Abstract
A slot array antenna is composed of a rectangular waveguide formed by means of oppositely disposed plates and side plates, and a power feeder means connected to the rectangular waveguide at a power feed opening. A plurality of wave radiation slots are formed within one of the plates. The power feeder means is arranged such that two powers fed therein are changed into two plane waves, at the power feed opening, having two independent dominant modes. The slots comprise longitudinal slots extending in a longitudinal direction of the waveguide and lateral slots extending in a lateral direction of the waveguide so as to radiate two plates waves respectively.
