DETAILED DESCRIPTION

[0063] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0065] In a first aspect, an embodiment of the present disclosure provides a ceiling antenna, such as Figure 1 As shown, the ceiling antenna is a dual-polarized antenna, which may include a vertical polarization unit 1 and a horizontal polarization unit 2. The vertical polarization unit 1 includes a single-arm oscillator 11 and a reflective structure 12, and

[0066] The single-arm oscillator 11 and the reflective structure 12 are arranged opposite to each other. The reflective structure 12 has a first surface and a second surface arranged opposite to each other, and the first surface is closer to the single-arm oscillator 11 than the second surface. The horizontal polarization unit 2 is arranged on the side of the first surface. The horizontal polarization unit 2 includes a plurality of radiation structures 20, which are arranged on the side of the first surface of the reflective structure 12 away from the second surface, and are arranged at intervals along the circumference of the first surface.

[0067] Reference Figure 1 , the single-arm oscillator 11 in the vertical polarization unit 1 adopts a hollow cone-column structure, which may specifically include a hollow pyramid or a hollow circular cone structure, and the reflective structure 12 adopts a hollow pyramid structure, which may specifically include a hollow pentagonal pyramid, a hollow hexagonal pyramid, etc. By feeding the single-arm oscillator 11 and cooperating with the reflection of the reflective structure 12, the vertical polarization unit 1 can be used as an omnidirectional antenna. The radiation structure 20 in the horizontal polarization unit 2 may adopt a single-layer radiation patch, or a double-layer or multi-layer radiation patch. In the embodiment disclosed in the present invention, only the radiation structure 20 including a double-layer patch is used as an example for explanation. Among them, the double-layer patch includes a first patch 21 and a second patch 22, and the first patch 21 is farther away from the reflective structure 12 than the second patch 22. And the orthographic projections of the first patch 21 and the second patch 22 on the first surface of the reflective structure 12 at least partially overlap to achieve normal radiation of the antenna signal.

[0068] Continue to refer to Figure 1 The ceiling antenna further includes a plurality of connection structures 3 connecting the single-arm oscillator 11 and the reflective structure 12, and the plurality of connection structures 3 are arranged at intervals along the circumferential direction of the side surface of the single-arm oscillator 11. The cone top area of ​​the single-arm oscillator 11 is smaller than the cone top area of ​​the reflective structure 12, and the connection structure 3 includes an L-shaped connection structure 3, one end of the L-shaped connection structure 3 is fixed to the side surface of the single-arm oscillator 11 by screws, and the other end is fixedly connected to the cone top of the reflective structure 12 by screws.

[0069] In some examples, the ceiling antenna further includes a mounting screw disposed on the second surface side of the reflective structure 12, the mounting screw passing through the cone top of the reflective structure 12 and connected to the single-arm oscillator 11. The mounting screw can be connected to a coaxial cable, which includes an insulating sheath, a conductive shielding layer, an insulating layer, and a conductive core wire from the outside to the inside. The signal is transmitted to the single-arm oscillator 11 and the reflective structure 12 through the coaxial cable, and radiated outward in the form of electromagnetic waves.

[0070] In particular, the ceiling antenna further includes a plurality of fixing components 4, which are arranged corresponding to the radiation patch. The fixing component 4 includes a first fixing component 41 and a second fixing component 42, the first patch 21 and the second patch 22 are fixedly connected through the first fixing component 41, and the reflective structure 12 and the first fixing component 41 are fixedly connected through the second fixing component 42, that is, the first patch 21, the second patch 22 and the reflective structure 12 are fixedly connected through the first fixing component 41 and the second fixing component 42, so as to improve the stability of the antenna and optimize the antenna's directional pattern.

[0071] The fixing component 4 in the embodiment of the present disclosure is described below with reference to specific examples.

[0072] The first example: Figure 1 As shown, the fixed component 4 in this example includes at least one sub-fixed component 40, and each sub-fixed component 40 includes a first fixed component 41 and a second fixed component 42. Among them, the first fixed component 41 includes a first connector 501 and a first support 511, and the second fixed component 42 includes a second connector 502 and a second support 512. The first connector 501 is reused as the second connector 502. The first support 511 is arranged between the first patch 21 and the second patch 22, and the second support 512 is arranged between the first patch 21 and the reflective structure 12. That is, the first patch 21, the second patch 22 and the reflective structure 12 are connected by the first connector 501, the first support 511 is used to maintain the spacing between the first patch 21 and the second patch 22, and the second support 512 is used to maintain the spacing between the second patch 22 and the reflective structure 12. At this time, the reflective structure 12 can be used as a reference ground for the radiation structure 20, and the medium between the reflection structure 12 and the radiation patch is air. In this case, using a double-layer radiation patch as a radiator can improve the gain and bandwidth of the antenna.

