A series of windows in the narrow wall of a fully-dielectric-filled rectangular waveguide to feed partially-dielectric-filled oversized-rectangular waveguide is presented The overall structure is sincle-layer and 3-dimensional however, the waveguide which is uniform along the height is analyzed by the 2-dimensional method of moments and the oversized waveguide which is uniform in the longitudinal direction of the waveguide is analyzed by the 2-dimensional inside matching It is found that utilizing simple mode conversions between the two orthogonally form structures is sufficient for obtaining the results similar to those of a 3-dimensional solver HFSS The parameters for the windows designed for a uniform input division ale presented A simulation shows that a 12 window array provides a 3 5% bandwidth in terms Of reflection below -20dB The uniform excitation of the quasi-TEM wave Is confirmed in the 60 GHz band by measuring a uniform aperture field in amplitude and phase over the slotted oversized-waveguide
