[0041] First, Figure 1 A three-dimensional diagram of an omnidirectional indoor antenna according to an embodiment of the present disclosure; Figure 2 FIG. 1 is a top view of the omnidirectional indoor antenna according to an embodiment of the present disclosure; Figure 1 and 2As shown, an embodiment of the present disclosure provides an omnidirectional room antenna, which is a dual-polarized 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 that are 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.

[0042] Reference Figure 1 The single-arm oscillator 11 in the vertical polarization unit 1 adopts a conical column structure, and the reflection structure 12 adopts a disk-cone structure. By feeding the single-arm oscillator 11 and coordinating the reflection of the reflection 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 room antenna provided in the embodiment of the present disclosure is a high-gain, wide-beam omnidirectional antenna.

[0043] 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 part, the main body is an annular body, 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 part 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 is used as the first surface of the reflective structure 12, and the second surface of the main body is used as the second surface of the reflective structure 12.

[0044] In some examples, Figure 3 is a partial cross-sectional view of the omnidirectional room antenna according to an embodiment of the present disclosure; Figure 3 As shown, the horizontal polarization unit 2 of the embodiment of the present disclosure includes not only the above-mentioned multiple radiating structures 21, but also multiple feeding components 22 and a power division network 23. Among them, the power division 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 division 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.

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

[0047] In some examples, Figure 4 Schematic diagram of the first coaxial cable of the omnidirectional indoor antenna of the embodiment of the present disclosure; Figure 4 As shown, the feeding component 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 section connected between the first connection end and the second connection end. The core of the first connection end is electrically connected to the radiation structure 21, and the core of the second connection end is connected to a second feeding 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 reflective structure 12, the portion of the first dielectric layer 222 exposed at the first connection end passes through the first via hole penetrating the reflective structure 12, and extends from the second surface side of the reflective structure 12 to the first surface side, the exposed first core 221 of the first connection end is electrically connected to the radiation structure 21, and the connection position is the feeding point of the radiation structure 21. Further, the reflective structure 12 may be a ground electrode, and the first reference electrode layer 223 is connected to the reflective structure 12. At this time, 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 may be connected by welding or by screwing. Of course, the first reference electrode layer 223 and the reflective structure 12 may be electrically connected in any manner without affecting the antenna performance.

[0048] In some examples, the power division network 23 is arranged on the side of the second surface of the reflective structure 12 away from the first surface, that is, the power division network 23 is arranged in the cone-disk structure of the reflective structure 12. At this time, since the reflective structure 12 is a conductive structure, an interlayer insulating layer is arranged between the second surface of the reflective structure 12 and the power division network 23 to isolate the reflective structure 12 from the power division network 23. In the embodiment of the present disclosure, the power division network 23 is arranged in the cone-disk structure of the reflective structure 12 and is isolated from the reflective structure 12 by the interlayer insulating layer. On the one hand, space can be saved, and on the other hand, the reflective structure 12 can be used as a reference ground for the power division structure to simplify the overall structure of the antenna.

[0049] 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 reflection structure 12 are described below with reference to specific examples.

[0050] The first example: Continue to refer to Figure 1 and 3 In this example, the radiation structure 21 may be composed of two layers of radiation patches arranged in sequence along the direction away from the first surface of the reflective structure 12. For the convenience of description, one of the two layers of radiation patches close to the first surface of the reflective structure 12 is called the first radiation patch 201, and the other is called the second radiation patch 202. For each radiation structure 21, the orthographic projections of the first radiation patch 201 and the second radiation patch 202 on the plane where the first surface of the reflective structure 12 is located at least partially overlap, and there is a certain distance between the first radiation patch 201 and the second radiation patch 202. The distance between the first radiation patch 201 and the second radiation patch 202 can be maintained by a fixing member 204. The first radiation structure 21 is fixed to the first surface of the reflective structure 12 by a supporting member 203. At this time, the reflective structure 12 can be used as a reference ground for the radiation structure 21, and the medium between the reflective structure 12 and the radiation patch is air. In this case, using a double-layer radiation patch as a radiator can improve gain and bandwidth.

[0051] In some examples, the support member 203 may be a nylon column, a plastic buckle, etc., which are not listed here. The spacing between the first radiation patch 201 and the second radiation patch 202 may be maintained by the fixing member 204 , and the fixing member 204 may be made of the same material as the support member 203 .

[0052] In one example, the orthographic projection of the second radiation patch 202 on the plane where the first surface of the reflective structure 12 is located is located within the orthographic projection of the first radiation patch 201 on the plane where the first surface of the reflective structure 12 is located. In this case, the size of the first radiation patch 201 is larger than the size of the second radiation patch 202. In another example, the orthographic projection of the second radiation patch 202 on the plane where the first surface of the reflective structure 12 is located covers the orthographic projection of the first radiation patch 201 on the plane where the first surface of the reflective structure 12 is located. In this case, the size of the first radiation patch 201 is smaller than the size of the second radiation patch 202. In the drawings of the embodiments of the present disclosure, only the example that the size of the first radiation patch 201 of each radiation structure 21 is larger than the size of the second radiation patch 202 is taken.

