Abstract

This invention provides a flat circular waveguide device which permits uniform radiation or power through a plurality of power-radiating openings in order to increase the antenna gain in the technical field of electric communications, especially, broadcasting antennas. To achieve such uniform radiation of power, the device is equipped with means for feeding power from a peripheral wall of a wave-guiding space, which is surrounded by metallic walls, toward a central part of the wave-guiding space.
