Analysis of a distributed slot discontinuity in the ground plane of a microstrip line

This paper presentsa a method of analysis of distributed slot discontinuity in a microstrip line ground plane based on transverse resonance technique. The scattering characteristics of symmetrical and nonsymmetrical slot resonators of a complex shape have been calculated by Galerkin’s procedure and taking into account the harmonics of current density in the microstrip line and waveguide modes in the slot aperture.
