| 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 applioations., 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 to. 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. |
