摘要 通过在超宽带印刷单极子天线上开设不同形状和尺寸的缝隙,设计了一种由共面波导馈电的,具有双频陷波特性的超宽带天线。并且通过对天线仿真结果的分析,总结出了缝隙结构参数对天线陷波特性的影响规律。仿真和实测结果表明,除陷波频带外,天线在3.1到10.6GHz频带上的VSWR小于2,在3.4-3.77GHz和4.91-5.87GHz频段上具有良好的陷波特性,较好地避免了系统与WiMAX及WLAN之间的干扰。在非陷波频段上天线具有较好的全向辐射特性。此外,通过对天线表面电流分布情况的详细分析,推导出了天线的等效电路结构。 A CPW feed dual band-rejection ultra-wideband antenna is achieved by cutting slots of different shape and size on uhra-wideband printed monopole antenna. The relationship between structural parameters of slot and band-rejection characteristic is discussed though simulation and experiment in this paper. The simulated and measured results have shown that the antenna has wideband characteristc from 3.1 to 10.6GHz and good band-rejection characteristic from 3.44 to 3. 77GHz and from 4.91 to 5.73GHz ,which can avoid interference between the UWB system and WiMAX and WLAN. Beside, the antenna has good omnidirectional radiation characteristic on non band-rejection band. In addiation, through the detailed a- nalysis of antenna surface current distribution, the equivalent circuit of antenna is deduced.
