Multibeam 2D Lens Antenna Based on Metasurface Technology

A multibeam antenna (MBA) is defined as an antenna with the ability to generate simultaneously multiple independent beams from a single aperture and has an important role in wireless communication and radar systems. Multibeam antenna systems operating in the millimeter-wave frequency, have attracted a lot of research and have been actively investigated for fifth generation (5G) wireless communications applications. This paper describes the design process of a multibeam 2D lens antenna inspired by the Rotman lens design concept and based on a multilayer metasurface printed elements structure. The goal of this research is to design an MBA using a lens with printed elements to obtain a high gain and low side lobes in radiation pattern.
