A FREQUENCY SELECTIVE POLARIZER

摘要

A wideband frequency selective polarizer is provided. The wideband frequency selective polarizer includes arrays of first-frequency slots in at least two metallic sheets in at least two respective planes; and arrays of second-frequency slots interspersed with the arrays of first-frequency slots in the at least two metallic sheets in at least two respective planes. A polarization of a first-frequency radio frequency (RF) signal in a linearly-polarized-broadband-RF signal that propagates through the at least two planes is one of: rotated by a first angle in a negative direction; or un-rotated. A polarization of a second-frequency-RF signal in the linearly-polarized-broadband-RF signal is rotated by a second angle in a positive direction.
