Abstract

An entire domain moment method analysis of an omnidirectional linear array antenna, in which the radiating elements are slot doublets in a rectangular waveguide, has been developed. A particular feature of the analysis is that direct computation of internal mutual coupling between broadwall slots on opposing walls has been incorporated. Numerical solutions are presented for the scattering properties of the slot doublets in both air-filled and dielectric-filled waveguides. The results are shown to be in good agreement with network analyser measurements
