摘要
提出了一种具有带阻特性的超宽带(UWB)共面波导(CPW)馈电平面圆形单极子天线的设计方法,采用该方法设计的天线完全满足超宽带无线通信所要求的3.1~10.6GHz频带范围,并且通过在圆形贴片上添加U型缝隙实现了4.85~5.87GHz频段上电压驻波比VSWR≥2:1的带阻特性。采用电磁场仿真软件HFSS绘出了天线方向图,仿真结果表明该设计实用、可行。
A design of CPW fed planar circular monopole UWB antenna with band-notched character is presented. This antenna can satisfy the applications of ultra wide-band wireless communications covering 3. 1-10.6GHz band- width, and achieve band-notched character between 4.85GHz and 5.87GHz (VSWR〉2: 1) through adding U-slot on the circular patch. The radiation patterns is illustrated with the electromagnetic simulation software HFSS, and the results indicate that the design is reasonable and practicable.
