[0040] 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 with reference to the accompanying drawings and specific implementation methods.

[0041] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0042] In the first aspect, FIG1 is a stereoscopic view of an omnidirectional room antenna according to an embodiment of the present disclosure; FIG2 is a top view of an omnidirectional room antenna according to an embodiment of the present disclosure; as shown in FIG1 and FIG2, an embodiment of the present disclosure provides an omnidirectional room antenna, which is a dual-polarization antenna, and 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 reflection structure 12, and the single-arm oscillator 11 and the reflection structure 12 are arranged opposite to each other. The reflection 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 21, and the plurality of radiation structures 21 are located on the side of the first surface of the reflection structure 12 away from the second surface, and are arranged at intervals along the circumference of the first surface.

[0043] 1 , the single-arm oscillator 11 in the vertical polarization unit 1 adopts a conical column structure, and the reflective structure 12 adopts a disk-cone structure. By feeding the single-arm oscillator 11 and coordinating the reflection of the reflective structure 12, the vertical polarization unit 1 can be used as a broadband omnidirectional antenna. The radiation structure 21 in the horizontal polarization unit 2 can adopt 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 this case, the omnidirectional indoor antenna provided by the embodiment of the present disclosure is a high-gain, wide-beam omnidirectional antenna.

[0044] It should be noted that the reflective structure 12 in the vertical polarization unit 1 in the embodiment of the present disclosure may include a main body and a connecting portion. The main body is annular and has a first opening and a second opening. The size of the first opening is smaller than the size of the second opening, and the first opening is closer to the single-arm vibrator 11 than the second opening. The connecting portion is arranged at the first opening and connected to the first opening. The main body has a first surface and a second surface arranged in relative relation. The first surface of the main body serves as the first surface of the reflective structure 12, and the second surface of the main body serves as the second surface of the reflective structure 12.

[0045] In some examples, FIG3 is a partial cross-sectional view of an omnidirectional indoor antenna according to an embodiment of the present disclosure; as shown in FIG3 , the horizontal polarization unit 2 according to an embodiment of the present disclosure includes not only the aforementioned multiple radiating structures 21, but also multiple feeding components 22 and a power splitting network 23. The power splitting network 23 has a first feeding port and multiple second feeding ports, and a second feeding port is electrically connected to a radiating structure 21 through a feeding component 22. In this case, the electromagnetic wave signal fed into the first feeding port of the power splitting network 23 is fed into the feeding component 22 through the second feeding port, and the feeding component 22 feeds the electromagnetic wave signal into the radiating structure 21 for radiation.

[0046] Specifically, the power splitting network 23 is a one-to-many power splitter. For example, if the number of radiating structures 21 is five, the power splitting network is a one-to-five power splitter, and the number of corresponding feeding components 22 is also five. The one-to-five power splitter has one main circuit and five branches. The main circuit and the branches each have a first end and a second end. The first end of the main circuit serves as the first feeding port of the power splitting network 23. The second end of the main circuit is connected to the first end of each branch. The second end of the branch serves as the second feeding port.

[0047] The material of the dielectric board of the one-to-many power splitter can be a PCB dielectric board such as polytetrafluoroethylene, glass, or fiber press board.

[0048] In some examples, Figure 4 is a schematic diagram of a first coaxial cable of an omnidirectional room antenna according to an embodiment of the present disclosure. As shown in Figure 4, the feed 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 connection end and a second connection end, and a first transmission segment connected between the first and second connection ends. 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 feed port. Regarding the first connection end, in a direction from the first connection end toward the second connection end, the first core 221, first dielectric layer 222, first reference electrode layer 223, and first protective layer 224 are exposed in sequence. The first reference electrode layer 223 is electrically connected to the reflective structure 12. The portion of the first connection end where the first dielectric layer 222 is exposed extends from the second surface side to the first surface side of the reflective structure 12 through a first via hole that penetrates the reflective structure 12. The exposed core of the first connection end is electrically connected to the radiating structure 21, and the connection location serves as the feed point of the radiating structure 21. Furthermore, the reflective structure 12 may be a ground electrode, and the first reference electrode layer 223 is connected to the reflective structure 12. In this case, the signal applied to the first reference electrode layer 223 is a ground signal. The connection between the first reference electrode layer 223 and the reflective structure 12 may be by welding or screwing. Of course, the electrical connection between the first reference electrode layer 223 and the reflective structure 12 may be achieved by any method without affecting antenna performance.

