An antenna element (20) comprising a first conductive plane (22), a second conductive plane (24), and one or more dielectric layers (26, 28, 30) separating the first and second conductive planes (22 and 24). A resonant cavity (48) is formed by a portion of the first conductive plane (22), a portion of the second conductive plane (24) and electrical connections (e.g., plated vias(40)) extending therebetween. A slot (32) is formed in the portion of the second conductive plane (24) forming one side of the resonant cavity (48) and the feedline (34) extends into the cavity (48).
