[0038] Firstly, Figure 1 This is a perspective view of an omnidirectional indoor distribution antenna according to an embodiment of this disclosure; Figure 2 This is a top view of an omnidirectional indoor distribution antenna according to an embodiment of the present disclosure; Figure 3 This is a partial cross-sectional view of an omnidirectional indoor distribution antenna according to an embodiment of this disclosure; as shown... Figure 1-3As shown, this disclosure provides an omnidirectional indoor distributed antenna, which is a dual-polarized antenna that may include a vertical polarization unit 1 and a horizontal polarization unit 2. The vertical polarization unit 1 includes a single-arm dipole 11 and a reflective structure 12, with the dipole 11 and reflective structure 12 facing each other. The reflective structure 12 has a first surface and a second surface arranged opposite to each other, with the first surface closer to the dipole 11 than the second surface. The horizontal polarization unit 2 is disposed on the first surface side. The horizontal polarization unit 2 includes a plurality of radiating structures 21 located on the side of the first surface of the reflective structure 12 away from the second surface and spaced circumferentially along the first surface. Specifically, in this disclosure embodiment, the reflective structure 12 includes at least a first reflective component 121, which includes a plurality of main body portions 1211 arranged sequentially along its circumference. Each main body portion 1211 has a radiating structure 21 disposed on it; for example, the main body portion 1211 and the radiating structure 21 are arranged in a one-to-one correspondence. The radiating structure 21 includes at least one radiating patch, and the outer contour of the main body 1211 is adapted to the outer contour of the radiating patch. For example, the contour of the radiating patch is rectangular, and the contour of the main body 1211 is also rectangular, and the sides of the two are arranged in a one-to-one correspondence.

[0039] Reference Figure 1 , Figure 1Taking the single-arm dipole 11 in the vertical polarization unit 1 as an example, which adopts a conical structure, by feeding the single-arm dipole 11 and cooperating with the reflection of the reflection structure 12, the vertical polarization unit 1 can serve as a wide-bandwidth omnidirectional antenna. The radiating structure 21 in the horizontal polarization unit 2 can adopt a single-layer radiating patch or a double-layer radiating patch, that is, the horizontal polarization unit 2 can serve as a patch antenna, which has the characteristics of high gain and wide beam. In this embodiment of the disclosure, only the radiating structure 21 including a double-layer radiating patch is taken as an example. For ease of description, the one of the two radiating patches closer to the main body 1211 is referred to as the first radiating patch 201, and the other is referred to as the second radiating patch 202. In this embodiment, since the radiating structure 21 is disposed on the main body 1211, the main body 1211 serves as a reference electrode for the radiating structure 21. Simultaneously, the outer contours of the main body 1211 and the first radiating patch 201 / second radiating patch 202 located thereon are adapted to each other. That is, the distance between the edge of the main body 1211 and the edge of the first radiating patch 201 / second radiating patch 202 can be relatively reduced. Therefore, the high pitch angle (e.g., Theta ≥ 60°) gain of the horizontal polarization unit 2 can be improved, making the edge currents of the first radiating patch 201 and the second radiating patch 202 as symmetrical as possible, thereby improving the overall radiation pattern of the horizontal polarization unit 2. In this embodiment, taking the radiating structure 21 including the first radiating patch 201 and the second radiating patch 202 as an example, the spacing between the first radiating patch 201 and the second radiating patch 202 in each radiating structure 21 can be maintained by a fixing member. The first radiating patch 201 can be fixed to the main body 1211 by a support member. In this case, the main body 1211 serves as the reference electrode of the radiating structure 21, and the medium between the main body 1211 and the first radiating patch 201 is air. In this case, using a double-layer radiating patch as the radiator can improve gain and bandwidth. The support member can be a nylon pillar, plastic clip, etc., which will not be listed here. The fixing member and the support member can be made of the same material.

