Document Type and Number:
Japanese Patent JP5683681
Kind Code:
B2
Abstract:
An antenna system, such as a hearing aid, is provided, comprising a transceiver for wireless data communication interconnected with an antenna for emission and reception of an electromagnetic field, wherein the antenna comprises a first section having a length being 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 when the antenna system is worn in its operational position by the user, such as, for a hearing aid, substantially in parallel with an ear to ear axis of the user. Hereby, an electromagnetic field emitted by the antenna propagates along the surface of body with its electrical field substantially orthogonal to the surface of the body of the user. A binaural hearing aid system may comprise at least one such hearing aid.
