Description
The utility model relates to a kind of satellite and receives rear feed antenna, particularly a kind of C/Ku two waveband, dual polarization rear feed antenna.
The progress of satellite technology at present is to adopt frequency and polarization multiplexing technology, make satellite transmit C-band and the horizontal polarization of Ku wave band and the TV signal of perpendicular polarization to the earth simultaneously, so just require terrestrial television Satellite Receiving Station antenna technology synchronized development, promptly can receive C-band and the level of Ku wave band and the four kinds of TV signal of perpendicular polarization that satellite is transmitted simultaneously with a surface antenna.The satellite TV ground receiving station antenna is divided into feedforward and rear feed two class antennas.The rear feed antenna has only C-band single polarization or dual polarization output coupled mode and Ku wave band single polarization or dual polarization form at present, be that the rear feed antenna can only be realized a kind of polarization output, be horizontal polarization output or perpendicular polarization output, therefore, when needs receive the TV signal of the C-band transmitted on the satellite and Ku wave band level and four kinds of states of perpendicular polarization simultaneously with a surface antenna, just do not satisfy requirement.
The purpose of this utility model is to provide a kind of can receive the C-band transmitted on the satellite and C/Ku two waveband, the dual polarization rear feed antenna of Ku wave band level and four kinds of state TV signal of perpendicular polarization simultaneously with a surface antenna.
The purpose of this utility model realizes by following measure: a kind of C/Ku two waveband, dual polarization rear feed antenna comprise primary reflection surface, subreflector, feed and antenna mount four parts, its characteristics are: feed is a kind of two waveband, dual polarization compound feed, its C-band signal is the coaxial waveguide transmission, level and perpendicular polarization are probe and window output, or be probe or be window output, the straight-through waveguide that the Ku band signal is made for the coaxial waveguide inner wire, level and perpendicular polarization are the quadrature waveguide.Because the antenna feed C-band of said structure adopts the coaxial waveguide transmission, the Ku wave band adopts straight-through waveguide, the electromagnetic wave of transmit level polarization simultaneously within it and perpendicular polarization, so can realize receiving the TV signal of four kinds of states.
The utility model compared with prior art its advantage is to save a surface antenna, jam lattice logical sequence rear feed antenna two waveband, dual-polarized reception have simultaneously been realized, on this architecture basics, can realize the conversion of C-band two-wire, two circularly polariseds, the Ku wave band is easy to realize circularly polarised, has promptly realized the multifunctionality of jam lattice logical sequence rear feed antenna.