[0049] In some examples, the power splitting network 23 is disposed on the side of the second surface of the reflective structure 12 facing away from the first surface, that is, the power splitting network 23 is disposed within the conical disk structure of the reflective structure 12. In this case, 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 splitting network 23 to isolate the reflective structure 12 from the power splitting network 23. In the disclosed embodiments, disposing the power splitting network 23 within the conical disk structure of the reflective structure 12 and isolating it from the reflective structure 12 via the interlayer insulating layer not only saves space, but also allows the reflective structure 12 to serve as a reference ground for the power splitting structure, simplifying the overall antenna structure.

[0050] In some embodiments, the radiation structure 21 in the embodiment of the present disclosure is a patch structure. The radiation structure 21 in the embodiment of the present disclosure and the fixing method of the radiation structure 21 and the reflective structure 12 are described below with reference to specific examples.

[0051] Example 1: Continuing with Figures 1 and 3, the radiating structure 21 in this example can consist of two layers of radiating patches arranged sequentially along a direction away from the first surface of the reflective structure 12. For ease of description, the one of the two layers of radiating patches closest to the first surface of the reflective structure 12 is referred to as the first radiating patch 201, and the other is referred to as the second radiating patch 202. For each radiating structure 21, the orthographic projections of the first radiating patch 201 and the second radiating patch 202 on the plane containing the first surface of the reflective structure 12 at least partially overlap, and a certain distance exists between the first radiating patch 201 and the second radiating patch 202. This distance can be maintained by a fixing member 204. The first radiating structure 21 is fixed to the first surface of the reflective structure 12 via a support member 203. In this case, the reflective structure 12 can serve as a reference ground for the radiating structure 21, and air is the medium between the reflective structure 12 and the radiating patches. In this case, using a double layer of radiating patches as the radiator can improve gain and bandwidth.

[0052] In some examples, the support member 203 may be a nylon column, a plastic buckle, or other structures, which are not listed here. The spacing between the first radiating patch 201 and the second radiating patch 202 can be maintained by the fixing member 204 , which can be made of the same material as the support member 203 .

[0053] In one example, the orthographic projection of the second radiating patch 202 on the plane where the first surface of the reflective structure 12 is located is within the orthographic projection of the first radiating patch 201 on the plane where the first surface of the reflective structure 12 is located. 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 on the plane where the first surface of the reflective structure 12 is located covers the orthographic projection of the first radiating patch 201 on the plane where the first surface of the reflective structure 12 is located. In this case, the size of the first radiating patch 201 is smaller than the size of the second radiating patch 202. In the drawings of the embodiments of the present disclosure, only the example in which the size of the first radiating patch 201 of each radiating structure 21 is larger than the size of the second radiating patch 202 is used.

[0054] When the feed assembly 22 uses a first coaxial cable, the connection between the first core 221 of the first coaxial cable and the first radiating patch 201 is the feed point. The operating frequency of the horizontally polarized unit 2 can be adjusted as needed by adjusting the spacing between the first radiating patch 201 and the second radiating patch 202 in the radiating structure 21, as well as the shape and size of the first and second radiating patches, and the position of the feed point, thereby achieving a high-gain, wide-beam horizontally polarized unit 2.

[0055] In some examples, the shapes of the first radiating patch 201 and the second radiating patch 202 can be the same or different. In the embodiment of the present disclosure, the shapes of the first radiating patch 201 and the second radiating patch 202 can be selected from circular, elliptical, polygonal, or irregular shapes. When the shapes of the first radiating patch 201 and the second radiating patch 202 are polygonal, both shapes can be rectangular, square, hexagonal, trapezoidal, etc.

[0056] In one example, the first radiating patch 201 and the second radiating patch 202 in each radiating structure 21 have the same shape. For example, as shown in FIG1 , the first radiating patch 201 and the second radiating patch 202 are both rectangular; as shown in FIG5 , the first radiating patch 201 and the second radiating patch 202 are both elliptical; as shown in FIG6 , the first radiating patch 201 and the second radiating patch 202 are both circular; and as shown in FIG7 , the first radiating patch 201 and the second radiating patch 202 are both square.

