Abstract: An antenna system is provided for hearing instruments to be worn in the auditory canal. A hearing instrument has a data transmission system improved in respect of transmission bandwidth with no increase or only an insignificant increase in space and energy requirement. The antenna system has an antenna with a preferred send and receive spatial direction, and a hearing instrument component which emits noise radiation predominantly in a noise radiation spatial direction. The antenna and the hearing instrument component are disposed so that the send and receive spatial direction and the noise radiation spatial direction are oriented transverse to one another such that a coupling-in of noise radiation into the antenna is reduced. The reduction of the noise couplings into the antenna make possible a higher send and receive bandwidth, with the installation volume and energy requirement remaining the same. The hearing instrument component is a receiver.
