一种新型智能手机的平面小型GPS天线的仿真研究

STUDY ON THE SIMULATION OF A NOVEL SMARTPHONE ANTENNA FOR GPS EQUIPMENT

提出了一种应用于手机上的全向GPS天线。它覆盖了两个常用GPS频段:1227.6+/10 MHz和1575.42+/-10 MHz,其回波损耗大于10 dB。天线的主辐射体由两个矩形金属片和四个三角形组成,总体尺寸为20 mm×70 mm×0.8 mm。仿真结果表明所设计天线能达到GPS通信的要求。

An Omni-directional micro-strip antenna for GPS equipment on mobile phone is proposed. It covers two common bands for GPS： 1227.6＋/-10MHz and 1575.42＋/-10MHz, which its return loss is greater than 10dB. With the radiation patch and two rectangular grounds, the size of the presented antenna is 20mm＆×70mm×0.8mm. By the simulated results we can draw a conclusion that the antenna reaches the requirements for GPS communication.
