FIELD: radio engineering, communication.
SUBSTANCE: disclosed is a lens antenna for use in high-directivity radio relay systems, capable of electronically controlling the main beam of the beam pattern by switching between horn antenna elements, lying on the flat focal surface of the lens. Electronic beam scanning enables beam adjustment during primary adjustment of receiver and transmitter antennae and during small changes in spatial orientation of radio relay stations due to various external factors (wind, vibrations, compression/expansion of parts of the bearing structure due to temperature changes, etc).
EFFECT: high directivity while providing a continuous sector of scanning angles, and high efficiency of radiation and, as a result, high gain of the lens antenna used to establish a radio connection.
