DEVICE FOR EXCITATION OF LINEAR EMITTER OF PHASED ANTENNA GRILL WITH W-SHAPED WAVEGUIDE Russian patent published in 1995 - IPC

FIELD: microwave devices. SUBSTANCE: device has piece of W-shaped waveguide, which is connected to coaxial line, which outer wire is connected to bottom of central edge of piece of W-shaped waveguide. Inner wire of coaxial line is connected to starting part of central edge of W- shaped waveguide. Said central edge is designed as bulge over bottom of piece of W-shaped waveguide which has cut in its central edge. Depth of cut equals to λ_m/2, its height and height of face starting part of central edge equal to λ_m/16. Distance between point, where inner wire of coaxial line is connected to starting part of central edge, and start of bulge equals to λ_m/8. λ_m is middle frequency of working band. EFFECT: simplified design. 4 dwg
