摘要
本文使用时域有限差分法分析了宽缝微带天线的频率阻抗特性，不同的馈电方式对宽缝微带天线阻抗特性的影响，及改善债电带线与缝之间匹配的措施。在分析计算的基础上设计了一种工作于C波段的加脊宽维微带无线，回波损耗大于10dB的相对带宽可达25％。
This paper deals with the analysis on impedance frequency-dependent characteristics of wide-slot microstrip antenna,the effect of different type of excitation on the impedance characteristics,and the improvement of match between the feeder and slot using the Finite-DifferenceTime-Domain Method.A novel C-band wide-slot microstrip antenna with a ridge has been designedon the basis of analysis. The relative bandwidth of the antenna is approxitnate 25 % while the inputreturn loss is less than - 10dB.