[0040] Of course, the first radiating patch 201 in the radiating structure 21 can also be disposed on the dielectric substrate and fixed on the main body 1211 by the dielectric substrate, wherein the dielectric substrate can be a PCB.

[0041] In one example, the orthographic projection of the second radiating patch 202 onto the plane of the main body 1211 lies within the orthographic projection of the first radiating patch 201 onto the plane of the main body 1211. In this case, the size of the first radiating patch 201 is larger than the size of the second radiating patch 202. In another example, the orthographic projection of the second radiating patch 202 onto the plane of the main body 1211 covers the orthographic projection of the first radiating patch 201 onto the plane of the main body 1211. In this case, the size of the first radiating patch 201 is smaller than the size of the second radiating patch 202. In the accompanying drawings of the embodiments of this disclosure, only the example of the first radiating patch 201 of each radiating structure 21 having a larger size than the second radiating patch 202 is used.

[0042] In some examples, the shapes of the first radiating patch 201 and the second radiating patch 202 may be the same or different. In the embodiments of this disclosure, the shapes of the first radiating patch 201 and the second radiating patch 202 can both be selected from circles, ellipses, polygons, or irregular shapes. When the shapes of the first radiating patch 201 and the second radiating patch 202 are polygons, their shapes can both be rectangles, squares, hexagons, trapezoids, etc. In the embodiments of this disclosure, only rectangular shapes of the first radiating patch 201 and the second radiating patch 202 are used as examples. It should be understood that the shape of the main body 1211 is also rectangular in this case.

[0043] In some examples, the horizontal polarization unit 2 in this embodiment of the present disclosure includes not only the radiation structure 21 described above, but also a plurality of feeding components 22 and a power divider network 23. The power divider network 23 has a first feeding port and a plurality of second feeding ports, and one second feeding port is electrically connected to a radiation structure 21 through a feeding component 22. In this case, the electromagnetic wave signal fed into the first feeding port of the power divider network 23 is fed into the feeding component 22 through the second feeding ports, and the feeding component 22 then feeds the electromagnetic wave signal into the radiation structure 21 for radiation.

[0044] Specifically, the power divider network 23 is a one-to-many power divider. For example, if the number of radiating structures 21 is 5, the power divider network is a one-to-five power divider, and the corresponding number of power supply components 22 is also 5. The one-to-five power divider has one main path and five branches. Both the main path and the branches have a first terminal and a second terminal. The first terminal of the main path is used as the first power supply port of the power divider network 23, and the second terminal of the main path is connected to the first terminal of each branch. The second terminal of each branch is used as the second power supply port.

[0045] The dielectric board of the one-to-many power divider can be made of PCB dielectric boards such as polytetrafluoroethylene, glass, and fiberboard.

[0046] In some examples, Figure 4This is a schematic diagram of the first coaxial cable of the omnidirectional indoor distribution antenna according to an embodiment of this disclosure; as shown... Figure 4 As shown, the power supply assembly 22 can be a first coaxial cable. The first coaxial cable includes a first core 221, a first dielectric layer 222, a first reference electrode layer 223, and a first protective layer 224 nested in sequence. The first coaxial cable includes a first connection end and a second connection end, as well as a first transmission segment connected between the first connection end and the second connection end. The first core 221 of the first connection end is electrically connected to the radiating structure 21, and the core of the second connection end is connected to a second power supply port. For the first connection end, in the direction from the first connection end to the second connection end, the first core 221, the first dielectric layer 222, the first reference electrode layer 223, and the first protective layer 224 are exposed in sequence. The first reference electrode layer 223 is electrically connected to the reflecting structure 1212. The portion of the first connection end exposing the first dielectric layer 222 extends from the second surface side of the reflecting structure 1212 to the first surface side through a first through-hole penetrating the reflecting structure 1212. The exposed core of the first connection end is electrically connected to the radiating structure 21, and the connection position is the power supply point of the radiating structure 21. Furthermore, the reflective structure 12 can be a ground electrode, and the first reference electrode layer 223 is connected to the reflective structure 12. In this case, the signal loaded on the first reference electrode layer 223 is a ground signal. The first reference electrode layer 223 and the reflective structure 12 can be connected by welding or screwing. Of course, without affecting the antenna performance, the first reference electrode layer 223 and the reflective structure 12 can be electrically connected in any way.

