In this embodiment, the electronic device may specifically include: the antenna comprises a plastic middle frame 10, a plurality of radio frequency antennas 11 and a plurality of millimeter wave antennas 12; the plastic middle frame 10 may include a middle frame base 101 and a frame 102, and the frame 102 is fixedly connected to the outer side of the middle frame base 101; the plurality of radio frequency antennas 11 and the plurality of millimeter wave antennas 12 are arranged around the plastic middle frame 10; the rf antenna 11 may include a first radiator 111, and a first feed 112 and a ground 113 electrically connected to the first radiator 111, where the first radiator 111 is disposed on the frame 101; the millimeter-wave antenna 12 may include a plurality of second radiators 121 distributed in an array, and a second feeder 122 electrically connected to the second radiators 121, where the second radiators 121 are disposed on the frame 102.
In practical application, the plastic middle frame 10 may be obtained by processes such as injection molding, and in order to improve production efficiency, the middle frame base 101 and the side frame 102 of the plastic middle frame 10 may be an integral structure. Specifically, the middle frame base 101 and the side frame 102 may be integrally formed by an injection molding process to achieve a fixed connection therebetween. Then, a plurality of rf antennas 11 and a plurality of millimeter wave antennas 12 are formed on the plastic middle frame 10. The process of injection molding the radio frequency antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10 together is avoided, and the radio frequency antenna 11 and the millimeter wave antenna 12 do not need to bear injection molding pressure, so that the thicknesses of the radio frequency antenna 11 and the millimeter wave antenna 12 can be thinner, and the radio frequency antenna 11 and the millimeter wave antenna 12 are not easy to break.
Specifically, the first radiator 111 of the radio frequency antenna 11 and the second radiator 121 of the millimeter wave antenna 12 may be provided in a sheet-like structure, and the thickness of the first radiator 111 and the second radiator 121 may be about 0.02 mm. In addition, the first radiator 111 and the second radiator 121 are disposed on the frame 101 outside the middle frame substrate 101, and the first radiator 111 and the second radiator 121 are far away from an electronic device inside the electronic device, so that the radio frequency antenna 11 and the millimeter wave antenna 12 can realize a large clear area in a small space, and have good radiation performance, and the electronic device is favorable for light and thin design.
Moreover, the two adjacent radio frequency antennas 11, the two adjacent millimeter wave antennas 12, and the radio frequency antennas 11 and the millimeter wave antennas 12 are separated by a certain distance, so that the plastic middle frame 10 is prevented from being provided with a fracture to separate the adjacent antennas, the processing cost of the plastic middle frame 10 is reduced, and the structural strength of the plastic middle frame 10 is improved.
In the embodiment of the present application, the outer side of the middle frame base 101 may be specifically an outer side in terms of the internal space of the electronic device. Specifically, under the condition that the plastic middle frame 10 is wrapped around the electronic device, one side close to the inside of the electronic device is the inner side of the middle frame base 101, and one side close to the outside of the electronic device is the outer side of the middle frame base 101. Because the frame 102 is disposed outside the middle frame base 101, and the first radiator 111 and the second radiator 121 are disposed on the frame 101, the first radiator 111 and the second radiator 121 are far away from an electronic device inside the electronic device, and the radio frequency antenna 11 and the millimeter wave antenna 12 can achieve a large clearance area in a small space, thereby achieving good antenna performance.
In practical applications, the rf antenna 11 may be used to implement radiation and reception of rf antenna signals, and the rf antenna 11 generally operates in a frequency band below 6 GHz. Millimeter-wave antenna 12 may be used to facilitate the radiation and reception of millimeter-wave antenna signals, with millimeter-wave antenna 12 typically operating in the millimeter-wave frequency band. In the embodiment of the application, because the radio frequency antenna 11 and the millimeter wave antenna 12 are simultaneously arranged in the electronic device, the broadband radiation of antenna signals can be realized, and the communication quality of the electronic device is improved.
In particular, the first radiator 111 may be used to radiate or receive radio frequency signals. The first feeder 112 may be configured to feed an electrical signal of a radio frequency module inside the electronic device to the first radiator 111, and feed a radio frequency signal received by the first radiator 111 to the radio frequency module inside the electronic device. The ground body 113 may be a contact, a pin, an electrical connection pad, or other electrical connection structure, and the ground body 113 may be used to realize connection between the first radiator 111 and a reference ground.
