Title:
BEAMFORMER
Document Type and Number:
WIPO Patent Application WO/2024/075238
Kind Code:
A1
Abstract:
The beamformer (10) for directing an incident electromagnetic wave, comprising a first conductive metamaterial cell (11A) configured to shift a phase of a first portion of the electromagnetic wave, a second conductive metamaterial cell (11B) located next to the first conductive metamaterial cell, having a different geometry than the first conductive metamaterial cell, and configured to shift a phase of a second portion of the electromagnetic wave and a conductor (13) including at least a portion disposed between the first conductive metamaterial cell and the second conductive metamaterial cell. According to the above configuration, the disturbance of the capacitance between adjacent metamaterial cells of different geometry (including size) is reduced, thereby reducing sidelobes.
