摘　　要：提出了一种新型超宽带(UWB)陷波天线,该天线的结构由常规的圆形单极子天线演变而成。为获得超宽带特性,天线的辐射体被设计成渐变的笑脸形状。同时,通过在辐射贴片上开C形槽来实现陷波特性。合理选择C形槽的尺寸可有效去除超宽带频段内的无线局域网WLAN(5.150~5.825GHz)的干扰。仿真结果表明,天线在4.91~6.07GHz处形成了阻带特性(电压驻波比VSWR>2),天线结构新颖简单,适用于超宽带通信系统。A novel UWB band-notched antenna was proposed in this paper.The configuration of the antenna was evolved from the conventional circular monopole antenna.The radiator of the antenna was designed to a gradient smiley-shaped patch to realize UWB characteristic and a C-shaped slot on the radiation patch was fabricated to realize the band-notched characteristic.The reasonable selection of the size of the C-shaped slot can effectively remove the interference of WLAN（5.150~5.825GHz）in the ultra-wideband.The simulated results indicated that the bandnotched characteristic（VSWR2）was obtained within the frequency range of 4.91~6.07 GHz.The proposed antenna structure is novel and simple and suitable for the ultra-wideband communication systems.
