Problems solved by technology
like figure 1 and figure 2 As shown, at present, the TD-LTE base station antenna radiating unit is mainly composed of a first guide sheet 1', a second guide sheet 2', a support element 3', a first feed sheet 4', and a second feed sheet 5' 1. The main body of the radiation unit 6' is welded. The structure of the cross-polarized coupling radiation unit has the following disadvantages: 1. It is easy to cause oxidation, shedding, sharp protrusions, air holes, pinholes, short circuits, solder joints or welding beads of solder joints, etc. Defects will have a certain impact on electrical performance; 2. The processing and assembly are complicated, the assembly time is long, and the efficiency is low, which is not conducive to mass production; 3. There are many raw materials to process and the cost is high; 4. The processing accuracy is difficult to control, because the welding Fixtures and human factors have many factors affecting product accuracy, and the consistency is poor
