The proposed idea was proved by the design of the coplanar waveguide(CPW)-fed slot antenna. The sample design gives a wideband antenna the impedance bandwidth of which covers the frequency ranged from 1.9 GHz to 6.55 GHz.The antenna could be configured to work either in single-band mode or in one of the defined dual-band modes.展开更多
为了避免如WiMax和WLAN等窄带通信系统对超宽带通信系统的影响，该文提出一种具有双陷波特性的超宽带天线。该天线采用圆形贴片作为辐射单元，通过在贴片和接地板上分别开圆弧状的H形槽和L形槽来实现双陷波特性。天线在3.1~10.6 GHz的...为了避免如WiMax和WLAN等窄带通信系统对超宽带通信系统的影响，该文提出一种具有双陷波特性的超宽带天线。该天线采用圆形贴片作为辐射单元，通过在贴片和接地板上分别开圆弧状的H形槽和L形槽来实现双陷波特性。天线在3.1~10.6 GHz的超宽带频段内能够有效地工作并抑制两种不同的窄带通信系统的干扰。同时圆弧状 H 形槽的参数研究表明，这种开槽结构能够以槽参数组合的形式更有效地控制陷波中心频率。实测和仿真结果吻合，该天线实现了良好的陷波功能，在工作频段内有良好的辐射方向特性。展开更多
