[0039] In a first aspect, FIG. 1 is a perspective view of an omni-directional room-division antenna according to an embodiment of the present disclosure; FIG. 2 is a top view of the omni-directional room-division antenna according to an embodiment of the present disclosure; and FIG. 3 is a partial sectional view of the omni-directional room-division antenna according to an embodiment of the present disclosure. As shown in FIGS. 1-3, the omni-directional room-division antenna according to an embodiment of the present disclosure is a dual-polarized antenna, which can include a vertical polarization unit 1 and a horizontal polarization unit 2. The vertical polarization unit 1 includes a monopole 11 and a reflection structure 12, and the monopole 11 and the reflection structure 12 are oppositely arranged. The reflection structure 12 has oppositely arranged first and second surfaces, and the first surface is closer to the monopole 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 21, which are arranged on the side of the first surface of the reflection structure 12 away from the second surface and are spaced apart along the circumference of the first surface. In particular, in the embodiment of the present disclosure, the reflection structure 12 includes at least a first reflection component 121, which includes a plurality of body portions 1211 arranged in sequence along the circumference thereof, and one radiation structure 21 is arranged on one body portion 1211, for example, the body portion 1211 and the radiation structure 21 are arranged one-to-one. The radiation structure 21 includes at least one radiation patch, and the outer contour of the body portion 1211 is adapted to the outer contour of the radiation patch. For example, the contour of the radiation patch is rectangular, and the contour of the body portion 1211 is also rectangular, and the side edges thereof are arranged one-to-one.

[0040] Referring to FIG. 1, the single-arm resonator 11 in the vertical polarization unit 1 is taken as an example of a cone-cylinder structure, and the vertical polarization unit 1 can be used as a broadband omnidirectional antenna by feeding the single-arm resonator 11 and cooperating with the reflection of the reflection structure 12. The radiation structure 21 in the horizontal polarization unit 2 can be a single-layer radiation patch or a double-layer radiation patch, that is, the horizontal polarization unit 2 can be used as a patch antenna, which has the characteristics of high gain and wide beam. In the embodiments of the present disclosure, only the double-layer radiation patch is taken as an example, and for the convenience of description, the one close to the main body 1211 is referred to as the first radiation patch 201, and the other is referred to as the second radiation patch 202. In the embodiments of the present disclosure, since the radiation structure 21 is arranged on the main body 1211, the main body 1211 is equivalent to the reference electrode of the radiation structure 21 at this time, and at the same time, the outer contour of the main body 1211 and the first radiation patch 201 / second radiation patch 202 located thereon are matched, that is, the distance between the edge of the main body 1211 and the edge of the first radiation patch 201 / second radiation patch 202 can be relatively shortened, so that the high-tilt-angle (for example, Theta≥60°) gain of the horizontal polarization unit 2 can be improved, the edge current of the first radiation patch 201 and the second radiation patch 202 can be as symmetrical as possible, and the overall directional diagram of the horizontal polarization unit 2 can be improved. In the embodiments of the present disclosure, the first radiation patch 201 and the second radiation patch 202 are taken as an example, wherein the distance between the first radiation patch 201 and the second radiation patch 202 in each radiation structure 21 can be maintained by a fixing member. The first radiation patch 201 can be fixed on the main body 1211 by a supporting member, and at this time, the main body 1211 serves as the reference electrode of the radiation structure 21, and the medium between the main body 1211 and the first radiation patch 201 is air. In this case, the double-layer radiation patch is used as a radiator, which can improve the gain and bandwidth. The supporting member can be a nylon column, a plastic buckle or the like, which will not be listed one by one here. The fixing member and the supporting member can be made of the same material.

[0041] Of course, the first radiation patch 201 in the radiation structure 21 can also be arranged on a dielectric substrate and fixed on the main body 1211 by the dielectric substrate, wherein the dielectric substrate can be a PCB.

