Abstract
A flat slot array antenna as composed of a waveguide having a rectangular sectional shape, and a power feeder means connected to the waveguide at a power feed opening. A plurality of wave radiation slots are formed within one of the metallic plates forming the waveguide. The length of each slot is progressively increased toward a terminal end of the power propagation within the space of the waveguide within a range which does not exceed the resonance length of the slot, and the distance between the slots is progressively reduced toward the terminal end of the waveguide.
