Comparison of Synthesis Strategies for a Dual-Polarized Reflectarray

[摘要] This paper presents and compares four optimizationstrategies for printed reflectarrays. They are applied to synthesizea dual-polarized reflectarray using two kinds of slot-loadedpatches. They provide objective criteria to deal with the numerousgeometrical parameters available to tune the phase. Thestudy relies on the comparative measurements of four differentprototypes for the same22λ0×22λ0reflectarray (withλ0thewavelength atf0=14.25 GHz).
