Abstract
An apparatus for transferring signals from an at least partially metallic housing with the aid of electromagnetic waves of a particular wavelength comprises a transmitter/receiver unit located in the housing for generating and receiving the electromagnetic waves; at least one primary antenna located in the housing for coupling out the generated electromagnetic waves from the transmitter/receiver unit and for coupling in and transferring received electromagnetic waves to the transmitter/receiver unit; at least one slot-shaped housing opening designed such that a length of the slot-shaped housing opening is an integer multiple of a quarter of the particular wavelength and such that the slot-shaped housing opening, in cooperation with the primary antenna, transfers the signals with the aid of the electromagnetic waves into or out of the housing.
