LEAKY WAVEGUIDE

WIPO Patent Application WO/2020/149407

A1

A leaky waveguide is configured by forming metal tubes for propagating electromagnetic waves in such a manner that a cross-section thereof is a flat-circular shape and the metal tubes each have a first opening and a second opening with the distance between the centers of these openings being longer than a half-wave length. The plurality of first openings and second openings are mutually parallel. The plurality of first openings are positioned such that a line connecting the centers thereof is parallel to the axial direction of the metal tubes. The distance between the centers of adjacent ones of the plurality of first openings positioned such that the line connecting the centers thereof is parallel to the axial direction of the metal tubes is approximately equal to the wavelength of the electromagnetic waves. The plurality of second openings are positioned such that a line connecting the centers thereof is parallel to the axial direction of the metal tubes. The distance between the centers of adjacent ones of the plurality of second openings positioned such that the line connecting the centers thereof is parallel to the axial direction of the metal tubes is approximately equal to the wavelength of the electromagnetic waves.
