摘要

In this article, a four-way waveguide power divider is proposed for W-band applications.rnThe waveguide power divider employs an improved H-plane T-junctionrnconfiguration. With the introduction of a metallic tetrahedral protrusion into thernwaveguide junction, good impedance matching can be achieved within a wide frequencyrnrange. First, a two-way power divider is designed and analyzed, achievingrnalmost identical amplitude and phase response at its two output ports. Then, otherrntwo same T-junctions are cascaded, respectively, at the two output ports of the twowayrnpower divider to realize the proposed four-way power divider. The four-wayrnpower divider has been optimized, fabricated, and measured. The measurementrnresults agree with the simulation ones reasonably, which demonstrates that the inputrnreturn loss of the proposed four-way power divider maintains above 14 dB across thernentire W-band with an insertion loss of less than 1.3 dB. Therefore, it could find widernapplications in W-band power splitting and combining modules.