[0047] When the power supply assembly 22 uses a first coaxial cable, the first core 221 of the first coaxial cable is connected to the first radiating patch 201201, and the connection point is the power supply point. The operating frequency of the horizontal polarization unit 22 can be adjusted as needed by the spacing between the first radiating patch 201201 and the second radiating patch 202202 in the radiating structure 2121, their shapes and sizes, and the position of the power supply point, thereby realizing a high-gain, wide-beam horizontal polarization unit 2.

[0048] In some examples, the power divider network 23 is disposed on the side of the second surface of the reflective structure 12 facing away from the first surface. Since the reflective structure 12 is a conductive structure, an interlayer insulating layer is disposed between the second surface of the reflective structure 12 and the power divider network 23 to isolate them. In this embodiment, disposing the power divider network 23 on the second surface of the reflective structure 12 and isolating it from the reflective structure 12 by the interlayer insulating layer saves space and allows the reflective structure 12 to serve as a reference ground for the power divider network 23, thus simplifying the overall antenna structure.

[0049] In some examples, the vertical polarization unit 1 of this disclosure embodiment includes not only the single-arm oscillator 11 and the reflective structure 12 described above, but also a second coaxial cable for powering the single-arm oscillator 11. The structure of the second coaxial cable is the same as that of the first coaxial cable, that is, the second coaxial cable includes a second core, a second dielectric layer, a second reference electrode layer, and a second protective layer nested in sequence; the second reference electrode layer is electrically connected to the reflective structure 12, and the second core is connected to the single-arm oscillator 11 through a second via penetrating the reflective structure 12. In this case, the second reference electrode layer is connected to the reflective structure 12, that is, the signal of the second reference electrode layer is a ground signal, and there is no need to set a separate signal terminal for the second reference electrode layer. Moreover, most of the structure of the second coaxial cable is disposed within the conical disk structure of the reflective structure 12, thus saving space.

[0050] In some examples, continue to refer to Figure 1 The omnidirectional indoor distributed antenna in this embodiment includes not only the structure described above, but also a radome, with the vertical polarization unit 1 and the horizontal polarization unit 2 located inside the radome. Specifically, the radome may include a first part and a second part. The reflective structure 12 of the horizontal polarization unit 2 and the vertical polarization unit 1 is located in the first part, and the single-arm vibrator 11 of the vertical polarization unit 1 is located in the second part. The reflective structure 12 is fixed to the bottom plate of the first part of the radome, for example, by bolts. A limiting member is provided at the top of the second part of the radome to prevent the single-arm vibrator 11 from swaying and affecting antenna performance. In one example, the radome may be made of plastic resin material.

[0051] In some examples, regardless of the structure described above for the horizontal polarization unit 2 in this embodiment, the number of radiation structures 21 in the horizontal polarization unit 2 can be varied, such as three, four, five, or six. The examples above all use five radiation structures 21 as an example. In this embodiment, by reasonably setting the number of radiation structures 21, the gain can be effectively improved, and the circularity of the radiation pattern can be better.

[0052] The following description, in order to make the specific structure of the reflection structure 12 in the omnidirectional indoor antenna of the present disclosure embodiment clearer, as well as the correspondence between the reflection structure 12 and the radiation structure 21, will be provided in conjunction with specific examples.

