Abstract: The invention relates to microwave technology and can be used in measuring technology and wireless communication. The technical result is a waveguide-to-microstrip transition which provides reduced signal transmission losses and increased working bandwidth together with a low wave reflection coefficient. A contacting metal layer is arranged on an upper surface of a dielectric circuit board around a micro-strip probe, without electrical contact with the micro-strip probe and a micro-strip transmission line and forming an internal area on the dielectric circuit boar being a waveguide channel area. A closed waveguide section having a slot in the area of the microstrip transmission line is arranged on the contacting metal layer. At least one metallized transition through-hole is formed along a perimeter around the area of the waveguide channel in the metal layers and in the dielectric circuit board, and at least one non-metallized through-hole is formed inside the waveguide channel area.

Abstract: Disclosed is a lens antenna comprising a dielectric lens consisting of a collimating part and an extension part, and an antenna element. The extension part of the lens comprises a substantially flat surface crossed by the axis of the collimating part, and the antenna element is rigidly fixed on the surface. The antenna element is formed by a hollow waveguide and comprises a dielectric insert with one end thereof adjacent to said surface; the size of the radiating opening of the waveguide is determined by the predefined width of the main beam and by side lobe levels of the radiation pattern of the lens antenna. The technical result of the invention is an increase in realized gain value due to the use of a waveguide antenna element with a dielectric insert, which provides impedance matching in a wide frequency bandwidth. The present invention can be used in radio-relay point-to-point communication systems, e.g.

Abstract: A radio-relay communication system having a radio-frequency transceiver units and a beam-scanning antenna is provided. It is configured for electronic scanning by switching between primary antenna elements. The system provides electronic scanning without losses or with 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.