[0042] In one example, the second radiation patch 202 is located within the orthographic projection of the first radiation patch 201 on the plane where the main body 1211 is located, in which case the size of the first radiation patch 201 is greater than the size of the second radiation patch 202. In another example, the second radiation patch 202 covers the orthographic projection of the first radiation patch 201 on the plane where the main body 1211 is located, in which case the size of the first radiation patch 201 is smaller than the size of the second radiation patch 202. In the various drawings of the embodiments of the present disclosure, only the size of the first radiation patch 201 of each radiation structure 21 is greater than the size of the second radiation patch 202 is taken as an example.

[0043] In some examples, the shapes of the first radiation patch 201 and the second radiation patch 202 can be the same or different. In the embodiments of the present disclosure, the shapes of the first radiation patch 201 and the second radiation patch 202 can be selected from a circle, an ellipse, a polygon, or a special shape, etc. When the shapes of the first radiation patch 201 and the second radiation patch 202 are polygons, the shapes of both can be a rectangle, a square, a hexagon, a trapezoid, etc. In the embodiments of the present disclosure, only the first radiation patch 201 and the second radiation patch 202 are taken as an example of a rectangle, and it should be understood that the shape of the main body 1211 is also a rectangle at this time.

[0044] In some examples, the horizontally polarized unit 2 in the embodiments of the present disclosure not only includes the radiation structure 21 described above, but also includes a plurality of feeding assemblies 22 and a power division network 23. Among them, the power division network 23 has a first feeding port and a plurality of second feeding ports, and one second feeding port is electrically connected to one radiation structure 21 through one feeding assembly 22. In this case, the electromagnetic wave signal fed into the first feeding port of the power division network 23 is then fed into the feeding assembly 22 through the second feeding port, and the feeding assembly 22 then feeds the electromagnetic wave signal into the radiation structure 21 for radiation.

[0045] Specifically, the power division network 23 is a one-to-many power divider, for example, the number of radiation structures 21 is 5, and the power division network is a one-to-five power divider, and the number of corresponding feeding assemblies 22 is also 5. Among them, the one-to-five power divider has one main path and five branch paths, and the main path and the branch path both have a first end and a second end. The first end of the main path is used as the first feeding port of the power division network 23, the second end of the main path is connected to the first end of each branch path, and the second end of the branch path is used as the second feeding port.

[0046] Among them, the material of the dielectric plate of the one-to-many power divider can be a PCB dielectric plate such as polytetrafluoroethylene, glass, fiber pressboard, etc.

[0047] In some examples, FIG. 4 is a schematic view of a first coaxial cable of an omni-directional chamber antenna according to an embodiment of the present disclosure; as shown in FIG. 4, the feeding 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 which are nested in sequence. The first coaxial cable includes a first connecting end and a second connecting end, and a first transmission section connected between the first connecting end and the second connecting end. The first core 221 of the first connecting end is electrically connected with the radiating structure 21, and the core of the second connecting end is connected with a second feeding port. For the first connecting end, in the direction from the first connecting end to the second connecting 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 with the reflecting structure 1212, and the part of the first connecting end exposing the first dielectric layer 222 extends from the second surface side of the reflecting structure 12 to the first surface side through the first via hole penetrating the reflecting structure 1212, and the exposed core of the first connecting end is electrically connected with the radiating structure 21, and the connection position is the feeding point of the radiating structure 21. Further, the reflecting structure 12 can be a ground electrode, and the first reference electrode layer 223 is connected with the reflecting structure 12, and at this time the signal loaded on the first reference electrode layer 223 is a ground signal. The connection between the first reference electrode layer 223 and the reflecting structure 12 can be by welding or by screwing. Of course, without affecting the performance of the antenna, any way of electrically connecting the first reference electrode layer 223 and the reflecting structure 12 can be adopted.

