[0027] The present application provides an antenna. Figure 2 As shown, the antenna of this embodiment includes a bottom plate 10, a first antenna 30, and a second antenna 40. A reflector 20 is disposed on the bottom plate 10. The first antenna 30 includes a first substrate 301 and a first patch 302. The first substrate 301 is disposed on the end surface of the reflector 20 away from the bottom plate 10, and the first patch 302 is disposed on the end surface of the first substrate 301 away from the bottom plate 10. The second antenna 40 is disposed on the end surface of the bottom plate 10 facing the first antenna 30, and is spaced apart from the reflector 20.

[0028] In an optional embodiment, a reflector 20 is provided on the bottom plate 10, and the reflector 20 can greatly improve the efficiency of the upper hemisphere of the first antenna 30, wherein the reflector 20 can be a metal plate, which is not specifically limited in this application, and preferably, the thickness of the reflector 20 is less than that of the bottom plate 10. The bottom plate 10 has a certain thickness, and the bottom plate 10 surrounds the reflector 20, wherein the bottom plate 10 and the reflector 20 can also be formed in one piece, and the bottom plate 10 can be set as an insulating plate, which is not specifically limited in this application. And by providing a first substrate 301 on the end surface of the reflector 20 away from the bottom plate 10, and providing a first patch 302 on the first substrate 301, the first substrate 301 and the first patch 302 constitute the first antenna 30. It should be noted that the first patch 302 is attached to the first substrate 301 so that the first patch 302 is closely attached to the first substrate 301 to form the first antenna 30. The first antenna 30 can be a ceramic antenna, so that the first antenna 30 has good mechanical strength and stability, and the first patch 302 can also be fixed on the first substrate 301 by other fixing methods, which is not specifically limited in this application. The radiation frequency band of the first antenna 30 is 2460-2500MHZ. Further, a second antenna 40 is arranged on the end surface of the bottom plate 10 facing the first antenna 30, so that the first antenna 30 and the second antenna 40 are integrated into one, and the topological structure of the first antenna 30 and the second antenna 40 is reconstructed. It can be understood that antennas have certain volume requirements, and there are other antennas in products such as mobile terminals. Due to the miniaturization of terminal products, there is a lack of space for simultaneously discretely arranging multiple antennas. By integrating the first antenna 30 and the second antenna 40, the problem that multiple antennas cannot coexist due to limited space caused by product miniaturization is improved, the communication performance of the product is improved, and the cost is saved.

[0029] In the above manner, by arranging the first substrate 301 on the end surface of the reflector 20 away from the bottom plate 10, and arranging the first patch 302 on the first substrate 301, so that the first substrate 301 and the first patch 302 constitute the first antenna 30, and arranging the second antenna 40 on the end surface of the bottom plate 10 facing the first antenna 30, the first antenna 30 and the second antenna 40 are integrated into one, and the topological structure of the first antenna 30 and the second antenna 40 is reconstructed, thereby improving the problem that multiple antennas cannot coexist due to limited space due to product miniaturization, improving the communication performance of the product, and saving the production cost of the product.

[0030] In an optional embodiment, if Figure 3 and Figure 4As shown, the reflector 20 and the second antenna 40 are in the same plane, and the second antenna 40 is arranged around the reflector 20. Therefore, by arranging the reflector 20 on the bottom plate 10, and arranging the second antenna 40 on the bottom plate 10 in the same plane as the reflector 20, and the second antenna 40 surrounds the reflector 20. The volume of the antenna can be made smaller, so that it is convenient to install the antenna in a terminal product with limited space, so that it is convenient to install other antennas in the terminal product, and the layout capability of installing multiple antennas in the terminal product is improved, thereby improving the problem that multiple antennas cannot coexist in a limited space due to product miniaturization, and improving the communication performance of the product. Among them, the second antenna 40 can also partially surround the reflector 20, and this application does not make specific restrictions here.

