Summary:A flat slot array antenna is composed by a waveguide having a rectangular sectional shape, and a power feeder means 4 connected to the waveguide at a power feed opening 3a. A plurality of wave radiation slots 1a are formed in one of metallic plates 1 forming the waveguide. The length of the slot is progressively increased toward a terminal end of power propagation in the space of the waveguide in a range without exceeding a resonance length of the slot, and the distance between the slots is progressively reduced toward the terminal end.
