[0038] First, Figure 1 A three-dimensional diagram of an omnidirectional indoor antenna according to an embodiment of the present disclosure; Figure 2 A top view of the omnidirectional indoor antenna according to an embodiment of the present disclosure; Figure 3 is a partial cross-sectional view of the omnidirectional room antenna according to an embodiment of the present disclosure; Figure 1-3As 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. In particular, in the embodiment of the present disclosure, the reflection structure 12 at least includes a first reflection component 121, and the first reflection component 121 includes a plurality of main body parts 1211 arranged in sequence along the circumference thereof, and a radiation structure 21 is arranged on a main body part 1211, for example: the main body part 1211 is arranged one-to-one with the radiation structure 21. The radiation structure 21 includes at least one radiation patch, and the outer contour of the main body 1211 matches the outer contour of the radiation patch. For example, the contour of the radiation patch is a rectangle, and the contour of the main body 1211 is also a rectangle, and the sides of the two are arranged one by one.
[0039] Reference Figure 1 , Figure 1In the example, the single-arm oscillator 11 in the vertical polarization unit 1 adopts a conical column 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 the embodiment of the present disclosure, only the radiation structure 21 including a double-layer radiation patch is taken as an example. For the convenience of description, the one of the two layers of radiation patches close to the main body 1211 is called the first radiation patch 201, and the other is called the second radiation patch 202. In the embodiment 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 the same time, the main body 1211 and the outer contour of the first radiation patch 201 / the second radiation patch 202 located thereon are adapted, that is, the distance between the edge of the main body 1211 and the edge of the first radiation patch 201 / the second radiation patch 202 can be relatively shortened, so that the high pitch angle (for example: Theta ≥ 60°) gain of the horizontal polarization unit 2 can be improved, so that the edge currents of the first radiation patch 201 and the second radiation patch 202 are as symmetrical as possible, and the overall radiation pattern of the horizontal polarization unit 2 can be improved. In the embodiment of the present disclosure, taking the radiation structure 21 including the first radiation patch 201 and the second radiation patch 202 as an example, the spacing 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 through a support. In this case, the main body 1211 serves as a reference electrode of the radiation structure 21. The medium between the main body 1211 and the first radiation patch 201 is air. In this case, a double-layer radiation patch is used as a radiator to improve gain and bandwidth. The support can be a nylon column, a plastic buckle, etc., which are not listed here. The fixing member and the support can be made of the same material.
[0040] Of course, the first radiation patch 201 in the radiation structure 21 may also be disposed on a dielectric substrate and fixed on the main body 1211 through the dielectric substrate, wherein the dielectric substrate may be a PCB.
[0041] In one example, the orthographic projection of the second radiation patch 202 on the plane where the main body 1211 is located is located within the orthographic projection of the first radiation patch 201 on the plane where the main body 1211 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 main body 1211 is located covers the orthographic projection of the first radiation patch 201 on the plane where the main body 1211 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.
[0042] 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 a circle, an ellipse, a polygon or a special shape. When the shapes of the first radiation patch 201 and the second radiation patch 202 are polygonal, the shapes of both may be a rectangle, a square, a hexagon, a trapezoid, etc. In the embodiment of the present disclosure, only the first radiation patch 201 and the second radiation patch 202 are rectangular as an example, and it should be understood that at this time, the shape of the main body 1211 is also a rectangle.
[0043] In some examples, the horizontal polarization unit 2 in the embodiment of the present disclosure includes not only the above-mentioned radiation structure 21, but also includes 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 radiation 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 radiation structure 21 for radiation.
[0044] 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.
[0045] 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.
[0046] In some examples, Figure 4Schematic 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 first core 221 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 1212, the portion of the first connection end where the first dielectric layer 222 is exposed extends from the second surface side of the reflective structure 1212 to the first surface side through the first via hole penetrating the reflective structure 1212, and the exposed core 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.
[0047] When the feeding component 22 uses the first coaxial cable, the first core 221 of the first coaxial cable is connected to the first radiation 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 spacing between the first radiation patch 201201 and the second radiation patch 202202 in the radiation structure 2121, 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.
[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. 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 on the second surface side 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 network 23, so that the overall structure of the antenna is simple.
[0049] In some examples, 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 reflection structure 12, but also a second coaxial cable for feeding the single-arm oscillator 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 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 that passes through the reflection structure 12. In this case, the second reference electrode layer is connected to the reflection 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 arranged in the cone disk structure of the reflection structure 12, so space can be saved.
[0050] In some examples, continue to refer to Figure 1 The omnidirectional room antenna in the embodiment of the present disclosure not only includes the above-mentioned structure, but also includes an antenna cover, and the vertical polarization unit 1 and the horizontal polarization unit 2 are located in the antenna cover. Specifically, the antenna cover may include a first part and a second part, and 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. Among them, the reflection structure 12 is fixed to the bottom plate of the first part of the antenna cover, for example, the reflection structure 12 and the bottom surface of the first part of the antenna cover are fixed by bolts. A limiter is set 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. In one example, the antenna cover can be made of plastic resin material.
