As a kind of improvement project, each radiation support arm comprises main part and end, and the junction of described end and main part forms kink.
As a kind of improvement project, described radiation groove extends along the main part of corresponding radiation support arm, or extends along main part and end thereof.
As a kind of improvement project, each supports Ba Lun two radiation support arms is installed, and the main part of described two radiation support arms extends along contrary direction.
As a kind of improvement project, the main part of each radiation support arm is basically curved.
As a kind of improvement project, described feed structure comprises: cable, and described cable is installed to and supports Ba Lun and extend to described radiation support arm, and the outer conductor of cable and described support Ba Lun are electrically connected; The feed bridge, described feed bridge is installed to described two radiation support arms, and an end and one of them radiation support arm are electrically connected, and the other end and cable inner core are electrically connected.
As a kind of improvement project, described one of them radiation support arm has boss for being electrically connected with described feed bridge, and described support Ba Lun has groove for accommodating described cable.
As a kind of improvement project, each supports Ba Lun and has two spaced support arms of tool, and each support arm supports a corresponding radiation support arm.
As a kind of improvement project, described support Ba Lun is arc or Curved.

[embodiment]
Referring to figs. 1 to Fig. 7, dual polarized antenna provided by the invention comprises reflecting plate 1 and is installed to the radiating element of reflecting plate.
Each radiating element comprises 4 radiators, and each radiator comprises that one is supported Ba Lun, feed structure and at least two radiation support arms.Described at least two radiation support arms are installed to the top of supporting Ba Lun, and feed structure is installed to described two radiation support arms.In this example, each radiator comprises two radiation support arms, and each extends suitable length towards different direction these two radiation support arms, and makes the radiation support arm of adjacent radiation device have appropriate gap.
In this example, each radiation support arm 2 comprises main part and end, and the junction of described end and main part forms kink.The end of adjacent radiation support arm 2 is orthogonal.For example, two adjacent end 10 along continuous straight runs are towards radiating element inside, and another organizes two adjacent ends 11 vertically towards reflecting plate 1.The radiation support arm has the radiation groove 3 of strip, and the shape of strip radiation groove 3 is similar to radiation support arm 2, and size is less than radiation support arm 2, strip radiation groove 3 of each radiation support arm 2 each embedding.Described radiation groove extends along the main part of corresponding radiation support arm, or extends along main part and end thereof.
Feed structure comprises feed bridge 4 and cable.Feed bridge 4 is positioned at the top of a pair of radiation support arm 2, and insulating washer 12 is sandwiched between radiation support arm 2 and feed bridge 4, plays the effect of insulation with level altitude.Feed bridge 4 one ends are welded on the boss 6 of radiation support arm, and an other end is welded on the inner core 5 of cable.The every pair of radiation support arm 2 be connected with feed bridge 4 links into an integrated entity with base 8 by supporting Ba Lun 7, by four screw holes 9, is fixed on reflecting plate 1.The mutual symmetry of every group leader's strip radiation groove the mirror image that are positioned at same electric bridge 4 are paired.
In the present invention, similar to the primary radiation support arm by each radiation support arm inside, opening a shape, the strip radiation groove that size is less than primary radiation support arm, the effect of strip radiation groove mainly contains: alleviate radiating element weight thereby reduce metal material, reach and reduce costs purpose; The three-dimensional groove of polygon makes original radiation support arm become polygonized structure by square entity structure, can guarantee in the situation of operational frequency bandwidth, make the signal energy transmission more concentrated, thereby the enhanced rad energy improves gain, improve and guaranteed that the property indices of oscillator comprises: cross polarization discrimination, the beamwidth convergence, compare etc. front and back; Being made of one of oscillator, simplified assembly process simultaneously, can effectively reduce the cost, and improves productivity effect.
For the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
