摘要： 多频天线能满足多功能通信系统共用一个发射天线的需求，符合系统集成化的趋势.本文通过在正方形微带贴片上开槽与增加销钉的方式，提出一款紧凑型四频微带贴片天线，给出了快速设计流程.改变开槽的大小和销钉的位置可以控制各工作频段的中心频率和输入阻抗，并使用商业软件对天线进行了全波仿真.通过仿真和实测得到天线各工作频段的回波损耗S11参数及辐射方向图，验证了设计思路和天线性能参数.该模型的设计对多系统兼容性天线的设计具有一定意义.

Abstract: The multi-band antenna met the demand of the multi-functional communication systems, corresponding with the trend of the system integration. A four-band compact microstrip patch antenna was proposed by adding a slot and a pin to a square microstrip patch. A fast design procedure was also examined, by which the center frequencies of each operational band as well as the input impedances could be altered by modifying the dimension of the slots and the locations of the pins. The full wave simulations of a prototype were made by commercial software. The simulated and the measured S11 and the radiation patterns during the operating bandwidths were obtained, testifying the design concept and the antenna performance. This model might be used as a multi-system compatible antenna.

Key words: multi-functional communication system, compact, microstrip patch antenna, four-band
