Classification: CPC H | IPC H

Claim 0:
1. A device, comprising:
a selection circuit; and
an antenna, comprising:
a substrate;
a first conductive trace on the substrate forming a first coil comprising a first number of turns and spaced apart first and second coil ends, wherein the first coil is capable of generating a first inductance, and wherein adjacent turns within the first coil are separated by a first gap width;
a second conductive trace on the substrate forming a second coil comprising a second number of turns and spaced apart third and fourth coil ends, wherein the second coil is electrically connected to the first coil and is capable of generating a second inductance, wherein adjacent turns within the second coil are separated by a second gap width, and wherein the first and second coils are separated by a third gap width that is different than at least one of the first gap width or the second gap width; and
first, second, and third terminals that are electrically connectable to the selection circuit, wherein (i) the first terminal is electrically connected to the first coil end of the first coil, (ii) the second terminal is electrically connected to the fourth coil end of the second coil, and (iii) the third terminal is electrically connected to a junction point that is between the second coil end of the first coil and the third coil end of the second coil; and
wherein the selection circuit is configured to select a given one of multiple possible pairwise combinations of the first, second, and third terminals and thereby causes the antenna to operate in a given one of multiple operating modes in which the antenna generates a given inductance value.
