Abstract
A hearing device includes an enclosure comprising a shell and a faceplate and is configured for at least partial insertion within an ear of a user. An antenna structure of the hearing device is oriented such that a direction of an electric field (E-field) of a propagating electromagnetic signal generated by the antenna structure is directed non-tangentially with respect to the user at the location of the user's ear. The antenna structure includes an antenna disposed in or on the faceplate and a ground plane at least partially supported by the faceplate. A battery and electronic circuitry are disposed within the shell. The electronic circuitry is powered by the battery and is electrically coupled to send and/or receive signals via the antenna structure.
