Abstract
The invention discloses a vehicle-borne STOM (satcom on the move) array antenna with gain increased by a lightweight dielectric lens. The vehicle-borne STOM array antenna comprises N*M square horn antennas of the same structure. Received vertically polarized and horizontally polarized signals are separated at a feed port of each horn antenna by a polarization separator. Two output ports of each horn antenna are connected to horizontal polarization and vertical polarization power divider networks through respective waveguides. The two power divider networks at two ends of an antenna board are connected with respective duplexers through waveguide rotary joints respectively. An input end of each horn antenna is connected with an emitting polarization controller through a waveguide. Emitted signals TX pass through emitter waveguide joints and are input into the emitting polarization controller. Output ends of the two duplexers are respectively connected with a receiving combiner through a waveguide. The combiner outputs signals RX to a frequency converter module at low noise. An aperture of each square horn antenna is covered with a dielectric grid plate and a parabolic dielectric lens. The weight of the vehicle-borne STOM array antenna made by ABS (acrylonitrile butadiene styrene) injection process and using the dielectric lens is lowered, and gain thereof is increased.
