Abstract

Lumped components are used to represent the reflectarrays designed using different commercially available materials. The loss performance and the effect of material properties on the reflectarray antennas are discussed in terms of the lumped components which are used in the equivalent circuit analysis of the reflectarrays. The bandwidth performance of reflectarrays with different materials is discussed using reflection loss and reflection phase plots obtained by equivalent circuit analysis. The dielectric permittivity (er) of materials investigated in this work ranges between 2.08 to 13 and the loss tangent (tand) values vary from 0.0003 to 0.025.