[0031] In an optional embodiment, if Figure 3 As shown, the antenna further includes a third antenna 50, and the third antenna 50 includes a second substrate 501 and a second patch 502. The second substrate 501 is arranged on the end surface of the first patch 302 away from the bottom plate 10, and the second patch 502 is arranged on the end surface of the second substrate 501 away from the first patch 302. Therefore, by arranging the second substrate 501 on the end surface of the first patch 302 of the first antenna 30, and arranging the second patch 502 on the end surface of the second substrate 501 away from the first patch 302, the second substrate 501 and the second patch 502 constitute the third antenna 50. Among them, the second patch 502 is attached to the second substrate 501, so that the second patch 502 is closely attached to the second substrate 501 to constitute the third antenna 50. The third antenna 50 can be a ceramic antenna, so that the third antenna 50 has good mechanical strength and stability, and the second patch 502 can also be fixed on the second substrate 501 by other fixing methods, which is not specifically limited in this application. The radiation frequency band of the third antenna 50 is 1610-1625 MHZ. By integrating the first antenna 30, the second antenna 40 and the third antenna 50, the topological structure of the first antenna 30, the second antenna 40 and the third antenna 50 is reconstructed, further improving the problem that multiple antennas cannot coexist in limited space due to product miniaturization, and improving the communication performance of the terminal product.

[0032] In an optional embodiment, if Figure 3 and Figure 7 As shown, the second antenna 40 includes an NFC antenna 401 or a SUB 6G antenna 402 disposed on the bottom plate 10. Therefore, the second antenna 40 can be configured as the NFC antenna 401 or the SUB 6G antenna 402. For example, when the second antenna 40 is configured as the NFC antenna 401, the NFC antenna 401 is located on the end surface of the bottom plate 10 facing the first antenna 30, and the NFC antenna 401 is completely surrounded by the reflective plate 20. Figure 8As shown, according to the Smith circle, the inductance of the NFC antenna 401 at 13.56MHZ is 1.76uH, which meets the requirement that the inductance of the NFC antenna 401 is within the range of 1-2uH. When the second antenna 40 is set as the SUB 6G antenna 402, the SUB 6G antenna 402 is located on the end surface of the bottom plate 10 facing the first antenna 30, and the SUB6G antenna 402 is partially surrounded by the reflector 20. The second antenna 40 utilizes the plane of the reflector 20, is designed on the same plane as the reflector 20, and the second antenna 40 is in the area adjacent to the reflector 20. Among them, the second antenna 40 can also be integrated with the first antenna 30 using other antennas, and this application is not specifically limited here. It should be noted that the second antenna 40 is set as the NFC antenna 401 or the SUB 6G antenna 402, which can increase the integration performance of the antenna, thereby improving the diversity of antenna production.

[0033] Furthermore, if Figure 3 As shown, the projections of the first antenna 30 and the third antenna 50 are located inside the second antenna 40. Therefore, the first antenna 30, the third antenna 50 and the second antenna 40 having a certain volume can be integrated into one, and the topological structures of the first antenna 30, the second antenna 40 and the third antenna 50 are reconstructed, so that the integrated first antenna 30, the second antenna 40 and the third antenna 50 can be installed in a limited space in the terminal product, and the integrated first antenna 30, the second antenna 40 and the third antenna 50 have good performance, which improves the problem that multiple antennas cannot coexist due to limited space caused by the miniaturization of the terminal product, greatly saves the production cost of the terminal product, and improves the communication performance of the product. In other embodiments, the third antenna 50 may not be set on the first antenna 30. For example, when the space of the terminal product is insufficient to set the third antenna 50, only the first antenna 30 and the second antenna 40 are integrated on the bottom plate 10, thereby improving the communication performance of the terminal product. Other antennas may also be arranged on the second patch 502 on the third antenna 50, so that the layout capability of the antenna installed on the terminal product is improved, thereby providing more space when other devices are installed on the terminal product, thereby improving the performance of the terminal product. This application does not make specific limitations here.

