内容简介:提出了一种新颖的小型平面超宽带天线。该天线由矩形微带天线的基本结构演变而来,为获得超宽带频率特性,设计时辐射单元下端采用了渐变结构,金属底板使用缺陷地结构。对天线的反射系数、方向图及增益进行了仿真计算和优化设计,实测结果为:天线的工作频段为3.1~13.0GHz(S11〈-10dB),增益大于1dB,具有良好的超宽带特性和全向辐射特性。
Abstract:A novel compact planar antenna for ultra-wideband(UWB) applications is proposed in this paper. Similar to the conventional rectangular mierostrip antenna,a tapered radiating element and defected ground structure on the ground is employed to achieve ultra-wideband characteristics. It is simulated and optimized for its reflection characteristics, radiation patterns and gain. Measurement result within the operation bandwidth is from 3. 1-13.0 GHz, the S11〈- 10 dB, and gain is above 1 dB. It is observed that good ultra-wideband performance and omnidirectional radiation performance have been achieved.
