Abstract
A system and method provide simultaneous dual polarization operation using a linearly-polarized planar antenna and a polarizer spaced apart from the linearly-polarized planar antenna, the polarizer including a first polarization state having primarily one of left-hand circular polarization (LHCP) or right-hand circular polarization (RHCP), and a third polarization state having linear polarization from which a combination of both LHCP and RHCP is simultaneously derived. The polarizer is placed in the first polarization state to at least one of transmit or receive a signal having primarily one of LHCP or RHCP, and the polarizer is placed in the third polarization state to simultaneously transmit and/or receive two different signals, where a first signal of the two different signals has primarily LHCP and a second signal of the two different signals has primarily RHCP.
