BEAM TILT ANGLE CONTROL DEVICE, ANTENNA SYSTEM, WIRELESS COMMUNICATION DEVICE, AND BEAM TILT ANGLE CONTROL METHOD

摘要

A beam tilt angle control device (1) of the present invention is provided with at least a dielectric plate (11), and a dielectric plate (12) that is disposed such that at least a part thereof overlaps the dielectric plate (11) in the thickness direction. A beam tilt angle control device (1) of the present invention is configured such that the tilt angle of a beam propagating in the thickness direction of the dielectric plates (11, 12) is controlled by changing the area where the dielectric plates (11, 12) overlap each other in the thickness direction of the dielectric plates (11, 12).
