| Summary: | 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. |