[0051] In some examples, no matter which of the above structures is adopted by 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. In the embodiment of the present disclosure, by reasonably setting the number of the radiation structures 21, the gain can be effectively improved, and the circularity of the radiation pattern can be made better.
[0052] In order to make the specific structure of the reflection structure 12 in the omnidirectional room antenna of the embodiment of the present disclosure clearer, and the corresponding relationship between the reflection structure 12 and the radiation structure 21, a description will be given below in combination with specific examples.
[0053] The first example: Reference 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 bodies 1211 and a filling portion 1212 connected between the main bodies 1211. The second reflective component 122 is connected to the main body 1211 and is arranged opposite to the single-arm vibrator 11. Among them, the main body 1211 is a rectangle and the filling portion 1212 is a triangle. The angle between the extended surface of the plane where the main body 1211 is located and the extended surface of the plane where the second reflective component 122 is located is a first dihedral angle, and the angle between the extended surface of the plane where the filling portion 1212 is located and the extended surface of the plane where the second reflective component 122 is located is a second dihedral angle, and the first dihedral angle is not equal to the second dihedral angle. In other words, the plane where the main body 1211 is located and the plane where the filling portion 1212 is located are not in the same plane. The main body 1211 and the first radiation patch 201 / the second radiation patch 202 of the radiation structure 21 located thereon are both rectangular. At this time, the size of the first radiation patch 201 / the second radiation patch 202 can be adjusted to reduce the distance between the first radiation patch 201 / the second radiation patch 202 and the edge of the main body 1211, and the corresponding settings can make the edge currents of the first radiation patch 201 and the second radiation patch 202 as symmetrical as possible, thereby improving the overall radiation pattern of the horizontal polarization unit 2.
[0054] In some examples, the first dihedral angle formed by the extended surface of the plane where each main body 1211 is located and the plane where the second reflective component 122 is located are equal. The second dihedral angle formed by the extended surface of the plane where each filling part 1212 is located and the plane where the second reflective component 122 is located are equal. In this case, it is convenient to design the structure of the first reflective component 121. Further, the size of each main body 1211 can be designed to be the same, and the size of each filling part 1212 can be designed to be the same.
[0055] In some examples, the main body 1211 and the first radiation patch 201 and the second radiation patch 202 thereon are arranged in parallel, so as to facilitate feeding the first radiation patch 201 .
[0056] In some examples, Figure 5 FIG. 1 is a schematic diagram of a first reflective component 121 of a first example of an omnidirectional room antenna according to an embodiment of the present disclosure; Figure 5 As shown, the first reflective component 121 also includes a plurality of connecting parts 1213 connected in sequence, one connecting part 1213 is connected to one main body 1211, and the interconnected connecting parts 1213 and the main body 1211 are an integral structure; 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 bottom plate of the radome to achieve the fixation of the reflective structure 12 and the radome.
[0058] Specifically, the fixing component 123 may include a first fixing portion 123a and a second fixing portion 123b, wherein the first fixing portion 123a is connected to the main body portion 1211, and the second fixing portion 123b is connected to the filling portion 1212. The first fixing portion 123a and the second fixing portion 123b are both arc-shaped, and the arcs of the first fixing portions 123a and the arcs of the second fixing portions 123b form a circle. The first fixing portion 123a and the second fixing portion 123b are both arranged on the bottom plate of the antenna cover and fixedly connected to the bottom plate of the antenna cover, for example, by screws, snaps, etc. That is to say, the outer contour of the positive projection of the reflective structure 12 composed of the first reflective component 121, the second reflective component 122 and the fixing component 123 on the plane where the bottom plate of the antenna cover is located is a circle.
[0059] by Figure 1 Take the omnidirectional indoor antenna shown as an example. Figure 6 The directional diagram of the horizontal polarization unit 2 of the first example of the omnidirectional room antenna according to the embodiment of the present disclosure; Figure 7 FIG. 1 is a standing wave diagram of the horizontal polarization unit 2 of the first example of the omnidirectional room antenna of the embodiment of the present disclosure; Figure 6 and 7 As shown, the performance of the omnidirectional indoor antenna is better.
[0060] Second example: Figure 8 FIG. 2 is a schematic diagram of the structure of a second example of the omnidirectional room antenna according to an embodiment of the present disclosure; Figure 8 As shown, the first radiation patch 201 and the second radiation patch 202 in the radiation structure 21 in this example are rectangular, and the main body 1211 of the first reflective component 121 is also rectangular. The second reflective component 122, which is different from the first example, is a whole-surface structure, and the second reflective component 122 and the main body 1211 are not an integral structure. When there are five main bodies 1211, the outer contour of the second reflective component 122 is a pentagon, and one side is shared with one side of a main body 1211. The rest of the structures in the second example are the same as those in the first example, so they are not repeated here.
