摘要
利用单极子结构和共面波导特性设计了一种小型化超宽带箭形单极子天线。该天线带宽达到3.9~10.9GHz。使用三维电磁仿真软件HFSS12对天线进行仿真并进行优化,得到回波损耗、电压驻波比,增益等参数,其中回波损耗在3.9-10.9 GHz小于–10 dB,电压驻波比小于2。仿真结果表明该天线符合设计要求,在整个带宽频率范围内具有较稳定的增益和辐射方向性,其可广泛应用于商业超宽带无线通信领域中。
A minitype ultra wide band（UWB） arrow shape monopole antenna was designed by using coplanar waveguide（CPW） characteristics and monopole structure.The antenna was simulated and optimized by using the software HFSS12,then the return loss,VSWR,gains and other parameters were got.The return loss is less than –10 dB in the frequency range of 3.9-10.9 GHz and the VSWR is less than 2.The simulation results show that the antenna reaches the plan requirements,also it possesses stable gains and oriented radiation in the whole range of frequency bandwidth.So the antenna can be wildly used in commercial UWB wireless communication.
