摘要
本文用点匹配法分析了偏心环微带天线的谐振特性,所得公式可将圆形、同心圆环和偏心圆环微带天线作为特例来应用.对偏心圆环谐振波数的理论计算与实验测试的良好一致性表明,这种方法适用于分析任意形状微带天线的谐振特性.偏心圆环较之同心圆环有较宽的带宽.
Resonant characteristic of eccentric ring microstrip antennas has been studied using point-matching moded. The formulation can be appplied to some specific cases, for example, circular, circular ring and eceentric circular ring patch antenna. The good agreement between measured and calculated results of resonant wave-number of eccentric circular ring microstrip antenna indicates that the method can be used to analyse characteristic of arbitrary shape microstrip antennas.
