Abstract
An antenna device for hearing instruments is particularly suited for ITE hearing instruments to be worn in the auditory canal. The system enables improved data transmission with increased transmission bandwidth with insignificantly increased space and energy requirements. An antenna arrangement with a coil core of magnetically permeable material has a preferred transmit and receive spatial direction. A further electric hearing instrument component emits electromagnetic interference radiation. A partially planar shield of magnetically permeable material is disposed between the antenna arrangement and the further component transversely to the transmit and receive spatial direction of the antenna arrangement and at a distance of 50 to 150 micrometers from the coil core. The distance is optimized to the fact that the signal-to-noise ratio has a maximum around 100 micrometers. The shield effect between antenna and further hearing instrument component initially increases with increasing distance and passes into saturation at about 100 micrometers.
