Abstract
A reflectarray antenna includes a plurality of antenna conductors patterned on two or more planar surfaces. The antenna conductors include a first set of antenna conductors having a geometric arrangement to beamform and radiate a first wireless signal over a first frequency band. A second set of antenna conductors have a geometric arrangement to beamform and radiate a second wireless signal over a second frequency band that is distinct from the first frequency band. The first set of antenna conductors are formed on the two or more planar surfaces to enable operation at the first frequency band. The second set of antenna conductors are formed on the two or more planar surfaces to enable the second frequency band.
