The subject invention provides an improved conformal antenna array assembly having a strip conductor (28), a ground plane (25) separated from and lying parallel to said strip conductor, said ground plane having a slot (27) therein, said slot extending transverse to said strip conductor, a conductive planar element (20) positioned across said slot and orthogonal to said ground plane, said conductive planar element having curved surfaces (22, 23) extending upwardly and outwardly from said slot. The strip conductor or microstrip and the slot-containing ground plane are separated by a dielectric material.
