[0002] As a mobile communication terminal, base station antennas are generally composed of radiating units of the same form combined into an array to obtain high gain. The performance of the radiating unit, such as gain, cross-polarization ratio, front-to-back ratio, etc., also directly affects the overall antenna performance.

[0003] The existing 0709 broadband combined oscillator radiation unit has a large diameter and low isolation. In the mainstream medium and low frequency coaxial antenna market, the medium and low frequency oscillators are coaxially embedded.

In addition, the assembly and welding are complicated and costly, making it difficult to improve production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0025] This specific implementation is a power splitter integrated radiation unit, and its structural diagram is as follows Figure 1-Figure 5 As shown, the integrated radiation unit includes an annular seat 1, on which two feeding assemblies 2 are arranged, and the outer surface of the annular seat 1 is provided with four radiation units, the radiation unit includes a first vibrator wall 3 and a second vibrator wall 4, one end of the first vibrator wall 3 and the second vibrator wall 4 are respectively fixedly connected with a first vibrator 5 and a second vibrator 6, the annular seat 1, the first vibrator wall 3, the second vibrator wall 4, the first vibrator 5 and the second vibrator 6 are integrally formed, and a vibrator insulation fixing seat 7 is arranged on the lower surface of the annular seat 1.

[0026] like Figure 3 and Figure 5 As shown: the feeding assembly 2 includes a feeding core 201 arranged on the annular seat 1 and a cable 202 welded and fixed to the feeding core 201. The vibrator power divider is integrated on the vibrator with high integration, eliminating two external power dividers and simplifying the assembly and welding process. A mounting groove 203 is provided on the first vibrator wall 3, and a protrusion 204 is fixedly connected to one end of the first vibrator wall 3 away from the annular seat 1. A card slot 205 is provided on the protrusion 204, and the other end of the cable 202 is welded and fixed in the card slot 205 along the mounting groove 203.

[0027] In this way, the four feeding cables 202 on the front are placed along the vibrator arm in the installation groove 203, which is convenient for installation and subsequent assembly welding. At the same time, the cable installation groove 203 installed on the front can protect the feeding cables 202. The design of the card slot 205 facilitates the welding of the other end of the cable 202 and improves the welding efficiency.

[0028] like Figure 1 and Figure 2 As shown, a gap is formed between the first vibrator wall 3 and the second vibrator wall 4 , and a reinforcement bone 8 is fixedly connected between the first vibrator wall 3 and the adjacent second vibrator wall 4 .

[0029] Setting the low-frequency vibrator coupling gap and the short-circuit grounding reinforcement bone position 8 in this way improves the standing wave and isolation stability of the single vibrator. At the same time, the four grounding short-circuit reinforcement bone positions 8 structurally strengthen the structural strength of the four vibrator arms.

[0030] like Figure 1 and Figure 2 As shown: the ends of the first vibrator 5 and the second vibrator 6 that are close to each other are both vertically fixedly connected with a guide arm 9.

[0031] Such arrangement of the guide arm 9 can broaden the working bandwidth of the vibrator and effectively cover more frequency bands.

[0032] like Figure 3 As shown: a first reinforcing buckle 10 is installed between the first vibrator 5 and the second vibrator 6 , and a second reinforcing buckle 11 is installed between the first vibrator 5 and the adjacent second vibrator 6 .

[0033] In this way, the vibrator arm is fixedly connected into a whole through the first reinforcing buckle 10 and the second reinforcing buckle 11, which not only maintains the lightweight design of the vibrator but also strengthens the structural strength of the vibrator arm, thereby achieving the purpose of reducing costs and solving the common problem of insufficient structural strength of the vibrator arm.

[0034] like Figure 3 and Figure 4 As shown: the vibrator insulating fixing seat 7 includes a mounting seat 701 corresponding to the annular seat 1, three first buckles 702 are fixedly connected to the upper surface of the mounting seat 701, and two second buckles 703 and two guide pillars 704 are fixedly connected to the lower surface of the mounting seat 701.

[0035] This arrangement facilitates the assembly of the vibrator by assisting the fixation with the first buckle 702, and the second buckle 703 facilitates the fixation with the reflector.

[0036] like Figure 3 and Figure 4 As shown: a plurality of positioning holes 705 are formed on the mounting seat 701 , and mounting posts 706 corresponding to the positioning holes 705 are fixedly connected to the lower surface of the annular seat 1 .

[0037] The vibrator is arranged in this way with the vibrator insulating fixing seat 7 as auxiliary fixation, and the self-tapping screws and the mounting column 706 are fixed to reduce the cost of the vibrator and save the cost of tapping the screw holes.

[0038] Working principle: during assembly, the cut coaxial feeding cable 202 is welded to the feeding component 2 and the slot 205, and the cable 202 is fixed in the mounting slot 203 in the vibrator wall, and then the annular seat 1 is fixed to the mounting seat through the first buckle 702, and then the reflector is fixedly connected to the positioning hole 705 on the mounting seat 701 with a self-tapping screw, and finally a cable 202 is led out for array use. Since the vibrator arm is fixedly connected as a whole by the first reinforcing buckle 10 and the second reinforcing buckle 11, the lightweight design of the vibration-preserving vibrator strengthens the structural strength of the vibrator arm while achieving the purpose of reducing costs and the common problem of insufficient structural strength of the vibrator arm. The four grounding short-circuit reinforcing bone positions 8 structurally strengthen the structural strength of the four vibrator arms. The vibrator power divider is integrated on the vibrator with high integration, eliminating two external power dividers and simplifying the assembly welding process. The design of the slot 205 facilitates the welding of the other end of the cable 202 and improves the welding efficiency.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
