Summary :

A full-wave analysis is presented for computing resonant frequencies and the end effect of slot resonators. The formulation is based upon the spectral domain approach, which was first suggested by Itoh and Mittra. The Fourier transformed admittance Green functions are analytically derived to save computer time. The characteristic equation is obtained by Galerkin's procedure in the Fourier transform domain. It is confirmed that the sensitivity of the solutions to the basis functions is small using different basis functions. The resonant frequencies are shown for different structual parameters. The numerical results of the end effect are in good agreement with the experimental results published by other investigators. This analysis can be applied to the design of microwave integrated circuits used the shorted-slot lines, such as microstrip-slot transitions or slot filters.
