Abstract: The invention relates to millimeter-wave point-to-point communication systems. A system comprises two separated millimeter-wave transceivers which provide high throughput data transmission and reception in frequency duplex mode and use high gain antennas capable of electronic scanning in some continuous angle range provided by the control module that implement control algorithms for antenna radiation pattern. Also a method based on the exploitation of scanning antennas of initial beam directions fine adjustment and subsequent beam directions tracking and readjustment when needed is proposed. The proposed system and method provide automatic recovery of failed connection in case of relay station orientation change due to influence of various external factors (wind, vibration, different intensity of heating of the bracing mountings at different time of a day and others) and can be used in backhaul systems of base station sites for mobile networks.

Abstract: The invention provides a radio-relay communication system having a radio-frequency transceiver units and a beam-scanning antenna configured for electronic scanning by means of switching between primary antenna elements. The system provides electronic scanning without losses or low losses with each radio-frequency transceiver unit being electrically connected to at least one primary antenna element of the beam-scanning antenna. The antenna beam scanning is accomplished through the signal distribution units selecting at least one of radio-frequency transceiver units for processing of the received and generation of the transmitted signals in a given spatial direction.

Abstract: The invention discloses a lens antenna with high directivity intended for use in radio-relay communication systems, said antenna providing the capability of electronic steering of the main radiation pattern beam by switching between horn antenna elements placed on a plane focal surface of the lens. Electronic beam steering allows antenna to automatically adjust the beam direction during initial alignment of transmitting and receiving antennas and in case of small antenna orientation changes observed due to the influence of different reasons (wind, vibrations, compression and/or extension of portions of the supporting structures with the temperature changes, etc.). The technical result of the invention is the increase of the antenna directivity with simultaneously provided capability of scanning the beam in a continuous angle range and also the increase of the antenna radiation efficiency and, consequently, the increase of the lens antenna gain.