[0061] The third example: Fig. 9 FIG. 1 is a schematic structural diagram of a third example of an omnidirectional room antenna according to an embodiment of the present disclosure; Fig. 9As shown, in this example, the auxiliary component 13 can be connected to the side of the first reflective component 121 away from the second reflective component 122 on the basis of the first example or the second example structure. The tangent line of any point on the auxiliary component 13 intersects with the extension surface of the plane where the main body 1211 is located, and / or, the tangent line of any point on the auxiliary component 13 intersects with the extension surface of the plane where the filling part 1212 is located. For example: the auxiliary component 13 can be arranged vertically relative to the plane where the second radiation component is located. Further, the auxiliary component 13 can be a cylindrical structure. It can be seen that by adding the auxiliary component 13, it is equivalent to extending the length of the first reflective component 121 component on the basis of the first example and the second example, and increasing the area of the reflective component, but it should be noted that due to the increase in the area of the reflective component, the size of the first radiation patch 201 and the second radiation patch 202, the height relative to the main body 1211, and the position of the feeding point all need to be adjusted accordingly to meet the performance of the antenna.
[0062] Fourth example: Fig.10 FIG. 4 is a schematic diagram of the structure of a fourth example of the omnidirectional room antenna according to an embodiment of the present disclosure; Fig.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 portions 1211 of the first reflective component 121 needs to be able to be spliced with the main portion 1211 to form a conical structure. In this case, the first reflective component 121 has no edges, and the edges of the first radiation patch 201 and the second radiation patch 202 of the radiation structure 21 are equivalent to having no spacing from the edges of the first reflective component 121, so that the edge currents of the first radiation patch 201 and the second radiation patch 202 can be as symmetrical as possible, and the overall radiation pattern of the horizontal polarization unit 2 can be improved. It should be noted here that the shape, size, height of the oscillators of the first radiation patch 201 and the second radiation patch 202 relative to the reflective structure 12, the spacing between the first radiation patch 201 and the second radiation patch 202, and the position of the feeding point can all be changed to match the performance requirements under the structure.
[0063] The fifth example: Fig.11 FIG. 4 is a schematic diagram of the structure of the fifth example of the omnidirectional room antenna according to the embodiment of the present disclosure; Fig.11As shown, in this example, the first reflective component 121 is a planar structure, that is, the filling portion 1212 between the multiple main portions 1211 of the first reflective component 121 needs to be able to be spliced with the main portion 1211 to form a planar structure. In this case, the horizontal polarization unit 2 uses the reflective structure 12 as a reference electrode, and the phenomenon that the azimuth angle of the directional diagram caused by various asymmetric structures has a large gain difference within the range of 360° at a certain pitch angle is eliminated. However, since the main radiation direction angle of the horizontal polarization unit 2 will become smaller, under this structure, the shape, size, height between the oscillators of the first radiation patch 201 and the second radiation patch 202 and the reflective structure 12, the spacing between the first radiation patch 201 and the second radiation patch 202, and the position of the feeding point can all be changed to match the performance requirements under this structure.
[0064] The sixth example: Fig.12 FIG. 6 is a schematic structural diagram of a sixth example of an omnidirectional room antenna according to an embodiment of the present disclosure; Fig.12 As shown, in this example, the reflection structure 12 includes a first reflection structure 12 and a second reflection component 122, the second reflection component 122 is connected to the first reflection component 121, and is arranged opposite to the single-arm oscillator 11; the first reflection structure 12 only includes a plurality of main body parts 1211 connected in sequence; and the planes where each main body part 1211 is located form a third dihedral angle with the plane where the first reflection component 121 is located, and the size of each third dihedral angle is equal. For example: the planes where the main body part 1211 is located form a third dihedral angle of 90° with the plane where the first reflection component 121 is located. That is to say, each main body part 1211 is perpendicular to the bottom plate of the antenna cover. In the example, the first radiation patch 201 and the second radiation patch 202 of the radiation structure 21 are rectangular, and the main body 1211 is also rectangular. In this case, the boundary conditions in each radiation structure 21 of the horizontal polarization unit 2 are consistent, and the spatial isolation between the two adjacent units is increased, reducing the respective coupling effects. Under this structure, the shape, size, height between the oscillators of the first radiation patch 201 and the second radiation patch 202 and the reflection structure 12, the spacing between the first radiation patch 201 and the second radiation patch 202, and the position of the feeding point can all be changed to match the performance requirements under this structure.
[0065] 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 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 22 together constitute a MIMO antenna.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] In some examples, the signal amplifier may include various types of signal amplifiers, such as a low noise amplifier, which is not limited herein.
