Abstract
PURPOSE:To effectively utilize a feeding power, by performing feed to the space of a square waveguide by a horn type waveguide via a parabolic mirror, and forming the equiphase plane of an electric field in the space of the square waveguide in flat shape. CONSTITUTION:The parabolic mirror which forms a corner part C to reflect the feeding power is inserted at a feeding path from the horn type waveguide 4a to the space S of the square waveguide so as to form the equiphase plane of the electric field in the space S of the square waveguide in the flat shape. And by supplying the power from the horn type waveguide 4a to the space S of the square waveguide via a power supplying aperture, a phase difference is compensated by the parabolic mirror, and the power with almost equiphase can be radiated via a power radiating slot 1a. In such a way, it is possible to perform the feed effectively.
