1. A system comprising:
- an implantable antenna configured to wirelessly transfer information electromagnetically at a specified operating frequency, a specific configuration of the implantable antenna configured to operate at the specified operating frequency; and
an implantable dielectric compartment coupled to a single side of an implantable device housing and the implantable dielectric compartment having an outer surface, the outer surface comprising a first side, a second side opposite the first side, and a third side connecting the first and second sides, the implantable dielectric compartment including;
a channel extending along at least a length of the first side, a length of the second side, and a length of the third side of the outer surface of the implantable dielectric compartment, the length of the channel in the third side less than the length of the channel in at least one of the first and second sides;
wherein the channel is configured to provide the specific configuration to an implantable antenna along the length of the implantable antenna.

Abstract
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.
