Abstract

A device for transferring signals using electromagnetic waves of a certain wavelength and based on a housing formed at least partially of metal for use in an explosion endangered area includes the housing; a transmitting/receiving unit for producing and/or receiving the electromagnetic waves; at least one primary antenna for out-coupling and/or in-coupling of the electromagnetic waves; at least one slot-shaped housing opening; and a formed part, which is made of a material having a dielectric number significantly greater than one and which extends to a predetermined maximum depth into the housing opening.
