摘　　要：设计一种满足WLAN双频的T型介质谐振器天线。通过对介质谐振器两侧进行切割形成"T"型产生双频辐射,再由电磁仿真软件建立模型并对其优化,得到最佳的天线设计参数。仿真结果表明该天线实现了5.2 GHz和5.8 GHz的双频带工作且均有很高的增益。该天线结构简单,仅在传统矩形介质谐振器天线的基础上对介质谐振器进行了"T"型处理。A T-type dielectric resonator antenna meeting the requirement of WLAN dual-band was designed. Two sides of the dielectric resonator are cut to form the T-type antenna to produce dual-band radiation. The electromagnetic simulation software is used to establish and optimize the model to get the best design parameters of the antenna. The simulation result shows that the antenna can work at 5.8 GHz and 5.2 GHz,and has a high gain. The antenna has simple structure. The T-type processing for dielectric resonator is only performed on the basis of traditional rectangular dielectric resonator antenna.
