ABSTRACT:
A device for receiving and/or transmitting an electromagnetic oscillation is described utilizing an antenna element and at least two wave-guiding assemblies which are each connected to a connection point of the antenna element via a respective supply device, and which are otherwise mutually insulated with respect to the electromagnetic oscillation. Each assembly comprise a conductor part which is coupled to the associated supply device in each of the wave-guiding assemblies for the transmission of the electromagnetic oscillation. The wave-guiding assemblies are designed for receiving and/or transmitting the electromagnetic oscillation via the supply device, and the conductor parts are constructed for receiving and/or radiating the electromagnetic oscillation in a manner comparable to the manner in which the antenna element operates. This device has a plurality of antennas without an appreciable increase in expenditure compared with a similar device having a single antenna element.
