摘　　要：本文提出了一种结构简单的小型化超宽带微带天线,尺寸为28 mm×30 mm.天线采用渐变馈线对酒杯状贴片馈电,接地板采用缺陷地的结构.天线参数采用电磁仿真软件CST进行仿真和优化.测量结果显示该天线在S11小于-10 dB时,相对带宽是170.1%(2.4 GHz^30 GHz).实际制作了天线的样品并进行了测试,实测与仿真吻合良好.A compact ultra-wideband micro- strip antenna with the size of 28 mm × 30 mm is presented in this paper. The antenna uses the tapered feeder to feed the glass-like patch, and the defected ground structure is etched on the back of the antenna. The performance of the antenna is simulated and optimized by CST. The measured result shows that the relative bandwidth of the antenna is over 170.1% （2.4-30 GHz） while the S- parameter is less than - 10 dB. An antenna is fabricated and tested, and the measured results agree with the simulated well.
