ABSTRACT:
A dual band circular polarizer for simultaneously transforming two to four linearly polarized waves of two different frequency bands into two to four circularly polarized waves, and vice versa, the polarizer comprising a waveguide of circular or square cross-sectional shape dimensioned to simultaneously propagate signals in two different frequency bands and two arrays of conductive elements, each array comprising a pair of diametrically opposed rows of conductive elements extending inwardly from the walls of the waveguide.
