Description

BACKGROUND OF THE INVENTION 1. Field of the Invention This application claims to claim Chinese Patent Application No. 201110297347.3, entitled "Antenna Unit, Antenna Device, and Method of Mounting Antenna", filed on September 28, 2011, to the Chinese Patent Office. Priority is hereby incorporated by reference in its entirety. TECHNICAL FIELD Embodiments of the present invention relate to the field of communication technologies, and more particularly, to an antenna unit, an antenna device, and a method of installing an antenna. BACKGROUND OF THE INVENTION The early product architecture of a wireless distributed base station system is generally a "RRU (Radio Remote Unit) + Antenna (Passive)" approach, which generally has three implementation forms. They are: (l) RRU is at the bottom of the tower, the antenna is on the tower, and the two are connected by cables; (2) RRU is on the tower, close to the antenna, installed at the bottom or behind the antenna, between the two Cable connection; (3) Semi-integrated mode, RRU directly on the antenna, blindly inserted or cabled with the antenna. For the semi-integrated mode of the RRU and the antenna, the RRU is usually directly behind the antenna. One of the antennas can carry one RRU module or multiple RRU modules. The RRU and the antenna are connected by cable or by blind plug connection. Both of these connection methods need to be waterproof. When the cable is connected, multiple RRU modules can be mounted on one antenna.

At present, the evolution direction of the product is the integration of the RF unit and the antenna, and the RF unit and the antenna are integrated into one body and installed and maintained as a whole. However, the overall installation and maintenance is difficult. Subsequent further evolution of the product is modular to support multi-band, multi-system sharing and on-site maintenance of the product.

AAS (Active Antenna System) refers to a system that integrates a base station antenna and an active unit into one module. Only one antenna can be installed during installation. In the existing integrated AAS architecture, the vibrator is usually equipped with a reflector, and the vibrator is assembled from the front to the reflector. In a modular or integrated AAS architecture, the vibrator carries a reflector, and the isolation and decoupling between the columns of antennas is primarily regulated by a reflector. The vibrators are always the same, because the reflectors are different and there is a difference between the various antennas. Nowadays, the installation resources of the antenna feeder system are in short supply, and the demand for the common site and the common antenna feeder system is strong. When single-frequency, dual-frequency, multi-frequency combination of surface applications (such as typical high and low frequency), the structure of the reflector is various. In the scenario where the application scenario changes, the reflector and all the vibrators and feed components of all frequency bands need to be removed and replaced as a whole, which is complicated and wasteful.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the integrated AAS architecture, the vibrator is provided with a reflector, and the isolation and decoupling between the columns of antennas is mainly adjusted by the reflector. The vibrators are always the same, because the reflectors are different, various antennas There is a difference between them. However, such design is not universal. For example, if the reflector is a high and low frequency combination design, the design complexity will increase under high and high frequency combinations.

In the embodiment of the invention, the antenna element and the radio frequency module form an independent antenna unit, which has universality.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic cross-sectional view of an antenna unit in accordance with an embodiment of the present invention. In the antenna unit 10 of Fig. 1, the actual scale is not drawn in accordance with the respective parts, and the other drawings are also the same, and therefore the present invention should not be limited to the ratios, dimensions, and the like shown in the drawings. The antenna unit 10 includes a vibrator reflection plate 11, an antenna element 12, and a radio frequency module 13.

The vibrator reflection plate 11 has a first surface si and a second surface s2 opposite to the first surface si. The first surface si of the vibrator reflection plate 11 is made of a conductive material.

The antenna element 12 is disposed on the first surface si of the vibrator reflection plate 11 and is electrically connected to the first surface si.

The radio frequency module 13 is disposed on the second surface s2 of the vibrator reflection plate 11 and electrically connected to the antenna element 12.

In the embodiment of the present invention, the antenna element and the radio frequency module are combined into an independent antenna unit, so that the antenna unit can be adapted to different application scenarios, and the antenna unit can be easily and flexibly assembled with other components for different frequency bands or system combinations, thereby improving the antenna configuration and The efficiency of the installation.

