A device (502) includes a multi-loop antenna (516) with at least two magnetic loop antennas (602, 604) electrically connected in parallel. The at least two magnetic loop antennas each are configured to transmit and receive signals over predetermined frequency bands. The device further includes a single feed line (524) configured to drive both of the at least two magnetic loop antennas and a wireless communication component (510) configured to drive the single feed line. A method includes receiving a first activation signal for a first magnetic loop antenna of at least two magnetic loop antennas electrically connected in parallel, feeding the first magnetic loop antenna with a feed line, receiving a second activation signal for a second magnetic loop antenna of the at least two magnetic loop antennas electrically connected in parallel, and feeding the second magnetic loop antenna with the same feed line.
