The transmission of signal be unable to do without antenna for base station with covering in the mobile communication technology, and in densely populated zone, Bipolarization antenna for base station more becomes the indispensable part in each base station with its superior polarization diversity characteristic, and its performance directly influences the quality of communication.And dual-polarization radiating unit is the key component that influences the Bipolarization antenna for base station performance as the element of Bipolarization antenna for base station.
But the gain of existing dual-polarization radiating unit is lower, cost is higher, complex structure, assembling trouble, can't guarantee higher communication quality in the service area.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of height that gains, isolation height and the low dual-polarization radiating unit of cross polarization level are provided.
Technical scheme: dual-polarization radiating unit of the present invention, comprise symmetrical dipole, chassis and Ba Lun sheet, described symmetrical dipole is 4 groups, every group of symmetrical dipole is fixed on the place, four angles on described chassis by a pair of supporting leg; Described Ba Lun sheet is 4, and 4 Ba Lun sheets are separately positioned between 4 pairs of supporting legs; One end of described Ba Lun sheet connects with the one arm of corresponding symmetrical dipole, the other end stretches out the bottom on described chassis and is provided with cable bonding wire seat and cable-fed hole, the coaxial feeder cables outer conductor is connected by soldering with described cable bonding wire seat, the coaxial feeder cables heart yearn is connected by soldering with described cable-fed hole, thereby the realization coaxial feeder cables is carried out feed to oscillator.Form the scheme of radiating element with respect to four independent symmetrical dipole unit and compare, this integral structure can reduce the fixing point on unit and floor, and the passive intermodulation index that is of value to integrated antenna improves.
Preferably, 4 groups of symmetrical dipoles are parallel in twos, and with square or rhombus mode group battle array, two parallel symmetrical dipoles have increased effective radiating aperture of unit, thereby have further realized the characteristics that module gain is high.
Preferably, the downward bending in the one or both ends of described symmetrical dipole, dipole arm is bent with downwards and is beneficial to the further Bipolarization antenna for base station cross polarization ratio that improves.
Preferably, 4 groups of symmetrical dipoles are fixed on the described chassis, constitute integral structure; All constituents has guaranteed the relative spacing consistency height of four groups of symmetrical dipoles all by integrated die casting/moulding by casting.
Preferably, described chassis is provided with a plurality of rivet holes, is convenient to radiating element and the floor is fixed by rivet/screw.
For guaranteeing the mechanical strength of radiating element integral body, bending on four side direction on radiating element of the present invention chassis.
The present invention compared with prior art, its beneficial effect is: 1, dual-polarization radiating unit of the present invention has electric properties such as module gain height, isolation height and cross polarization level are low by structure that four groups of symmetrical dipoles are formed a whole; 2, the present invention has guaranteed the relative spacing consistency height of four groups of symmetrical dipoles by integrated die casting or cast molding, has sound construction, easy to assembly, high conformity simultaneously, is fit to the advantage of producing in enormous quantities; 3, the Bipolarization antenna for base station of being made up of radiating element of the present invention can significantly improve communication quality in the base station service area.
