Description:
<jats:p>This paper presents and compares four optimization strategies for printed reflectarrays. They are applied to synthesize a dual-polarized reflectarray using two kinds of slot-loaded patches. They provide objective criteria to deal with the numerous geometrical parameters available to tune the phase. The study relies on the comparative measurements of four different prototypes for the same reflectarray (with the wavelength at GHz).</jats:p>
