An equivalent unit cell waveguide approach (WGA) is described to study the behavior of a multilayer reflect array of variable‐size patches/dipoles. The approach considers normal incidence of a plane wave on an infinite periodic array of identical radiating elements and introduces an equivalent unit cell waveguide to obtain the reflection coefficient. A field matching technique and method of moments (MoM) is used to determine fields in different layers of the equivalent waveguide. Good agreements for the phase of the reflection coefficient between the proposed model and those published in selected literatures are obtained. © 2002 Wiley Periodicals, Inc.
