Method for use with a reflectarray antenna for wireless telecommunication
First Claim
1. A reflectarray antenna for wireless telecommunication, comprising:
- a ground plane;
a dielectric substrate attached on the ground plane;
a first antenna patch formed on one side of the dielectric substrate;
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, wherein each of the first antenna patch and the second antenna patch is connected only to the phase adjustment member, and configured to adjust a phase of a scattered field of the reflectarray antenna in accordance with a DC voltage applied to the reflectarray antenna such that different angular mode radiation patterns are generated for transmitting and receiving signals by multiplexing and demultiplexing.

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.
