摘　　要：对微带偶极子天线加载引向器,使其定向辐射,实现了一款小型化高增益的差分端射天线。本文给出了该天线详细的设计思路和设计步骤,同时制作了实物并进行测试。结果表明：2~3GHz频带内实测回波损耗（S11）与仿真数据吻合较好,2.45GHz主辐射方向最大增益达到8dB。同时通过容差分析检验了天线的稳定性。以上结果证明该天线具有增益高、定向性强和尺寸小的优点,在4G移动通信和WLAN等领域有较好的应用前景。Loading directors to micro-strip dipole antenna,a high gain（direct radiation）and compact differential micro-strip antenna is presented consequently.Mentality and procedure of the antenna design are give.The antenna is also manufactured and tested.Results show that the return loss is matched well with the simulational results within 2—3GHz,and the maximum gain can reach to 8dB at 2.45 GHz.Moreover,the result of fault-tolerant analysis indicates that the antenna has strong stability.With the advantages of high gain,strong directionality and small size,the antenna can be applied to the fourth generation mobile communication or WLAN.
