摘要

传统的对称阵子天线一般是全向天线,但是增益较低。微带天线增益虽然较高,但是天线增益方向非全向。本文将串联馈电技术和天线阵列技术相结合,设计了一种中心频率工作于2.45 GHz的PCB全向天线阵。该天线的工作频带为2.35~2.55 GHz,相对带宽达到8%,在此频带内电压驻波比(VSWR)<1.5,增益大于6.0d Bi,同时尺寸较小,能较好地满足Wi Fi频段无线通信系统的要求。
A conventional dipole antenna has the inherent drawback of low gain and a conventional microstrip antenna has higher gain, but it's radiation direction is not omnidirectional. Based on the serial feed and antenna array technology, a novel PCB omnidirectional antenna is presented. The antenna bandwidth with VSWR<1.5 is from 2.35~2.45 GHz and the relative bandwidth is 8%. In addition, the antenna gain is larger than 6.0 d Bi with a smaller size. It is suitable for Wi Fi wireless communication systems.
