A Wideband Reflectarray Antenna for Millimeter-Wave Applications

In this paper, a waveguide-type reflectarray element is designed and used to form a 16 x 16 reflectarray antenna which generates a pencil beam pointing to the broadside direction. The element consists of a dielectric filled waveguide, and copper wires that reflect the incident waves. The simulation results indicate that the reflectarray antenna can achieve stable high-gain beam from 25 to 35 GHz with low sidelobe level (SLL). The merits of high gain, low profile and wide bandwidth make the proposed reflectarray antenna a promising candidate for millimeter-wave applications and 5G.