It will be understood that in the present invention, "connected" or "electrically connected" may mean not only that the two are directly connected, but also that the two are connected by one or more intermediate devices. "Installation" in the present invention may include any existing installation method. For example, one component can be secured over, under or in another component by means of connectors (e.g., bolts, rivets, etc.) and/or adhesives. These understandings are all within the scope of embodiments of the invention.

In addition, the number of the vibrator reflection plate 11, the antenna element 12, or the radio frequency module 13 in the antenna unit 10 can be adjusted according to actual needs, and is not limited to the number shown in the figure. For example, one radio frequency module 13 may correspond to two or more antenna elements 12.

Alternatively, as an embodiment, the vibrator reflection plate 11 may be a flat plate as shown in FIG. Shape. However, embodiments of the invention are not limited thereto. The vibrator reflection plate 11 may include a side wall plate. The side wall plates are located on the first surface si of the vibrator reflection plate 11. The inner side of the side wall panel is made of a conductive material. The side wall panels can be implemented to surround or semi-enclose the antenna element 12 according to actual needs, for example, on one side, two sides, three sides or four sides of the antenna element 12.

Alternatively, as another embodiment, the vibrator reflector 11 is used alone or together with the main reflector of the antenna device to form a convergent beam. For example, the vibrator reflection plate 11 may be a printed circuit board (PCB). The first surface si of the vibrator reflection plate 11 is provided with a conductive material such as copper. The vibrator reflection plate 11 is coupled with the main reflection plate of the antenna device, for example. A capacitive coupling or a tight conductive coupling is formed.

In the case where the vibrator reflection plate 11 separately forms a convergent beam, the antenna unit 10 can be mounted through the support frame. In addition, a radome may also be mounted on the support frame to form an antenna device. For example, the support frame can be a square frame on which the antenna unit 10 and/or the antenna cover are mounted.

In the case where the vibrator reflection plate 11 and the main reflection plate of the antenna device form a convergent beam, the main reflection plate can function as a support skeleton alone. Alternatively, the primary reflector can be mounted to a separate support frame and the antenna unit 10 and/or radome can then be mounted to the primary reflector or support frame.

Alternatively, as another embodiment, a feed network may be disposed on the second surface s2 of the vibrator reflection plate 11. The feed network can include at least one of a power splitter, a combiner, a coupler, and a phase shifter. These devices can be integrated to reduce cable routing and reduce insertion loss.

Optionally, as another embodiment, the radio frequency module 13 may include two types of active modules or passive modules, and may also be divided into multiple frequency bands and standards. For example, one radio frequency module 13 may be dedicated to a specific frequency band or standard. .

In addition, in FIG. 1 and other drawings below, the shape of the antenna element is only schematic, and the embodiment of the present invention is not limited thereto. According to the requirements of different frequencies or standards, the corresponding antenna oscillator can be used. These variations are all within the scope of embodiments of the invention. Figure 2 is a schematic cross-sectional view of an antenna device in accordance with one embodiment of the present invention. The antenna device 20 of FIG. 2 includes an antenna unit 21, a main reflector 22, and a radome 23.

Among them, the main reflector 22 of Fig. 2 is an optional component. In the case where the vibrator reflection plate of the antenna unit 21 can separately form a convergent beam, the main reflection plate 22 can be eliminated. For convenience of description, the following description will be made with the case where the antenna device has a main reflector.

Only one opening of the main reflector 22 and one antenna unit 21 mounted through the opening are depicted in Fig. 2, but the embodiment of the invention is not limited thereto. The main reflector 22 of the embodiment of the present invention may be provided with at least one opening through which the at least one antenna unit 21 is detachably mounted. The number of openings on the main reflector 22 and the number of antenna elements 21 may be the same or different depending on actual needs.

The surface of the main reflection plate 22 is made of a conductive material. For example, the main reflection plate 22 may be entirely made of an aluminum plate, or a metal coating may be plated on the surface of the main reflection plate 22.

