Abstract

Techniques for numerical analysis and equivalent circuit modeling for loss performance of reflectarray antennas are presented in this paper. Numerical equations are employed to find out the values of reflection loss at resonant frequency and a novel set of predictions is applied to acquire the reflection loss curve for different materials. Equivalent circuit modeling using lumped components has been developed representing the behavior of reflection loss for reflectarrays designed with different commercially available dielectric materials. The results obtained from both the analysis are found to be in close approximation to the simulated results of reflectarray designs.
