1. An antenna for use with a medical implant, the antenna comprising:
- an inductor assembly including at least two conductors, which each define a conductor diameter DC, and an electrically non-conductive carrier defining at least two lumens in which the at least two conductors are respectively located that maintains a conductor spacing S between the at least two conductors;
wherein the inductor assembly defines at least one turn; and
wherein the conductor spacing S and conductor diameter DC together define a S/DC ratio that ranges from about 0.5 to about 1.2.

Abstract
An antenna having an inductor assembly including at least two conductors, which each define a conductor diameter Dc, and an electrically non-conductive carrier defining at least two lumens in which the at least two conductors are respectively located. The carrier maintains a conductor spacing S between the at least two conductors, and the inductor assembly defines at least one turn. The conductor spacing S and conductor diameter Dc together define a S/Dc ratio that ranges from about 0.5 to about 1.2.
