Abstract

PURPOSE:To reduce the side lobe level to a usable degree, by mounting a pair of parallel dielectric plates on the channel-shaped metallic wall face plate provided in the slot waveguide. CONSTITUTION:Part 2 where the side face section consisting of a metallic wall face plate is channel-shaped has slot waveguide 1' mounted in the vertical side and functions to lead radiated electric power from waveguide 1' to one direction. Dielectric plate 3' consists of a pair of dielectric plates having <=1/20thickness of the use wavelength along two parallel sides of part 2' and is protruded and extended to the channel-shaped aperture direction and converges radiated electric power in this direction furthermore. Metallic splints 4 are provided as a pair of plates opening vertically from the aperture edge of part 2'. Electromagnetic waves are incident at a lower angle according as distance (d) between dielectric plates is shorter (<=0.5lambda), and the end fire characteristic is increased to reduce the side lobe. Electromagnetic waves incident onto plate 3' are reflected by splint 4, and the radiation pattern is corrected to reduce the side lobe.
