Abstract:
A waveguide input apparatus of two substantially orthogonally polarized waves comprising:a waveguide into which a first polarized wave and a second polarized wave respectively having a first plane of polarization and a second plane of polarization substantially orthogonal to each other are introduced, and having one end open and another end closed by a short wall, said waveguide having two cavities passing through an outer wall thereof to its interior,a first probe provided protruding from an inner wall of said waveguide via a first said cavity so that a leading end is substantially parallel to said first plane of polarization,a second probe provided protruding from the inner wall of said waveguide via a second said cavity so that a leading end is substantially parallel to said second plane of polarization, anda circuit board provided at said outer wall to be substantially parallel to said second plane of polarization, and directly connected to said first probe and said second probe.
