Lumped components are used to represent the reflect arrays designed using different commercially available materials. The loss performance and the effect of material properties on the reflect array antennas are discussed in terms of the lumped components which are used in the equivalent circuit analysis. The bandwidth performance of reflect arrays designed with different materials is discussed using reflection loss and reflection phase plots obtained by equivalent circuit analysis. Furthermore, the results obtained by equivalent circuit modeling are compared with the results obtained using CST microwave studio simulations and a close agreement between all the results has been demonstrated.
