Waveguide, waveguide slot array antenna, and orthogonal dual polarization waveguide slot array antenna

摘要

Problem to be solved: to provide a waveguide in which the divided upper and lower members are fastened by a fastening portion in a tube width direction, and a waveguide for suppressing the deterioration of the reflection characteristic and the passing phase by the fastening portion is obtained.WaveguideProvided with an upper material (1) and a lower material (2) formed into a U shape having a waveguide layer on its inner surfaceA waveguide formed by fitting the upper and lower membersThe upper and lower members areAs it stretches inside the waveguideA fastening part (6) for fitting the upper and lower members is provided.At least one of the upper and lower membersIn the axial direction of the tubeA reduced structure portion (7) for partially reducing the cross-sectional area of the pipe is provided.Diagram