[0034] In an alternative embodiment, such as Figure 5 and Figure 6As shown, a first wire 601 is provided on the bottom plate 10, passing through the first substrate 301 and conducting with the first patch 302. The first wire 601 is provided with a feeding port 80 on the bottom plate 10, and a first feeding center conductor is provided inside the first wire 601, so that the first wire 601 passes through the bottom layer, the first substrate 301 and directly conducts with the first patch 302. Further, a second wire 602 is provided on the bottom plate 10, passing through the first substrate 301, the first patch 302, the second substrate 501 and conducting with the second patch 502, and the first wire 601 and the second wire 602 are arranged in parallel. The second wire 602 is provided with a feeding port 80 on the bottom plate 10, and a second feeding center conductor is provided inside the second wire 602, so that the second conductor passes through the bottom layer, the first substrate 301, the first patch 302, the second substrate 501 and directly conducts with the second patch 502. It should be noted that the first conductive wire 601 and the second conductive wire 602 are arranged in parallel, and the feeding form of the first patch 302 and the second patch 502 is coaxial feeding.

[0035] In an optional embodiment, if Figure 3 As shown, an adjustment component 70 is provided on the end surface of the second patch 502 away from the bottom plate 10. That is, by providing the adjustment component 70 on the second patch 502, the frequency of the third antenna 50 can be adjusted to improve the performance of the antenna, thereby adjusting the communication performance of the terminal product. In another embodiment, as Figure 2 As shown, when only the first antenna 30 and the second antenna 40 are set on the base plate 10, the adjustment component 70 can be set on the first patch 302 to adjust the frequency of the first antenna 30 and improve the performance of the antenna. This application does not make specific limitations here.

[0036] In an optional embodiment, if Figure 1 and Figure 7 As shown, at least one feeding port 80 is provided on the second antenna 40. For example, when the second antenna 40 is set as an NFC antenna 401, the NFC antenna 401 is completely surrounded by the reflector 20, and the two ends of the NFC coil pass through the bottom plate 10 and are connected together on the end surface of the bottom plate 10 away from the first antenna 30, so that the NFC coil is turned on, thereby forming the NFC antenna 401, and the end of the NFC coil away from the reflector 20 passes through the end of the bottom plate 10 as the feeding port 80. In other embodiments, when the second antenna 40 is set as a SUB 6G antenna 402, the SUB 6G antenna 402 is partially surrounded by the reflector 20, and the SUB 6G antennas 402 are respectively distributed at the four corners around the bottom plate 10, and each SUB 6G antenna 402 at the four corners is provided with a feeding port 80. This application is not specifically limited here, thereby increasing the diversity of antenna products and the performance of terminal products.

[0037] In the above manner, by arranging the first substrate 301 on the end face of the reflector 20 away from the bottom plate 10, arranging the first patch 302 on the first substrate 301 to form the first antenna 30, and arranging the second antenna 40 on the end face of the bottom plate 10 facing the first antenna 30, the topological structure of the first antenna 30 and the second antenna 40 can be reconstructed, thereby improving the problem that multiple antennas cannot coexist in a limited space due to product miniaturization, and improving the communication performance of the product. By arranging the second antenna 40 and the reflector 20 in the same plane, and the second antenna 40 surrounding the reflector 20, the volume of the antenna can be made smaller, so that it is convenient to install the antenna in a terminal product with limited space and to install other antennas in the terminal product. By arranging the second substrate 501 on the end face of the first patch 302 away from the bottom plate 10, and arranging the second patch 502 on the end face of the second substrate 501 away from the first patch 302 to form the third antenna 50, the topological structure of the first antenna 30, the second antenna 40 and the third antenna 50 can be reconstructed, and the layout capability of the antenna in the terminal product and the communication performance of the terminal product are improved. By setting the second antenna 40 as an NFC antenna 401 or a SUB 6G antenna 402, the integration performance of the antenna can be increased, thereby improving the diversity of antenna production. By locating the projections of the first antenna 30 and the third antenna 50 inside the second antenna 40, the integrated first antenna 30, the second antenna 40 and the third antenna 50 can be installed in a limited space in the terminal product, thereby saving the production cost of the terminal product. By arranging the first wire 601 and the second wire 602 on the bottom plate 10, and the first wire 601 and the second wire 602 are arranged in parallel, the feeding form of the first patch 302 and the second patch 502 is coaxial feeding. By arranging at least one feeding port 80 on the second antenna 40, the diversity of the antenna and the performance of the terminal product are increased.
