| 摘 要： | 在圆形单极天线的基础上进行改进设计了一款梯形接地板结构的超宽带单极天线。根据接地板电流的分布强弱,削去矩形接地板两端对电流影响较小的三角形形状部分,构成梯形接地板。经过仿真优化实验结果表明,该天线电压驻波比VSWR2的阻抗带宽为3.1~17 GHz,工作频段内具有全向辐射特性,且天线只有20 mm×22 mm×1.6 mm,结构简单,适合超宽带无线通信系统的要求。

| Abstract: | An ultra wide band monopole antenna with a trapezoidal ground plate is proposed based on the circular planar monopole antenna. The antenna is made by removal of the two symmetric triangles of the rectangular ground plate in consideration of the current distribution. The experiment results show the antenna with a compact size equal to 20 mm×22 mm×1.6 mm consist of a impedance bandwidth reaches 3.1-17GHz when VSWR is less than 2 and has omnidirectional radiation within the impedance bandwidth.The antenna fit the requirement of ultra-wideband wireless communication systems. |
