[0035] See also Figure 1 and Figure 2 An embodiment of the utility model provides an antenna 100, comprising: a reflector 1, a first radiating portion 2 and a second radiating portion 3; the first radiating portion 2 and the second radiating portion 3 are both arranged on the side of the reflector 1 opposite to the folding direction of the folding portion 11, and are both located between two side edges opposite to each other along the length direction; wherein the first radiating portion 2 is located between the second radiating portion 3 and the edge of the reflector 1, thereby reducing the beam width of the antenna 100 and improving the antenna gain through the position coordination of the first radiating portion 2 and the second radiating portion 3.

[0036] The present embodiment provides an antenna 100 comprising a reflector 1, a first radiating portion 2, and a second radiating portion 3. The first radiating portion 2 and the second radiating portion 3 are both disposed on one side of the reflector 1, with the first radiating portion 2 positioned between the second radiating portion 3 and the edge of the reflector 1. The first radiating portion 2 and the second radiating portion 3 radiate at different frequencies. The coordinated positioning of the first radiating portion 2 and the second radiating portion 3 reduces the beam width of the antenna 100 and improves the antenna gain.

[0037] In the embodiment of the present application, the length direction of the reflector 1 is the length direction of the antenna 100. The beam width of the antenna 100 is the horizontal beam width of the antenna 100.

[0038] In some embodiments, see Figure 1 and Figure 2The reflector 1 is provided with folded portions 11 on both side edges along the length direction. The provision of the folded portions 11 can enhance the overall structural strength of the antenna 100, so that the antenna 100 can have a better horizontal beam width while ensuring strength, thereby improving the gain of the antenna 100. In other embodiments, when the length of the antenna 100 is long, in order to enhance the structural strength of the antenna 100, the folded portion 11 can be folded twice or more. For example, the reverse bending of the reflector is equivalent to increasing the radiation boundary of the backward radiation of the antenna 100, reducing the backward radiation intensity of the antenna 100, and improving the front-to-back intensity ratio.

[0039] In some embodiments, see Figure 1 and Figure 2 The height of the folded portion 11 in a direction perpendicular to the reflector 1 is 50 mm to 70 mm. For example, the height of the folded portion 11 may be 50 mm, 55 mm, 60 mm, 65 mm, or 70 mm.

[0040] In some embodiments, the radiation frequency of the first radiating portion 2 is lower than the radiation frequency of the second radiating portion 3. The two radiating portions with different radiation frequencies cooperate to narrow the horizontal beamwidth of the antenna 100 to a smaller value, thereby achieving maximum radiation gain for the antenna 100. In other embodiments, the radiation frequency of the first radiating portion 2 may be greater than the radiation frequency of the second radiating portion 3. In some embodiments, the horizontal beamwidth may be narrowed to 30-35 degrees. For example, the horizontal beamwidth may be narrowed to 30, 31, 32, 33, 34, or 35 degrees.

[0041] In some embodiments, see Figure 2 and Figure 3 The first radiating portion 2 includes at least two first radiating arrays 21; at least one first radiating array 21 is provided between the second radiating portion 3 and the longitudinal edge of the reflector 1. The two first radiating arrays 21 of the first radiating portion 2 cooperate with the second radiating portion 3 to improve the convergence of the horizontal beam width generated by the first radiating array 21 and the second radiating portion 3 in the horizontal direction. In other words, the horizontal beam width of the antenna 100 can be converged to a smaller value, thereby achieving maximum radiation gain for the antenna 100.

[0042] In some embodiments, see Figure 2 、 Figure 3 and Figure 4The second radiating portion 3 includes at least two second radiating arrays 31, which are located between the at least two first radiating arrays 21 and are parallel to the first radiating arrays 21. The cooperation between the two first radiating arrays 21 and the second radiating array 31 of the first radiating portion 2 can improve the convergence of the horizontal beam width generated by the first radiating arrays 21 and the second radiating array 31 in the horizontal direction. In other words, the horizontal beam width of the antenna 100 can be converged to a smaller degree, thereby achieving maximum radiation gain for the antenna 100.

