1. An external component of an implantable medical device system, comprising:
a multi-band antenna arrangement;
an electronics circuit;
a coil driver coupled between the multi-band antenna arrangement and the electronics circuit and configured to at least one of send and receive, via the multi-band antenna arrangement, near-field signals from an implantable component inductively coupled to the multi-band antenna arrangement; and
an isolation circuit coupled between the multi-band antenna arrangement and the electronics circuit and configured to at least one of send and receive, via the multi-band antenna arrangement, far-field signals from at least one external and to provide the far-field signals to the electronics circuit.
