Title:
WIRELESS COMMUNICATION DEVICE AND COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/065054
Kind Code:
A1
Abstract:
A wireless communication device (10) is provided with: an array antenna (20) composed of a plurality of antenna elements (21a-21d); and a communication circuit (50) that carries out wireless communication by performing switching between a first mode and a second mode with use of the array antenna (20). Transmission power in the wireless communication during the first mode is greater than that during the second mode, and the communication speed during the first mode is higher than that during the second mode. During the second mode, the communication circuit (50) weights the amplitude of a signal for exciting at least two of the antennal elements (21a-21d), thereby carrying out the wireless communication with a directivity of the array antenna (20) wider than that during the first mode.
