An antenna array includes a dielectric substrate comprising an integral center hub including a pivotal center section therein, and a pivotal wings extending radially from the integral center hub. An active antenna element is on the pivotal center section of the integral center hub, and passive antenna elements are on the pivotal wings. The active antenna element and the passive antenna elements are pivotal between a stored position and an operational position. The active antenna element and the passive antenna elements are substantially planar when in the stored position, and are substantially perpendicular to the integral center hub when in the operational position.
