Upward tapering of the present utility model and hypocone refer to the shape that is taper generally, and its conical surface can include slight circular arc and heave shape.
Dual-polarization omnidirectional antenna needs to connect the coaxial cable of perpendicular polarization feed and the coaxial cable of horizontal polarization feed when connecting coaxial cable.
The coaxial cable of perpendicular polarization feed carries out feed to the perpendicular polarization unit.The inner wire of the coaxial cable of perpendicular polarization feed is connected in the top in tapering and realizes and the first perpendicular polarization oscillator conducting; The outer conductor of the coaxial cable of perpendicular polarization feed is connected in the top of hypocone and realizes and the second perpendicular polarization oscillator conducting.The feed connector can be set with the conducting of the realization coaxial cable outer conductor of perpendicular polarization feed and the second perpendicular polarization oscillator on the top of hypocone, and to fixing that the coaxial cable of perpendicular polarization feed should be held.Between last tapering and hypocone, preferably also be provided with insulation spacer, to prevent that both are in this position short circuit.
The coaxial cable of horizontal polarization feed carries out feed to the horizontal polarization unit.The horizontal polarization unit comprises insulation medium board, is shaped on first plane dipole in the one side of insulation medium board, is shaped on second plane dipole at the another side of insulation medium board.According to existing connected mode the coaxial cable of horizontal polarization feed and horizontal polarization unit are connected together and get final product.As required, its first plane dipole of described horizontal polarization unit and second plane dipole can be mutual conductings, also can be mutual insulatings.
When the outer cover of supporting existing specification and base plate, the second perpendicular polarization oscillator can block the lead outlet of base plate central authorities, and the coaxial cable of perpendicular polarization feed this moment can be drawn from lead outlet, and the coaxial cable of horizontal polarization feed can not be drawn from this lead outlet.For addressing this problem, can make coaxial cable via hole at hypocone, so that the coaxial cable of horizontal polarization feed can be through this hole and lead outlet and drawn, guarantee that existing outer cover and base plate stand good.
As improvement, this omnidirectional antenna circumferentially also preferably is provided with parasitic patch equably last annulus portion.
Dual-polarization omnidirectional antenna of the present utility model have volume little, can use existing specification outer cover, cost lower, safeguard and advantage such as upgrading is convenient.
