A hearing aid having a housing, comprising:
- a substrate carrying a wireless interface, the substrate further carrying a processor, the substrate arranged in the housing;
- an antenna arranged in the housing, the antenna being connected to the wireless interface;
- the antenna configured to emit and/or receive electromagnetic fields,
- an electronic element, connected to the processor via an electrical connection line,
- wherein a decoupling element is provided in the electrical connection line wherein the decoupling element has a characteristic frequency at the frequency, at which the antenna is tuned to radiate and/or receive the electromagnetic fields, so that the decoupling element provides at least a dampening of a signal around at least one of the operational frequencies of the antenna,
- wherein the antenna comprises an external part arranged outside the housing,
- wherein the hearing aid further comprises a battery, and
- wherein at least a part of the antenna is arranged at least partly around the battery.
