<p>PROBLEM TO BE SOLVED: To provide an antenna system for a hearing aid.SOLUTION: An antenna system includes a transceiver for wireless data communication interconnected with an antenna for emission and reception of an electromagnetic field. The antenna comprises a first section 19 having a length between at least one sixteenth wavelength and a full wavelength of the electromagnetic field and being positioned so that current flows in the first section in a direction substantially orthogonal to the body of a user (for example, for a hearing aid, substantially in parallel with an ear to ear axis of the user) when the antenna system is worn in its operational position by the user. Hereby, an electromagnetic field emitted by the antenna propagates along the surface of the body of the user with its electrical field substantially orthogonal to the surface of the body of the user. A binaural hearing aid system may includes at least one such hearing aid.</p> |
