Embodiments presented herein are generally directed to implantable medical devices that are configured for both near-field communication and far-field communication via the same implantable loop antenna. More specifically, the implantable medical devices include implant electronics that are independently coupled to the loop antenna via a transformer and an isolation coupler. The transformer is configured to provide near-field signals received at the loop antenna to the implant electronics, while the isolation coupler is configured to provide far-field signals received at the loop antenna to the implant electronics.
