Embodiment
For describing technology contents of the present utility model, structural feature, the purpose that realizes and effect in detail, below give explanation especially exemplified by embodiment and conjunction with figs. are detailed.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model dual polarization broadband radiating element 200 has a supporting seat 210 and vertically extends four next radiation fins 220 from this supporting seat 210, these four radiation fins 220 are positioned at same plane and are 90 degree along central point and are symmetrically distributed, two relative radiation fins 220 are one group of symmetrical dipole that forms an equivalence, two orthogonal thereto distributions of symmetrical dipole, thereby this+45 ° and-45 ° polarised direction A of four radiation fins, 220 formation and B.
Supporting seat 210 has a base plate 211.This base plate 211 upwards vertically extends four support arms 212.The cross section of two adjacent support arms 212 wherein is arcs of recesses, thereby forms a groove 213 that extends up and down, and this groove 213 is used for guiding feeder line 300.The heart yearn of feeder line 300 is welded on the feed tab 230, and 230 pairs of two relative radiation fins 220 of this feed tab carry out feed, thereby two relative radiation fins 220 radiate corresponding polarized signal.
In the present embodiment, radiation fin 220 roughly is square, and the otch of the end of radiation fin 220 is one 45 ° otch, i.e. edge 222 and be 45 ° with angle between the both side edges 221 that this edge 222 is connected.Two penetrating grooves 223 are all L-shaped, to increase the length of penetrating groove.
