摘要

利用CST Microwave Studio软件对传统微带天线和带单元的CSRR天线的参数和性能进行了比较。两者的结构规格相同,工作频率为3.5 GHz。仿真结果表明,基于CSRR超材料单元的微带天线在回波损耗、驻波比、增益、带宽、阻抗基准、指向性和辐射方向图等方面均优于传统微带天线。结果表明,CSRR超材料单元在天线上的存在可以提高天线的性能,使天线尺寸小型化,比传统微带天线的尺寸缩小49.44%。它有望应用于WiMAX。所设计的天线满足制造标准或匹配要求。

Design of microstrip patch antenna based on Complementary Split Ring Resonator metamaterial for WiMAX applications
This study compares the parameters and the performances of conventional microstrip antenna and the antenna with cells of CSRR designed by using CST Microwave Studio software. Both of them are constructed with the same specifications and operated at frequency of 3.5 GHz. Based on the simulation results obtained, the microstrip antenna with cell of CSRR metamaterial provide better parameters and performances than the conventional microstrip antenna in terms of return loss, VSWR, gain, bandwidth, impedance reference, directivity, and radiation pattern. It indicates that the presence of cells of CSRR metamaterial on antenna could improve performances and miniaturize antenna dimensions with size of 49.44% smaller than conventional microstrip antenna. It is expected to be able to apply to the WiMAX. The designed antenna has met standards or matching for being fabricated.
