Abstract: To study the resonant characteristics of eccentric circular and concentric circular-elliptical ring microstrip antennas, the method, which is connected with the concentric ring microstrip antenna and based on the perturbation, is employed to calculate resonant wave numbers. Comparisons of calculations with reference for the fundamental mode are also presented, agreement is very good for small eccentricity.

Key words: resonant wave number, microstrip antenna

摘要: 为研究偏心圆环及同心圆-椭圆环微带天线的谐振特性,运用了一种以对同心圆环微扰为基础的计算方法,计算的谐振波数值与参考文献作了比较,在小偏心率的情况下,一致性很好。
