In this letter, we present a novel four-way divider/combiner in rectangularwaveguide. The design is completely two-dimensional in the h-plane, witheight-fold mirror symmetry, and is based on a recent four-port hybrid design[6]. In combining mode, it can function as a phased array with four inputs andfour outputs. The planar nature of this design provides advantages, such as thefreedom to increase the waveguide height beyond the over-moding limit in orderto reduce field strengths. Along with its open geometry, this makes it idealfor high-power applications where rf break down is a concern. Design criteria,field-solver simulation results, and prototype measurements are presented.
