摘要

介绍了用于超宽带通信系统的微带线馈电的减小地平面效应印刷天线的设计与分析。仿真结果表明，通过在辐射处切割椭圆贴片，该天线在10db回波损耗下可获得2.1 ~ 13.8 GHz的宽工作带宽。特别是，通过切断散热器的贴片，地平面对阻抗性能的影响大大降低，因为在较低的边缘工作频率下，地平面上的电流被显著抑制。除了15mm x15mm的小尺寸外，该天线在整个UWB带宽上具有高增益的三维全方位辐射。该天线具有良好的带陷波特性，其驻波比在阻带的峰值为8。

An Elliptical Patch UWB Antenna with Reduced Ground Plane Effect

The design and analysis of printed antenna with the reduced ground plane effect, fed by micro strip line for Ultra Wide Band (UWB) communication systems is presented. The simulated results indicate that by cutting an elliptical patch at radiator, the proposed antenna yields a wide operating bandwidth of 2.1-13.8 GHz for-10dB return loss. In particular, the ground-plane effect on impedance performance is greatly reduced by cutting the patch from the radiator because the electric currents on the ground plane are significantly suppressed at the lower edge operating frequencies. In addition to being small in size of 15mm x15mm, the antenna presents three-dimensional omni directional radiation across the entire UWB bandwidth with high gain. The proposed antenna has satisfactory band notched characteristics with the peak value of the VSWR in the stop band is 8.
