Analysis of circular microstrip resonators using two-dimensional telegraphists' equations

Abstract

The two-dimensional telegraphists' equations have been used to determine resonant frequencies of an inhomogeneous microstrip circular resonator. The solution technique is simple and equations like (17) and (18) can be easily solved employing computation tools such as Mathematica or Matlab. Other structures, e.g. microstrip resonators with variable dielectric permittivity can also be treated in the manner presented in this paper.