[0053] First example: (Refer to) Figure 1 and 2In this example, the reflective structure 12 includes a first reflective component 121 and a second reflective component 122. The first reflective component 121 includes a plurality of main body portions 1211 and filling portions 1212 connected between the main body portions 1211. The second reflective component 122 is connected to the main body portions 1211 and is disposed opposite to the single-arm oscillator 11. The main body portions 1211 are rectangular, and the filling portions 1212 are triangular. The angle between the extended surface of the plane containing the main body portions 1211 and the extended surface of the plane containing the second reflective component 122 is a first dihedral angle, and the angle between the extended surface of the plane containing the filling portions 1212 and the extended surface of the plane containing the second reflective component 122 is a second dihedral angle. The first dihedral angle and the second dihedral angle are not equal. That is, the plane containing the main body portions 1211 and the plane containing the filling portions 1212 are not on the same plane. Both the main body 1211 and the first radiating patch 201 / second radiating patch 202 of the radiating structure 21 located thereon are rectangular. At this time, by adjusting the size of the first radiating patch 201 / second radiating patch 202, the distance between the first radiating patch 201 / second radiating patch 202 and the edge of the main body 1211 can be reduced. With corresponding arrangement, the edge currents of the first radiating patch 201 and the second radiating patch 202 can be made as symmetrical as possible, which can improve the overall radiation pattern of the horizontal polarization unit 2.

[0054] In some examples, the first dihedral angles formed by the extended surfaces of the planes containing each main body portion 1211 and the plane containing the second reflective component 122 are all equal. The second dihedral angles formed by the extended surfaces of the planes containing each filling portion 1212 and the plane containing the second reflective component 122 are all equal. This facilitates the structural design of the first reflective component 121. Furthermore, the dimensions of each main body portion 1211 and each filling portion 1212 can be designed to be the same.

[0055] In some examples, the main body 1211 and the first radiating patch 201 and the second radiating patch 202 located thereon are arranged in parallel. This facilitates powering the first radiating patch 201.

[0056] In some examples, Figure 5 This is a schematic diagram of the first reflective component 121 of a first example of an omnidirectional indoor distributed antenna according to an embodiment of this disclosure; as shown Figure 5 As shown, the first reflective component 121 also includes a plurality of connecting parts 1213 connected in sequence, one connecting part 1213 connecting one main body part 1211, and the connecting parts 1213 and the main body part 1211 are integral structures; each connecting part 1213 is a second reflective component 122.

[0057] In some examples, continue to refer to Figure 2The reflective structure 12 includes not only a first reflective component 121 and a second reflective component 122, but also a fixing component 123. The fixing component 123 is connected to the side of the first reflective component 121 away from the second reflective component 122 and is configured to be fixed to the base plate of the radome to achieve the fixation of the reflective structure 12 to the radome.

[0058] Specifically, the fixing component 123 may include a first fixing part 123a and a second fixing part 123b. The first fixing part 123a is connected to the main body part 1211, and the second fixing part 123b is connected to the filling part 1212. Both the first fixing part 123a and the second fixing part 123b are arc-shaped, and the line connecting the arcs of each first fixing part 123a and each second fixing part 123b forms a circle. Both the first fixing part 123a and the second fixing part 123b are disposed on the bottom plate of the radome and are fixedly connected to the bottom plate of the radome, for example, by means of screws, clips, etc. That is to say, the outer contour of the orthographic projection of the reflective structure 12 composed of the first reflective component 121, the second reflective component 122 and the fixing component 123 onto the plane where the bottom plate of the radome is located is circular.

[0059] by Figure 1 Taking the omnidirectional indoor distribution antenna shown as an example, Figure 6 The radiation pattern of the horizontal polarization element 2 is a first example of an omnidirectional indoor distributed antenna according to an embodiment of this disclosure; Figure 7 The standing wave diagram of the horizontal polarization element 2 of the first example of the omnidirectional indoor distributed antenna according to the embodiments of this disclosure; as shown Figure 6 and 7 As shown, this omnidirectional indoor antenna has superior performance.

