ABSTRACT:
A polarization twister for twisting the polarization of a wide angle incident electromagnetic wave is described. Specifically, the polarization twister includes a reflector for reflecting the wide angle incident electromagnetic wave, a dielectric substrate having a longitudinal axis, a spacer bonded on a first side thereof to the dielectric substrate and on a second side thereof to the reflector, and an array of meanderline conductive strips etched on the dielectric substrate. Each meanderline conductive strip has an axis extending at a 45.degree. angle with respect to the longitudinal axis of the dielectric substrate. In operation, the meanderline conductive strips serve to advance the phase of a parallel component of an incident E-field vector, and delay the phase of the perpendicular component thereof. Accordingly, the reflected field has its polarization twisted 90.degree. from the incident polarization.
