摘要
针对无线通信系统对天线宽带化、小型化的要求,本文提出的新型宽带小型天线,是一种通过对天线加载寄生单元,然后对振子排列组合而产生宽带频段的单极天线。该天线具有较宽的阻抗带宽和水平全向的方向图,实测小于-10 dB的频率范围为60MHz—210MHz,与仿真结果基本吻合。这种天线形式结构简单,易于加工,利于在车载电台、移动通信终端推广使用。
The novel wideband antenna presented in this paper is the monopole with parasitic elements to achieve the wideband frequencies by arranging the elements of strategy.There are wider bandwidth range between 60MHz and 210MHz for the impedance below-10dB for the test and horizontally direction of this kind of antenna,which agrees with the simulation results.The antenna structure is simple and easy to get the wider application in the mobile and radio in the vehicles.
