The utility model content
Thereby problem to be solved in the utility model provides simple in structure, cost is low, the large-scale production reliability is higher relatively broadband dual polarized antenna oscillator that a kind of balance that has improved a period of time space radiation improves cross polarization characteristics.
For achieving the above object, broadband dual polarized antenna oscillator described in the utility model comprises: reflecting plate, surface emissivity unit, feed tab, supporting seat, described surface emissivity unit comprises the half-wave a period of time a period of time arm and the terminal syndeton of a period of time of hollow out, and a period of time arm of described radiating element connects successively by terminal syndeton of a period of time endways; Supporting seat is between surface emissivity unit and reflecting plate, and the top is by its top bossing and radiating element welding, and the below also is fixed on the reflecting plate by threaded connector by its below, and the line seat of supporting seat is partly welded with cable outer conductor; Feed tab is fixed on the supporting seat by three-piece, and its top and surface emissivity unit are by direct-connected feed structure or coupling feed structure feed, and lower end and cable inner conductor welding are so that feed.
The described direct-connected feed structure of such scheme is feed tab top and surface emissivity element solder.
The described coupling feed structure of such scheme feed is that feed tab does not contact with the metallic plate radiation fin but adds one section open-circuit line downwards.
The described supporting seat of such scheme is a single-casting, comprises supporting bracket, base, line seat, and supporting bracket is provided with and is used for fixing position, three-piece hole.
The beneficial effects of the utility model are: broadband dual polarized antenna oscillator described in the utility model, can be under the situation of basic structure that does not change antenna a period of time and basic electric property, effectively improve cross polarization characteristics to meet the demands, especially on ± 60 ° of directions; Owing to the raising of a period of time balance, electricity function indexs such as isolation also have some improvement simultaneously, have realized the low cost design of broadband dual polarized antenna oscillator, have reduced the oscillator building block, have simplified assembling process; Reduced the possibility that intermodulation signal produces, be more suitable in production in enormous quantities.

Embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are described in further detail:
Fig. 1 is the structural representation of the utility model broadband dual polarized antenna oscillator, comprises reflecting plate 1,2,2 feed tab 3 of metal sheet surface radiating element, supporting seat 4; 5,6 three-pieces 6 of attaching nut and packing ring, supporting seat 4 is between surface emissivity unit 2 and reflecting plate 1, the top is by its top bossing and radiating element 2 welding, the below and by its below be fixed on the reflecting plate 1 by attachment screw and nut 5, feed tab 3 is fixed on the supporting seat 4 by three-piece 6, its top and the direct-connected feed of surface emissivity unit 2 welding, lower end and cable inner conductor 20 welding are so that the feed (see figure 4).
Fig. 2 is the structural representation of radiating element.Metal sheet surface radiating element 2 is processed by a metallic plate, the half-wave a period of time a period of time arm 7,8 and the terminal syndeton 9 of a period of time that comprise hollow out, half-wave dipole a period of time arm 7 of two pairs ± 45 ° of quadratures, 8, syndeton 9 by end links to each other successively, constitutes the radiating element of a band dual polarization; Position, hole 10 is the solder joint of radiating element 2 and supporting seat; Position, hole 11 is the solder joint of feed tab and radiating element 2.The syndeton 9 of radiating element 2 can according to processing conditions and Antenna Design must cross polarization characteristics adopt different designs, adopt simple direct-connected mechanism in the present embodiment, its effect is one section impedance conversion line, and the symmetry that improves the oscillator own radiation is to improve cross polarization characteristics.
Fig. 3 a is the clamping support schematic diagram.Supporting seat is holistic foundry goods, comprises 12,1 bases 13 of 4 supporting brackets, line seat 15, and supporting bracket 12 is provided with the position, 6 holes 14 that is used for fixing three-piece 6.Be depicted as the fixing means of supporting seat 4 and feed tab 3 as Fig. 3 b, the position, hole that feed tab is passed supporting seat 4 by 6 three-pieces is fixed on above the supporting seat 4; And shown in Fig. 3 c, supporting seat 4 at first is positioned on the reflecting plate 1 by pilot pin 16, the circular hole 18 usefulness nuts 5 that screw 5 passes on reflecting plate 1 and supporting seat 4 bases 13 are tightened on reflecting plate 1, the marginal portion 17 of base 13 being attached on the reflecting plate 1 tightly like this, and screw pilot pin etc. be easy to generate the part closure of intermodulation signal, reduced the possibility that produces intermodulation signal.4 supporting brackets 12 and 2 feed tab 3 are welded on radiating element after then passing position, hole 10 and position, hole 11 on the radiating element 2 respectively.
