摘要
Abstract
A miniaturized ultra-wideband(UWB)printed PICA(planar inverted cone antenna)-like monopole antenna is presented. The radiating element of this antenna is made up of PICA-like patch which is fed by microstrip line. The window of the defected ground structure(DGS) is etched on the ground plane. The antenna has a small overall size of 25 mm × 23 mm × 1.6 mm. Compared with the previous antenna,the size was decreased by about 33%. The impedance bandwidth,radiation pat-terns and gain characteristic of the antenna were analyzed and optimized The results show that the 10 dB return-loss bandwidth is from 3 GHz to 11 GHz and the relative impedance bandwidth is about 114%,which covers up the total UWB frequency band. The consistent gain in the total frequency band is 3~4 dB.关键词
