Title: Corrugated leakage waveguide
Inventor: WATARI TATSU
IPC: H01P3/127
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent radio leakage function from being reduced by forming corrugation in the axial direction of a waveguide and making a long hole to a side face around an apex of a major diameter side of some projections so as to prevent the long hole opening from being clogged against deformation pressure. SOLUTION: The corrugated leakage waveguide 10 has an elliptic cross sectional shape, corrugation is formed in the axial direction and long holes 12 being throughholes are made to a side face around the apex of projections 11 toward the major axis. A pitch Pc of projections 11 of the corrugation has a relation of P/Pc = an integer, where P is a pitch P of the long holes 12. Thus, each long hole 12 is located at the projection 11 at all times. When a pressure is exerted externally to the corrugated leakage waveguide 10 in the direction C, since a major diameter D of each recessed part 13 of the corrugation acts as a fulcrum, one end 12a of the long hole 12 made to the projection 11 is deformed in a direction that the one end 12a is parted from the other end 12b.  Thus, even when a deformation pressure is exerted to the corrugation, the opening of the long hole 12 is not reduced nor clogged and the function of the radio wave leakage is not lost even with more or less deformation.
