Scattering analysis of H-plane T-junction between fully dielectric-filled rectangular waveguide and partially dielectric-filled parallel-plate

A power divider presented in this paper can be used as a key component in a feeding structure for partially dielectric-filled parallel-plate slot-arrays. Power divider can be cascaded in series in order to feed parallel-plates. Each power diver can be tuned for desired power division and minimum input reflection by coupling window and inductive post respectively. By introducing partially dielectric-filled parallel-plates in stead of fully filled ones, lower equivalent dielectric constant is expected. Such lower equivalent dielectric constant provides simultaneously three important benefits: reduction of dielectric-loss, bandwidth enhancement and slow wave factor.
