Hollow waveguide coupling with three axes of movement - has two end flanges bridged by intermediate waveguide sections and telescopic centre section

摘要

The waveguide coupling has 2 relatively spaced hollow waveguide flanges (1a,1b) each of which is formed with a hollow spherical inside face (11a,11b). The flanges (1a,1b) are bridged by 2 intermediate waveguide sections (2a,5a;2b,5b) and a centre waveguide section (4) with telescopic extensions (41a,41b) fitting within end sections (22a,22b) provided by the 2 intermediate waveguide sections (2a,5a;2b,5b). A halfwave choke (31a,32a;31b,32b;23a,23b;51a,51b) is provided between each 2 relatively movable parts. ADVANTAGE - Allows relative sliding, tipping and rotation.
