[0025] 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.

[0026] Please refer to Figures 1 to 3 A radiation unit component includes a mounting bracket 1, a feeding base plate 2, a radiation panel 3, two feeding plates 4 and at least one parasitic body 5; the two feeding plates 4 are orthogonally arranged, the top ends of the two feeding plates 4 are respectively connected to the radiation panel 3 for feeding, and the bottom ends of the two feeding plates 4 are respectively connected to the feeding base plate 2 for feeding; the mounting bracket 1 includes a mounting seat 11 and a plurality of support bars 12 arranged on the mounting seat 11, and the parasitic body 5 can be detachably mounted on the support bars 12; a protruding plug-in column 13 is provided at the bottom of the mounting seat 11, and at least one elastic clamping arm 131 is provided on the side of the plug-in column 13, and a socket 31 cooperating with the plug-in column 13 is provided on the radiation panel 3.

[0027] From the above description, it can be seen that the beneficial effect of the utility model is that when the mounting bracket 1 of the radiation unit assembly is assembled with the radiation panel 3, the plug-in column 13 of the mounting bracket 1 is aligned with the socket 31 of the radiation panel 3, and then the plug-in column 13 is inserted into the socket 31 until the elastic clamp arm 131 passes through the socket 31 and contacts the lower surface of the radiation panel 3 to complete the assembly. There is no need to use additional fasteners, the assembly process is simple and convenient, the installation efficiency is high, and it is beneficial to the performance stability of the base station antenna.

[0028] Furthermore, the mounting base 11 includes a main body 111 and an extending portion 112 formed by bending and extending a portion of the edge of the main body 111 downward, and the plug-in column 13 is disposed at the bottom end of the extending portion 112 .

[0029] From the above description, it can be seen that arranging the plug post 13 at the bottom end of the extension portion 112 can prevent the radiation panel 3 from being too close to the main body 111 of the mounting base 11, so that a larger cavity is formed between the main body 111 and the radiation panel 3, which is conducive to improving the heat dissipation capacity.

[0030] Furthermore, a stopper 113 protruding and extending outward is provided on the outer side surface of the extension portion 112 .

[0031] It can be seen from the above description that the stopper 113 can limit the relative position of the mounting seat 11 and the radiation panel 3, thereby improving the assembly accuracy.

[0032] Furthermore, multiple positioning protrusions 121 are provided on the outer sides of the multiple support bars 12 from top to bottom, and the parasite 5 is provided with multiple positioning openings 51. After each of the support bars 12 passes through the corresponding positioning openings 51, the parasite 5 is located on each of the positioning protrusions 121 at the same height position.

[0033] From the above description, it can be seen that the assembly method of the parasitic body 5 and the mounting seat 11 is simple, and the distance between the parasitic body 5 and the radiation panel 3 is adjusted according to different application situations, which effectively improves the impedance bandwidth and radiation bandwidth of the radiation unit component.

[0034] Furthermore, the support bar 12 includes an elastic section 122 and a positioning section 123 . The positioning section 123 is connected to the mounting seat 11 through the elastic section 122 . The positioning protrusion 121 is disposed on the corresponding positioning section 123 .

[0035] It can be seen from the above description that the elastic section 122 can cause the support bar 12 to undergo a certain degree of elastic deformation, so as to facilitate the assembly and disassembly of the parasite 5 on the support bar 12 .

[0036] Furthermore, a guiding inclined surface 1211 is disposed on the outer side surface of the positioning protrusion 121 , and the top end of the guiding inclined surface 1211 is inclined toward the direction approaching the supporting bar 12 .

[0037] It can be seen from the above description that providing the guiding inclined surface 1211 can facilitate the positioning opening 51 of the parasite 5 to be clamped between two adjacent positioning protrusions 121 .

[0038] Furthermore, the mounting seat 11, the support bar 12 and the positioning protrusion 121 are an integrally formed one-piece structure.

[0039] 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.

[0040] Furthermore, the number of the parasites 5 is two.

[0041] Furthermore, the number of the support bars 12 is four.
