A wireless communication device includes a first antenna, a second antenna, a first light sensor adjacent to the first antenna, a second light sensor adjacent to the second antenna, a controller, and a magnetic member movably located between the first antenna and the second antenna. When one of the first and second antennas in a state of receiving/transmitting wireless signals is covered by a user's hand, the nearby light sensor sends a pulse signal to the controller. The controller receiving the pulse signal controls the first and second antennas to change their magnetic polarity, enabling the magnetic member to be separated from one of the first and second antennas and attached to the another one, thereby choosing one of the first and second antennas, or a combination of one of the two antennas and the magnetic member to receive/transmit the wireless signals.
