In one embodiment, referring to fig. 1 to 7, a director 10 includes a metal guiding sheet 11 and a metal debugging branch 12. The metal guide piece 11 is provided above the vibrator 20. The number of the metal debugging branches 12 is more than two, the metal debugging branches 12 are electrically connected with the metal guiding sheet 11, and the metal debugging branches 12 and the metal guiding sheet 11 are located on different planes.

In the above-mentioned guiding device 10, the metal guiding sheet 11 is connected to the metal debugging branch 12, and the metal debugging branch 12 and the metal guiding sheet 11 are located on different planes. The impedance mismatch problem caused by the coupling between the units is counteracted by the parasitic effect between the metal guide sheet 11 and the vibrator 20, and the performance indexes such as standing waves, isolation, directional diagrams and the like are improved to a certain extent. Different from the conventional metal guiding sheet 11 with a two-dimensional structure, the above-mentioned director 10 adopts a three-dimensional structure, according to the microwave theory, the current amplitude and phase relationship of the parasitic unit relative to the excited unit depends on the tuning of the parasitic unit, a second resonance frequency can be generated by deriving the metal guiding sheet 11 with the conventional two-dimensional structure from a horizontal plane to a vertical plane, and the two resonance frequencies are brought close to each other by specifically adjusting the second resonance frequency, so that the wide bandwidth can be expanded, and the optimized adjustment of indexes and performance can be realized.

Specifically, the metal adjustment branches 12 are vertically disposed on the metal guide sheet 11, or the metal adjustment branches 12 are obliquely disposed on the metal guide sheet 11, and an angle a between the extending direction of the metal adjustment branches 12 and the surface of the metal guide sheet 11 is, for example, 0 ° to 90 °. The specific size of the included angle a is set according to actual requirements, so that the performance index of the antenna is optimized.

Please refer to fig. 3 and fig. 5, the shapes of the two or more metal debugging branches 12 connected to the same metal guiding sheet 11 may be the same or different, and the lengths may be the same or different, and are set according to the actual debugging requirements.

In one embodiment, referring to fig. 1 to 7, two or more metal debugging branches 12 are arranged around the circumference of the metal guiding sheet 11 at intervals. Specifically, the number of the metal adjustment branches 12 is four, and the four metal adjustment branches 12 are arranged at equal intervals around the circumferential direction of the metal guide piece 11. Therefore, the symmetry is good, the second resonant frequency is well adjusted, the two resonant frequencies are close to each other, the bandwidth can be widened, and the index and the performance can be optimally adjusted.

In one embodiment, referring to fig. 2 to 7, the metal debugging branches 12 are detachably mounted on the metal guiding sheet 11. Specifically, the outer edge of the metal guiding sheet 11 is provided with a convex portion 111 corresponding to the metal adjusting branch 12, and the metal adjusting branch 12 is provided with a first insertion hole 1211 corresponding to the convex portion 111. The convex portion 111 is inserted into the first insertion hole 1211, and the convex portion 111 is in interference fit or snap fit with the first insertion hole 1211. Therefore, the metal debugging branches 12 and the metal guiding sheets 11 are detachably combined, so that the metal debugging branches 12 with different shapes and lengths can be replaced according to debugging requirements, and the replacement operation of the metal debugging branches 12 is convenient.

It should be understood that, referring to fig. 2 to 7, the interference fit between the protrusion 111 and the first insertion hole 1211 means that the outer diameter of the protrusion 111 is slightly larger than the inner diameter of the first insertion hole 1211, so that the protrusion 111 is inserted into the first insertion hole 1211 to secure the protrusion 111 in the first insertion hole 1211, thereby facilitating the installation of the metal adjusting branch 12 on the metal guiding sheet 11. On the contrary, when external force is applied to the metal debugging branch 12, the metal debugging branch 12 can be conveniently pulled out from the metal guiding sheet 11, and the operation is convenient.

It can be understood that, correspondingly, the convex portion 111 and the first insertion hole 1211 are in snap fit, that is, the convex portion 111 is provided with a clamping portion, and the hole wall of the first insertion hole 1211 is provided with a clamping hole in snap fit with the clamping portion; or, the convex portion 111 is provided with a locking hole, and the hole wall of the first insertion hole 1211 is provided with a locking portion matching with the locking hole. Thus, the disassembly and assembly operation of the metal debugging branch knot 12 and the metal guiding sheet 11 can be conveniently and rapidly realized.