[0053] When the feeding component 22 adopts the first coaxial cable, the first core 221 of the first coaxial cable is connected to the first radiation patch 201, and the connection position is the feeding point. The operating frequency of the horizontal polarization unit 2 can be adjusted according to the spacing between the first radiation patch 201 and the second radiation patch 202 in the radiation structure 21, the shape and size of the two, and the position of the feeding point, so as to realize a high-gain, wide-beam horizontal polarization unit 2.

[0054] In some examples, the shapes of the first radiation patch 201 and the second radiation patch 202 may be the same or different. In the embodiment of the present disclosure, the shapes of the first radiation patch 201 and the second radiation patch 202 may be selected from circular, elliptical, polygonal or irregular shapes. When the shapes of the first radiation patch 201 and the second radiation patch 202 are polygonal, the shapes of both may be rectangular, square, hexagonal, trapezoidal, etc.

[0055] In one example, the first radiation patch 201 and the second radiation patch 202 in each radiation structure 21 have the same shape. Figure 1 The first radiation patch 201 and the second radiation patch 202 are both rectangular; Figure 5 As shown, the first radiation patch 201 and the second radiation patch 202 are both elliptical; Figure 6 As shown, the first radiation patch 201 and the second radiation patch 202 are both circular; Figure 7 As shown, the first radiation patch 201 and the second radiation patch 202 are both square.

[0056] In one example, if Figure 8As shown, the first radiation patch 201 and the second radiation patch 202 in each radiation structure 21 have different shapes, for example, the first radiation patch 201 is rectangular, and the second radiation patch 202 is elliptical. In this case, the edge coupling strength and position of radiation patches of different shapes are different, so that the radiation pattern of the radiation structure 21 can be changed, and then the pattern of the horizontal polarization unit 2, such as the circularity of the pattern, isolation and other indicators can be changed.

[0057] In one example, if Fig. 9 As shown, the first surface of the reflective structure 12 includes a first annular edge and a second annular edge that are opposite to each other; the first radiation patch 201 includes a fifth edge and a sixth edge that are opposite to each other, and the second radiation patch 202 includes a seventh edge and an eighth edge that are 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 with 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, thereby improving the overall radiation pattern of the horizontal polarization unit 2.

[0058] Further, 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.

[0059] 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.

[0060] Regardless of the above structures of the horizontal polarization unit 2 in the embodiment of the present disclosure, the number of the radiation structures 21 in the horizontal polarization unit 2 can be multiple, such as three, four, five, six, etc. In the above examples, five radiation structures 21 are used as an example. Fig.10The figure shows that there are 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 the spacing between adjacent radiation structures 21 needs to be reasonably set 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.

[0061] In order to make the omnidirectional indoor antenna of the present disclosure more clear, Figure 1 The simulation is performed by taking the horizontal polarization unit 2 as an example, wherein the five radiation structures 21 are included, and each radiation structure 21 includes a first radiation patch 201 and a second radiation patch 202, and the first radiation patch 201 and the second radiation patch 202 are both rectangular. The five radiation structures 21 in the horizontal polarization unit 2 are fed by five first coaxial cables, and the five radiation structures 21 are respectively fixed on the first surface of the reflection structure 12 of the vertical polarization unit through support columns to form a circular ring array, and the first core wire of the first coaxial cable is welded on the first radiation patch 201 to excite the five radiation structures 21 to work, and the five coaxial feeding points are connected to a one-to-five power divider with equal amplitude and phase through the first coaxial cable, so as to realize simultaneous excitation of the five radiation structures 21 and form an omnidirectional radiation antenna. Fig.11 This is the directivity diagram of the horizontal polarization unit 2 when the first radiation patch 201 and the second radiation patch 202 of the radiation structure 21 of the embodiment of the present disclosure are both rectangular. Fig.12 The standing wave performance diagram of the horizontal polarization unit 2 when the first radiation patch 201 and the second radiation patch 202 of the radiation structure 21 of the embodiment of the present disclosure are both rectangular. The vertical polarization unit 1 is a broadband omnidirectional antenna, which is divided into a single-arm vibrator 11 and a reflection structure 12. The single-arm vibrator 11 and the reflection structure 12 are excited by a second coaxial cable to achieve omnidirectional radiation. Fig.13 This is the directivity diagram of the horizontal polarization unit 2 when the first radiation patch 201 and the second radiation patch 202 of the radiation structure 21 of the embodiment of the present disclosure are both elliptical.

[0062] Second example: Fig.14 is a cross-sectional view of a second example of the radiation structure 21 of the embodiment of the present disclosure; Fig.14As shown, this example is substantially the same as the first example structure, and the only difference is that the first radiation patch 201 of the radiation structure 21 in this example is arranged on the first surface of the reflective structure 12 through the dielectric substrate 205. That is, the radiation patch is formed on the dielectric substrate 205. The dielectric substrate 205 can be a PCB, and of course, the dielectric substrate 205 can also be a glass substrate, a plastic substrate, etc. In this example, by arranging the PCB on the first surface of the reflective structure 12, for example, the PCB is tightly attached to the first surface of the reflective structure 12, the two can be fixed together by a fixing member 204 including but not limited to a plastic rivet, etc., in this case, the design freedom of the horizontal polarization unit 2 can be improved.

