Design of a metasurface Luneburg lens antenna with flared structure

Abstract

This article demonstrates the design of a meta-surface Luneburg lens antenna with flared structure. The lens antenna is composed of two flared metallic cones, a metasurface Luneburg lens and a reflection plate. The refraction index of Luneburg lens can be obtained by gradually changing the radius of patch arraying on the substrate. Such an antenna structure… (More)
