WIRELESS COMMUNICATION APPARATUS AND ANTENNA DEVICE

WIPO Patent Application WO/2018/216438

A1

A transmitting antenna 100 and a receiving antenna 200 are each provided with: a first circular loop antenna group 100A, 200A in which respective circular loop antenna elements have different perimeters each being approximately an integral multiple of a wavelength determined from a wireless communication frequency, and are concentrically disposed on the same plane; and a second circular loop antenna group 100B, 200B which has circular loop antenna elements having the same perimeters as those of the plurality of circular loop antenna elements of the first circular loop antenna group. Between the first circular loop antenna group and the second circular loop antenna group, the angular position of a terminal connecting a power supply unit to the circular loop antenna element of the same perimeter is set to an angular position rotated by (2l+1)π/2mi (where l is an arbitrarily defined integer, mi is the value of m1-mN that is approximately an integral multiple of a wavelength).
