1. A hearing assistance device, comprising:
- an enclosure that includes a faceplate and a shell attached to the faceplate;
a power source;
a flex antenna having a shape of at least a substantially complete loop around the power source, wherein the flex antenna maintains separation from the power source and wherein the flex antenna has at least a portion including a shape memory that tends to straighten the flex antenna from a flexed position, and bias a portion of the flex antenna into contact with an interior surface of the enclosure;
a transmission line connected to the flex antenna; and
radio circuit connected to the transmission line and electrically connected to the power source.
