ABSTRACT:
At least one of the following requirements is satisfied. A position of a curvature center of an arcuate portion in at least one of waveguide plates is selected between a connecting member and a feeder, in accordance with a desired horizontal beam radiation characteristic. A curvature radius of the arcuate portion in at least one of the waveguide plates is selected in accordance with a desired vertical beam radiation characteristic. A slanted angle of a peripheral face of the arcuate portion, which connects a top face and a bottom face of each waveguide plate, in at least one of the waveguide plates is selected in accordance with a desired vertical beam radiation characteristic.
