应用于超宽带通信的贴片六边形单极子天线研究

内容简介：设计了一种应用于超宽带通信的平面单极子天线.天线由一个六边形辐射单元和一个部分接地板构成.通过采用了一种新颖的馈电结构,有效地改善了阻抗带宽.天线获得了优良的电气性能,包括较宽的阻抗带宽、全向的辐射方向图、平稳增益及近似常数的群时延特性等.仿真及实验结果得到了合理的一致.

Abstract：A planar monopole antenna is proposed for ultra-wideband (UWB) applications. The antenna consists of a hexagon radiation patch and a partially modified ground plane. A novel feeding structure is proposed to improve the impedance bandwidth. Promising performances are achieved, including wide impedance bandwidth, flat gain, omnidirectional radiation patterns and constant group delay. Reasonable agreement is obtained between the simulations and measurements.
