【摘要】 一种PCB柱形接地单极振子天线,通过利用PCB双面板的特性,制作出一个双面柱形振子天线,增加了天线的等效直径,展宽了天线的阻抗带宽。仿真结果和测试结果表明,该天线的电压驻波比小于2的带宽可达60%以上;而对新型天线方向性的H面方向图在其频带范围内变化较小,最大辐射方向保持一致,可保证其辐射的全向性。更多还原

【Abstract】 A novel kind of rectangle column monopole antenna is presented.The equivalent diameter of the antenna is thick due to the double rectangular radiation plates connected with the metalized holes.The bandwidth of the rectangle column monopole antenna has been considerably improved.The results of simulation and measurement show that the impedance bandwidth reaches over 60% for VSWR≤2.And from the results of simulation,the radiation patterns have little distortion in H plane when the frequency changes in the bandwidth.更多还原
