Abstract
A wireless communication device includes a directional antenna that transmits radio signals, and an antenna control unit that measures, in a plurality of directions, spatial lengths from the wireless communication device to an object nearest the wireless communication device, and directs a directional antenna beam radiation direction toward a direction having the longest of the measured spatial lengths, when transmitting the radio signals.

A wireless communication device comprising:
- a directional antenna that transmits radio signals;
- and
- an antenna control unit that measures, in a plurality of directions, spatial lengths from the wireless communication device to an object nearest the wireless communication device, and directs a directional antenna beam radiation direction toward a direction having the longest of the measured spatial lengths, when transmitting the radio signals.
A wireless communication device comprising:
- a directional antenna that transmits radio signals;
- and
- an antenna control unit that, based on respective reflection times of radio waves transmitted from the directional antenna in different beam radiation directions, directs a directional antenna beam radiation direction toward a direction in which a spatial length from the wireless communication device to an object nearest the wireless communication device is the longest, when transmitting radio signals.
A method for controlling a directional antenna of a wireless communication device, the directional antenna transmitting radio signals, the method comprising:
- measuring spatial lengths from the wireless communication device to an object nearest the wireless communication device in a plurality of directions,
- directing a directional antenna beam radiation direction toward a direction having the longest of the measured spatial lengths, when the radio signals are transmitted.
