  • Impedance-controlled implantable telemetry antenna
    Patent number: 8195305
    Abstract: A physical arrangement can be provided between at least a portion of a first segment of an implantable antenna with respect to a return conductor, and an input impedance of the implantable antenna can be controlled using the physical arrangement to provide a substantially conjugate match to an output impedance of an implantable telemetry circuit coupled to the implantable antenna.
    Type: Grant

  • MULTI-BAND ANTENNA FOR IMPLANTABLE DEVICE
    Publication number: 20110082523
    Abstract: This document discusses, among other things, a system and method for wirelessly sending information electromagnetically at one of a first or a second specified operating frequency from within a biological medium, or receiving information electromagnetically at one of the first or second specified operating frequencies in the biological medium, using an implantable antenna including a switchback portion having multiple segments. The first specified operating frequency and the second specified operating frequency can be provided using the multiple segments.
