摘要:

研究了一种单馈条件下双频圆极化微带天线的设计方法,通过开槽的方式实现了小型化,采用辐射边加载实现了阻抗带宽的展宽,采用电磁仿真软件HFSS进行了仿真,得到了天线的VSWR、AR以及增益等指标,对这些指标进行分析后,证明了该天线设计方法的可行性与正确性。

Abstract:

The design of dual-frequency circularly polarized microstrip antenna fed by a single probe is studied.Miniaturization is realized by using slots,and broadband covering by loading the antenna with a patch.The proposed antenna is simulated by HFSS and the results of VSWR,AR,radiation pattern and gain are given,which shows that the antenna design is effective and feasible.
