A hearing aid device has an antenna device. The antenna device is configured to receive and/or transmit electromagnetic waves of a predetermined wavelength lambda. The antenna device has an energy coupling device which is configured to supply or to draw electrical energy to or from the antenna device. The antenna device has a first conductor and a second conductor, which are in energy exchange with the energy coupling device, extend away from the energy coupling device in different directions and are arranged a short distance from a third conductor. A first ohmic connection between the first conductor and the third conductor and a second ohmic connection between the second conductor and the third conductor are arranged at a predefined distance from the energy coupling device.
