Bte hearing instrument comprising a loop antenna

A hearing instrument comprising a behind-the-ear (BTE) part to be worn behind the ear of a user, the BTE-part comprising:

• a first side, a second side substantially parallel to the first side, and a third side connecting the first side and the second side, wherein the first and second side are substantially parallel to the user's skin when the BTE part is worn behind the ear,
• a loop antenna comprising a loop conductor located at and substantially parallel to the third side of the BTE part and having a U-shaped contour comprising two legs connected by a base portion, a tuning capacitor comprising a first capacitor plate provided at the free end of one of the legs of the loop conductor and located at and substantially parallel to the first side and a second capacitor plate provided at the free end of the other one of the legs of the loop conductor and located at and substantially parallel to the second side, and a differential feed structure connected to each of the legs at a feed point, wherein the free ends of the legs of the loop conductor with the capacitor plates are located closer to a battery of the hearing instrument than the base portion of the loop conductor;
• and
• a transceiver designed for transmission and reception at frequencies from 1 to 6 GHz and connected to the differential feed structure of the antenna via a transmission line.
