WIRELESS COMMUNICATION DEVICE AND MOBILE TERMINAL

摘要

A wireless communication device that communicates wirelessly with other device includes a first antenna, a second antenna, a measurer, and a selector. The first antenna is a loop or loops of coiled wire, and the first antenna is disposed on a substrate so that a rotation axis of the first antenna is orthogonal to the substrate. The second antenna is a loop or loops of coiled wire, and the second antenna is disposed on the substrate so that a rotation axis of the second antenna is parallel to the substrate. The measurer measures signals respectively generated in the first antenna and the second antenna, in accordance with a positional relationship between the other device and the wireless communication device. The selector selects one of the first antenna and the second antenna as an antenna for communicating with the other device, in accordance with amplitude of the measured signals.
