This document discusses, among other things, an implantable dielectric compartment including a channel in an outer surface of the implantable dielectric compartment, the channel configured to constrain a portion of an implantable antenna in a specific configuration along the length of the portion of the implantable antenna. In certain examples, the implantable antenna can be configured to wirelessly transfer information electromagnetically at a specified operating frequency provided using the specific configuration of the portion of the implantable antenna.

In-header perimeter RF antenna

An apparatus includes an implantable housing, a header including a cavity, a post extending from a surface of the housing into the cavity, the post including an expanded head portion, and a retaining member mounted within the header and engaged with the post with a bottom surface of the retaining member abutting an internal surface of the header.

Apparatus and method for attaching a header to a housing of an implantable device

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.
