Patent ID: 7868829

Claim:
A reflectarray for use in combination with a spaced apart antenna feed element, the reflectarray reflecting energy at first and second different frequencies to and/or from said antenna feed element, the reflectarray comprising: a first array of conductive patches supported by a substrate, wherein each conductive patch in the first array has a first center line along a Y-direction and a second centerline along an X-direction, the conductive patches each having a length dimension and a width dimension, the length dimension being algebraically related to said first frequency and the width dimension being algebraically related to said second frequency for reflecting energy impinging the patches of said first array (i) at said first and second different frequencies and (ii) with different polarizations; a plurality of first variable capacitors, wherein each first variable capacitor is electrically coupled to one of the conductive patches in the first array along the first centerline; and a plurality of second variable capacitors, wherein each second variable capacitor is electrically coupled to one of the conductive patches in the first array along the second centerline.
