Description
The utility model relates to a kind of feedforward satellite earth antenna feed, the integrated feed of particularly a kind of C/Ku.
The integrated feed of C/Ku that uses both at home and abroad is two mouthfuls of output coupled modes at present, and its structure has two kinds, and a kind of is that C-band and Ku wave band all are garden waveguide probe coupling way of outputs; Another kind is that C-band is garden waveguide probe coupled modes, and the Ku wave band is an element antenna.The Ku wave band coaxial transmission line of these two kinds of feeds is all in C-band transmission garden waveguide, can only realize 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 the integrated feed of C/Ku 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: C-band is a coaxial transmission, level and vertical bipolar output, and the inner wire of C-band coaxial transmission is the straight-through waveguide of Ku wave band, the Ku wave band is that quadrature waveguide dual polarization is output as.Because the C-band of the integrated feed of C/Ku of said structure adopts coaxial transmission and Ku wave band to adopt straight-through waveguide, therefore the electromagnetic wave of transmit level polarization simultaneously within it and perpendicular polarization form can realize four-hole output.
The utility model compared with prior art has following advantage:
Since C-band and Ku wave band for transmitting respectively, so both signalling channels independently are independent of each other mutually.
2.Ku wave band adopts straight-through waveguide, so there is not the insertion loss.
3.C the phase center of wave band and Ku wave band overlaps, the elementary directional diagram of two wave bands is basic identical, makes two wave bands be best irradiation, therefore makes antenna at two wave bands higher efficient be arranged all.
4.Ku behind the interior hyper polarization sheet of straight-through waveguide, can realize circularly polarised on the ripple.
5. structure of the present utility model also can realize C/Ku integrated two mouthfuls or three mouthfuls of function feeds that output is many easily.
Below in conjunction with drawings and Examples the utility model is further described.

Referring to accompanying drawing 1,2,3,4, the delivery outlet of C-band coaxial waveguide 3 of the present utility model is 11 and 12, wherein 11 are window output, and 12 are probe output, and 1 is the coaxial waveguide transducer, the straight-through waveguide 2 of Ku wave band is positioned at C-band coaxial waveguide 3, it is into a single integrated structure that the quadrature waveguide 5 of Ku wave band and the straight-through waveguide 2 that is positioned at C-band can be done, and also can make the branch body structure, and Fig. 1 adopts the branch body structure, 8 is attachment screw, and 13 and 14 of Ku wave band is two delivery outlets of Ku wave band quadrature waveguide.In order to reduce the standing-wave ratio of Ku wave band quadrature delivery outlet, can add a polarization sheet 10,4 in the waveguide of Ku wave band quadrature is the chokes reflecting disc, and 7 and 9 is attachment screw, and 6 is sealing ring.
Two delivery outlets of C-band coaxial waveguide 2 also can be output of window output or hole and groove or slit coupling output, and shown in Fig. 5,6,7 is the C-band level and the vertical window way of output that is, and wherein 11 and 15 is two window delivery outlets.
The utility model can also be realized the function of two mouthfuls or three mouthfuls easily, the C-band or the Ku wave band that are about to above-mentioned integrated four-hole feed remove a delivery outlet arbitrarily, just can form the integrated three mouthfuls of feeds of C/Ku, as C-band is the single polarization of window or probe coupling output, the Ku wave band is three mouthfuls of integrated feeds of quadrature waveguide dual polarization output, reaching C-band is window and probe coupled modes dual polarization output, and the Ku wave band is three mouthfuls of integrated feeds of straight-through waveguide single polarization output.
