摘要
提出了一种S形微带天线,分析并设计了一种工作于S波段的多频微带天线,并采用基于有限元法的电磁仿真软件HFSS10.0对所设计的天线进行了仿真分析对比研究。仿真分析结果表明,该天线-10.0dB的阻抗带宽分别为1.79～1.90GHz、2.08～2.27GHz和2.82～2.95GHz,天线的相对带宽分别达到了5.96%、8.78%和4.81%,天线可以当作宽带天线,用于无线宽带技术通信系统中。
A S shaped multi-frequency microstrip antenna working in S-band is proposed, analyzed and designed. Numerical simulation on this antenna is perfomed with Ansoft HFSS 10.0 a simulation software based on Finite Element Method（FEM）. The simulation results indicate that the inpedance bandwidths of （less than -10.0dB） this antenna are 1.79-1.90 GHz, 2.08-2.27 GHz and 2.82-2.95 GHz respectively, and the relative bandwidths of this antenna are5.96%, 8.78% and 4.81%, respectively. This antenna could be used as a wideband antenna, and is suitable for applications in wireless broadband technology.
