<p>An antenna array that uses at least two passive antennas (110, 112) and one active antenna (120) disposed above a ground plane (140), but electrically isolated from the ground plane, and a respective resonant strip (1216) positioned beneath each passive antenna. The passive antenna elements are positioned about the active element, and each of the at least two passive antenna elements is individually set to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus.</p> |