The radome 23 may be integrally or detachably mounted together with the main reflector 22. For example, when one or more antenna elements 21 are detachably mounted through one or more openings from a side of the main reflector 22 facing the radome 23 (hereinafter referred to as the front surface of the main reflector 22), The radome 23 can be detached from the main reflector 22 to mount the antenna unit 21. Alternatively, when one or more antenna units 21 are detachably mounted through one or more openings from the side of the main reflector 22 facing away from the radome 23 (hereinafter referred to as the back surface of the main reflector 22), The radome 23 and the main reflector 22 may be integrated or may be detachably mounted together without affecting the mounting of the antenna unit 21.

As shown by the broken line in Fig. 2, the antenna unit 21 is an example of the antenna unit 10 of Fig. 1, and therefore like parts will be denoted by like reference numerals, and the detailed description will be omitted as appropriate. In the embodiment of Fig. 2, the antenna unit 21 includes a vibrator reflection plate 11a, an antenna element 12a, and an RF module 13a. The vibrator reflecting plate 11a may be in the form of a flat plate, and may be, for example, a PCB. The first surface sla of the vibrator reflection plate 11a is coated with a conductive material (for example, copper) as a ground.

In the embodiment of FIG. 2, the length and width of the vibrator reflection plate 11a of the antenna unit 21 can be large. It is equal to or equal to the length and width of the opening on the main reflector 22. The antenna unit 21 further includes an insulating film 14 disposed on the first surface sla of the vibrator reflection plate 11a. For example, the insulating film 14 may be green oil overlying the first surface sla. The thickness of the insulating film 14 can be adjusted according to actual needs, for example, greater than 0 and less than or equal to 2 mm, but the embodiment of the present invention is not limited to the numerical examples given herein.

Through the insulating film 14, as shown in FIG. 2, after the antenna unit 21 is mounted in the opening of the main reflection plate 22, the main reflection plate 22 forms a capacitive coupling with the vibrator reflection plate 11a of the antenna unit 21, thereby being on the main reflection plate 22 and A radio frequency connection is formed between the antenna elements 12a, and a converged beam is formed by means of the main reflection plate 22.

In the embodiment of Fig. 2, the vibrator reflection plate 11a of the antenna unit 21 and the main reflection plate 22 are separated by an insulating film 14, but the embodiment of the invention is not limited thereto. In another embodiment, the insulating film 14 may be replaced by air, that is, the vibrator reflection plate 11a of the antenna unit 21 and the main reflection plate 22 are separated by a gap, and may also be in the vibrator reflection plate 11a and the main reflection plate 22. A capacitive coupling is formed between them. The width of the gap can be set according to actual needs (for example, considering assembly tolerances, electrical specifications, etc.). In this case, the insulating film 14 is not required.

When a plurality of antenna elements are included in the antenna device, means for adjusting coupling or isolation between the arrays and/or the vibrators may be provided on the main reflector 22, such as the riser portion of the main reflector shown in FIG. twenty four.

Alternatively, as another embodiment, a feed network is disposed on the second surface s2a of the vibrator reflection plate 11a. The feed network can include at least one of a power splitter, a combiner, a coupler, and a phase shifter. These devices can be integrated to reduce cable routing and reduce insertion loss.

Fig. 3 is a schematic cross-sectional view showing an antenna device according to another embodiment of the present invention. The antenna device 30 of Fig. 3 also does not require the insulating film 14, and the other portions are the same as those of Fig. 2, and therefore the same reference numerals are used.

As shown in Fig. 3, after the antenna unit 21 is mounted in the opening of the main reflection plate 22, the main reflection plate 22 is fitted to the vibrator reflection plate 11a of the antenna unit 21 to form a conductive coupling.

In the embodiment of Fig. 3, the first surface sla of the vibrator reflection plate 11a and the main reflection plate 22 are made of a conductive material, and the two are in close contact. For example, by bolts, rivets, glues, etc. Alternatively, either the first surface sla and the upper surface of the main reflector 22 are sufficiently flat so that the first surface sla and the main reflector 22 are bonded together, and a good conductive coupling is formed, so that the main reflector 22 and the vibrator reflect The boards 11a are used together to form a converged beam.

