An antenna includes a lower plate assembly having at least one antenna port and including a beamformer which provides a uniform excitation on the first surface of the lower plate assembly in response to a signal fed to the at least one antenna port and an upper plate having a radiating aperture, the upper plate movably disposed on the first surface of the lower plate assembly to couple energy from the beamformer in the lower plate assembly to a plurality of radiating elements, wherein the position of the upper plate relative to the lower plate determines a scan angle of the antenna. |
