手机双带平面天线的研究与实现

摘要

A dual⁃band antenna with a planar structure for mobile phone is designed and studied.The operating frequency ranges from 880 MHz to 960 MHz and from 1 710 MHz to 2 690 MHz.The purpose of research is that the antenna can cover the GSM,3G and 4G mobile communication.The simulation research and optimization design are implemented by using high frequency structure simulator (HFSS).The experimental model is constructed to measure its voltage standing⁃wave ratio and the radiation pattern.The comparison shows that theoretical and experimental results are in good agreement,and the designed antenna has a certain engineering application value.%设计研究了一款平面结构的双频带手机天线，工作频率范围为880～960 MHz和1710～2690 MHz，研究目标是天线能够覆盖GSM、3G和4G移动通信，采用HFSS进行了仿真研究和优化设计。制作了实验模型，并对其驻波特性和方向图特性进行实测，理论与实验比较取得较好一致性，表明天线具有一定的工程应用价值。