[0060] Second example: Figure 8 This is a schematic diagram of a second example of an omnidirectional indoor distribution antenna according to an embodiment of this disclosure; as shown Figure 8 As shown, in this example, the first radiating patch 201 and the second radiating patch 202 in the radiating structure 21 are rectangular. The main body 1211 of the first reflective component 121 is also rectangular. Unlike the first example, the second reflective component 122 is a full-surface structure, and it is not a single piece of the main body 1211. When there are five main bodies 1211, the outer contour of the second reflective component 122 is pentagonal, with one side sharing a side with one side of a main body 1211. The remaining structures in the second example are the same as those in the first example, and therefore will not be repeated here.

[0061] Third example: Figure 9 This is a schematic diagram of a third example of an omnidirectional indoor distribution antenna according to an embodiment of this disclosure; as shown Figure 9As shown, in this example, based on the structure of the first or second example, an auxiliary component 13 can be connected to the side of the first reflective component 121 away from the second reflective component 122. The tangent at any point on the auxiliary component 13 intersects the extension surface of the plane containing the main body 1211, and / or, the tangent at any point on the auxiliary component 13 intersects the extension surface of the plane containing the filling portion 1212. For example, the auxiliary component 13 can be arranged perpendicularly to the plane containing the second radiating component. Furthermore, the auxiliary component 13 can be a cylindrical structure. It can be seen that by adding the auxiliary component 13, the length of the first reflective component 121 is extended, and the area of ​​the reflective component is increased, based on the first and second examples. However, it should be noted that due to the increased area of ​​the reflective component, the dimensions of the first radiating patch 201 and the second radiating patch 202, their height relative to the main body 1211, and the position of the feed point all need to be adjusted accordingly to meet the antenna performance requirements.

[0062] Fourth example: Figure 10 This is a schematic diagram of the fourth example of an omnidirectional indoor distribution antenna according to embodiments of this disclosure; as shown Figure 10 As shown, in this example, the first reflective component 121 is a conical structure. That is, the filling portion 1212 between the multiple main body portions 1211 of the first reflective component 121 needs to be able to be spliced ​​with the main body portions 1211 to form a conical structure. In this case, the first reflective component 121 has no edges, and the edges of the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 are essentially without gaps to the edges of the first reflective component 121. This allows the edge currents of the first radiating patch 201 and the second radiating patch 202 to be as symmetrical as possible, improving the overall radiation pattern of the horizontal polarization unit 2. It should be noted that the shape and size of the oscillators of the first radiating patch 201 and the second radiating patch 202, their height relative to the reflective structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can all be changed to match the performance requirements of this structure.

[0063] Fifth example: Figure 11 This is a schematic diagram of the fifth example of an omnidirectional indoor distribution antenna according to embodiments of this disclosure; as shown Figure 11As shown, in this example, the first reflective component 121 is a planar structure. That is, the filling portion 1212 between the multiple main body portions 1211 of the first reflective component 121 needs to be able to be spliced ​​with the main body portions 1211 to form a planar structure. In this case, the phenomenon that the horizontal polarization unit 2 uses the reflective structure 12 as a reference electrode, which is caused by various asymmetric structures, results in a large gain difference in the azimuth angle within a 360° range at a certain pitch angle. However, since the main radiation direction angle of the horizontal polarization unit 2 will become smaller, under this structure, the shape and size of the oscillator of the first radiating patch 201 and the second radiating patch 202, the height between them and the reflective structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can all be changed to match the performance requirements under this structure.