[0073] In some examples, the first connecting member 501 and the second connecting member 502 may include screws, and the first supporting member 511 and the second supporting member 512 may include nylon columns. Figure 2 As shown, the screws sequentially penetrate the first patch 21, the first nylon column, the second patch 22, the second nylon column and the reflective structure 12 to relatively fix the first patch 21, the second patch 22 and the reflective structure 12. A nut matching the screw is also provided between the second patch 22 and the reflective structure 12 to fix the position of the screw. The spacing between the first patch 21 and the second patch 22 can be adjusted by changing the height of the first nylon column, and the spacing between the second patch 22 and the reflective structure 12 can be adjusted by changing the height of the second nylon column. For example, Figure 2As shown, the ceiling antenna also includes a feed line 10 welded between the reflective structure 12 and the first patch 21. Properly increasing the height of the second nylon column can reduce the difficulty of welding and improve feasibility.

[0074] For example, multiple sub-fixing components 40 are usually provided to ensure the absolute fixation of the patch. At this time, at least part of the connecting lines of the multiple sub-fixing components 40 are not on the same straight line to ensure that the patch will not tilt and affect the antenna's directional pattern, such as Figure 3-5 In particular, in a low-cost production process, the fixing assembly 4 may include only one sub-fixing assembly, such as Figure 6-8 As shown, the sub-fixing component 40 is arranged at the center of the patch to ensure the relative fixation of the patch.

[0075] The second example: Fig. 9 As shown, the fixing component 4 in this example includes a first fixing component 41 and a second fixing component 42. The first fixing component 41 includes a fixing frame 6, and the second fixing component 42 includes a plurality of first connecting parts 9. Meanwhile, the first surface of the reflective structure 12 includes a plurality of mounting holes corresponding to the first connecting parts 9.

[0076] In some examples, the fixing frame 6 includes a first side wall 601 and a second side wall 602 that are arranged opposite to each other, and a first blind hole 621 and a second blind hole 622 are arranged on the first side wall 601. The first blind hole 621 is used to accommodate the first patch 21, and the second blind hole 622 is used to accommodate the second patch 22. The spacing between the first patch 21 and the second patch 22 can be adjusted by setting the height of the fixing groove in a direction perpendicular to the first surface of the reflective structure 12 and the position of the hole.

[0077] Exemplarily, the fixing frame 6 further includes a first window 61 penetrating the fixing frame 6 in a direction perpendicular to the first surface of the reflective structure 12 , and the first window 61 exposes at least a portion of the first patch 21 and the second patch 22 to ensure normal radiation process.

[0078] Optionally, the ceiling antenna further includes a feeder 10 welded between the reflective structure 12 and the second patch 22. In addition to the function of propagating electromagnetic waves, the feeder 10 also welds and fixes the reflective structure 12 and the second patch 22. In this way, the second patch 22 is fixed by the feeder 10 and the second blind hole 622 of the fixing frame 6 at the same time. At the same time, the fixing frame 6 also includes a first fixing plate 63 and a third connecting member 64 arranged on the side of the first blind hole 621 away from the reflective structure 12. The third connecting member 64 sequentially penetrates the fixing plate and the first patch 21 arranged in the first blind hole 621, so as to achieve the fixation of the first patch 21, as shown in FIG. Fig.10 shown.

[0079] In some examples, the third connector 64 may include a rivet.

[0080] In some examples, the first connecting portion 9 includes a buckle. The buckle includes a main body and two stoppers. The stoppers are arranged on the side of the main body, such as Fig.10 As shown. The bayonet cooperates with the mounting hole set on the reflective structure 12 to fix the radiation structure 20 and the fixing component 4 on the reflective structure 12 to ensure the stability of the antenna and optimize the gain and radiation pattern of the antenna. Optionally, by changing the height of the buckle, that is, changing the length of the main body, the distance between the fixing frame 6 and the reflective structure 12 can be adjusted, thereby adjusting the working space of the electric soldering iron when soldering the feed line 10 and reducing the difficulty of the operation. In addition, at least part of the connecting lines of the multiple buckles are not on the same straight line to prevent the fixing component 4 and the radiation structure 20 from tipping over to the left or right, affecting the antenna performance, such as Fig.11 shown.

