Abstract
A waveguide input apparatus of two orthogonally polarized waves includes a waveguide having two cavities passing through the outer wall thereof to the interior, a first probe provided protruding from an inner wall of the waveguide via a first cavity so that the leading end is parallel to a first plane of polarization, a second probe provided protruding from the inner wall of the waveguide via a second cavity so that the leading end is parallel to a second plane of polarization, and a circuit board provided at the outer wall of the waveguide so as to be parallel to the second plane of polarization, and having the first probe and the second probe connected thereto. A converter for satellite broadcasting receiver employing this apparatus is also provided.
