Claims

[Scope of utility model registration request]

It consists of a radiating plate with many slots, a bottom plate having almost the same shape as the radiating plate, and a side wall plate that interconnects the peripheral edges of the radiating plate and the bottom plate, and has a waveguide space inside. The slot array antenna thus formed includes a feeding section connected to the waveguide space, and the outer periphery of the radiation plate is bonded, crimped, or welded to the upper edge of the side wall plate. A slot array antenna.