[0057] In one example, as shown in Figure 8, the first radiating patch 201 and the second radiating patch 202 in each radiating structure 21 have different shapes. For example, the first radiating patch 201 is rectangular, and the second radiating patch 202 is elliptical. In this case, the different shapes of the radiating patches have different edge coupling strengths and positions, thereby changing the radiation pattern of the radiating structure 21 and, in turn, the pattern of the horizontal polarization unit 2, such as its circularity and isolation.

[0058] In one example, as shown in Figure 9, the first surface of the reflective structure 12 includes a first annular edge and a second annular edge arranged opposite to each other; the first radiation patch 201 includes a fifth edge and a sixth edge arranged opposite to each other, and the second radiation patch 202 includes a seventh edge and an eighth edge arranged opposite to each other; the fifth edge of each first radiation patch 201 is located on the third virtual annular edge parallel to the first annular edge, and the sixth edge of each first radiation patch 201 is located on the fourth virtual annular edge parallel to the second annular edge; the seventh edge of each second radiation patch 202 is located on the fifth virtual annular edge parallel to the first annular edge, and the eighth edge of each second radiation patch 202 is located on the sixth virtual annular edge parallel to the second annular edge. In this case, the first radiation patch 201 and the second radiation patch 202 are conformal to the reflective structure 12. For example, the first radiation patch 201 and the second radiation patch 202 are both roughly trapezoidal. At this time, the edges of the first radiation patch 201 and the second radiation patch 202 correspond to the edges of the reflective structure 12, so that the edge currents of the first radiation patch 201 and the second radiation patch 202 can be as symmetrical as possible, which can improve the overall radiation pattern of the horizontal polarization unit 2.

[0059] Furthermore, the first annular edge and the second annular edge are arranged in parallel, and correspondingly, the third virtual annular edge, the fourth virtual annular edge, the fifth virtual annular edge and the sixth virtual annular edge are all arranged in parallel with the first annular edge and the second annular edge.

[0060] In some examples, the first radiation patch 201 and the second radiation patch 202 may both be made of metal or alloy material, such as copper, aluminum alloy, etc.

[0061] Regardless of whether the horizontal polarization unit 2 in the embodiment of the present disclosure adopts any of the above structures, the number of radiation structures 21 in the horizontal polarization unit 2 can be multiple, such as three, four, five, six, etc. The above examples all take five radiation structures 21 as an example, and Figure 10 illustrates six radiation structures 21. In the embodiment of the present disclosure, by reasonably setting the number of radiation structures 21, the gain can be effectively improved, and the circularity of the radiation pattern can be made better. However, it should be understood that it is necessary to reasonably set the spacing between adjacent radiation structures 21 to reduce the coupling effect between the radiation structures 21 and ensure the actual efficiency of the radiation structure 21. In one example, the spacing between adjacent radiation structures 21 is equal.

[0062] In order to make the omnidirectional indoor antenna of the embodiment of the present disclosure clearer, FIG1 takes the horizontal polarization unit 2 including five radiating structures 21, and each radiating structure 21 includes a first radiating patch 201 and a second radiating patch 202, and the first radiating patch 201 and the second radiating patch 202 are both rectangular as an example for simulation. Among them, the five radiating structures 21 in the horizontal polarization unit 2 are fed by five first coaxial cables, and the five radiating structures 21 are respectively fixed on the first surface of the reflective structure 12 of the vertical polarization unit through support columns to form a circular array. The first core wire of the first coaxial cable is welded on the first radiating patch 201 to excite the five radiating structures 21 to work. The five coaxial feeding points are connected to a one-to-five power divider of equal amplitude and phase through the first coaxial cable to achieve simultaneous excitation of the five radiating structures 21 to form an omnidirectional radiating antenna. FIG11 is the directional diagram of the horizontal polarization unit 2 when the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 of the embodiment of the present disclosure are both rectangular. Figure 12 shows the standing wave performance of the horizontally polarized unit 2 when both the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 of the present disclosure are rectangular. The vertically polarized unit 1 is a broadband omnidirectional antenna consisting of a single-arm dipole 11 and a reflective structure 12. The dipole 11 and the reflective structure 12 are excited by a second coaxial cable, achieving omnidirectional radiation. Figure 13 shows the directional pattern of the horizontally polarized unit 2 when both the first radiating patch 201 and the second radiating patch 202 of the radiating structure 21 of the present disclosure are elliptical.

