Abstract
Provided is a resonant multi-loop antenna circuit for magnetic field communication. The resonant multi-loop antenna circuit includes a first loop antenna and a second loop antenna arranged substantially on a same plane, and a first/a second matching circuit connected in series to the first and the second loop antenna respectively. The first matching circuit may be configured to minimize reactance of the first loop antenna and the first matching circuit connected in series to each other at a first carrier frequency, the second matching circuit may be configured to minimize the reactance of the second loop antenna and the second matching circuit connected in series to each other at a second carrier frequency, and the first loop antenna and the second loop antenna may be arranged so that a center of the first loop antenna is spaced apart from a center of the second loop antenna by a predetermined distance.
