[embodiment]
Please refer to Fig. 1 to shown in Figure 3, combined antenna 100 of the present invention mainly is to be made of three kinds of basic antennas such as a spike antenna 10, a helical antenna 20 and dipole antennas 30.Wherein this spike antenna 10, helical antenna 20 and dipole antenna 30 are to connect to form according to series system.This dipole antenna 30 comprises that length is substantially equal to the Department of Radiation 31 and the grounding parts 32 of 1/4 carrier wavelength respectively.The Department of Radiation 31 of dipole antenna 30 is connected in helical antenna 20 lower ends, helical antenna 20 upper end connecting rod antennas 10.
One feeder line 40 is connected with dipole antenna 30, and it has the inner wire 41 that is connected with the Department of Radiation 31 of dipole antenna 30, inner insulating layer 42, the metal shielding layer 43 that is connected with the grounding parts 32 of dipole antenna 30 and the external insulation layer 44 of clad metal shielding layer 43 that coats inner wire 41.Grounding parts 32 is made of metal, and it comprises drum portion 321 that is positioned at the lower end and the conus portion 322 that is positioned at the upper end.Conus portion 322 tops have the perforate 33 that can supply inner wire 41 to pass, and drum portion seals substantially 321 bottoms but leaves an aperture that can supply feeder line 40 to pass.The metal shielding layer 43 of feeder line 40 is welded in around the perforate 33 on conus portion 322 tops.The one plastic cement drum 60 with through hole 61 is sheathed on the inner wire 41 of feeder line 40 and Department of Radiation 31 welds of dipole antenna 30, and plastic cement drum 60 bottoms are resisted against on the conus portion 322 of grounding parts 32.So, plastic cement drum 60 covers weld and the metal shielding layer 43 and conus portion 322 welds of inner wire 41 and Department of Radiation 31 fully, not only make these welds not easy fracture or damage, and make these welds be difficult for oxidized and keep electrically connecting preferably.
One round barrel shape metal forming 70 is wound on plastic cement drum 60 and the grounding parts 32, and the bottom is held on the grounding parts 32.This metal forming 70 forms electric capacity with grounding parts 32, thereby makes combined antenna 100 reach impedance matching.Metal forming 70 is the center with the feeder line weld, and its a part of self-feed line weld extends upward, and another part self-feed line weld extends downwards.Metal forming 70 scribbles conducting resinl with plastic cement drum 60 with the one side that grounding parts 32 contacts, and because plastic cement drum 60 hardness are less, metal forming 70 can stick on the plastic cement drum 60 by banding, thereby plastic cement drum 60, grounding parts 32 and metal forming 70 threes are retained on together mutually.Metal forming 70 can be aluminium foil, Copper Foil or other metal.
During assembling, the Metallic rod of suitable length is bent out the Department of Radiation 31 of spike antenna 10, helical antenna 20 and dipole antenna 30, this three part can be bent to form by the Metallic rod one as above-mentioned, also can reach connection by welding by three separate parts.Grounding parts 32 is passed feeder line 40 and expose feeder line 40 inner wires 41, plastic cement drum 60 is passed the Department of Radiation 31 of dipole antenna 30, again Department of Radiation 31 is welded on the inner wire 41 of feeder line 40, is set in the feeder line weld and makes plastic cement drum 60 the latter halfs be sheathed on the conus portion of grounding parts 32 plastic cement drum 60 is drop-down then.The metal forming 70 that to post conducting resinl at last is wound on plastic cement drum 60 and the grounding parts 32.Combined antenna 100 outside sheathed shells 80 (as shown in Figure 4) are connected with RF connector 900 through a pivot part 90, are installed on then on the electronic equipment (not shown), and are exposed to device external.