[0063] The third example: Fig.15 is a top view of a third example of the radiation structure 21 according to the embodiment of the present disclosure; Fig.16 FIG. 2 is a cross-sectional view of a third example of the radiation structure 21 according to an embodiment of the present disclosure; Fig.15 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 be used 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 a radiator, and the structure of the radiation structure 21 is simple, that is, the structure of the horizontal polarization unit 2 is simple.

[0064] It should be noted that when the feeding component 22 adopts the 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.

[0065] 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.

[0066] In some examples, the shape of the radiation patch 200 may be any one of an ellipse, a circle, and a polygon. When the radiation patch 200 is a polygon, the shape of the radiation patch 200 may be a rectangle, a square, a hexagon, a trapezoid, etc. Fig.15 As shown, the radiating patch 200 is rectangular. Fig.17 FIG. 2 is another top view of the third example of the radiation structure 21 according to the embodiment of the present disclosure; Fig.17 As shown, the radiating patch 200 is square in shape.

[0067] In one example, the reflective structure 12 has a first annular edge and a second annular edge that are relatively set, and the radiation patch 200 has a third edge and a fourth edge that are relatively set. The third edge of each radiation patch 200 is located on the first virtual annular edge, and the fourth edge of each radiation 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 radiation patch 200 is conformal to the reflective structure 12, for example, the radiation patch 200 is roughly trapezoidal, and the edge of the radiation patch 200 corresponds to the edge of the reflective structure 12, so that the edge current of the radiation patch 200 can be as symmetrical as possible, which can improve the overall radiation pattern of the antenna.

[0068] 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.

[0069] In some examples, the radiation patch 200 may be made of metal or alloy material, such as copper, aluminum alloy, etc.

[0070] Fourth example: Fig.18 FIG. 2 is a top view of a fourth example of the radiation structure 21 according to an embodiment of the present disclosure; Fig.18 This example is substantially the same as the first example structure, except that, in this example, the radiation patch 200 in the radiation structure 21 is disposed on the first surface of the reflective structure 12 through the dielectric substrate 205. That is, the radiation patch 200 is formed on the dielectric substrate 205. The dielectric substrate 205 may be a PCB, and of course, the dielectric substrate 205 may also be a glass substrate, a plastic substrate, etc. In this example, by disposing the PCB on the first surface of the reflective structure 12, for example, tightly attached to the first surface of the reflective structure 12, the design freedom of the horizontal polarization unit 2 may be improved.

[0071] The other structures of the fourth example can adopt the same structure as the third example, so they will not be repeated here.

[0072] In some examples, the vertical polarization unit 1 of the disclosed embodiment includes not only the above-mentioned single-arm oscillator 11 and the reflection 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 reflection structure 12, and the second core is connected to the single-arm oscillator 11 through a second via hole penetrating the reflection 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 reflection structure 12, so space can be saved.

[0076] In some examples, the omnidirectional indoor antenna can be a transceiver antenna, that is, it can realize both the transmission of electromagnetic wave signals and the reception of electromagnetic wave signals. Of course, for the omnidirectional indoor antenna, it 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 filtering unit. The antenna in the communication device can be used as a transmitting antenna or a receiving antenna. Among them, the transceiver unit may include a baseband and a receiving end. 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 filtering unit, the power amplifier, the signal amplifier, and the radio frequency transceiver and then transmitted to the receiving end in the transceiver unit. The receiving end can be, for example, a smart gateway.

[0077] Furthermore, the RF transceiver is connected to the transceiver unit, and is used to modulate the signal sent by the transceiver unit, or to demodulate the signal received by the antenna and transmit it to the transceiver unit. Specifically, the RF transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate the various types of signals provided by the baseband and then send them to the antenna. The antenna receives the signal and transmits it to the receiving circuit of the RF transceiver. The receiving circuit transmits the signal to the demodulation circuit, and the demodulation circuit demodulates the signal and transmits it to the receiving end.

[0078] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, and the signal amplifier and the power amplifier are connected to a filter unit, and the filter unit is connected to at least one antenna. In the process of sending signals in the communication system, the signal amplifier is used to improve the signal-to-noise ratio of the signal output by the RF transceiver and then transmit it to the filter unit; the power amplifier is used to amplify the power of the signal output by the RF transceiver and then transmit it to the filter unit; the filter unit may specifically include a duplexer and a filter circuit, and the filter unit combines the signals output by the signal amplifier and the power amplifier and filters out the clutter before transmitting them to the antenna, and the antenna radiates the signal. In the process of receiving signals in the communication system, the antenna receives the signal and transmits it to the filter unit, and the filter unit filters out the clutter from the signal received by the antenna and then transmits it to the signal amplifier and the power amplifier, and the signal amplifier amplifies the signal received by the antenna to increase the signal-to-noise ratio; the power amplifier amplifies the power of the signal received by the antenna. The signal received by the antenna is processed by the power amplifier and the signal amplifier and then transmitted to the RF transceiver, and the RF transceiver then transmits it to the transceiver unit.
