ABSTRACT:
Disclosed is an antenna for use in transmitting and/or receiving both optical, including infrared, and high-frequency electro-magnetic radiation. The antenna is comprised of a hollow conductor in the interior of which is arranged a light conductor as a dielectric. Arranged in the wall of the hollow conductor is at least one slot which acts as an input and/or output coupling opening for the hollow conductor and as an inlet and/or outlet window for optical radiation. Also disclosed is an antenna assembly unit consisting of a plurality of the individual antennas arranged to give omni-directional capabilities for receiving and transmitting of optical and high-frequency electro-magnetic radiation.
