  • Patent number: 10587038
    Abstract: Disclosed herein is an implantable electronic device having a housing containing an electrical circuit. The implantable electronic device further includes an antenna assembly coupled to the electrical circuit. The antenna assembly has an antenna with a dielectric antenna body within which an antenna trace is disposed. Portions of the antenna trace are disposed in offset transverse layers in a non-overlapping arrangement, thereby reducing capacitive coupling between the layers of the antenna trace. In certain implementations, the antenna assembly has one or more capacitive features that selectively overlap portions of the antenna trace and facilitate tuning of the antenna.

    Abstract: A dual band antenna mounted to a case of an implantable medical device (IMD) for implant within a patient is provided. The dual band antenna includes a first antenna sub-structure (FAS) and a second antenna sub-structure (SAS) each separately tuned to match a corresponding first and second resonant frequency, by adjusting at least one of relative lengths of the FAS and SAS, a capacitance of the FAS, a location of the SAS relative to the FAS and a cross-sectional area of conducting elements forming the components of the antenna. The FAS is formed as an inverted E-shaped antenna having three branches. The first branch of the antenna is capacitive, a second branch provides a radio frequency signal feed and a third branch provides a shunt to ground. The SAS is formed as a mono-pole antenna that is formed integral with, and extends from, the FAS.

  • Patent number: 9048541
    Abstract: The device includes radio frequency (RF) communication components installed within a case of the device and an antenna with an inverted E shape mounted within a header of the device. The antenna has three branches extending from a main horizontal arm: a capacitive branch connecting one end of the main arm to the case via a capacitive load; an RF signal feed branch connecting a middle portion of the main arm to the internal RF components of the device via a feedthrough; and an inductive branch connecting the opposing (far) end of the main arm to the case to provide a shunt to ground. The E-shaped configuration and the provision of capacitive loading allows for cancellation of inductance to bring the antenna into resonance and to provide optimal radiation efficiency as well as to provide for impedance with no reactive component.
