Abstract

PURPOSE:To obtain coupling characteristics extending over a wide band, by providing a waveguide and a mismatching coupling waveguide member on the coupling part. CONSTITUTION:A waveguide 1 and a microstrip line 5 are connected through a coupling waveguide 21 whose guide dimensions (a'), (b') are larger by the necessary quantity than guide dimensions (a), (b) of a waveguide 11. In this state, mismatching is generated on the contact surface of the waveguide 11 and a coupling guide part 22, a microwave transmitted from the direction as indicated with an arrow A of the guide axis of the waveguide 11 is coupling-converted to the line 5 by an operation of a short place 31, and is transmitted in the direction as indicated with an arrow A'. Also, a distance (l) to an optimum short plate is selected in accordance with relational dimensions of the projecting quantity (m) of an electric conductor 52 in the strip and the distance l1 to a flange end 13 of the waveguide 1, the impedance is matched with a prescribed frequency, and the coupling characteristics extending over a wide band is obtained.
