Abstract

The analysis of scattering from an infinite periodic array of microstrip patches is employed for the numerical study of a line-source-fed, single-layer microstrip reflectarray. By utilising rectangular patch geometries in the modelling, reflection phase properties of the reflectarray are rigorously examined. Important parameters such as patch length, substrate permittivity and thickness are investigated. Also included is the effect of unattainable reflection phase on phase corrections and radiation characteristics
