The antenna comprises a radiation unit, a phase shifter for adjusting the downward inclination angle of the antenna and a feed network, wherein the radiation unit is connected with the phase shifter through the feed network, so that the downward inclination angle of the antenna can be adjusted by moving a dielectric plate in the phase shifter.
The traditional phase-shifting feeder device is formed by connecting an independent phase shifter with a feed network circuit board through a cable. Therefore, the phase-shifting feed device has the disadvantages of more parts, more welding spots and long production time, and the phase-shifting feed device has large volume and heavy weight, which is not beneficial to the miniaturization and light weight of the antenna. Based on this, the present application provides an antenna and a phase-shift feeding device to solve the foregoing problems.
As shown in fig. 1 and 2, in one embodiment, a phase-shift feeding apparatus is provided, which includes a cavity structure and a feeding network board 200.
The cavity structure includes a dielectric substrate 100, a ground layer 120 and a phase shift circuit layer 130, wherein the dielectric substrate 100 has a strip-shaped slot 110, the ground layer 120 is disposed on the dielectric substrate 100, and the phase shift circuit layer 130 is disposed in the strip-shaped slot 110 and is insulated from the ground layer 120.
The feed network board 200 is used for closing the strip-shaped slot 110, the feed network board 200 includes a substrate, a conductive shielding layer 220 disposed on one surface of the substrate, and a feed circuit layer 210 disposed on the other surface of the substrate, the conductive shielding layer 220 is disposed toward the strip-shaped slot 110, the conductive shielding layer 220 and the ground layer 120 cooperate to form a shielding cavity 300 accommodating the phase shift circuit layer 130, the conductive shielding layer 220 and the phase shift circuit layer 130 are disposed in an insulating manner, and the feed circuit layer 210 is electrically connected to the phase shift circuit layer 130.
When the phase-shifting feed device is used, the dielectric substrate 100 can be obtained by injection molding, three-dimensional printing, machining and the like, then the ground layer 120 and the phase-shifting circuit layer 130 are formed at the preset position on the dielectric substrate 100 by using the processes of electroplating, chemical plating or Laser-Direct-Structuring (LDS), and the like, and then the feed network board 200 is fixed on the dielectric substrate 100, so that the conductive shielding layer 220 is matched with the ground layer 120 to form the shielding cavity 300 accommodating the phase-shifting circuit layer 130, a phase-shifting cavity is obtained, the conductive shielding layer 220 is insulated from the phase-shifting circuit layer 130, and the feed circuit layer 210 is electrically connected with the phase-shifting circuit layer 130. Thus, the feeding of the phase shift circuit layer 130 and the feeding circuit layer 210 is realized without using a cable, so that the assembling parts are simplified, the production efficiency is improved, and the whole volume and weight of the phase shift feeding device are reduced.
Further, it is understood that the weight of the dielectric substrate 100 is smaller than that of the metal case for the same volume, which is advantageous for reducing the weight of the phase shifter. In addition, the phase shift circuit layer 130 is not required to be formed by a substrate, and under the same condition, the thickness space of the substrate and the corresponding mounting structure can be eliminated, so that the volume of the phase shifter formed by the cavity structure is smaller.
Furthermore, the installation space of the antenna is smaller and smaller at present, the phase-shifting feeding device scheme is beneficial to reducing the weight and the volume of the antenna, and has great significance for correspondingly completing or accelerating the construction of the 4G or/and 5G antenna. The reduction of weight inevitably brings convenience to antenna installation, reduces the burden on an antenna installation area, and particularly reduces the burden on an iron tower. And the volume is reduced, so that the 4G or/and 5G antenna can be installed in a limited space, the coverage of the 4G or/and 5G antenna in the area is realized, the antennas in other frequency bands do not need to be adjusted or dismantled, and the debugging time is greatly saved.
The "ground layer 120" is a conductive layer as long as it can perform a grounding function. In particular a metal conductive layer, which may further be formed by electroplating, electroless plating or LDS, etc. integrated onto the housing. Of course, the adhesive coating layer having conductive property may be used, and is not limited thereto as long as it can be realized in the related art.
The material of the "dielectric substrate 100" may be any insulating material that can meet the requirements, including but not limited to plastic, as long as the dielectric constant meets the requirements of use.
In addition, the phase shift circuit layer 130 is disposed inside the shielding cavity 300, and the feeding circuit layer 210 is disposed outside the shielding cavity 300, so that the phase shift circuit layer 130 and the feeding circuit layer 210 are not interfered with each other, which is beneficial to avoiding the influence on the radiation performance of the radiation unit due to mutual coupling.
