Patent attributes
A hearing aid including a hearing aid antenna assembly, a transceiver, and an acoustic transducer is provided. The hearing aid assembly includes a resonant loop antenna, a coupling mechanism such as a primary loop, and an electrically conductive assembly. The resonant loop antenna forms an aperture that is arranged to be substantially parallel to a head of the wearer when the hearing aid is worn. The coupling mechanism is configured to transfer RF energy between the transceiver and the resonant loop antenna. The resonant loop antenna excites the electrically conductive assembly. The electrically conductive assembly includes a battery shield. The resonant loop antenna, the coupling mechanism, and/or the electrically conductive assembly are formed in one or more conductive layers of FPCB. The resonant loop antenna includes a course tuning capacitor in series with a fine tuning capacitor. The primary loop includes a resonating capacitor.
