A ROTARY COUPLING FOR A MILLIMETER-WAVE R-F CHANNEL
Abstract
IN THE PROPOSED COUPLING FOR A MILLIMETER-WAVE R-F channel, an H-shaped metal-dielectric waveguide, which is excited under longitudinal-wave conditions, is used. The rotary coupling is accomplished by using the 90-degree cross section of the metal-dielectric waveguide, which is fitted with a metal corner reflector having an aperture, which serves for coupling between the metal-dielectic and circular waveguides. Power is fed to the arm and after reflection strikes the arm, for all practical purposes without loss. In order to increase the coupling between the H-shaped and circular waveguides, an exciting stretcher is placed along the axis of the circular waveguide, just as in the rotary switch used in the ordinary rectangular waveguide. The rotary coupling described is suitable for operation in a narrow waveband. In rder to widen the band of the rotary coupling, it is necessary that the short circuit be located immediately at the cross section. (Author)
