Load-independent equivalent circuit model for transverse waveguide slots

An LCT equivalent circuit model for waveguide slots was proposed and results obtained from the circuit analysis exhibited very good agreement with the full-wave solution over the entire frequency band of interest. The use of this model to solve a variety of waveguide coupling and radiation problems was illustrated by the analysis and design of a number of waveguide slot-based structures. Problems involving slot arrays were also considered, where the formulas for the slot parameters were employed to facilitate the synthesis problem.
