Abstract

1305002 Dielectric waveguide systems MOSKOVSKY ORDENA LENINA ENERGERTICHESKY INSTITUT 15 April 1971 9455/71 Heading H1W An all-dielectric waveguide is of rectangular cross-section and is held in position at terminal and intermediate locations by clamps bearing on the minor faces. At the intermediate stations (Figs. 2, 4), the waveguide 1 is clamped between the fixed, lower jaw 13 and movable, upper jaw 11 of a clamp 7. A stanchion may be screw threaded to the lower part of the clamp. Flared conductive plates 5 extend through the clamp on either side of the waveguide and serve to confine the electromagnetic field in the vicinity of the clamp. At a terminal location (Figs. 5, 6, 7), the dielectric waveguide 1 is matched to a hollow, rectangular waveguide 4. Between sections D and E, the major dimension of the hollow waveguide 4 is increased to the width of the flared plates 5<SP>1</SP> which are similar to plates 5, Fig. 2. At section E, the narrow walls of the waveguide 4 terminate, and the wide walls diverge to the full width of the dielectric waveguide. At section F, the wide walls of the hollow waveguide 4 merge with the plates 5<SP>1</SP>. The clamp 7<SP>1</SP> comprises a rectangular annular member 16 and two clamping screws 17, 18.
