Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] Currently, traditional single-beam and wide-beam base station antennas are insufficient to meet the communication capacity requirements of densely populated areas.
[0030] Based on this, the dual-beam antenna and communication device provided by this utility model embodiment can effectively alleviate the technical problem that traditional antennas are unable to meet the communication capacity requirements of densely populated areas.
[0031] To facilitate understanding of this embodiment, a dual-beam antenna disclosed in this utility model embodiment will first be described in detail.
[0032] In one possible implementation, the present invention provides a dual-beam antenna, specifically, the dual-beam antenna includes: a substrate, and a radiating array disposed on the substrate.
[0033] The radiating array includes at least one first array and at least one second array, the first array and the second array include different numbers of radiating elements, and the horizontal plane wavelengths of the first array and the second array are different; at least one first array and at least one second array are arranged in combination along a first direction of the substrate to form a dual-beam antenna array.
[0034] For ease of understanding, the above-mentioned substrate is described as being elongated, and in this embodiment of the invention, the first direction is defined as the direction along the long side of the substrate.
[0035] like Figure 1 The block diagram of a dual-beam antenna shown includes a substrate 10, and a first array 100 and a second array 200 disposed on the first substrate. To facilitate differentiation between the first array 100 and the second array 200, the example given is that the first array includes a greater number of radiating elements than the second array. Figure 1 In the first array 100, the area is larger than the area of the second array 200.
[0036] In actual use, the number of radiation units included in the first array and the second array can be set according to the actual use situation, and this embodiment of the utility model does not limit this.
[0037] Furthermore, when the aforementioned at least one first array and at least one second array are arranged in combination along the first direction of the substrate, the first array and the second array can be arranged alternately in sequence, or a certain number of first arrays and a certain number of second arrays can be arranged alternately, wherein, Figure 1 The illustration only shows an implementation with two first arrays and two second arrays arranged alternately. In other implementations, the number of first arrays and second arrays can be set according to actual usage, and different numbers of first arrays and second arrays can be arranged alternately to form a dual-beam antenna array. The specific arrangement can be set according to actual usage, and this embodiment of the invention does not limit this.
[0038] The dual-beam antenna provided in this embodiment includes: a substrate and a radiating array disposed on the substrate; wherein the radiating array includes at least one first array and at least one second array, the first array and the second array include different numbers of radiating elements, and the horizontal plane wavelengths of the first array and the second array are different; at least one first array and at least one second array are arranged in combination along a first direction of the substrate to form a dual-beam antenna array. The dual-beam antenna array formed by the combination of the above-mentioned first array and second array is more likely to broaden or narrow the horizontal plane wavelength, so as to improve the antenna signal coverage range and thus help meet the communication capacity requirements.
[0039] In practical use, the first array includes a first number of first radiating units and a first power divider connected to each first radiating unit; wherein the first number of first radiating units are arranged sequentially along the second direction of the substrate.
[0040] In this embodiment of the invention, the second direction is a direction perpendicular to the first direction. For example, when the first direction is along the long side of the substrate, the second direction can be along the short side of the substrate.
[0041] Furthermore, the second array includes a second number of second radiating units and a second power divider connected to each second radiating unit; wherein the second number of second radiating units are arranged sequentially along a second direction of the substrate, and the second number is less than the first number.
[0042] That is, the number of radiating elements contained in the second array is less than the number of radiating elements contained in the first array.
[0043] Furthermore, the aforementioned first number of first radiating units are divided into a first radiating unit group and a second radiating unit group; the first radiating unit group and the second radiating unit group contain the same number of first radiating units; wherein the radiating directions of the first radiating units contained in the first radiating unit group and the first radiating units contained in the second radiating unit group are 180° apart.
[0044] The corresponding second number of second radiation units are divided into a third radiation unit group and a fourth radiation unit group; the third radiation unit group and the fourth radiation unit group contain the same number of second radiation units; wherein the radiation directions of the second radiation units contained in the third radiation unit group and the second radiation units contained in the fourth radiation unit group are 180° apart.
[0045] Furthermore, in the embodiments of this utility model, the first quantity is preferably four, and the corresponding first radiation unit group includes two first radiation units, and the second radiation unit group includes two first radiation units.
[0046] Furthermore, the second quantity is preferably two, while the third radiating unit group includes one second radiating unit, and the fourth radiating unit group includes one second radiating unit.
[0047] In the first and second arrays described above, the radiating elements are grouped and arranged such that the radiating directions of the two groups of radiating elements are 180° apart. This eliminates the need to add a phase-shifting network to achieve the 180° phase-shifting function, which helps to reduce antenna costs.
[0048] Furthermore, the radiation elements contained in the first and second arrays can be the same, that is, the phase shift line lengths of the two beams are the same, which not only makes them easy to assemble, but also makes them more manufacturable and easier to promote and use.
[0049] Furthermore, for ease of understanding, Figure 2 A schematic diagram of a dual-beam antenna is shown. For ease of explanation, the example is given with four beams in the first phase and two beams in the second phase.
[0050] like Figure 2 As shown, the array includes a substrate 10, and a first array 100 and a second array 200 circled in dashed lines. The first array 100 includes four radiating elements, and the second array 200 includes two radiating elements. That is, the first array includes four first radiating elements, and the second array includes two second radiating elements.
