A miniaturized dielectric-loaded rectangular waveguides, which were used as array elements, were investigated. A lower frequency array that allows larger interelement spacing was embedded onto the base array, by replacing every after some number of the base array elements with lower frequency elements. The dielectric-loaded hard-walled quasi-TEM rectangular waveguide offered an alternative solution preserving the TEM behavior. It was concluded that operating the dielectric-loaded rectangular waveguide elements of an infinite planar array within the vicinity of the TEM frequency gives rise to the best transmission.
