摘要
本文提出了一种新型的具有锥状波束辐射方向图宽带天线。该天线的工作频率范围为6.14 GHz至20.37 GHz。该天线结合了渐变型单圆锥、弯折短路金属柱,锥形金属腔和同轴馈电,提供了宽频带和锥状波束辐射方向图,并且具有较高的增益。仿真结果表明,该天线的阻抗带宽(VSWR<2.0)为118.5%。该天线在整个频率范围内保持良好的锥状波束,且工作频率12 GHz处最大辐射增益为7.8 dBi。该天线具有低剖面、低成本和高功率容量等优点。
In this paper,a new broadband antenna with conical beam radiation pattern is proposed.The operating frequency range of the antenna is 6.14 GHz to 20.37 GHz.The antenna combines a tapered single cone,a bent short-circuit metal column,a tapered metal cavity and a coaxial feed to provide a broadband and conical beam radiation pattern,and has a high gain.The simulation results show that the impedance bandwidth(VSWR<2.0)of the antenna is 118.5%.The antenna maintains a good conical beam in the whole frequency range,and the maximum radiation gain at the operating frequency of 12GHz is 7.8dbi.The antenna has the advantages of low profile,low cost and high power capacity.
