Refined characterization of E-plane waveguide to microstrip transition for millimeter-wave applications

This paper presents a new algorithm for the analysis and design of an E-plane waveguide-to-microstrip transition. The theory is based on the generalised scattering matrix technique in conjunction with the spectral-domain approach and space-domain integral equation method. The full 2D current vector distribution on the probe, as well as influence of the dielectric edge, are taken into account for calculation of the generalised S-parameters. Analytical and experimental results are shown for a W-band transition.
