NON-CONTACT ANTENNA FEED

摘要

The present disclosure relates to inclusion of a non-contact antenna. The non-contact antenna can allow a variety of antennas to be used on a hearing assistance device and can overcome issues associated with mounting an antenna internal to the case of a hearing assistance device. A non-contact antenna may include a proximity coupled antenna, such as an antenna mounted on a hearing assistance device case (external to the case) near a feed line that will transfer energy between the antenna and an SMD internal to the case. A non-contact antenna may include an aperture coupled antenna, such as an antenna mounted external to the case on an antenna substrate, where the antenna substrate is on a feed substrate with a feed line, and where there is an aperture in a ground plane.

主权项

1. A hearing assistance device comprising:
a housing including processing circuitry therein; a feed line electrically connected to the processing circuitry, the feed line including a first portion internal to the case and second portion external to the case; a dielectric material; and an antenna mounted on an exterior of the case in proximity to the second portion of the feed line so as to be separated from the feed line by a dielectric material and electromagnetically coupled with the feed line.
