Abstract
An apparatus for compensating for distortions in RF beams caused by a radome. The apparatus comprises: i) a plurality of metal patches arranged in rows and columns; ii) a first plurality of varactors coupling adjoining ones of a first plurality of metal patches in a first row of metal patches; and iii) a first reference voltage source configured to apply a first reference voltage to the first plurality of metal patches in the first row. The apparatus further comprises: iv) a second plurality of varactors coupling adjoining ones of a second plurality of metal patches in a first column of metal patches; and v) a second reference voltage source configured to apply a second reference voltage to the second plurality of metal patches in the first column. The first and second reference voltage sources adjust the phase delays of RF beams passing through each metal patch in the rows and columns.
