A post-wall waveguide slot array with a three-way power divider on a single-layer substrate is designed to have a H-plane sectoral beam and an E-plane cosecant pattern with null-filling. Experiments in the 26 GHz band confirmed the sectoral beam with a -3 dB beam width of 117 deg and a ripple width of 2 dB in the sector.