In one embodiment, referring to fig. 2 to 7, the metal debug branch 12 includes a first metal debug plate 121 and a second metal debug plate 122. One end of the first metal debugging plate 121 is connected to the metal guiding sheet 11, and the other end of the first metal debugging plate 121 is rotatably connected to one end of the second metal debugging plate 122. Wherein, the face of first metal debugging board 121 and the face that the metal leads to piece 11 parallel or be in the coplanar, the face of second metal debugging board 122 then can rotate for the face that leads to the piece, the face of second metal debugging board 122 is different for the performance index of the antenna that corresponds when the face that leads to the piece rotates different contained angles a position, just also rotate second metal debugging board 122 according to the debugging demand and make second metal debugging board 122 rotate and predetermine the angle, the debugging operation is comparatively convenient, debugging efficiency can improve greatly. The adjustment of the antenna resonant frequency (i.e. the working frequency) can be realized without adjusting the size and the shape (usually adjusted to be round or square) of the structure of the metal guide sheet 11 and the height of the distance element 20 as the traditional two-dimensional structure.

In one embodiment, referring to fig. 2 to 7, the first metal debugging plate 121 is connected to the second metal debugging plate 122 through a damping rotating shaft 123. So, according to the requirement of antenna performance index, when rotating second metal debugging plate 122 to predetermined angular position, can realize under the effect of damping pivot 123 that the contained angle between second metal debugging plate 122 and the first metal debugging plate 121 keeps invariable to need not to realize with the help of external equipment that relatively fixed between second metal debugging plate 122 and the first metal debugging plate 121, the debugging operation is comparatively convenient, and work efficiency can improve greatly. Of course, as an alternative, the damping rotating shaft 123 is not used to connect the first metal debugging plate 121 and the second metal debugging plate 122, and other adjusting parts may be used to cooperate with a common rotating shaft to achieve the mutual assembly of the first metal debugging plate 121 and the second metal debugging plate 122.

In one embodiment, referring to fig. 2 to 7, the metal debugging branch 12 further includes a metal extension plate 124 detachably connected to the second metal debugging plate 122. So, on the one hand, after second metal debugging board 122 connects metal extension board 124, metal extension board 124 can the corresponding length that increases metal debugging minor matters 12 to can realize debugging the performance index of antenna, the debugging operation is comparatively convenient, has better regulating effect to second resonant frequency, makes two resonant frequency be close to each other, just so can expand wide bandwidth, realizes the optimization of index and performance and adjusts. On the other hand, the metal debugging minor matters 12 with different shapes and lengths can be replaced according to debugging requirements, and the replacement operation of the metal debugging minor matters 12 is more convenient.

The metal extension plate 124 is in interference fit or snap fit with the second socket 1221. Therefore, the metal extension plate 124 and the second metal debugging plate 122 can be quickly disassembled and assembled, and the debugging work efficiency is high.

It is understood that the interference fit of the metal extension plate 124 with the second socket 1221 means that the outer diameter of the metal extension plate 124 is slightly larger than the inner diameter of the second socket 1221, so that the metal extension plate 124 can be fastened in the second socket 1221 after the metal extension plate 124 is inserted into the second socket 1221, and thus the metal extension plate 124 can be conveniently installed in the second socket 1221. On the contrary, when an external force is applied to the metal extension plate 124, the metal extension plate 124 can be easily pulled out from the second insertion hole 1221, so that the operation is convenient.

It can be understood that, if the metal extension plate 124 is in snap fit with the second insertion hole 1221, the corresponding means is that the metal extension plate 124 is provided with a clamping portion, and the hole wall of the second insertion hole 1221 is provided with a clamping hole in snap fit with the clamping portion; or the metal extension plate 124 is provided with a clamping hole, and the hole wall of the second insertion hole 1221 is provided with a clamping portion matched with the clamping hole. Thus, the metal extension plate 124 and the second metal debugging plate 122 can be conveniently and quickly disassembled.

As an alternative, the performance index of the antenna may be adjusted by reducing the length of the metal extension plate 124.

As an alternative, the length of the metal commissioning stubs 12 may be telescopically adjustable. Specifically, the length of the metal extension plate 124 or the second metal debugging plate 122 can be telescopically adjusted. Therefore, when the lengths of the metal debugging branches 12 are different, the performance index of the antenna can be adjusted correspondingly.

In the base station antenna, the metal guiding sheet 11 is connected to the metal debugging minor matters 12, and the metal debugging minor matters 12 and the metal guiding sheet 11 are located on different planes. The impedance mismatch problem caused by the coupling between the units is counteracted by the parasitic effect between the metal guide sheet 11 and the vibrator 20, and the performance indexes such as standing waves, isolation, directional diagrams and the like are improved to a certain extent.

The antenna not only guarantees the radiation pattern index, but also gives consideration to circuit standing waves and isolation indexes, and is very suitable for being used in a complex antenna structure environment (such as an arc antenna housing or a multi-frequency mutual coupling oscillator 20 array).
