<p>This wireless communications device, etc., is capable of high-precision detection of the direction of a connected wireless communications device and is capable of stable wireless communications. An antenna wirelessly receives data from the connected wireless communications device. A reception control circuit performs a first detection processing that controls the orientation direction of the antenna and detects a first direction being the direction of an electromagnetic wave generation source; and performs a second detection processing that controls the orientation direction of the antenna and detects a second direction being the direction of a connected wireless communications terminal. In addition, the reception control circuit sets the antenna orientation angle smaller when setting the antenna orientation direction in the vicinity of the first direction and performing second detection processing, than when setting the antenna orientation direction not in the vicinity of the first direction and performing second detection processing, and controls the antenna orientation direction so as to suppress the effect of electromagnetic waves from the electromagnetic wave generation source when receiving data when the second direction is in the vicinity of the first direction.</p> |
