摘要:

提出了一种新型双陷波特性的超宽带单极子天线。通过在介质基板上添加锥形辐射贴片,天线可以覆盖超宽带通信频段。在辐射贴片上引入上、下两个锥形缝隙结构,可以实现3.5 GHz、5.5 GHz的双陷波特性。天线实测模型电压驻波比<2的阻抗带宽是2.56~10.61 GHz,其中3.18~3.76 GHz和4.4~5.75 GHz具有陷波特性。测试表明,天线在工作频带内具有全向辐射特性。

Abstract:

A novel printed monopole antenna with band-notched performance is proposed for UWB applications.,Impedance bandwidth covering UWB band is obtained by using a modified trapezoid strip.In addition,two trapezoid slots are inserted on the FR4 substrate to produce two notched bands at 3.5 GHz and 5.5 GHz.The measurement results show that the proposed antenna can guarantee a wide bandwidth from 2.56 to 10.61 GHz (VSWR<2) with dual notched band at 3.18~3.76 GHz and 4.4~5.75 GHz.Omnidirectional radiation patterns over the operating bands are obtained by the fabricated antenna.

Key words: ultra wideband antenna;monopole antenna;wireless communications;band notched
