Abstract: A method for use with a reflectarray antenna for wireless telecommunication is described. The method involves providing a reflectarray antenna, and adjusting a phase of a scattered field of the reflectarray antenna for generating different radiation patterns for angular mode-based multiplexing. The reflectarray antenna includes a ground plane, a dielectric substrate attached on the ground plane; and a first antenna patch formed on one side of the dielectric substrate. Further, the reflectarray antenna includes a second antenna patch formed adjacent to the first antenna patch with a separation area therebetween; and a phase adjustment member disposed in the separation area. The phase of the scattered field of the antenna is adjusted by changing a DC voltage of the phase adjustment member.
