摘　　要：设计了一类具有正方形嵌套结构的新型分形多频对称振子天线。振子由一系列相似的正方形单元嵌套组成。天线能够同时工作于多个频率,这些频率涵盖了WLAN系统所要求的2.4 GHz/5.2 GHz/5.8 GHz三个频率,采用三维电磁仿真软件CST MWS^(?)软件进行了仿真研究,得到了平衡微带线馈电的对称振子天线的模型。制作了天线实物并进行测试,实验结果与仿真结果吻合较好,验证了设计思路的正确性,该类天线还具有较小的尺寸,且设计思路易于推广到其他形式的嵌套结构中,在多频天线领域具有广泛的应用。A kind of novel muhiband dipole antenna with square-nested fractal are proposed and designed, which are nested with a series of similar square elements. The antenna can synchronously operate in multiple frequencies, covering the three required frequencies, 2.4 GHz/5.2 GHz/5.8 GHz, for WLAN application. The antenna is simulated by CST MWS , a 3-dimension full-wave electromagnetic simulator, then model of the proposed antenna fed by balanced microstripline has been obtained. Finally, prototype of the antenna has been manufactured and measured in anechoic chamber. The results well match the simulated, which verifies the feasibility of design idea. Moreover, these antennas are miniature and the design idea can be easily applied into other types of nested structure, the features of which make the proposed antennas have promising application in muhiband fields