[0043] In some embodiments, see Figure 1 and Figure 2 First radiation boundaries 4 are provided on opposite sides of the reflector 1; two second radiation boundaries 5 are provided between the two first radiation boundaries 4; and the two second radiation boundaries 5 are provided on opposite sides of the second radiating portion 3 along the length of the reflector 1. The first radiation boundary 4 can reduce the lateral radiation intensity of the first radiating array 21. For example, the lateral direction is the horizontal direction perpendicular to the length of the antenna 100, which improves the convergence of the horizontal beamwidth of the first radiating array 21, that is, the horizontal beamwidth of the antenna 100 can be converged to a smaller degree, thereby achieving maximum radiation gain for the antenna 100. The second radiation boundary 5 can further reduce the lateral radiation intensity of the second radiating array 31. For example, the lateral direction is the horizontal direction perpendicular to the length of the antenna 100, which further improves the convergence of the horizontal beamwidth of the second radiating array 31, that is, the horizontal beamwidth of the antenna 100 can be converged to a smaller degree, thereby achieving maximum radiation gain for the antenna 100.

[0044] In some embodiments, see Figure 2 and Figure 4 The two second radiation arrays 31 are symmetrically distributed on both sides of the symmetry axis of the reflector 1 along the length direction.

[0045] In some embodiments, see Figure 2 and Figure 4 A third radiation boundary 6 is provided at the position where the axis of symmetry in the longitudinal direction of the reflector 1 is located; a portion and another portion of the second radiation portion 3 are symmetrically distributed on both sides of the third radiation boundary 6. Exemplarily, a second radiation array 31 may be symmetrically distributed on both sides of the third radiation boundary 6. The presence of the third radiation boundary 6 can further reduce the lateral radiation intensity of the second radiation array 31. Exemplarily, the lateral direction is the horizontal direction perpendicular to the longitudinal direction of the antenna 100, further improving the convergence of the horizontal beam width of the second radiation array 31, that is, the beam width of the antenna 100 in the horizontal direction can be converged to a smaller degree, so that the antenna 100 can obtain the maximum radiation gain.

[0046] In some embodiments, see Figure 1 and Figure 2 The reflector 1 is provided with first radiation boundaries 4, symmetrically distributed along the axis of symmetry of the reflector 1, on both sides thereof. The height of the first radiation boundaries 4 in a direction perpendicular to the reflector 1 is 50 mm to 70 mm. The first radiation portion 2 includes two first radiation arrays 21, and the second radiation portion 3 includes two second radiation arrays 31. The two second radiation arrays 31 are located between the two first radiation arrays 21. Second radiation boundaries 5 are provided on opposite sides of the two second radiation arrays 31, with a height of 15 mm to 30 mm in a direction perpendicular to the reflector 1. A third radiation boundary 6 is provided between the two second radiation arrays 31, and the two second radiation boundaries 5 are symmetrical with respect to the third radiation boundary 6. For example, the height of the first radiation boundary 4 can be 50 mm, 55 mm, 60 mm, 65 mm, or 70 mm; the height of the second radiation boundary 5 can be 15 mm, 20 mm, 25 mm, 28 mm, or 30 mm.

[0047] In an embodiment of the present application, the second radiation boundary 5 can reduce the lateral radiation intensity of the second radiation array 31, so that more radiation is reflected back and concentrated within a horizontal beam width, further improving the convergence of the horizontal beam width of the second radiation array 31; the first radiation boundary 4 can reduce the lateral radiation intensity of the first radiation array 21, so that more radiation is reflected back and concentrated within a horizontal beam width, further improving the convergence of the horizontal beam width of the first radiation array 21; further, the radiation reflected and concentrated by the radiation boundary of the first radiation array 21 and the second radiation array 31 can further converge the horizontal beam width of the antenna 100 to a smaller degree. For example, the horizontal beam width can converge to 33 degrees, so that the antenna 100 can obtain maximum radiation gain.

[0048] In some embodiments, the first radiation array 21 is a low-frequency array, and the second radiation array 31 is a high-frequency array.

[0049] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4The inter-column spacing of the first radiation array 21 is 250-300mm; the first radiation array 21 includes at least two first radiation units 211, and the spacing between two adjacent first radiation units 211 is 250-300mm; the inter-column distance of the second radiation array 31 is 115-140mm; the second radiation array 31 includes at least two second radiation units 311, and the spacing between two adjacent second radiation units 311 is 125-150mm; the third radiation boundary 6 includes at least two sub-radiation boundaries 61, the length of the sub-radiation boundary 61 is 50mm-80mm, and the height is 35-50mm; wherein, a second radiation unit 311 is symmetrically arranged on both sides of each sub-radiation boundary 61.