Other configurations of the antenna device 30 can be referred to Fig. 2, and therefore will not be described again.

Fig. 4 is a schematic cross-sectional view showing an antenna device according to another embodiment of the present invention. The antenna device 40 of Fig. 4 includes an antenna unit 41, a main reflector 42 and a radome 43.

The configuration of the main reflector 42 and the radome 43 can be referred to the main reflector 22 and the radome 23 in Figs. 2 and 3, and therefore will not be described again.

The vibrator reflection plate lib of the antenna unit 41 includes a side wall plate 15. The side wall panel 15 is located on the first surface sib of the vibrator reflection plate lib and surrounds the antenna element 12b. The inner side of the side wall panel 15 is made of a conductive material. In one embodiment, the lower plate portion of the vibrator reflector lib and the side wall panel 15 may be integrally formed.

After the antenna unit 41 is mounted in the opening, the upper end of the side wall panel 15 is higher than or equal to the lower end of the main reflector 42. For example, the upper end of the side wall panel 15 may be flush with the upper surface of the antenna element 12b to protect the vibrator during transportation, and may also take into account electrical and structural design requirements, above or below the upper surface of the antenna element 12b. .

In the embodiment of Fig. 4, after the antenna unit 41 is mounted in the opening of the main reflection plate 42, the main reflection plate 42 is capacitively coupled with the vibrator reflection plate lib of the antenna unit 41. For example, as shown in Fig. 4, the vibrator reflection plate lib of the antenna unit 41 and the main reflection plate 42 are separated by a gap. The gap between the main reflector 42 and the side of the vibrator reflector lib can be designed according to the actual situation, for example, assembly tolerances, electrical specifications, etc. can be considered.

However, embodiments of the present invention are not limited thereto, and may be similar to the embodiment of Fig. 3 such that the main reflector 42 is attached to the vibrator reflection plate lib of the antenna unit 41 to form a conductive coupling.

Since the length and width dimensions of the vibrator reflection plate lib of FIG. 4 are smaller than the length and width dimensions of the opening of the main reflection plate 42, the antenna unit 41 can be attached from the back surface of the main reflection plate 42. At this time, the radome 43 and the main reflector 42 may be integrated or may be detachably mounted together. Alternatively, as another embodiment, if the size of the radio frequency module 13b allows, for example, the length and width dimensions of the radio frequency module 13b are smaller than the opening, the antenna unit 41 may also be mounted from the front surface of the main reflection plate 42. In this case, the length and width of the vibrator reflection plate lib may be smaller than the length and width of the opening of the main reflection plate 42, or may be greater than or equal to the length and width of the opening of the main reflection plate 42. The radome 43 is detachably mounted with the main reflector 42.

If the length and width dimensions of the vibrator reflector lib are greater than or equal to the length and width of the opening of the main reflector 42, the vibrator reflector lib and the main reflector 42 may be separated by a gap or an insulating film to form a capacitive coupling. Alternatively, the vibrator reflection plate 1 lb and the main reflection plate 42 may be bonded to each other to form a conductive coupling.

Therefore, the vibrator reflector 1 lb and the main reflector 42 together form a convergent beam, which has a regulating effect on beam convergence.

Similarly, in the case of a multi-column antenna combination application, a means for adjusting the coupling or isolation between the arrays and/or the vibrators may be provided on the main reflector 42.

5A to 5F are schematic views showing a part of an example of an antenna apparatus according to an embodiment of the present invention. In the schematic views of Figures 5A-5F, the various portions are not drawn to scale. In addition, the coupling between the vibrator reflector and the main reflector can be referred to any of the above Figures 2 to 4, or a combination thereof.

Specifically, Figs. 5A and 5B are examples of multi-frequency (e.g., tri-band), and Figs. 5C and 5D are examples of dual-frequency, and examples of single-frequency of Figs. 5E and 5F. However, the embodiments of the present invention are not limited to these specific examples, and different frequency bands or combinations of standards can be realized according to requirements, and the antenna unit and the main reflector/radome are assembled flexibly, conveniently, and quickly. Thereby, the platform of the active and passive RF modules is realized, and the radome and the main reflector can also be platformized according to the requirements of high-frequency, high-low and high-surface combination.

