Abstract

The effects of differently positioned and combined apertures on the magnitudes of electric coupling coefficients of two identical combline resonators are analysed. Coupling coefficient, k-vertical symmetry provides greater negative coupling for apertures less than 50 % opening on the common wall. Combined apertures do not enhance electric coupling. The Gamma aperture annihilates electric coupling, whereas T shaped aperture provides reduced negative coupling coefficients compared to single apertures that make up the combination.
