Abstract
A microwave antenna is made of a pair of parallel ground-plane conductors (12 and 14), one of which forms a generally cruciform aperture (18). A pair of T-shaped feedlines are disposed with their cross pieces (22 and 34) in registration with the respective arms (20 and 36) of the aperture 18 and are independently driven from stems (26 and 32) disposed between the ground-plane conductors.
