小型化多频带微带天线的设计

内容简介：第三代移动通信对天线的小型化和多频带提出了越来越高的要求,提出了一种双U型槽和弧形边联合加载的平面倒"L",天线,采用微带馈电;从烽窝移动通信、全球定位系统和蓝牙通讯对天线的要求出发,设计了两个四频天线;一个覆盖GSM/DCS/PCS/ISM频段,另一个覆盖GSM/GPS/PCS/ISM频段;应用ANSOFT公司的HFSS10.0三维仿真软件,对天线进行设计和优化,最终得到了两个基本符合频段带宽及方向图要求的四频天线,这对微带天线的小型化和多频带技术具有一定的指导意义.

Abstract：Third Generation Mobile Communications has challenged a lot to the antenna for its miniaturization and multi-band. A pla-nar inverted-L antenna is proposed, loaded with two U-shaped slots and circular-sides, and fed by a single microstrip. For the use of an-tennas in Cellular Mobile Communication, Global Positioning System and Bluetooth Communication, the paper designs two four-band an-tennas, one includes bands of GSM/DCS/PCS/ISM, and the other includes GSM/GPS/PCS/ ISM. Better parameters of every four bands and radiation pattern can be achieved using the optimizing function of software HFSS10. 0 of ANSOFT company. This design contributes researches of the microstrip antenna' s miniaturization and multi-band.
