| 摘要 |
The invention relates to a device for transferring signals from at least one housing opening (2) of a housing (3), which is metallic at least in part, by means of electromagnetic waves (4) of at least one specific wavelength, comprising a transmitting/receiving unit (5) arranged in the housing (3) for generating and receiving the electromagnetic waves (4), at least one primary antenna (6) arranged in the housing (3) for decoupling the generated electromagnetic waves (4) of the transmitting/receiving unit (5) and for coupling and transferring received electromagnetic waves (4) to the transmitting/receiving unit (5), a first secondary antenna (7) for receiving the electromagnetic waves decoupled from the primary antenna (6), wherein the first secondary antenna is arranged within the housing (3) on the housing opening (2), a second secondary antenna (8) for receiving the electromagnetic waves (4) transferred from outside the housing (3), wherein the second secondary antenna (8) is arranged outside the housing (3) on the housing opening (2), wherein a reflection point (9) is arranged between the first and second secondary antennas (7, 8), such that an impedance jump occurs between the first and second secondary antennas (7, 8). |
