Abstract

This article presents a novel broadband H-plane rectangular waveguide T-junction structure for unequal power dividers at Ka-band. Inspired by H-plane waveguide bend structure and directional coupler, T-junctions with high power splitting ratio are invented. Compared with the conventional T-junction structures, their bandwidths are obviously broadened. Two in-phase power dividers at Ka-band with different power division ratios (1:4 and 1:8) are designed and fabricated to verify the practicability of the proposed structure. The measured results agree well with the simulations and the broadband characteristics are obtained. The bandwidth of unequal power divider is 44.06% for the 1:4 power divider and 38.9% for the 1:8 power divider, respectively.
