Abstract

PURPOSE:To reduce the number of components and to reduce the cost, by laminating and fixing a power feeding waveguide without using a bent or a flange. CONSTITUTION:At the rear side of an antenna opening 1 having a slot array 10, a power feeding section consisting of power feeding waveguides 12-14, a waveguide block 29 and a waveguide joint 11 is formed. The waveguides 12-14 insert and fix a comb-shaped electromagnetic wave reflector 16 corresponding to a waveguide bent to a required number of waveguide elements 15 for both ends and a waveguide joint 11 is processed to each waveguide element tube 15. The waveguide block 20 is processed with waveguide holes for a required number to a plate and the thickness is equal to that of the waveguide 13. The waveguides 12-14 and the block 20 are piled up to the antenna opening 1 while matching the joint 11 to constitute a power feeding waveguide group 2 of an array antenna.