The phase shift circuit layer 130 is matched with the shielding cavity 300 to form a phase shifter module, and the function of a phase shifter can be realized. Therefore, compared with the conventional phase shifter, the cavity structure is more compact, and the cavity structure of the phase shifter is formed by using the dielectric substrate 100 (the weight is greatly reduced compared with the weight of a metal shell), the ground layer 120 and the shielding plate, so that the weight can be significantly reduced, and the function of the phase-shifting feed device can be ensured not to be affected.
Alternatively, as shown in fig. 1, in an embodiment, the stripe-shaped groove 110 penetrates at least one end of the dielectric substrate 100, so as to facilitate the entry and exit of the phase-shifting dielectric plate 400.
In any of the above embodiments, as shown in fig. 1 and 4, in an embodiment, the ground layer 120 is disposed on an outer sidewall of the strip-shaped groove 110. At this time, the phase shift circuit layer 130 may be disposed at any position of the inner wall of the stripe groove 110, and the phase shift circuit layer 130 may be formed by using two sidewalls of the stripe groove 110, which is beneficial to reducing the volume of the dielectric substrate 100.
In addition, the ground layer 120 is disposed outside the stripe slot 110, which is also beneficial to reducing the manufacturing difficulty and better surrounding the phase shift circuit layer 130.
Of course, in other embodiments, as shown in fig. 2, the ground layer 120 includes a first ground layer 122 disposed in the stripe slot 110 and a second ground layer 124 disposed outside the stripe slot 110, the second ground layer 124 is electrically connected to the first ground layer 122, the second ground layer 124 is disposed opposite to the phase shift circuit layer 130, and the phase shift circuit layer 130 is disposed in an insulating manner from the first ground layer 122. Thus, the phase shift circuit layer 130 can be surrounded by the first ground layer 122 and the second ground layer 124.
It is understood that the first ground layer 122 and the second ground layer 124 are disposed on different inner and outer sides of the slot 110, and can be flexibly combined according to the position of the phase shift circuit layer 130. Thus, compared to the conventional phase shift circuit board, the phase shift circuit layer 130 can be disposed at any position in the strip-shaped slot 110, and only the first ground layer 122 and the second ground layer 124 are matched to surround the phase shift circuit layer 130.
In addition to the foregoing embodiments, in an embodiment, a first avoiding slot is disposed between the phase shift circuit layer 130 and the first ground layer 122. Thus, the phase shift circuit layer 130 and the first ground layer 122 are insulated by the first avoiding groove, and the flat cable can be preset to form an interval in the manufacturing process, so that the implementation is easy.
On the basis of any of the above embodiments, as shown in fig. 1, in an embodiment, the dielectric substrate 100 includes a dielectric body 140 protruding into the strip-shaped groove 110, and the phase-shift circuit layer 130 is disposed on the dielectric body 140.

The structure solves the problem of fixing the dielectric substrate 100 and the feed network board 200, realizes the feed connection of the phase shift circuit layer 130 and the feed circuit layer 210, simplifies the process and is beneficial to improving the assembly efficiency.
Further, the outer sidewalls of the convex bodies 150 are wrapped with conductive layers for forming the signal terminals 160. Thus, a welding layer can be formed along the periphery of the convex body 150, which can increase the contact area between the signal terminal 160 and the pad 212 of the feed circuit layer 210, thereby improving the reliability of the electrical connection between the phase shift circuit layer 130 and the feed circuit layer 210, and also being beneficial to improving the reliability of the fixation between the dielectric substrate 100 and the feed network board 200.
Optionally, in one embodiment, the dielectric body 140 is integrally formed with the dielectric substrate 100. Therefore, the assembling procedures can be reduced, and the production efficiency is improved.
Further, in an embodiment, the dielectric bodies 140 and the inner sidewalls of the strip-shaped grooves 110 are disposed at intervals to form a channel for moving the phase-shifting dielectric plate 400. Thus, the dielectric substrate 100 can be used to form a phase shifter, and further, the phase-shifting dielectric plate 400 moves in the channel and cooperates with the phase-shifting circuit layer 130 to adjust the downward tilt angle of the antenna.
The feeding network board 200 may also integrate other elements, such as feeding pins, etc.

Therefore, a plurality of cavities can be integrated by using the dielectric substrate 100 to form a plurality of groups of phase-shifting feed devices, which is beneficial to further reducing the volume of the antenna feed structure, and two adjacent phase-shifting feed devices share one side wall, which is beneficial to further reducing the weight of the antenna.
At least two phase-shifting power feeders can work in the same frequency band or different frequency bands.