[0063] Second Example: Figure 14 is a cross-sectional view of a second example of the radiating structure 21 according to an embodiment of the present disclosure. As shown in Figure 14 , this example is substantially identical to the first example, differing only in that the first radiating patch 201 of the radiating structure 21 in this example is disposed on the first surface of the reflective structure 12 via a dielectric substrate 205. In other words, the radiating patch is formed on the dielectric substrate 205. The dielectric substrate 205 may be a PCB, or alternatively, a glass substrate, a plastic substrate, or the like. In this example, by disposing the PCB on the first surface of the reflective structure 12, for example, by tightly attaching the PCB to the first surface of the reflective structure 12, the two can be secured together via fasteners 204, including but not limited to plastic rivets. This improves the design freedom of the horizontal polarization unit 2.

[0064] The third example: FIG15 is a top view of the third example of the radiation structure 21 of the embodiment of the present disclosure; FIG16 is a cross-sectional view of the third example of the radiation structure 21 of the embodiment of the present disclosure; as shown in FIG15 and 16, in this example, the radiation structure 21 includes a single-layer radiation patch 200 structure. The radiation patch 200 is arranged on the first surface side of the reflective structure 12, and the radiation patch 200 can be fixed on the reflective structure 12 by a support 203. At this time, the reflective structure 12 can serve as a reference ground for the radiation structure 21, and the medium between the reflective structure 12 and the radiation patch 200 is air. In this case, a single-layer radiation patch 200 is used as the radiator, and the structure of the radiation structure 21 is simple, that is, the structure of the horizontal polarization unit 2 is simple.

[0065] It should be noted that when the feeding component 22 uses a first coaxial cable, the connection position between the first core 221 of the first coaxial cable and the radiation patch 200 is the feeding point. The S parameters of the horizontal polarization unit 2 can be adjusted by adjusting the size of the radiation patch 200, the distance between the radiation component and the reflective structure 12, and the position of the feeding point, and the operating frequency of the horizontal polarization unit 2 can be adjusted.

[0066] In some examples, the support member 203 may be a nylon column, a plastic buckle, or other structure, which are not listed here one by one.

[0067] In some examples, the shape of the radiating patch 200 can be any one of an elliptical, circular, or polygonal shape. When the radiating patch 200 is polygonal, the shape of the radiating patch 200 can be rectangular, square, hexagonal, trapezoidal, etc. As shown in Figure 15, the radiating patch 200 is rectangular. Figure 17 is another top view of the third example of the radiating structure 21 according to an embodiment of the present disclosure; as shown in Figure 17, the radiating patch 200 is square.

[0068] In one example, the reflective structure 12 has a first annular edge and a second annular edge disposed opposite each other, and the radiating patch 200 has a third edge and a fourth edge disposed opposite each other. The third edge of each radiating patch 200 is located on the first virtual annular edge, and the fourth edge of each radiating structure 21 is located on the second virtual annular edge; the first virtual annular edge is parallel to the first annular edge, and the second virtual annular edge is parallel to the second annular edge. In this case, each radiating patch 200 is conformal to the reflective structure 12. For example, the radiating patch 200 is roughly trapezoidal. In this case, the edges of the radiating patch 200 correspond to the edges of the reflective structure 12, making the edge currents of the radiating patch 200 as symmetrical as possible, thereby improving the overall radiation pattern of the antenna.

[0069] Furthermore, the first annular edge and the second annular edge are arranged in parallel, and correspondingly, the first virtual annular edge and the second virtual annular edge are arranged in parallel with the first annular edge and the second annular edge.

[0070] In some examples, the radiation patch 200 may be made of metal or alloy material, such as copper, aluminum alloy, etc.

