Spectral domain analysis of an elliptic microstrip ring resonator
Abstract
The quasi-static capacitance of an elliptic microstrip ring resonator is evaluated with the spectral domain technique. The effect of fringing of fields associated with the structure is determined using this capacitance value in terms of the effective eccentricities of the inner and outer ellipses, the effective values of the ratio of the semimajor and semiminor axes, and the effective dielectric constant. The resonant frequency of the even TMc110 mode, calculated utilizing them, is in good agreement with the experiment. Mode charts for the dominant and higher order even and odd TMc(s)m10 resonance modes are also presented.
