“…Waveguide-based power dividers, as essential components in microwave and millimeter-wave (mmW) systems, have been extensively used in modern solid-state transceivers, because of their distinct advantages including low insertion loss, broad operation bandwidth, and high power capacity. [1][2][3][4][5][6] Various configurations of waveguide T-junction power dividers can be designed to satisfy particular requirements in different wireless communication systems. For instance, E-plane Tjunction dividers are attractive for microwave or mmW power amplifier modules demanding output signals with opposite phases, whereas H-plane T-junction dividers are preferred when in-phase output signals are needed.…”

In this article, a four‐way waveguide power divider is proposed for W‐band applications. The waveguide power divider employs an improved H‐plane T‐junction configuration. With the introduction of a metallic tetrahedral protrusion into the waveguide junction, good impedance matching can be achieved within a wide frequency range. First, a two‐way power divider is designed and analyzed, achieving almost identical amplitude and phase response at its two output ports. Then, other two same T‐junctions are cascaded, respectively, at the two output ports of the two‐way power divider to realize the proposed four‐way power divider. The four‐way power divider has been optimized, fabricated, and measured. The measurement results agree with the simulation ones reasonably, which demonstrates that the input return loss of the proposed four‐way power divider maintains above 14 dB across the entire W‐band with an insertion loss of less than 1.3 dB. Therefore, it could find wide applications in W‐band power splitting and combining modules.