[0048] When the feeding assembly 22 adopts the first coaxial cable, the first core 221 of the first coaxial cable is connected with the first radiating patch 201201, and the connection position is the feeding point. The operating frequency of the horizontal polarization unit 22 can be adjusted according to the need by adjusting the distance between the first radiating patch 201201 and the second radiating patch 202202 in the radiating structure 2121, the shapes and sizes of the two, and the position of the feeding point, so as to realize a horizontal polarization unit 2 with high gain and wide beam.

[0049] In some examples, the power division network 23 is arranged on the second surface side of the reflecting structure 12 away from the first surface, and at this time since the reflecting structure 12 is a conductive structure, an interlayer insulating layer is arranged between the second surface of the reflecting structure 12 and the power division network 23 to isolate the reflecting structure 12 from the power division network 23. In the embodiment of the present disclosure, the power division network 23 is arranged on the second surface side of the reflecting structure 12 and is isolated from the reflecting structure 12 by the interlayer insulating layer, which can save space on one hand, and can use the reflecting structure 12 as the reference ground of the power division network 23 to make the overall structure of the antenna simple.

[0050] In some examples, the vertical polarization unit 1 of the embodiments of the present disclosure not only includes the single-arm resonator 11 and the reflection structure 12 described above, but also includes a second coaxial cable for feeding the single-arm resonator 11. The second coaxial cable structure is the same as the first coaxial cable structure, that is, the second coaxial cable includes a second core, a second dielectric layer, a second reference electrode layer and a second protective layer which are nested in sequence; the second reference electrode layer is electrically connected with the reflection structure 12, and the second core is connected with the single-arm resonator 11 through the second via hole penetrating the reflection structure 12. In this case, the second reference electrode layer is connected with the reflection structure 12, that is, the signal of the second reference electrode layer is a ground signal, so that a separate signal terminal does not need to be provided for the second reference electrode layer. Moreover, most of the structure of the second coaxial cable is arranged in the cone structure of the reflection structure 12, so that the space can be saved.

[0051] In some examples, continuing to refer to FIG. 1, the omni-directional chamber antenna in the embodiments of the present disclosure not only includes the structure described above, but also includes a radome, and the vertical polarization unit 1 and the horizontal polarization unit 2 are located in the radome. Specifically, the radome can include a first part and a second part, the reflection structure 12 of the vertical polarization unit 1 and the horizontal polarization unit 2 are located in the first part, and the single-arm resonator 11 of the vertical polarization unit 1 is located in the second part. Among them, the reflection structure 12 is fixed on the bottom plate of the first part of the radome, for example, the reflection structure 12 and the bottom surface of the first part of the radome are fixed by bolts. A limiting piece is arranged at the top of the second part of the radome, which is used to prevent the single-arm resonator 11 from shaking and affecting the performance of the antenna. In one example, the radome can be made of plastic resin material.

[0052] In some examples, no matter which structure the horizontal polarization unit 2 in the embodiments of the present disclosure adopts, the number of the radiation structures 21 in the horizontal polarization unit 2 can be various, for example, three, four, five, six, etc. In the above examples, the number of the radiation structures 21 is taken as five as an example. In the embodiments of the present disclosure, by reasonably setting the number of the radiation structures 21, the gain can be effectively improved, and the directivity pattern roundness can be better.

[0053] In order to make the specific structure of the reflection structure 12 in the omni-directional chamber antenna of the embodiments of the present disclosure clearer, and the corresponding relationship between the reflection structure 12 and the radiation structure 21 clearer, the following will be described in combination with specific examples.

