A unit cell of an array antenna includes an integrated dilation and feed circuit and an associated radiator assembly. The integrated dilation and feed circuit includes an asymmetric dilation layer, an asymmetric combiner layer, a symmetric feed layer and a symmetric slot layer. Feed circuits on the feed layer are configured to couple radio frequency (RF) signals to/from a pair of orthogonally disposed slot elements symmetrically disposed on the slot layer of the integrated dilation-feed circuit. The slot layer couples signals to and from the radiator assembly. Such unit cell may be used to provide an array antenna including an active electronically scanned array (AESA) antenna.
