The present disclosure relates to a device for transferring signals from at least one housing opening of a housing, which is metallic at least in part, by means of electromagnetic waves of at least one specific wavelength. The device includes a transmitting/receiving unit arranged in the housing; at least one primary antenna arranged in the housing; a first secondary antenna for receiving the electromagnetic waves decoupled from the primary antenna; and a second secondary antenna for receiving the electromagnetic waves transferred from outside the housing, wherein the second secondary antenna is arranged outside the housing on the housing opening, wherein a reflection point is arranged between the first and second secondary antennas, such that an impedance jump occurs between the first and second secondary antennas.
