Abstract
A reflectarray antenna for achieving increased dynamic phase range has a plurality of dipole elements positioned across the antenna surface. The elements include a single dipole element having a predetermined length that is approximately proportional to the dynamic phase range through which the first dipole element can reflect. The elements also include a coupled dipole element which comprises a longer dipole and a shorter dipole. The longer dipole and the shorter dipole are positioned on the reflectarray surface such that they are spaced a predetermined distance apart.
