Document Type and Number:
WIPO Patent Application WO/2017/029777
Kind Code:
A1
Abstract:
An antenna apparatus (10) is provided with a plurality of antennas (11, 12) each including a matching circuit (11b, 12b), a control circuit (15) for controlling the matching circuit of each antenna and thereby adjusting the impedance of each antenna, and a wireless circuit (13) for processing the signals transmitted and received by each antenna. The control circuit selects one of the plurality of antennas, controls the matching circuit of the selected antenna to match the selected antenna and the wireless circuit, and controls the matching circuits of the unselected antennas so that the unselected antennas and the wireless circuit do not match. The control circuit controls the wireless circuit so as to output a signal to the selected antenna during signal transmission, and controls the wireless circuit so as to receive the signal from the selected antenna during signal reception.
