摘要： A wireless communication apparatus includes a transmitting antenna; and a receiving antenna that receives a wireless signal transmitted from the transmitting antenna. Each of the transmitting antenna and the receiving antenna includes a plurality of circular loop antennas arranged concentrically in an identical plane, each of the plurality of circular loop antennas having a loop perimeter approximately equal to an integer multiple of one wavelength determined from a frequency in a wireless communication; and a plurality of feeding sections individually connected with the plurality of circular loop antennas. A central axis of the plurality of circular loop antennas of the transmitting antenna and a central axis of the plurality of circular loop antennas of the receiving antenna are arranged approximately on a straight line. Thus, a wireless signal is transmitted between the circular loop antennas having a loop perimeter of a transmitting side and a receiving side.
