Technical field
The present invention relates to a kind of antenna radiation unit, relate in particular to a kind of broadband dualpolarization radiation unit of TD-LTE smart antenna.
Background technology
Mobile communication had obtained developing rapidly in recent years, in order to better meet user's request, operator need provide better, 3G broadband services faster, therefore existing TD-SCDMA(Time Division-Synchronous Code Division Multiple Access, the TD SDMA access technology) intellectual technology develops TD-LTE(TD-SCDMA Long Term Evolution, TD-SCDMA Long Term Evolution) intellectual technology; In order to satisfy the demand of operator, we want the bandwidth of operation of extended antenna.The working band of existing TD-SCDMA smart antenna is 1880-1920MHz and 2010-2025MHz two-band, and the working band of TD-LTE smart antenna has expanded to 1880-1920MHz, 2010-2025MHz and 2570-2620MHz three frequency ranges, and the basic radiating element that existing TD-SCDMA smart antenna uses can't cover 1880-1920MHz, 2010-2025MHz and 2570-2620MHz three frequency ranges.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of dual-polarization radiating unit of the TD-LTE broad band intelligent antenna that can frequently cover 1880-1920MHz, 2010-2025MHz and 2570-2620MHz three is provided.
Technical scheme: TD-LTE dual-polarization radiating unit of the present invention, comprise symmetrical dipole radiation arm, feed Ba Lun and support arm, described symmetrical dipole radiation arm is two pairs, two pairs of symmetrical dipole radiation arms intersect and are cross distribution; Every pair of symmetrical dipole radiation arm is fixed on the floor by support arm respectively; Described feed Ba Lun is 2, and the end of each feed Ba Lun connects with the one arm of corresponding symmetrical dipole radiation arm, and the other end is fixed on the bottom of the support arm of one arm in addition of corresponding symmetrical dipole radiation arm.
Relatively good for effect is installed, the bottom of described support arm is provided with the installation medium, and the other end of described feed Ba Lun is fixed on the bottom of described support arm by described installation medium.
Coaxial cable is installed for convenience, and the bottom of described support arm is provided with a pair of coaxial cable installing hole.
Two symmetrical dipole radiation arms and support arm constitute integral structure, and two groups of symmetrical dipole radiation arms are designed to the one-shot forming of one pressure injection, are convenient to the accurate of design size like this; Simultaneously the radiation arm bottom is designed to boss structure and is used for the location.
Described feed Ba Lun one end is connected by riveted joint with dipole arm.
In order further to strengthen the cross polarization effect, the described symmetrical dipole radiation arm of inventor is set to plane tabular, and the centre is provided with engraved structure.
In order to reduce the weight of described symmetrical dipole radiation arm, economical with materials, the outside of described symmetrical dipole radiation arm is set to the recessed arc in inside.
The present invention compared with prior art, its beneficial effect is: 1, owing to adopt the vertical ground connection with supporting arm of two symmetrical radiation arms of symmetrical dipole, feed Ba Lun is riveted on the symmetrical radiation arm, this makes two the relative supporting arms of symmetrical radiation arm, feed Ba Lun and ground structure symmetries of symmetrical dipole, distributed capacitance is identical, finishes unbalanced line and gives the mapping function of the desired imbalance of symmetrical antenna feed to balance; Electric property such as 2, dual-polarization radiating unit of the present invention has the module gain height, working band is wide, isolation is high and cross polarization level is low, because radiating element adopts injection-compression molding with the two symmetrical dipoles structure that forms a whole, improve the radiating element accuracy requirement, it is convenient to install, and enhances productivity.
