Title:
PHASE CONTROL DEVICE, ANTENNA SYSTEM, AND METHOD OF CONTROLLING PHASE OF ELECTROMAGNETIC WAVE
Document Type and Number:
WIPO Patent Application WO/2020/148809
Kind Code:
A1
Abstract:
An object is to actively control a phase of electromagnetic wave with high efficiency. A phase control device (100) includes a phase control lens (10) and a control circuit (20). The phase control lens (10) includes metamaterial boards (11, 12) arranged in the Z-axis direction and separated from each other. Each metamaterial board shifts a phase of electromagnetic wave passing therethrough. The control circuit (20) controls admittance distribution in a plane perpendicular to the Z-axis direction of each metamaterial board.
