| 摘 要： | 一种新型的不停车收费系统（ETC）车载单元（OBU）的小型圆极化微带天线在文中提出，工作频段为5．8GHz。该天线结构简单，采用高介电常数的底板使天线实现小型化，同时获得了3．4dB左右的增益、H面全向以及右旋圆极化特性，轴比最小仅为0．2dB左右。采用微带馈电方式，使它能容易地与ETC系统车载单元中的其他射频电路连接。

| Abstract: | A novel 5.8GHz circularly polarized miniaturized antenna used in ETC system is presented in this paper.It is characteristic of simple and compact structure.Owing to the high permittivity of the substrate,the size of the antenna is significantly reduced.The gain of about 3.4dB and the omni-directional H-pattern are obtained.It is right-handed circularly polarized,while the minimum value of the axial ratio is about 0.2dB.It is easy for the antenna fed by a microstrip line to be connected with other RF circuit... |
