Abstract

This paper discuss a partially grounded circular monopole UWB microstrip patch antenna having an egg-shaped slot for using in Cognitive Radio (CR). Symmetric semi-circular and rectangular notches are made on the monopole to further increase its performance. The UWB antenna works within the unlicensed band 3.1 GHz - 10.6 GHz. It shows 2.96 GHz - 18 GHz return loss bandwidth and 143.51% percentage bandwidth. The antenna structure was implemented and optimized using CST microwave studio full-wave simulation software.
一种新型超宽带天线在认知无线电中的应用比较研究
本文讨论了一种用于认知无线电(CR)的部分接地圆形单极微带贴片蛋形槽天线。在单极子上设计了对称的半圆和矩形缺口,进一步提高了单极子的性能。UWB天线工作在未授权的3.1 GHz - 10.6 GHz频段内。回波损耗带宽为2.96 GHz ~ 18 GHz,带宽百分比为143.51%。利用CST微波工作室全波仿真软件对天线结构进行了实现和优化。