[0054] The first example: with reference to FIGS. 1 and 2, in this example, the reflecting structure 12 includes a first reflecting component 121 and a second reflecting component 122. The first reflecting component 121 includes a plurality of body parts 1211 and filling parts 1212 connected between the body parts 1211. The second reflecting component 122 is connected with the body parts 1211 and is arranged opposite to the single-arm oscillator 11. The body parts 1211 are rectangular, and the filling parts 1212 are triangular. The extension plane of the plane where the body parts 1211 are located and the extension plane of the plane where the second reflecting component 122 are located form a first dihedral angle, the extension plane of the plane where the filling parts 1212 are located and the extension plane of the plane where the second reflecting component 122 are located form a second dihedral angle, and the first dihedral angle is not equal to the second dihedral angle. That is, the plane where the body parts 1211 are located and the plane where the filling parts 1212 are located are not in the same plane. The body parts 1211 and the first radiation patch 201 / second radiation patch 202 of the radiation structure 21 located thereon are rectangular, at this time, the size of the first radiation patch 201 / second radiation patch 202 can be adjusted to reduce the distance between the first radiation patch 201 / second radiation patch 202 and the edge of the body part 1211, and correspondingly arranged, so that the edge current of the first radiation patch 201 and the second radiation patch 202 is as symmetrical as possible, and the overall pattern of the horizontally polarized unit 2 can be improved.

[0055] In some examples, the extension plane of the plane where each body part 1211 is located and the plane where the second reflecting component 122 are located form a first dihedral angle, and the extension plane of the plane where each filling part 1212 is located and the plane where the second reflecting component 122 are located form a second dihedral angle. In this case, the structure design of the first reflecting component 121 is facilitated. Further, the size of each body part 1211 can be designed to be the same, and the size of each filling part 1212 can be designed to be the same.

[0056] In some examples, the body parts 1211 and the first radiation patch 201 and the second radiation patch 202 located thereon are arranged in parallel. In this way, it is convenient to feed the first radiation patch 201.

[0057] In some examples, FIG. 5 is a schematic view of the first reflecting component 121 of the first example of the omnidirectional indoor antenna according to the embodiment of the present disclosure; as shown in FIG. 5, the first reflecting component 121 further includes a plurality of connection parts 1213 connected in sequence, one connection part 1213 connects one body part 1211, and the connection parts 1213 and the body parts 1211 connected with each other are an integral structure; each connection part 1213 is connected with the second reflecting component 122.

[0058] In some examples, continuing to refer to FIG. 2, the reflecting structure 12 not only includes the first reflecting component 121 and the second reflecting component 122, but also includes a fixing component 123. The fixing component 123 is connected on the side of the first reflecting component 121 away from the second reflecting component 122, and is configured to be fixed with the bottom plate of the radome to realize the fixing of the reflecting structure 12 and the radome.

[0059] Specifically, the fixing component 123 can include a first fixing part 123a and a second fixing part 123b, the first fixing part 123a is connected with the main body part 1211, and the second fixing part 123b is connected with the filling part 1212, the first fixing part 123a and the second fixing part 123b are both arc-shaped, and the connecting line of the arc of each first fixing part 123a and the arc of each second fixing part 123b forms a circle. The first fixing part 123a and the second fixing part 123b are both arranged on the bottom plate of the radome, and are fixedly connected with the bottom plate of the radome, for example, fixedly connected by means of screws, buckles or the like. That is, the outer contour of the orthographic projection of the reflecting structure 12 composed of the first reflecting component 121, the second reflecting component 122 and the fixing component 123 on the plane of the bottom plate of the radome is circular.

[0060] Taking the omni-directional indoor antenna shown in FIG. 1 as an example, FIG. 6 is a radiation pattern of the horizontal polarization unit 2 of the first example of the omni-directional indoor antenna according to the embodiment of the present disclosure; and FIG. 7 is a standing wave pattern of the horizontal polarization unit 2 of the first example of the omni-directional indoor antenna according to the embodiment of the present disclosure. As shown in FIGS. 6 and 7, the performance of the omni-directional indoor antenna is relatively optimal.

