| 摘 要： | 给出一种应用于无线通信的极化分集天线.该天线结构简单紧凑,由两个方向垂直的T形天线单元实现线性极化分集.通过在接地板上开L形的槽,实现了天线的小型化,同时提高了两个端口的隔离度.仿真和测量结果表明,所实现的天线工作在2.4 GHz,在两个端口上,回波损耗小于-10 dB的带宽大于30%,两端口隔离度基本在-20 dB以下.测量结果与仿真结果基本吻合.

| Abstract: | This paper presents a polarization diversity antenna for wireless communication.The antenna has a simple and compact structure,and it has two vertical T antenna elements,which can provide polarization diversity.To further increase the isolation between the two ports,two L-shape slots are etched on the ground,which also achieve the miniaturized antenna.The results show that the proposed antenna works at 2.4 GHz,and has a bandwidth of over 30% with return loss less than-10 dB,and the isolation is less than-20... |