[0050] In some embodiments, the first radiating array 21 is a low-frequency array, and the second radiating array 31 is a high-frequency array; the first radiating element 211 is a low-frequency radiating element, and the second radiating element 311 is a high-frequency radiating element. The spacing between adjacent low-frequency radiating elements in the low-frequency array is twice the spacing between adjacent high-frequency radiating elements in the high-frequency array. The height of the sub-radiating element is between the first radiation boundary 4 and the second radiation boundary 5, and can simultaneously reflect the radiation generated by the first radiating array 21 and the second radiating array 31, thereby enhancing the convergence of both high-frequency and low-frequency radiation. Thus, the coordination between the low-frequency and high-frequency arrays, as well as the first radiation boundary 4, the second radiation boundary 5, and the third radiation boundary 6, enables the antenna 100 to converge to a smaller horizontal beamwidth. This allows the antenna 100 to effectively overcome multipath and co-channel interference, thereby achieving greater radiation gain and better communication performance.

[0051] For example, the inter-column spacing of the first radiating array 21 can be 250 mm, 260 mm, 270 mm, 280 mm, 290 mm, or 300 mm; the distance between two adjacent first radiating elements 211 can be 250 mm, 260 mm, 270 mm, 280 mm, 290 mm, or 300 mm. The inter-column spacing of the second radiating array 31 can be 115 mm, 120 mm, 125 mm, 130 mm, 135 mm, or 140 mm; the distance between two adjacent second radiating elements 311 can be 125 mm, 130 mm, 135 mm, 140 mm, 145 mm, or 150 mm. The length of the sub-radiating boundary 61 can be 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, or 80 mm, and the height of the sub-radiating boundary 61 can be 35 mm, 38 mm, 40 mm, 45 mm, 48 mm, or 50 mm.

[0052] In some embodiments, see Figure 3 and Figure 4, two radiating units opposite to each other on the two first radiating arrays 21 are configured to be connected through a first power divider 7 and form a third radiating unit; two radiating units opposite to each other on the two second radiating arrays 31 are configured to be connected through a second power divider 8 and form a fourth radiating unit. In some embodiments, two radiating units on the same level can be connected through a power divider with equal amplitude and phase, and every two radiating units connected through a power divider can be regarded as the same unit. That is, two radiating units at the same level (the same level, i.e., the same horizontal plane) but in different radiating arrays can also form a new radiating unit through a power divider; two radiating units at the same level and in the same radiating array can also form a new radiating unit through a power divider. When the radiating units are at the same level, the radiation and phase of the power divider used are the same.

[0053] In some embodiments, when radiating elements are located at different levels, the radiance and phase of the power dividers used can be the same or different. For example, the radiance and phase of the power dividers used by two radiating elements at a first level can be the same as or different from the radiance and phase of the power dividers used by two radiating elements at a second level. It will be understood that two radiating elements at corresponding positions in two radiating arrays at the same level can both use the same power divider to form a new radiating element.

[0054] In some embodiments, two corresponding radiating elements on the two first radiating arrays 21 can be combined into a third radiating element using a first power divider 7, and the connected third radiating elements can form a new radiating array. Simultaneously, two corresponding radiating elements on the two second radiating arrays 31 can be combined into a fourth radiating element using a second power divider 8, and the connected fourth radiating elements can form a new radiating array. The formation of the two new radiating arrays can narrow the horizontal beamwidth of the antenna 100, for example, to 33 degrees. This allows the antenna 100 to effectively overcome multipath and co-channel interference, thereby achieving greater radiation gain and better communication performance.

[0055] In some embodiments, electronic device 1000 includes antenna 100 according to any of the above-described solutions. This reduces the horizontal beamwidth of antenna 100 within electronic device 1000 to a smaller value, for example, to 33 degrees, enabling greater radiation gain. Furthermore, the use of narrow-beam antenna 100 in electronic device 1000 can effectively overcome multipath and co-channel interference, achieving better communication performance. Electronic device 1000 can be a mobile communication device or a satellite communication device. For example, electronic device 1000 can be a 5G mobile phone.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