[0071] Fourth Example: FIG18 is a top view of a fourth example of the radiating structure 21 according to an embodiment of the present disclosure. As shown in FIG18 , this example is substantially identical to the first example, differing only in that, in this example, the radiating patch 200 in the radiating structure 21 is disposed on the first surface of the reflective structure 12 via a dielectric substrate 205. In other words, the radiating patch 200 is formed on the dielectric substrate 205. The dielectric substrate 205 may be a PCB, or alternatively, a glass substrate, a plastic substrate, or the like. In this example, by disposing the PCB on the first surface of the reflective structure 12, for example, by tightly adhering to the first surface of the reflective structure 12, the design freedom of the horizontal polarization unit 2 can be increased.

[0072] The other structures of the fourth example can adopt the same structure as the third example, so they will not be repeated here.

[0073] In some examples, the vertical polarization unit 1 of the embodiment of the present disclosure includes not only the above-mentioned single-arm oscillator 11 and the reflective structure 12, but also a second coaxial cable for feeding the single-arm oscillator 11; 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 that passes through the reflective structure 12. In this case, the second reference electrode layer is connected to the transmitting structure, 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 arranged in the cone-disk structure of the reflective structure 12, so it can save space.

[0074] In some examples, the omnidirectional indoor antenna in the embodiments of the present disclosure includes not only the above-mentioned structure, but also includes an antenna cover, and the vertical polarization unit 1 and the horizontal polarization unit 2 are located inside the antenna cover. Specifically, the antenna cover may include a first part and a second part, the reflection 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 reflection structure 12 is fixed to the bottom surface of the first part of the antenna cover, for example, by bolts to fix the reflection structure 12 and the bottom surface of the first part of the antenna cover. A limiter is provided on the top of the second part of the antenna cover, and the limiter is used to prevent the single-arm vibrator 11 from shaking and affecting the antenna performance.

[0075] In one example, the radome may be made of a plastic resin material.

[0076] In some examples, the horizontal polarization unit 2 of the embodiment of the present disclosure can be used as one of the MIMO (multiple input multiple output) antennas for the 5G frequency band, and the vertical polarization antenna can be used as the basic coverage antenna for the 2G / 3G / 4G / 5G ultra-wide band, in which the 5G sub-band and the horizontal polarization unit 2 together constitute a MIMO antenna.

[0077] In some examples, the omnidirectional indoor antenna can be a transceiver antenna, that is, it can both transmit and receive electromagnetic wave signals. Of course, the omnidirectional indoor antenna is not limited to the above structure, but also includes a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filter 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. The baseband provides a signal of at least one frequency band, such as a 2G signal, a 3G signal, a 4G signal, a 5G signal, etc., and sends a signal of at least one frequency band to the radio frequency transceiver. After the antenna in the communication system receives the signal, it can be processed by the filter 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 can be, for example, a smart gateway.

[0078] Furthermore, a radio frequency transceiver is connected to the transceiver unit and is used to modulate the signals sent by the transceiver unit or to demodulate the signals received by the antenna and transmit them back to the transceiver unit. Specifically, the radio frequency 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 various types of signals provided by the baseband and then transmit them to the antenna. The antenna receives the signal and transmits it to the receiving circuit of the radio frequency transceiver. The receiving circuit transmits the signal to the demodulation circuit, which demodulates the signal and transmits it to the receiving end.

[0079] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, which are then connected to a filtering unit, which is connected to at least one antenna. When the communication system transmits signals, the signal amplifier is used to increase the signal-to-noise ratio of the signal output by the RF transceiver before transmitting it to the filtering unit. The power amplifier is used to amplify the power of the signal output by the RF transceiver 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 by the signal amplifier and the power amplifier, filters out noise, and then transmits them to the antenna, which radiates the signal. When the communication system receives signals, the antenna receives the signal and transmits it to the filtering unit. The filtering unit filters out noise from the signal received by the antenna and transmits it to the signal amplifier and power amplifier. 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 before being transmitted to the RF transceiver, which then transmits it to the transceiver unit.

[0080] In some examples, the signal amplifier may include various types of signal amplifiers, such as a low noise amplifier, which is not limited herein.

[0081] In some examples, the omnidirectional room antenna provided by the embodiments of the present disclosure further includes a power management unit, which is connected to a power amplifier to provide the power amplifier with a voltage for amplifying the signal.

Since the electronic device in the embodiment of the present disclosure comprises the above-mentioned omnidirectional room-divided antenna, its signal is better.

Those skilled in the art will appreciate that various modifications and improvements can be made without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
