N2 - Self-dual structures, ones that remain unchanged under interchanging electric and magnetic portions of the structure where ϵ r = μ r , except for a 90° rotation around their axis, have been shown [1] to produce perfect zero backscattering to an arbitrarily polarized, normally incident plane wave. This phenomenon can be used to create inherently matched radiating apertures made of point-like elements. In [2] , the radiation characteristics of such elements were presented, showing that the element patterns are quite similar to those of an isolated element in free space, being fairly well-behaved and free of blind spots. In this work, we further elaborate on the feeding and matching of these elements in a waveguiding network, with the radiation taking place into a waveguide simulator environment.
