Abstract

This letter presents a new phase-shifting cell topology for dual linearly polarized reflectarrays. It consists of two orthogonal sets of straight slots etched in a metallic plane and loaded with four capacitances in order to control the phase of the reflected wave. Measurements have demonstrated that the convenient capacitive loading of the central slots permits to provide 331 ^° of phase range at 12.5 GHz with linear and parallel dispersions for the different phase states.
