ABSTRACT:
A polarization insensitive lens is disclosed for receiving and reradiating electromagnetic energy, which may be either left-hand circular polarized or right-hand circular polarized or of any linear polarization or, in fact, of any polarization state. Each 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 spaced therefrom by 1/4 wave length. The arms of each antenna element are constructed such that both right-hand circular polarized and left circular polarized signals received by one element experience the same phase delay while being transmitted and then reradiated from the other antenna element.