[0064] Sixth example: Figure 12 This is a schematic diagram of the sixth example of an omnidirectional indoor distribution antenna according to embodiments of this disclosure; as shown Figure 12 As shown, in this example, the reflective structure 12 includes a first reflective structure 12 and a second reflective component 122. The second reflective component 122 is connected to the first reflective component 121 and is positioned opposite to the single-arm vibrator 11. The first reflective structure 12 includes only a plurality of sequentially connected main body portions 1211. The plane of each main body portion 1211 forms a third dihedral angle with the plane of the first reflective component 121, and the magnitudes of the third dihedral angles are equal. For example, the third dihedral angles formed by the plane of each main body portion 1211 and the plane of the first reflective component 121 are all 90°. That is, each main body portion 1211 is perpendicular to the base plate of the radome. In this example, the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 are rectangular, and the main body portion 1211 is also rectangular. In this case, the boundary conditions in each radiating structure 21 of the horizontal polarization unit 2 are consistent, and the spatial isolation between adjacent units is increased, reducing their respective coupling effects. Under this structure, the shape and size of the oscillators of the first radiating patch 201 and the second radiating patch 202, their height relative to the reflective structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can all be changed to match the performance requirements under this structure.

[0065] In some examples, the horizontal polarization unit 22 of this disclosure embodiment can be used as one of the MIMO (Multiple-Input Multiple-Output) antennas in the 5G band, and the vertical polarization antenna can be used as the basic coverage antenna for 2G / 3G / 4G / 5G ultra-wideband, wherein the 5G sub-band and the horizontal polarization unit 22 together form the MIMO antenna.

[0066] In some examples, an omnidirectional indoor distributed antenna can be a transceiver antenna, meaning it can both transmit and receive electromagnetic wave signals. Of course, an omnidirectional indoor distributed antenna is not limited to the structure described above; it can also include a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filtering unit. The antenna in the communication equipment can function as either a transmitting or receiving antenna. The transceiver unit can include a baseband and a receiver. The baseband provides signals in at least one frequency band, such as 2G, 3G, 4G, and 5G signals, and transmits these signals to the radio frequency transceiver. After receiving the signal, the antenna in the communication system can process it through a filtering unit, a power amplifier, a signal amplifier, and the radio frequency transceiver before transmitting it to the receiver in the transceiver unit. The receiver could be, for example, a smart gateway.

[0067] Furthermore, the RF transceiver is connected to the transceiver unit and is used to modulate the signals transmitted by the transceiver unit, or to demodulate the signals received by the antenna before transmitting them 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 these signals before sending them to the antenna. The antenna receives the signals and transmits them to the receiving circuit of the RF transceiver. The receiving circuit then transmits the signals to the demodulation circuit, which demodulates the signals before transmitting them to the receiving end.

[0068] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, which are then connected to a filtering unit. The filtering unit is connected to at least one antenna. During signal transmission in the communication system, the signal amplifier improves the signal-to-noise ratio (SNR) of the RF transceiver's output signal before transmitting it to the filtering unit; the power amplifier amplifies the power of the RF transceiver's output signal before transmitting it to the filtering unit. The filtering unit may specifically include a duplexer and a filtering circuit. The filtering unit combines the signals output from the signal amplifier and power amplifier, filters out clutter, and transmits them to the antenna, which then radiates the signal. During signal reception in the communication system, the antenna receives the signal and transmits it to the filtering unit. The filtering unit filters out clutter from the received signal and transmits it to the signal amplifier and power amplifier. The signal amplifier increases the gain of the received signal, improving the SNR; the power amplifier amplifies the power of the received signal. The signal received by the antenna, after processing by the power amplifier and signal amplifier, is transmitted to the RF transceiver, which then transmits it to the transceiver unit.

[0069] In some examples, the signal amplifier may include various types of signal amplifiers, such as low-noise amplifiers, without limitation.

[0070] In some examples, the omnidirectional indoor distributed antenna provided in this disclosure embodiment further includes a power management unit connected to a power amplifier and providing the power amplifier with a voltage for amplifying the signal.

[0071] Secondly, embodiments of this disclosure provide an electronic device that includes any of the omnidirectional indoor distributed antennas described above. Because the electronic device in these embodiments includes the aforementioned omnidirectional indoor distributed antenna, its signal is better.

[0072] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
