节来达到在X-band的陷波特性.实验结果表明,天线在超宽带2.58～13 GHz频段内电压驻波比小于2,同时在3～3.8 GHz、5～5.37 GHz、5.6～6.1 GHz和7.15～7.8 GHz四个频段内具有陷波抑制作用,在其余UWB频段内具有良好的辐射特性.天线尺寸小,仅为20×30 mm2.

A novel and compact UWB antenna with four notched hands is presented. The basic antenna consists of a U-shaped radiating patch, a tapered microstrip feed-line, and a semielliptical ground plane. By etching a pair of L-shaped slots, CSRR, a pair of C- shaped stubs and four notched bands are achieved to prevent interference from WiMAX, Lower WLAN, upper WLAN and X-band. Experimental results show that the proposed antenna operates from 2.58 to 13 GHz, except for four stop bands of 3.0~3.8 GHz, 5.0~5.37 GHz, 5.6~6. 1 GHz and 7. 15~7.8 GHz. Good rad...
