An array antenna has rectangular conductor sections, located successively side by side in a first plane, mutually separated by slots of constant width. A backing reflector is transverse to the first plane. Feed structures extend through the backing reflector, the feed structures comprising pairs of parallel feed conductors, each pair comprising conductors coupled to the rectangular conductor sections on opposite sides of a respective one of the slots.
