Patent ID: 8538051

Claim:
A mobile wireless communications device for a user wearing an electronic hearing aid adjacent an ear of the user, the mobile wireless communications device comprising: an upper housing and a lower housing being coupled for sliding relative to one another between a retracted position and an extended use position, said upper and lower housings each having respective top and bottom ends, the top end of said upper housing being further separated from the bottom end of said lower housing when in the extended use position as compared to the retracted position; an audio output transducer carried by the top end of said upper housing and accessible to the electronic hearing aid of the user; an audio input transducer carried by the bottom end of said lower housing; and a multi-frequency band antenna within said lower housing so that the electronic hearing aid of the user is further separated from said multi-frequency band antenna when said upper and lower housings are in the extended use position to thereby reduce undesired coupling with the electronic hearing aid; said multi-frequency band antenna comprising a dielectric substrate and a plurality of conductive traces thereon defining a main loop conductor having a gap therein.
