Single-Layer Reflectarray Cell Synthesis Based on Filter Synthesis Techniques
Résumé
This paper presents a method for synthesizing the equivalent circuit of a single-layer reflectarray unit-cell based on filter synthesis techniques. Metallic-ring and slot-ring cells are synthesized respectively by 3 rd-order band-stop and band-pass Tchebycheff filters. A phase range of 360 at 12.5 GHz is achieved with an maximum average phase error of 16 for a phase dispersion of 60 /GHz in the band of interest 10.5-14.5 GHz.
