摘要

针对安装空间受限且需要与安装壳体共形的需求

设计了一种工作于2.4 GHz频段的圆环形微带贴片天线.利用Ansoft HFSS软件建立了天线及其安装壳体的模型

通过仿真分析确定了天线的外形尺寸以及加载电阻的阻值.仿真结果表明:辐射贴片的外形尺寸与天线的谐振频率密切相关

尺寸增大会使谐振频率明显下降;增大加载电阻的阻值可有效降低天线的谐振频率;嵌入钢壳后天线的谐振频率提高了4.2%.利用矢量网络分析仪对天线嵌入钢壳后的特性进行了实测

测试结果与仿真结果吻合良好.

Abstract

Considering the requirements of limited mounting space and conformal structure

an annular ring microstrip patch antenna working in 2.4 GHz band was proposed.The antenna and its mounting shell were modeled by using the software of Ansoft HFSS

and the key parameters

such as the patch sizes and the resistance of loading resistor

were optimized by simulation.The simulated results indicate that the patch sizes have a great influence on the resonant frequency of the antenna

as the sizes increased

the resonant frequency decreased obviously.It is also found that the resonant frequency can be decreased when increasing the resistance of the loading resistor

and the resonant frequency increased by about 4.2% as the antenna embedded in the steel shell.The antenna with the steel shell was measured by using a vector network analyzer

and the measured results show good agreements with the simulated ones.
