Abstract

Reflective arrays based on shorted ring slots are analyzed. It is proven that reflection angle for the normally incident circularly polarized wave can be effectively changed by proper situation of the conductive shorts. Thus, phased arrays with wide-angle scanning can be built using arrays of shorted ring slots.
