<P>PROBLEM TO BE SOLVED: To provide improved wireless communication in an antenna system provided in a hearing aid. <P>SOLUTION: An antenna system comprises a transceiver 3 for wireless data communication which is interconnected with an antenna for emission and reception of an electromagnetic field. A first section 19 of the antenna has a length being between at least one sixteenth wavelength and a full wavelength of the electromagnetic field. When the antenna system is worn in its operational position by a user, the first section 19 is positioned so that current flows in the first section 19 in a direction substantially orthogonal to the body of the user, whereby the electromagnetic field emitted by the antenna propagates along a 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 comprises at least one such a hearing aid assembly 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
