Abstract: A phased array antenna device is described. The phased array antenna device includes at least one one-dimensional phased array of radiating elements arranged along an array direction, a lens, and a phase control element. The lens is arranged such that divergent beams from the radiating elements are collimated by the lens in a direction orthogonal to the array direction to produce a beam. The phase control element is configured to apply a linear phase gradient to the radiating elements thereby providing one-dimensional electronic beam steering for the antenna device. The antenna device may additionally include one or two mechanical positioners to mechanically move the at least one one-dimensional phased array in directions orthogonal to the array direction, where the phased array enables scanning along the array direction.
