| 摘 要： | 微带贴片天线以其馈电方式和极化制式的多样化以及馈电网络、有源电路集成一体化等特点而成为印刷天线类的主角。本论文采用HFSS仿真软件对单馈单层矩形微带贴片天线进行了设计和仿真。此次设计的1．85GHZ和2．45GHZ的双频贴片天线，在两个频点处，反射系数都低于-25dB，输入电阻都约为50欧姆，且电抗很小，达到了良好的匹配效果，辐射场量在两频点处分别约为2dB和4dB，符合小尺寸指标要求。

| Abstract: | Microstrip patch antenna with its feed electric mode and polarization standard diversification and feed network, active circuitry Integration features printed antennas like the protagonist. This thesis is the design and simulation of single-feed single-layer re- ctangular microstrip patch antenna using HFSS simulation software. The design 1.85GHZ 2.45GHZ dual-band patch antenna, in both frequency point, the refleetion coefficient is less than-25dB, the input resistance of approximately 50 ohms anti the reactance is small, to achieve a good match The amount of radiation field in the two frequency points at approximately 2dB and 4 dB meet index requirements of small size. |
