PURPOSE:To reduce the coupling between subwaveguides and to decrease the loss, by pvoviding a coupling hole in parallel with a guide axis at a location, 1/2-1/4 of guide wavelength from a tip of a conductor plate distributing power and providing a resistive plate on the same plane as the conductor plate. CONSTITUTION:The conductor plate 4 is provided vertically to an electric field of the basic mode propagating in a main waveguide 1 so as to equally divide the height of the waveguide 1 into two. The coupling hole 6 in parallel with the guide axis is provided at about 1/2-1/4 of guide wavelength from the tip of the conductor plate 4, and the resistive plate 7 is fitted to a part or all of the coupling hole 6. Thus, the electromagnetic waves of the basic mode incident to the waveguide 1 are equally divided into subwaveguides 2 and 3 without being af- fected with the coupling hole 6. The coupling between the waveguides 2 and 3 is decreased. The loss to the basic mode is decreased for the power distribution. |
