摘要
针对微带天线带宽较窄的问题,采用基于有限元法的HFSS软件,设计1种以双负材料为衬底的微带天线.仿真计算其反射系数,并给出测试结果.对仿真与测试结果进行比较分析表明,相对于同样尺寸以普通材料为衬底的微带天线,以双负材料为衬底的微带天线的带宽展宽约为50%,在中心频率的相对带宽也达到16.6%.
With the narrow bandwidth of microstrip antenna, a microstrip antenna with the substrates of double negative media is designed by the software HFSS which is based on finite element method, Its reflection coefficient is simulated and the test results are given. The simulation results and the test results are compared and analyzed, and it is shown that the bandwidth increases 50% compared with the same size of the microstrip antenna with ordinary materials, and the relative bandwidth reaches 16.6% in the center frequency.
