ABSTRACT:
A polarization controllable lens is disclosed for receiving and re-radiating linearly polarized electromagnetic energy. The lens is comprised of a pair of spaced apart multiarm/antenna elements of opposite geometric polarization. The elements are located on opposite sides of a ground plane and are spaced therefrom by 1/4 wave length. The arms of the two antenna elements are constructed of different lengths such that the right-hand circular polarized and left-hand circular polarized components of a linearly polarized signal experience different phase delays while being received and then re-radiated. As a result, the linear polarization state of the re-radiated energy is rotated by an amount proportional to such difference in lengths.