[0081] The third example: Fig.12 As shown, the fixing assembly 4 in this example includes a first fixing assembly 41 and a second fixing assembly 42. The second fixing assembly 42 includes a second fixing plate 71 and a plurality of first connecting portions 9 arranged on a side of the second fixing plate 71 close to the reflective structure 12, and the first fixing assembly 41 includes a third side wall 701 and a fourth side wall 702 arranged opposite to each other on a side of the second fixing plate 71 away from the reflective structure 12. At the same time, the first surface of the reflective structure 12 includes a plurality of mounting holes arranged one-to-one corresponding to the first connecting portions 9.

[0082] In some examples, the second fixing plate 71 includes a first limiting groove 710 , and the first limiting groove 710 is used to accommodate the second patch 22 . The depth of the first limiting groove 710 is equal to the thickness of the second patch 22 .

[0083] In some examples, the second fixing plate 71 further includes a second window 711 penetrating the second fixing plate 71 in a direction perpendicular to the first surface of the reflective structure 12 , and the second window 711 exposes at least a portion of the second patch 22 to ensure normal radiation process.

[0084] In some examples, the third side wall 701 and the fourth side wall 702 include a first slide rail 7011 and a second slide rail 7021 that are relatively arranged, and the first slide rail 7011 and the second slide rail 7021 are adapted to the first patch 21 to accommodate the first patch 21. Optionally, the distance between the first patch 21 and the second patch 22 can be adjusted by setting the positions of the first slide rail 7011 and the second slide rail 7021. Specifically, the first slide rail 7011 and the second slide rail 7021 are fixed to the first patch 21 by a fourth connecting member 703. The fourth connecting member 703 may include glue. At this time, the first patch 21 is fixed to the first slide rail 7011 and the second slide rail 7021 by a glue dispensing process. Optionally, the second patch 22 can also be fixed to the second fixing plate 71 by glue, such as Fig.13 shown.

[0085] In some examples, the first connecting portion 9 includes a buckle. The buckle includes a main body and two stop parts. The stop parts are relatively arranged on the side of the main body. The buckle cooperates with the mounting hole set on the reflective structure 12 to fix the radiation structure 20 and the fixed component 4 on the reflective structure 12 to ensure the stability of the antenna and optimize the gain and radiation pattern of the antenna. Optionally, by changing the height of the buckle, that is, changing the length of the main body, the distance between the fixed frame 6 and the reflective structure 12 can be adjusted, thereby adjusting the working space of the soldering iron when soldering the feed line 10 and reducing the difficulty of the operation. In addition, at least part of the connecting lines of the multiple buckles are not on the same straight line to avoid the fixing component 4 and the radiation structure 20 from tipping over to the left or right, affecting the antenna performance, such as Fig.14 shown.

[0086] Compared with the second example, the third example reduces the size and material of the fixing component 4, and the first patch 21 does not need to be fixed with a hole. At the same time, the exposed area of ​​the first patch 21 is greatly increased, but the fixing effect is relatively reduced. Different designs can be made as needed during use.

[0087] The fourth example: Fig.15 As shown, the fixing assembly 4 in this example includes a first fixing assembly 41 and a second fixing assembly 42. The first fixing assembly 41 includes at least one fifth connecting member 80, such as Fig.15 As shown, the second fixing assembly 42 includes a third fixing plate 81 and a plurality of first connecting portions 9, as shown in FIG. Fig.16 At the same time, the first surface of the reflective structure 12 includes a plurality of mounting holes which are arranged in one-to-one correspondence with the first connecting portions 9 .

[0088] In some examples, the third fixing plate 81 includes a second limiting groove 810, and the second limiting groove 810 is used to accommodate the second patch 22. Fig.16 The depth of the second limiting groove 810 is equal to the thickness of the second patch 22 .

[0089] In some examples, the third fixing plate 81 further includes a third window 811 penetrating the third fixing plate 81 in a direction perpendicular to the first surface of the reflective structure 12, and the third window 811 exposes at least a portion of the second patch 22 to ensure the normal radiation process. Fig.16 shown.