601. The antenna element is disposed on the first surface of the vibrator reflector such that the antenna element is electrically connected to the first surface. Wherein the first surface and the second surface of the vibrator reflector are opposite each other, and the first surface of the vibrator reflector is made of a conductive material.

602. The radio frequency module is disposed on the second surface of the vibrator reflector such that the radio frequency module is electrically connected to the antenna vibrator to form an antenna unit including the vibrator reflector, the antenna vibrator, and the radio frequency module.

For example, the antenna unit 10 shown in Fig. 1, the antenna unit 21 shown in Figs. 2 to 3, or the antenna unit 41 shown in Fig. 4 is formed. To avoid repetition, it will not be described in detail.

7 is a flow chart of a method of installing an antenna device according to another embodiment of the present invention. The difference between Fig. 7 and Fig. 6 is that the antenna device mounted by the method of Fig. 7 requires a main reflector.

Steps 701-702 of Figure 7 are similar to steps 601-602 of Figure 6, and therefore will not be described in detail. However, steps 701-702 of Figure 7 may be performed once or more times to provide at least one antenna unit.

703. The at least one antenna unit is detachably mounted through at least one opening provided on the main reflector.

For example, after the at least one antenna unit is mounted in the opening, the main reflector forms a capacitive coupling or a conductive coupling with the vibrator reflector of at least one antenna unit, such as shown in Figures 2-4.

When the main reflection plate is capacitively coupled to the vibrator reflection plate of the at least one antenna unit, the sky may be disposed on the first surface of the vibrator reflection plate of the antenna unit. The gap and the thickness of the insulating film can be designed according to actual needs.

Optionally, as an embodiment, when installing at least one antenna unit, the side of the radome facing the radome (ie, the front side of the main reflector) or the side of the main reflector facing away from the radome (ie, the main The back side of the reflector) is detachably mounted to the antenna unit through the opening. E.g, In the case where the antenna unit is detachably mounted through the opening from the side of the main reflector facing away from the radome, the main reflector may be integrally or detachably mounted together with the radome. Further, in a case where one or more antenna units are detachably mounted through one or more openings from the side of the main reflector facing the radome, the main reflector and the radome are detachably mounted together.

In the embodiment of the invention, the antenna element and the radio frequency module are combined into an independent antenna unit, which is decoupled from the main reflector and the radome, so as to adapt to different application scenarios, the antenna unit can be easily and flexibly assembled with the main reflector for different The frequency band or standard combination improves the efficiency of antenna configuration and installation.

Fig. 8 is a schematic view showing an example of mounting an antenna device. In the embodiment of Fig. 8, at least one antenna unit is mounted from the back side of the main reflector (as indicated by the arrow in Fig. 8).

As shown in FIG. 8, at least one antenna unit 81 may be an antenna unit provided in the embodiment of FIG. 6 or FIG. 7, for example, may include the antenna unit 10 shown in FIG. 1, and the antenna unit 21 shown in FIG. And one or more of the antenna units 41 shown in FIG.

The main reflection plate 82 may be the main reflection plate shown in Figs. Only the back side of the main reflector 82 (the side facing away from the radome) is shown in FIG. Since the antenna unit 81 is mounted from the rear surface of the main reflection plate 82, the radome can be integrated with the main reflection plate 82 or can be detachably mounted together.

The main reflector 82 has at least one opening 83 therein. At the time of installation, the respective antenna units 81 are respectively installed through the openings 83. The number of openings 83 and the number of antenna elements 81 may be the same or different, for example, the number of openings 83 may be greater than or equal to the number of antenna elements 81.

The antenna device may include other mounting members to fasten the antenna unit 81 and the main reflector 82. Therefore, in the embodiment of the present invention, the antenna element is separated from the reflector, the antenna element and the RF module are integrated into one unit, and the main reflector and the radome are combined into another unit, and the two units are different according to different application scenarios and/or different frequency bands. The combination can be assembled freely, conveniently and quickly to realize AAS modularization.
