摘要：A slotted waveguide antenna comprises a plurality of radiating waveguides (38-1, 38-2,...) having at least one radiating slot (40), a feed waveguide (36) for feeding to theradiating waveguides (38-1, 38-2,...), and coupling apertures arranged between the feedwaveguide (36) and the radiating waveguides (38-1, 38-2,...) at a distance of an integermultiple of teh guide wavelength (λg) of the feed waveguide (36). The plurality ofradiating waveguides (38-1, 38-2,...) are disposed in parallel to form an array in a mannerthat the radiating slots (40) in the respective radiating waveguides (38-1, 38-2,...) aredirected in the same direction. The feed waveguide (36) is on the same plane as the arrayformed by the radiating waveguides (38-1, 38-2,...). The transverse width of each radiatingwaveguide is one half of the distance between the adjacent coupling apertures (46-1, 46-2,...). The coupling apertures (46-1, 46-2,...) provided on the feed waveguide (36) supplyelectromagnetic waves having the same amplitude and the same phase to each radiatingwaveguide (38-1, 38-2,...). The feed waveguide (36) and the radiating waveguides (38-1, 38-2,...) are arranged integrally on the same plane so that the overall structure is planar. Thestructure of the antenna is simple, so that the antenna is manufactured easily andinexpensively.
