矩形微带贴片天线的设计与仿真

内容简介：根据微带天线的辐射原理，对天线参数确定进行了理论分析，设计了一种中心频率为447MHz的矩形微带贴片天线。利用HFSS软件对其进行了建模和仿真验证。仿真结果表明，天线的S参数、方向图和输入阻抗均达到了微带贴片天线的设计要求，基于HFSS软件的设计方法能够快速、高效地完成微带天线的设计，且设计的微带天线具有良好的性能指标。

Abstract：According to the principle of radiation of the microstrip antenna,the antenna parameters were analyzed in theory,and then the rectangular microstrip patch antenna with a center frequency 447MHz was designed.Its modeling and simulation verification were used by HFSS software.The simulation results show that the S parameter,the radiation pattern and input impedance of the antenna are up to the requirements of the microstrip patch antenna design.So the design method based on HFSS software can quickly and efficiently finish the design of the microstrip antenna with good performance.
