[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 3A radiation unit assembly comprises a feeding base plate 1 and two radiation units respectively arranged at both ends of the feeding base plate 1, wherein the radiation unit comprises a radiation panel 2, a mounting seat 3 and two feeding plates 4; the radiation panel 2 is arranged at the top of the mounting seat 3, and the feeding base plate 1 is arranged at the bottom of the mounting seat 3; the two feeding plates 4 are orthogonally arranged inside the mounting seat 3, the top ends of the two feeding plates 4 are respectively connected to the radiation panel 2 for feeding, and the bottom ends of the two feeding plates 4 are respectively connected to the feeding base plate 1 for feeding; a plurality of clamping parts 331 are provided at the bottom of the outer wall surface of the mounting seat 3, and the plurality of clamping parts 331 extend downward away from one end of the mounting seat 3 to form an insertion end 332, and a protruding clamping block 333 is provided on the outer side surface of the insertion end 332.

[0024] From the above description, it can be seen that the beneficial effect of the utility model is that: the clamping portion 331 of the radiation unit assembly is used to be inserted into the assembly hole of the reflective plate until the clamping block 333 contacts the back of the reflective plate, so that the radiation unit assembly is plugged into the reflective plate to fix the radiation unit assembly on the reflective plate. The assembly process is convenient, the number of parts of the base station antenna is effectively reduced, the installation efficiency of the base station antenna is improved, and it is beneficial to the performance stability of the base station antenna.

[0025] Furthermore, the mounting seat 3 and the clamping portion 331 are an integrally formed one-piece structure.

[0026] It can be seen from the above description that the integrated structure can reduce the production and assembly processes, which is beneficial to improving the production efficiency of the radiation unit assembly.

[0027] Furthermore, the mounting base 3 includes a base 31, a support platform 32 and a plurality of support arms 33, the support platform 32 is arranged above the base 31, two ends of the plurality of support arms 33 are respectively connected to the base 31 and the support platform 32, and the base 31 is provided with the clamping portion 331.

[0028] It can be seen from the above description that a window is formed between two adjacent support arms 33, which is beneficial to improving the heat dissipation capacity of the radiation unit assembly.

[0029] Furthermore, the width of the insertion end 332 gradually decreases from one end close to the mounting seat 3 to the other end.

[0030] It can be seen from the above description that the structure of the insertion end 332 is more convenient for plugging and matching with the assembly hole of the reflector.

[0031] Furthermore, a window 334 is provided on the outer side surface of the insertion end 332 , and a protruding elastic arm 335 is provided on the inner circumference surface of the window 334 . The elastic arm 335 extends upward, and the block 333 is provided on the outer side surface of the elastic arm 335 .

[0032] It can be known from the above description that when the insertion end 332 is plugged into the reflective plate, the elastic arm 335 will be elastically deformed so that the clamping block 333 can pass through the assembly hole on the reflective plate.

[0033] Furthermore, the top end of the elastic arm 335 extends upward to form a pressing portion 336 .

[0034] From the above description, it can be seen that the pressing part 336 is exposed at the assembly hole of the reflective plate. By applying force to the pressing part 336, the elastic arm 335 is bent and deformed inward, so that the block 333 can pass through the assembly hole of the reflective plate, thereby facilitating the disassembly and assembly process of the radiation unit assembly on the reflective plate.

[0035] Furthermore, the feeding base plate 1 is provided with an avoidance hole 11 for the clamping portion 331 to pass through.

[0036] It can be seen from the above description that the avoidance hole 11 is provided to allow the clamping portion 331 to pass through the feeding base plate 1, which is conducive to making the structure of the radiation unit assembly more compact and meeting the development trend of product miniaturization.

[0037] Furthermore, the clamping portion 331 is provided with an anti-foolproof column 337 , and the feeding base plate 1 is provided with an anti-foolproof notch 12 that cooperates with the anti-foolproof column 337 .

[0038] It can be seen from the above description that the cooperation between the fool-proof column 337 and the fool-proof notch 12 can enable the accurate assembly of the feed base plate 1 and the radiation unit, which is beneficial to improving the assembly efficiency.

[0039] Furthermore, a protruding portion 41 protruding outward is provided on the side of the feed plate 4 , and a slot 34 cooperating with the protruding portion 41 is provided on the bottom of the mounting seat 3 .

[0040] It can be seen from the above description that the cooperation between the protrusion 41 and the slot 34 can limit the relative position of the feeding plate 4 and the mounting seat 3, thereby improving the assembly accuracy.

[0041] Furthermore, a plurality of buckles 35 for fastening the radiation panel 2 are disposed on the top of the mounting seat 3 .

[0042] From the above description, it can be seen that using the buckle 35 to connect and fix the radiation panel 2 and the mounting base 3 can reduce the number of parts of the radiation unit assembly, improve the installation efficiency, and facilitate the performance stability of the radiation unit assembly.

[0044] Specifically, the two radiation units have the same shape and structure. The radiation panel 2 and the feed base plate 1 are rectangular.

Each mounting seat 3 is provided with four clamping parts 331, and the mounting seat 3 and the clamping parts 331 are an integrally formed one-piece structure. In this embodiment, the mounting seat 3 is preferably made of plastic material.

[0045] The mounting base 3 includes a base 31, a support platform 32 and a plurality of support arms 33. The support platform 32 is arranged above the base 31. The two ends of the plurality of support arms 33 are respectively connected to the base 31 and the support platform 32. The base 31 is provided with a clamping portion 331.
