| 摘 要： | 传统形式上的微带贴片天线虽具有体积小、重量轻的特点,但窄带特性却制约了其工程应用的范围。在对曲边蝶形天线结构和特性理论分析的基础上,使用Ansoft公司的HFSS三维电磁场软件对其进行建模仿真,最终优化得出了在0.8～3.0GHz宽频带范围内都具有良好的辐射特性,且在工作带宽内VSWR<1.5的曲边蝶形微带天线,在小型化的基础上实现了微带天线的宽频带特性。

| Abstract: | The traditional microstrip antennas have compact size and light weight,but they have narrow frequency band characteristics which restrict their application scope.Based on the analysis of its structure and characteristics,a bow-tie microstrip antenna is simulated with the help of the software HFSS.The result of the simulation indicates that the frequency bandwidth of such antenna is from 0.8 GHz to 3.0 GHz,with the VSWR1.5,which realize the wide bandwidth as well as the compact size. |
