PROBLEM TO BE SOLVED: To provide the slot array antenna with uniform performance regardless of a simple configuration with a reduced working time and excellent mass- productivity. SOLUTION: A waveguide wall 13 and a distribution waveguide wall 14 are integrally formed to an inner face of a synthetic resin made radiation slot board 11 to configure a feeding circuit 15 and a distribution guide path 19. Furthermore, the radiation slot board 11 is provided with a plurality of lines of radiation slots 16 along the feeding circuit 15 and a thin radiation groove 17 is formed around them and many fitting projections 18 are provided in an end face such as the waveguide wall 13. Metallic plating processing is applied to an inner face of a microwave guide path formed to the radiation slot boards 11 and a radiation rear board 20 made of a metallic plate is mounted to an opening. A fitting hole 1 is placed to a position corresponding to the fitting projection 18 and the fitting projection 18 is inserted to the fitting hole 21 and tips are projected from the radiation rear board 20 and fastened altogether by a thermal pressure. |
