Abstract :
Several techniques for calculating mutual coupling between waveguide-fed slots are discussed. It is assumed that slot lengths are close to their resonant values at the operating frequency. Particular attention is given to spatial domain computations, spectral domain techniques, and the multiple expansion technique. The methods considered are applicable to slots in a ground plane, microstrip patches, and dipole arrays.<>
