Reflectarray antenna constructed by arranging double omega-shaped resonant elements with mirror image for circular-polarization conversion

This paper proposes novel reflectarray elements by arranging double omega-shaped resonant strips with mirror image for converting a linearly polarized incident wave into a circularly polarized radiated wave. As a design example, a linear-to-circular polarizer reflectarray is presented and also its polarization property of far-field patterns over 12-17 GHz is discussed numerically and experimentally.
