Title: Integrated reconfigurable polarizer

Abstract: A tunable polarizer having a 90 degree phase shift section and two adjustable, or rotatable, 45 degree phase shift sections. Each section is separated by spacer to maintain independence and avoid interaction. When the two 45 degree phase shift sections and are orthogonal to each other, the polarization detected is determined by the 90 degree phase shift section which provides compatibility with circularly polarized signal. When the two 45 degree phase shift sections and are aligned, the polarizer is in a linear polarization compatibility mode.