Likewise, the second radiator 121 may be used to radiate or receive a millimeter wave signal. The second feeder 122 may be configured to feed millimeter-wave signals inside the electronic device to the second radiator 121, and feed millimeter-wave signals received by the second radiator 121 inside the electronic device.
It should be noted that, in fig. 2, only the case that the millimeter wave antenna 12 includes 4 second radiators 121 is shown, but in practical applications, the number of the second radiators 121 in the millimeter wave antenna 12 may also be other values, for example, 6, 8, or 12, and the application does not specifically limit the number of the second radiators 121 in the millimeter wave antenna 12.
In an optional embodiment of the present application, the array direction of the plurality of second radiators 121 may be consistent with the length direction of the first radiator 111, so as to further reduce the layout space of the plurality of second radiators 121, which is beneficial to the light and thin design of the plastic middle frame 10.
In some optional embodiments of the present application, the plastic middle frame 10 may be made of LDS (Laser Direct Structuring), and the rf antenna 11 and the millimeter wave antenna 12 may both be LDS antennas.
In particular, the plastic bezel 11 may be made of LDS plastic. The LDS plastic is a production technology of professional laser processing, ejection and electroplating processes, common plastic elements can be endowed with an electrical interconnection function by adding certain raw materials containing special components into the plastic, a circuit board can be directly printed on the LDS plastic in a three-dimensional mode by utilizing a laser technology, the traditional circuit board is not needed, the circuit design is more flexible, and most importantly, the volume of a product can be obviously reduced.
In the embodiment of the present application, a plurality of rf antennas 11 and a plurality of mm-wave antennas 12 may be directly manufactured on the plastic middle frame 10 by an LDS technique, and the plurality of rf antennas 11 and the plurality of mm-wave antennas 12 are all set as LDS antennas. Thus, the thicknesses of the rf antenna 11 and the millimeter-wave antenna 12 can be designed to be thin, and the clearance area of the rf antenna 11 and the millimeter-wave antenna 12 can be increased. Moreover, the radio frequency antenna 11 and the millimeter wave antenna 12 can be flexibly arranged at any position of the plastic middle frame 10, which is beneficial to the flexible arrangement of the radio frequency antenna 11 and the millimeter wave antenna 12. Moreover, a fracture can be avoided from being formed on the plastic middle frame 10 to separate the two adjacent radio frequency antennas 11, the two adjacent millimeter wave antennas 12, the radio frequency antenna 11 and the millimeter wave antenna 12, so that the processing cost of the plastic middle frame 10 is reduced, and the structural strength of the plastic middle frame 10 is improved.
In other optional embodiments of the present application, a groove is provided on a surface of the plastic bezel 10, and the rf antenna 11 and the millimeter wave antenna 12 are embedded in the groove.
Specifically, a groove may be formed in a region where an antenna needs to be disposed on the plastic middle frame 10 by a mold forming or removing process, and then the thin-sheet rf antenna 11 and the millimeter wave antenna 12 are embedded in the groove. In practical applications, in order to increase the connection strength between the radio frequency antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10, the radio frequency antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10 may be in interference fit, or an adhesive layer may be disposed between the radio frequency antenna 11, the millimeter wave antenna 12 and the groove. The embodiment of the present application does not limit this.
It should be noted that, when the radio frequency antenna 11 and the millimeter wave antenna 12 are embedded in the grooves of the plastic middle frame 10 in an embedded manner, in order to increase the clearance area of the radio frequency antenna 11 and the millimeter wave antenna 12, the radio frequency antenna 11 and the millimeter wave antenna 12 may be sheet-shaped antennas, and in order to reduce the processing cost of the electronic device, the plastic middle frame 10 may be made of at least one of polycarbonate plastic, glass fiber polycarbonate plastic, and glass fiber polyamide plastic.
In the embodiment of the present application, a surface of the frame 102 close to the middle frame base 101 is a first surface 1021, and the first radiator 111 may be disposed on the first surface 1021; the second radiator 121 may be disposed in the frame 102 and parallel to the first radiator 111.
Referring to fig. 6, a schematic diagram of a structure of a radio frequency antenna and a millimeter wave antenna of the present application is shown, and referring to fig. 7, a partially enlarged view of the structure shown in fig. 6 is shown. As shown in fig. 6 and 7, since the first radiator 111 is disposed on the first surface 1021, the first radiator 111 can be grounded through the ground body 113, and the second radiator 121 is disposed in the frame 101 and parallel to the first radiator 111, the first radiator 111 can be used as a reflective ground for the second radiator 121. Therefore, the operation of additionally grounding the second radiator 121 can be avoided, the structure of the millimeter wave antenna 12 is simplified, and the plastic middle frame 10 is more beneficial to the light and thin design.
