Title:
ANTENNA ANGLE ADJUSTMENT DEVICE, ANTENNA ANGLE ADJUSTMENT SYSTEM, ANTENNA ANGLE ADJUSTMENT METHOD, AND COMMUNICATIONS DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180609
Kind Code:
A1
Abstract:
[Problem] To provide an antenna angle adjustment device, an antenna angle adjustment system, an antenna angle adjustment method, and a communications device, whereby the angle of an antenna can be adjusted to a direction in which direct waves can be more reliably received. [Solution] An electric field strength calculation unit 21 that calculates electric field strength when an antenna receives direct waves from radio waves radiated by another antenna, on the basis of the distance between the antenna and the other antenna. An electric field strength measurement unit 22 measures the electric field strength of the radio waves received by the antenna that have been radiated by the other antenna. The comparison unit 23 compares the calculation results from the electric field strength calculation unit 21 and the measurement results from the electric field strength measurement unit 22.
