TRANSMISSION LINE ANALYSIS OF APERTURE-COUPLED REFLECTARRAYS [PDF]
Progress In Electromagnetics Research C, 2008 A fast analysis of aperture-coupled reflectarrays is presented in this work in terms of transmission line model. The circuital approach is adopted to derive the phase design curve as a function of the current flowing on the equivalent impedance of the single radiating element.