In some optional embodiments of the present application, the frame 102 is provided with slots 1022 distributed in an array, and the second radiator 121 is disposed on a groove wall of the slot 1022; the frame 102 is further provided with a through hole penetrating the first surface 1021 and the slot 1022, through which the second feed 122 can pass and be connected to the second radiator 121.
In practical applications, the slot 1022 may be formed in an area of the plastic middle frame 10 where the second radiator 121 needs to be disposed by a mold forming or removing process, and at least two groove walls of the slot 1022 are parallel to the first surface 1021, and a through hole is disposed between the slot 1022 and the first surface 1021. Then, the second radiator 121 is formed on the groove wall of the slot 1022 by the LDS process. Finally, the second feeding body 122 is inserted into the through hole and connected to the second radiator 121
Specifically, since the second feed body 122 is embedded in the through hole penetrating the slot 1022 and the first surface 1021, one end of the second feed body 122 is close to the inside of the electronic device, and the other end of the second feed body is electrically connected to the second radiator 121, so that the millimeter wave signal inside the electronic device can be conveniently fed into the second radiator 121, and the millimeter wave signal received by the second radiator 121 is fed into the inside of the electronic device.
Optionally, the second feeder 122 may be a conductive metal pillar, and the conductive metal pillar is insulated from the first radiator 111 to realize the partition between the first radiator 111 and the second radiator 121, so that the radio frequency antenna 11 and the millimeter wave antenna 12 may operate independently, and mutual interference between the radio frequency antenna 11 and the millimeter wave antenna 12 is avoided.
In practical applications, the connection between the conductive metal pillar and the first radiator 111 may be cut off, so as to insulate the conductive metal pillar from the first radiator 111. For example, the insulation between the conductive metal pillar and the first radiator 111 may be achieved by providing an insulating layer on a surface of the conductive metal pillar contacting the first radiator 111, or by interposing an insulating foam, an insulating rubber pad, or the like between the conductive metal pillar and the first radiator 111. The embodiment of the present application does not limit this.
In other optional embodiments of the present application, the number of the second feed 122 is multiple, and each second feed 122 is connected to a non-central region of the second radiator 121, so as to implement multi-polarization radiation of the millimeter antenna.
In practical applications, in the case that the second feeding body 122 is connected to the non-central region of the second radiator 121, polarized radiation in a certain direction can be realized, and the polarized directions are different when the second feeding body is connected to different positions of the non-central region of the second radiator 121.
In the embodiment of the present application, the plurality of second feeding bodies 122 are connected to different positions of the non-central area of the second radiating body 121, so that polarized radiation in multiple directions can be realized, and the radiation performance of the millimeter wave antenna 12 is improved.
As shown in fig. 7, in the case that the second radiator 121 is rectangular, the number of the second feed bodies 122 may be 2, wherein one second feed body 122 is connected at a position close to the long edge of the second radiator 121, and the other second feed body 122 is connected at a position close to the short edge of the second radiator 121, so as to realize polarization in two different directions, and realize dual-polarization radiation of the millimeter wave antenna 12.
It should be noted that fig. 2 to 7 only show that the shape of the second radiator 121 is rectangular, and the number of the second feed bodies 122 is 2, but in practical applications, the shape of the second radiator 121 may also be circular, triangular or other special shapes, and the number of the second feed bodies 122 may also be 3, 4 or 6, and the like.
In other alternative embodiments of the present application, the slot 1022 may include opposing first and second slot walls 1023, 1024, both of the first and second slot walls 1023, 1024 being parallel to the first surface 1021, the first slot wall 1023 being proximate to the first surface 1021; the second radiator 121 is disposed on the second groove wall 1024, so that the second radiator 121 may be disposed as far as possible from the first surface 1021, and thus, a distance between the second radiator 121 and an electronic device inside the electronic device may be increased, a clearance area of the millimeter wave antenna 12 may be increased, and further, radiation performance of the millimeter wave antenna 12 may be improved.
In some optional embodiments of the present invention, the millimeter-wave antenna 12 may further include a plurality of third radiators 123, where one third radiator 123 corresponds to one second radiator 121; the third radiator 123 is disposed on the first slot wall 1023 and coupled to the second radiator 121.
In practical applications, the third radiator 123 and the second radiator 121 may be spaced apart from each other to maintain a reasonable coupling gap.
