Title:

ANTENNA DEVICE, COMMUNICATION DEVICE AND COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/147242

Kind Code:

A1

Abstract:

An antenna device 10 is provided with: a reflecting mirror; a primary radiator connected to a wireless device which is provided with a transmitter and a receiver; a radiator support mechanism for rotatably supporting the primary radiator in respect to the center axis of the primary radiator, at the convergence position of the reflecting mirror; an evaluation data acquisition means 101 for acquiring evaluation data, which is data pertaining to a polarization direction angle, which is a tilt angle in respect to the horizontal direction of a polarization plane of the primary radiator, a tilt angle of an own device having a correlation to the polarization direction angle, or detection level; a polarization plane adjustment means 103 for adjusting the polarization plane of the primary radiator on the basis of the evaluation data; and a trigger input means 102 for inputting a trigger to the polarization plane adjustment means 103. The polarization plane adjustment means 103 rotates the primary radiator in accordance with a timing provided by the trigger, and adjusts the polarization plane of the primary radiator.
