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 utility model 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, the utility model dual-polarization radiating unit 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.
