| 摘 要： | 该文根据通讯系统的具体要求，分析了已有的设计，并且在其基础上设计出了性能更高的微带天线．普通的微带天线带宽很窄，该文采用了一种新型的展宽天线带宽的方法，在微带天线中加入有源网络，使微带天线的相对带宽达到50％，并且在宽频带内微带天线的输入阻抗都得到了很好的匹配．经过仿真分析，得出了各种参数的曲线图，验证了有源天线的优越性．

| Abstract: | In accordance with the specific requirements of communication system, the authors analyzed the existing design, and designed a microstrip antenna with higher performance. Microstrip antenna has very narrow bandwidth. This paper presents a new type of wide bandwidth antenna, taking active network into microstrip antenna so that the relative bandwidth of microstrip antenna is up to 50 percent, and the antenna input impedance has a very good agreement in the broadband. Through simulation and analysis, the curve of various parameters was obtained, and the superiority of the active antenna was verified. |
