[0032] The feeding network module 1 comprises a feeding strip 11, a plastic support 12 and a reflecting plate spring 13. The feeding strip 11 and the reflecting plate spring 13 are fixed on two different surfaces of the plastic support 12 respectively.

[0033] In actual operation, the feeding strip 11 and the reflecting plate spring 13 are metal sheets formed by precision stamping. The feeding strip 11 can also be a metal sheet formed by laser cutting or etching, with a thickness of 0.15-0.3 mm and a surface subjected to electroplating anticorrosion treatment. The feeding strip 11 is uniformly and reasonably provided with a plurality of through holes with a diameter of 1.0-1.2 mm and a spacing of 10-20 mm.

[0034] The plastic support 12 is made of engineering plastic and is realized by mold injection. One side of the plastic support 12 facing the feeding strip 11 is provided with a plurality of cylindrical structures corresponding to the through holes of the feeding strip 11 one by one, with a diameter of 0.8-1.0 mm. The feeding strip 11 is arranged on the plastic support 12 in accordance with the corresponding cylindrical structures of the through holes, and the cylindrical structures of the plastic support 12 are higher than the thickness of the feeding strip 11. The feeding strip 11 and the plastic support 12 are fixed together by hot melting.

[0035] The reflecting plate spring 13 is arranged on the other side of the plastic support 12. In one implementation, the reflecting plate spring 13 is fixed on the other side of the plastic support 12 by back glue.

[0036] The plastic support 12 is further provided with a first hot melting column 121, and the antenna radiation module 2 is fixed on the plastic support 12 by the first hot melting column 121. The antenna radiation module 2 comprises a first radiation sheet 21, a second radiation sheet 22 and a support frame 23. The first radiation sheet 21 is fixed on the plastic support 12 by the first hot melting column 121. The feeding strip 11 and the first radiation sheet 21 are located on the same surface of the plastic support 12.

The first radiation sheet 21 and the second radiation sheet 22 are provided with four clamping slots respectively. In the production process, the clamping claws and the clamping slots can be matched with each other to realize accurate positioning, facilitate rapid assembly, and improve the efficiency.

[0041] In practical application, the first radiation sheet 21 and the second radiation sheet 22 are square metal sheets.

The four L-shaped support seats 241 are located on the same surface of the plastic support 12 as the feed strip 11.

[0048] Combining Figure 5 and Figure 6 , any L-shaped support seat comprises two upper surfaces, one of which is higher than the other.

[0053] The feed band line 11, the first radiation sheet 21 and the second radiation sheet 22 are spaced apart at a certain interval for electromagnetic coupling. The interval between the feed band line 11 and the first radiation sheet 21 is determined by the height of the cross-shaped boss 122, and the interval between the first radiation sheet 21 and the second radiation sheet 22 is determined by the height difference between the two upper surfaces of the L-shaped support seat. The specific interval can be set by a technician according to actual application.

[0054] Further, the reflecting plate spring 13 is provided with an adhesive on the surface, and the reflecting plate spring 13 is attached to the surface of the plastic support 12 by the adhesive.

[0055] It should be noted that the structure of the feed band line 11 is diverse. Compared with the feed band line in the first embodiment, the feed band line in the second embodiment increases the bending process, so that it has more diverse forms to meet the use requirements.