[0090] In some examples, the fifth connecting member 80 includes a U-shaped member 801 and a first partition plate 8021 and a second partition plate 8022 disposed inside the U-shaped member 801. Fig.15 As shown. The U-shaped member 801 includes a first side plate 8011 and a second side plate 8012 that are arranged opposite to each other, and the first partition plate 8021 is closer to the first side plate 8011 than the second partition plate 8022. That is, the space defined by the first partition plate 8021 and the first side plate 8011 is used to fix the first patch 21, and the space defined by the second partition plate 8022 and the second side plate 8012 is used to fix the third fixing plate 81. Optionally, the width of the U-shaped member 801 and the positions of the first partition plate 8021 and the second partition plate 8022 can be set to adjust the distance between the first patch 21 and the second patch 22.

[0091] Optionally, the fixing assembly 4 may include a plurality of fifth connecting members 80 , which has better stability compared to the fixing assembly 4 including only one fifth connecting member 80 .

[0092] In some examples, the first connecting portion 9 includes a buckle. The buckle includes a main body and two stop parts. The stop parts are relatively arranged on the side of the main body. The buckle cooperates with the mounting hole set on the reflective structure 12 to fix the radiation structure 20 and the fixed component 4 on the reflective structure 12 to ensure the stability of the antenna and optimize the gain and radiation pattern of the antenna. Optionally, by changing the height of the buckle, that is, changing the length of the main body, the distance between the fixed frame 6 and the reflective structure 12 can be adjusted, thereby adjusting the working space of the soldering iron when soldering the feed line 10 and reducing the difficulty of the operation. In addition, at least part of the connecting lines of the multiple buckles are not on the same straight line to avoid the fixing component 4 and the radiation structure 20 from tipping over to the left or right, affecting the antenna performance, such as Fig.18 shown.

[0093] In a second aspect, an embodiment of the present disclosure provides an electronic device, wherein the electronic device includes a ceiling antenna, and the antenna includes the fixing component in any of the above embodiments.

[0094] In some examples, the antenna also includes a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filtering unit. The antenna in the communication device can be used as a transmitting antenna or a receiving antenna. Among them, the transceiver unit may include a baseband and a receiving end.

After the antenna in the communication system receives the signal, it can be processed by the filtering unit, the power amplifier, the signal amplifier, and the radio frequency transceiver and then transmitted to the receiving end in the transceiver unit. The receiving end may be, for example, a smart gateway.

[0095] Furthermore, the RF transceiver is connected to the transceiver unit, and is used to modulate the signal sent by the transceiver unit, or to demodulate the signal received by the antenna and transmit it to the transceiver unit. Specifically, the RF transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate the various types of signals provided by the baseband and then send them to the antenna. The antenna receives the signal and transmits it to the receiving circuit of the RF transceiver. The receiving circuit transmits the signal to the demodulation circuit, and the demodulation circuit demodulates the signal and transmits it to the receiving end.

[0096] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, and the signal amplifier and the power amplifier are connected to a filter unit, and the filter unit is connected to at least one antenna. In the process of sending signals in the communication system, the signal amplifier is used to improve the signal-to-noise ratio of the signal output by the RF transceiver and then transmit it to the filter unit; the power amplifier is used to amplify the power of the signal output by the RF transceiver and then transmit it to the filter unit; the filter unit may specifically include a duplexer and a filter circuit, and the filter unit combines the signals output by the signal amplifier and the power amplifier and filters out the clutter before transmitting them to the antenna, and the antenna radiates the signal. In the process of receiving signals in the communication system, the antenna receives the signal and transmits it to the filter unit, and the filter unit filters out the clutter from the signal received by the antenna and then transmits it to the signal amplifier and the power amplifier, and the signal amplifier amplifies the signal received by the antenna to increase the signal-to-noise ratio; the power amplifier amplifies the power of the signal received by the antenna. The signal received by the antenna is processed by the power amplifier and the signal amplifier and then transmitted to the RF transceiver, and the RF transceiver then transmits it to the transceiver unit.

[0097] In some examples, the signal amplifier may include various types of signal amplifiers, such as a low noise amplifier, which is not limited herein.

[0098] In some examples, the antenna provided by the embodiments of the present disclosure also includes a power management unit, which is connected to a power amplifier to provide the power amplifier with a voltage for amplifying a signal.
