ABSTRACT:
A waveguide according to this invention has a waveguide portion used in transmission in a relatively low frequency band, and a stub circuit portion, connected in series with the waveguide portion, for achieving impedance matching. Since the waveguide for the relative low frequency band, i.e., a frequency band equal to or lower than 40 GHz, has a large aperture size, it has a sufficient mechanical strength even in a use in a satellite. When the stub circuit portion is connected in series with the waveguide, the impedance of the waveguide can be improved, and sufficient transmission performance can be attained even in a millimeter wave frequency band equal to or higher than 40 GHz.
