Abstract： A kind of compact ultra wideband (UWB) monopole antenna with dual-band notched function is presented. The proposed antenna, using “C” and “L” apertures embedded in the annular ring patch and ground patch, gets two band-notched characteristics in WiMAX3.5 GHz and WLAN 5.5 GHz. The size of antenna is 24 mm×36 mm×1.6 mm. The simulation results show that waveband range of the antenna is 2.7-10.6 GHz for S11＜-10 dB and the band-notched wavebands are 3.2-3.8 GHz and 5.1-6 GHz. So it has miniaturization, ultra-band and band-notched characteristics. Meanwhile, the radition pattern, directivety and gain are perfect, which meets the practical need.

摘要:本文设计了一种小型的具有双陷波特性的环形超宽带单极子天线。 通过在圆环形辐射贴片上开C形缝隙， 在反射板上开L型缝隙， 实现了天线在 WiMAX 3.5 GHz 和 WLAN 5.5 GHz 通信频带内的陷波特性, 天线的大小为 24 mm×36 mm×1.6 mm。 通过仿真可知， 天线 S11＜-10 dB 时， 带宽范围为 2.7-10.6 GHz, 陷波范围为 3.2-3.8 GHz 和 5.1-6 GHz， 实现了天线小型化、超宽带以及陷波的特性， 同时， 天线具有良好的辐射特性、方向性和增益， 能够满足实际需要。
