Abstract :
Measurements on a 275-waveguide-element planar array do not indicate the E plane coupling null predicted computationally on the assumption of an infinite array. A numerical method, utilising the fast Fourier transform, for determining the number of elements required to exhibit the E plane null, is presented with computed results.
