1. A medical device, comprising:

  • a flexible carrier configured to be implanted in a body of a subject;

    at least one electrode disposed on the flexible carrier, the at least one electrode being configured to modulate nerve fibers of the subject;

    a flexible antenna disposed on the flexible carrier, the flexible antenna electrically connected to the at least one electrode in a manner permitting at least some energy received by the flexible antenna to be transferred to the at least one electrode, the flexible antenna including;

    at least a first conductive trace arranged on a first side of the flexible carrier, the at least a first conductive trace defining at least a first elongated space between portions thereof; and

    at least a second conductive trace arranged on a second side of the flexible carrier, the at least a second conductive trace defining at least a second elongated space between portions thereof,wherein the at least a first conductive trace is at least partially offset from the at least a second conductive trace such that portions of the first conductive trace overly the at least a second elongated space and wherein portions of the second conductive trace underlay the at least a first elongated space,wherein the first conductive trace includes first windings and at least some of the first windings are connected to one another by first electrical trace steps, the second conductive trace includes second windings and at least some of the second windings are connected to one another by second electrical trace steps, and one or more of the first electrical trace steps cross one or more of the second trace steps at a non-zero angle.
