Abstract

Multi-layer mushroom reflectarray with parasitic layers can control capacitance value theoretically using parasitic layers number. This paper studies the frequency characteristics of the Multi-layer mushroom reflectarray with parasitic patches using LC resonant circuit theory. To use the reflectarray for propagation improvement, this paper investigate reflection angle for oblique incidence using reflectarray design theory and measurements in chamber. The results show compared with LC resonant theory, FEM simulation and measurements.
