一种小型半U型缝折叠超宽带微带天线
A Compact UWB Folded Half U-slot Microstrip Antenna
摘要
Abstract
A novel fourth wavelength folded ultrawideband (UWB)microstrip antenna is presented in this paper. This patch antenna with shorting wall is cut a half u-slot and part of the patch is folded to the ground plane. The proposed small antenna has UWB characteristic with size of 18 mm × 7.5 mm × 7 mm,it is about 0.23λg × 0.10λg × 0.09λg,whereλg is the wavelength of the lowest working frequency in medium. The simulated results show that the antenna has impedance bandwidth of 39.3%,stable radiation patterns and average gain of 4.3 dB. The antenna model has been fabricated and measured by vector network analyzer E5071C. The mea-sured bandwidth shows that the relative bandwidth of 50.53% from 3.86 GHz to 6.47 GHz is obtained. Mean-while,it also shows that the relative bandwidth of proposed antenna is over 82.6% from 3.53 GHz to more than 8.5 GHz when bandwidth standard is Voltage Standing Wave Ratio(VSWR)<3.关键词
