摘要
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;从蜂窝移动通信、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。
Third Generation Mobile Communications has challenged a lot to the antenna for its miniaturization and multi--band. A planar inverted--L antenna is proposed, loaded with two U--shaped slots and circular--sides, and fed by a single microstrip. For the use of antennas 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 mierostrip antenna~ s miniaturization and multi--band.