[0061] Second example: FIG. 8 is a structural schematic diagram of the second example of the omni-directional indoor antenna according to the embodiment of the present disclosure. As shown in FIG. 8, the first radiation patch 201 and the second radiation patch 202 in the radiation structure 21 in this example adopt a rectangular shape, and the main body part 1211 of the first reflecting component 121 also adopts a rectangular shape. The second reflecting component 122 in this example is a whole surface structure, and is not an integral structure with the main body part 1211. When the main body part 1211 is five, the outer contour of the second reflecting component 122 is a pentagon, and one side of the pentagon is co-located with one side of the main body part 1211. The remaining structures in the second example adopt the same structures as in the first example, and thus are not repeated here.

[0062] Third example: Fig. 9 is a structural schematic diagram of a third example of the omni-directional indoor antenna according to the present disclosure; as shown in Fig. 9, in this example, an auxiliary component 13 can be connected to the first reflecting component 121 on the side away from the second reflecting component 122 based on the structure of the first example or the second example. The tangent of any point on the auxiliary component 13 intersects the extension plane of the plane where the main body 1211 is located, and / or the tangent of any point on the auxiliary component 13 intersects the extension plane of the plane where the filling part 1212 is located. For example, the auxiliary component 13 can be arranged vertically with respect to the plane where the second radiating component is located. Further, 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 reflecting component 121 is extended based on the first example and the second example, and the area of the reflecting component is increased. However, it should be noted that, due to the increase in the area of the reflecting component, the size of the first radiating patch 201 and the second radiating patch 202, the height with respect to the main body 1211, and the position of the feed point all need to be adjusted to meet the performance of the antenna.

[0063] Fourth example: Fig. 10 is a structural schematic diagram of a fourth example of the omni-directional indoor antenna according to the present disclosure; as shown in Fig. 10, in this example, the first reflecting component 121 is a conical structure, that is, the filling part 1212 between the main body 1211 of the first reflecting component 121 needs to be able to splice to form a conical structure. In this case, the first reflecting component 121 does not have edges, and the edges of the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 are equivalent to having no spacing with the edges of the first reflecting component 121, which can make the edge current of the first radiating patch 201 and the second radiating patch 202 as symmetrical as possible, and can improve the overall directional diagram of the horizontal polarization unit 2. It should be noted that the shape and size of the resonator of the first radiating patch 201 and the second radiating patch 202, the height between the reflecting structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can be changed to match the performance requirements under this structure.

[0064] Fifth example: Fig. 11 is a structural schematic diagram of a fifth example of an omni-directional room-split antenna according to an embodiment of the present disclosure; as shown in Fig. 11, in this example, the first reflecting component 121 is a planar structure, that is, the filling part 1212 between the plurality of main parts 1211 of the first reflecting component 121 needs to be able to be spliced to form a planar structure. In this case, the horizontal polarization unit 2 adopts the reflecting structure 12 as the reference electrode, and the phenomenon that the gain difference of the directional diagram in the 360° range is large at a certain elevation angle due to various asymmetric structures is eliminated. However, the main radiation direction angle of the horizontal polarization unit 2 will be smaller, and in this structure, the shape and size of the oscillators of the first radiating patch 201 and the second radiating patch 202, the height between the oscillators and the reflecting structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can be changed to match the performance requirements under this structure.

[0065] Sixth example: Fig. 12 is a structural schematic diagram of a sixth example of an omni-directional room-split antenna according to an embodiment of the present disclosure; as shown in Fig. 12, in this example, the reflecting structure 12 includes a first reflecting structure 12 and a second reflecting component 122, the second reflecting component 122 is connected with the first reflecting component 121 and is arranged opposite to the single-arm oscillator 11; the first reflecting structure 12 only includes a plurality of sequentially connected main parts 1211; and the planes on which the main parts 1211 are located form third dihedral angles with the plane on which the first reflecting component 121 is located, and the third dihedral angles are equal in size. For example, the third dihedral angles formed by the planes on which the main parts 1211 are located and the plane on which the first reflecting component 121 is located are all 90°. That is, each main part 1211 is perpendicular to the bottom plate of the radome. In the example, the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 are rectangular, and the main parts 1211 are 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 of adjacent two units is increased, reducing the coupling effect of each other. In this structure, the shape and size of the oscillators of the first radiating patch 201 and the second radiating patch 202, the height between the oscillators and the reflecting structure 12, the spacing between the first radiating patch 201 and the second radiating patch 202, and the position of the feed point can be changed to match the performance requirements under this structure.

