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。
An S-shaped microstrip antenna was proposed. A multi-band microstrip antenna operating in the S-band was analyzed and designed. The designed antenna was simulated and analyzed by using electromagnetic simulation software HFSS10.0 based on the finite element method the study. The simulation results show that the impedance bandwidth of -10.0dB is 1.79 ~ 1.90GHz, 2.08 ~ 2.27GHz and 2.82 ~ 2.95GHz, respectively. The relative bandwidth of the antenna is 5.96%, 8.78% and 4.81% respectively. The antenna can be regarded as Broadband antenna for wireless broadband technology communication system.
