To provide an electronic apparatus capable of easily recognizing the other party while reducing the number of array antennas being used, in view of the circumstances in which the direction (range) in which communications can be performed, which is restricted in communication waves with high objectivity, can be expanded by providing a plurality of array antennas, for example, but increase of the number of array antennas being used causes problems such as increase in manufacturing cost and increase in power consumption.
An electronic apparatus according to an embodiment comprises an antenna portion capable of transmitting and receiving communication waves in a first direction. The electronic apparatus further comprises a switching portion provided in a part of the first direction and capable of electrically switching the direction in which the communication waves can be transmitted and performed to a second direction.
