T. Kezai et Av. Vorst, MODELING RESONANCE IN WAVE-GUIDE-TO-MICROSTRIP JUNCTIONS BY UNILATERAL FIN LINE RESONATORS, IEEE transactions on microwave theory and techniques, 42(2), 1994, pp. 223-226
A method for the rigorous calculation of the resonant frequencies obse
rved in waveguide-to-microstrip transitions is developed. The method i
s general and includes all types of waveguide-to-microstrip junctions.
The resonant parts are modeled as unilateral fin line resonators with
similar shapes. The resonance frequencies are determined by using the
Spectral Domain Approach with appropriate basis functions. Measuremen
ts were made. They are in good agreement with the data computed from t
he model.
