一种新型套筒天线宽频特性的HFSS仿真分析

针对传统套简单极子天线结构变量复杂、要做到3:1的频带宽度难的问题,利用电抗补偿方法设计了一款位于特殊接地铜管上的双层套筒偶极子天线,并利用HFSS软件对结构进行仿真分析,找到影响频带及反射特性的结构参数,通过软件自带的优化功能,对各个参数进行仿真优化,得到工作在800-960MHz,1710-1920MHz,2400-2483MHz频带范围内驻波系数低于1.5的实用套筒天线结构,包含目前移动通信所用频带:2G、3G和WLAN.天线在同一个结构上实现多频工作,且在各个频段内反射很小,节省了天线资源,利于系统集成.

A Study of Broadband Characteristics of a Novel Sleeve Dipole Antenna

In view of the complicated structure variables and the difficulty of implementing 3:1 frequency band of traditional sleeve pole antenna,a reactance compensation method is used to design a double deck antenna located on a special copper tube grounding.The structure parameters about broadband characteristics and reflections are found out by using HFSS simulation software and are optimized with the optimizing function,so a practical sleeve antenna is designed,whose frequency bands are 800MHz to 960MHz,1710MHz ...
