FLEXIBLE RECTANGULAR WAVEGUIDE Russian patent published in 1997 - IPC

FIELD: microwave engineering. SUBSTANCE: flexible rectangular waveguide is built up of contact-interconnected sections placed along waveguide axis for turning and displacement; they are formed by stiff rectangular waveguide sections inserted one into other, their respective sides being interconnected by means of flexible U-shaped metal strips inserted between internal surface of waveguide section of larger sectional area and external surface of waveguide section of smaller sectional area. One end of each strip contacts section of larger sectional area and other end, section of smaller sectional area. EFFECT: improved performance characteristics of flexible waveguide, such as longitudinal expansion and compression ability, flexibility, reliability, and long life. 3 cl, 4 dwg