[0051] and, Figure 2 The diagram shows the alternating arrangement of two first arrays and two second arrays.
[0052] For ease of explanation, Figure 2 In the first and second arrays, only the arrangement of the radiating elements is shown, without showing the schematic diagram of the first and second power dividers. The first and second power dividers can be set at preset positions in the corresponding first and second arrays, and this embodiment of the present invention does not limit this.
[0053] Furthermore, for ease of explanation, Figure 3 A schematic diagram of a first array is shown, wherein, Figure 3 In this example, the first array includes four first radiating elements, which will be used for illustration. Figure 3 The first radiating element 301 is circled in the middle dashed circle.
[0054] Moreover, in Figure 3 In the middle, the two first radiating units on the left form a first radiating unit group, and the two first radiating units on the right form a second radiating unit group. Furthermore, by... Figure 3 It can be seen that the radiation directions of the first radiation unit contained in the first radiation unit group and the first radiation unit contained in the second radiation unit group are 180° apart.
[0055] Furthermore, the first power divider in this embodiment of the present invention is a Butler power divider; specifically, Figure 4 A schematic diagram of a first power divider is shown, as follows: Figure 4 The structure circled in the diagram shows that the first power divider provided in this embodiment of the present invention includes a first power divider unit 401, a directional coupler 402, and a second power divider unit 403 connected in sequence.
[0056] The first power divider unit and the second power divider unit are symmetrically arranged on both sides of the directional coupler; the first radiation unit group includes a first radiation unit connected to the first power divider unit, and the second radiation unit group includes a first radiation unit connected to the second power divider unit.
[0057] Specifically, Figure 3 The diagram also shows the ports where each first radiating element connects to the first power divider, such as... Figure 3 Ports 1, 2, 3, and 4 are connected to... Figure 4 The first power divider is shown as P1, P2, P3, and P4.
[0058] further, Figure 5 A schematic diagram of a second array is shown, wherein, Figure 5 In this example, we will use the second array, which includes two second radiating elements, as an example. That is, Figure 5 In the image, the dashed lines show two second radiating units 501.
[0059] and, Figure 5 In the middle, the second radiating unit on the left forms the third radiating unit group, and the second radiating unit on the right forms the fourth radiating unit group. Furthermore, by... Figure 5 It can be seen that the radiation directions of the second radiation unit contained in the third radiation unit group and the second radiation unit contained in the fourth radiation unit group are 180° apart.
[0060] Furthermore, the second power divider in this embodiment of the present invention is also a Butler power divider; specifically, Figure 6 A schematic diagram of a second power divider is shown, as follows: Figure 6 As shown, the second power divider provided in this embodiment of the present invention includes a third power divider unit 601, a directional coupler 602 and a fourth power divider unit 603 connected in sequence.
[0061] The directional coupler of the second power divider can be the same as or different from the directional coupler of the first power divider, depending on the actual use. This embodiment of the utility model does not impose any restrictions on this.
[0062] Furthermore, the third and fourth power distribution units are symmetrically arranged on both sides of the directional coupler; the second radiation unit in the third radiation unit group is connected to the third power distribution unit, and the second radiation unit in the fourth radiation unit group is connected to the fourth power distribution unit.
[0063] in, Figure 5 The diagram also shows the ports where each second radiating unit connects to the second power divider, such as... Figure 5 Ports 5 and 6 in the diagram are connected to... Figure 6The second power divider, P5 and P6, are shown.
[0064] In practical use, based on the above Figures 2-6 In this embodiment of the present invention, since both the first power divider and the second power divider are Butler power dividers, the first array can also be called the first Butler array, and the second array can also be called the second Butler array.
[0065] and, Figure 2 In this configuration, the first Butler array has four radiating elements in the horizontal direction (the second direction mentioned above), resulting in a narrower horizontal beamwidth. The second Butler array has two radiating elements in the horizontal direction (the second direction mentioned above), resulting in a wider horizontal beamwidth. Combining the first and second Butler arrays allows for easy widening or narrowing of the horizontal beamwidth, thus improving the antenna signal coverage.
[0066] Furthermore, by Figure 3 and Figure 5 As shown, by grouping the radiating elements and making the radiating directions of the two groups of radiating elements 180° apart, the phase shifting function can be achieved without adding a 180° phase shifting module, which effectively reduces the cost of the antenna. In addition, the phase shifting line lengths of the two beams are the same, which makes them easy to assemble and has good manufacturability.
[0067] Furthermore, the aforementioned second Butler array has two radiating elements arranged in the horizontal direction, which can save the space of two radiating elements and make it easier to nest low-frequency radiating elements, thereby forming a multi-frequency dual-beam antenna array.
[0068] Furthermore, both the first and second Butler power dividers can employ a three-branch directional coupler scheme, offering advantages such as wide operating bandwidth and good beam isolation. Additionally, the power ratio of the first Butler power divider can be designed as 1:4.2:4.2:1, which provides a relatively high power ratio and results in better horizontal sidelobes for the dual-beam antenna.
[0069] Furthermore, based on the above embodiments, this utility model embodiment also provides a communication device, which includes the dual-beam antenna provided in the above embodiments.
[0070] The communication device provided in this embodiment of the present invention has the same technical features as the dual-beam antenna provided in the above embodiment, so it can also solve the same technical problems and achieve the same technical effects.