[0066] In some examples, the horizontal polarization unit 22 of the embodiment of the present disclosure can be used as one of the MIMO (Multiple Input Multiple Output) antennas of the 5G frequency band, and the vertical polarization antenna can be used as a basic coverage antenna of the 2G / 3G / 4G / 5G ultra-wide frequency band, wherein the 5G sub-band and the horizontal polarization unit 22 together constitute a MIMO antenna.

[0067] In some examples, the omni-directional sub-antenna can be a transceiving antenna, i.e., capable of both transmitting and receiving electromagnetic wave signals. Of course, the omni-directional sub-antenna is not limited to including the above structure, but also includes a transceiving unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filter unit. The antenna in the communication device can serve as a transmitting antenna or a receiving antenna. The transceiving unit can include a baseband and a receiving end. The baseband provides at least one frequency band of signals, such as 2G signals, 3G signals, 4G signals, 5G signals, etc., and transmits the at least one frequency band of signals to the radio frequency transceiver. After the antenna in the communication system receives the signals, the signals can be transmitted to the receiving end in the transceiving unit after being processed by the filter unit, the power amplifier, the signal amplifier, and the radio frequency transceiver. The receiving end can be a smart gateway, etc.

[0068] Further, the radio frequency transceiver is connected to the transceiving unit, and is used to modulate the signals transmitted by the transceiving unit or to demodulate the signals received by the antenna and transmitted to the transceiving unit. Specifically, the radio frequency transceiver can include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives the various types of signals provided by the baseband, the modulation circuit can modulate the various types of signals provided by the baseband and then transmit the signals to the antenna. After the antenna receives the signals and transmits them to the receiving circuit of the radio frequency transceiver, the receiving circuit transmits the signals to the demodulation circuit, and the demodulation circuit demodulates the signals and then transmits them to the receiving end.

[0069] Further, the radio frequency transceiver is connected to the signal amplifier and the power amplifier, and the signal amplifier and the power amplifier are connected to the filter unit, and the filter unit is connected to at least one antenna. In the process of transmitting signals in the communication system, the signal amplifier is used to improve the signal-to-noise ratio of the signals output by the radio frequency transceiver and then transmits the signals to the filter unit; the power amplifier is used to amplify the power of the signals output by the radio frequency transceiver and then transmits the signals to the filter unit; the filter unit can specifically include a duplexer and a filter circuit, and the filter unit combines and filters the signals output by the signal amplifier and the power amplifier and then transmits the signals to the antenna, and the antenna radiates the signals. In the process of receiving signals in the communication system, the antenna receives the signals and transmits them to the filter unit, the filter unit filters the signals received by the antenna and then transmits the signals to the signal amplifier and the power amplifier, the signal amplifier increases the gain of the signals received by the antenna to increase the signal-to-noise ratio of the signals, and the power amplifier amplifies the power of the signals received by the antenna. After the signals received by the antenna are processed by the power amplifier and the signal amplifier, the signals are transmitted to the radio frequency transceiver, and then transmitted to the transceiving unit.

[0070] In some examples, the signal amplifier can include various types of signal amplifiers, such as low-noise amplifiers, without limitation.

[0071] In some examples, the omni-directional chamber-divided antenna further comprises a power management unit connected to the power amplifier, and the power management unit provides a voltage for the power amplifier to amplify the signal.

[0072] In a second aspect, the present disclosure provides an electronic device comprising the omni-directional chamber-divided antenna described above. Since the electronic device comprises the omni-directional chamber-divided antenna described above, the signal is better.
