At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.
[0025] The antenna structure provided in the embodiment of the present application can be applied to electronic devices. The electronic devices can be handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., mobile phones), mobile stations (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as electronic devices.
[0026] In one embodiment, Figure 1 As shown, an antenna structure is provided, including a radiator 100, wherein the two ends of the radiator 100 are respectively a first free end A and a second free end B, the radiator 100 has a plurality of spaced-apart feeding points K1 and a plurality of spaced-apart grounding points D1, the feeding points K1 are spaced from the grounding points D1, each feeding point K1 is used to receive a feeding signal input by the feed source S1 when being conductively connected to the feed source S1, and each grounding point D1 can be conductively connected to the floor G1.
[0027] Among them, the radiator 100 can move relative to the feed source S1 and the floor G1, so that the feed source S1 can be switchably connected to the target feeding point, the floor G1 can be switchably connected to the target grounding point, the target feeding point is one of multiple feeding points K1, and the target grounding point is one of multiple grounding points D1.
[0028] Optionally, the radiator 100 can be used as an independently arranged antenna body in the electronic device, including a flexible printed circuit (FPC) antenna radiator, a laser direct structuring (LDS) antenna radiator, a print direct structuring (PDS) antenna radiator, and a metal radiating branch. The radiator 100 can also be a metal structural part of the electronic device itself, such as a metal decorative part (Deco) on the electronic device housing as the radiator 100 of the antenna structure. The present application preferably uses the metal decorative part Deco as the radiator 100, and uses a multiplexing method to make the metal decorative part Deco have the performance of an antenna. Not only does it not need to occupy additional design space of the entire machine, but it can also effectively increase the clearance area of the antenna and meet the miniaturization design requirements of the electronic device.
[0029] The radiator 100 has a first free end A and a second free end B spaced apart from each other, so that the radiator 100 forms a non-enclosed structure, and its shape can be circular, elliptical, square, long strip or other irregular shapes, for example Figure 1 The figure shows the case where the radiator 100 is circular in shape, and the first free end A and the second free end B are opposite and spaced apart, that is, a gap is formed between the first free end A and the second free end B, so that the radiator 100 forms a ring structure with a slit. Alternatively, when the radiator is in the shape of an elongated strip, the first free end and the second free end are disposed opposite to each other, so that the radiator forms a structure extending along a straight line or an irregular curve.
[0030] Furthermore, this embodiment uses Figure 1The radiator 100 shown is an open-slit annular frame structure as an example for explanation. The radiator 100 is provided with a plurality of feeding points K1 and a grounding point G1 between a first free end A and a second free end B. Figure 1 The radiator 100 is shown with four feeding points K1 and one grounding point D1, and each feeding point K1 is correspondingly arranged at position 1 to position 4. The feed source S1 may be a device on a circuit board of an electronic device that can generate a feeding signal, and the floor G1 may be a grounding portion on a circuit board of an electronic device, so the radiator 100 can radiate and receive radio waves when the feeding point K1 is electrically connected to the feed source S1 and the grounding point D1 is electrically connected to the floor G1.
[0031] Among them, the grounding point D1 can be regarded as dividing the radiator 100 into a first radiating conductor and a second radiating conductor, that is, part of the radiator between the grounding point D1 and the first free end A is the first radiating conductor, and part of the radiator between the grounding point D1 and the second free end B is the second radiating conductor. Each feeding point K1 can be set on the first radiating conductor or the second radiating conductor. For example, when the feed source S1 is connected to a feeding point of the second radiating conductor, the second radiating conductor can be regarded as the main antenna, and the first radiating conductor can be regarded as a parasitic antenna. The feeding point K1 receives the feeding signal so that the second radiating conductor couples with the first radiating conductor through the gap to radiate electromagnetic waves.
[0032] Furthermore, in this embodiment, the radiator 100 is moved relative to the feed source S1 and the floor G1, for example, the radiator 100 rotates clockwise or counterclockwise, so that the position of the feed point K1 connected to the feed source S1 changes, and the position of the grounding point D1 connected to the floor G1 also changes, thereby changing the length of the power path from the feed point K1 to the slot and the length of the power path from the grounding point D1 to the slot, so that the electrical length of the radiator 100 changes to control the antenna structure to support the communication frequency band required for the current operation. For example, please refer to Figure 1 and Figure 2When the antenna structure needs to work in the first target frequency band, and the first target frequency band corresponds to the feed point K1 at position 2 on the radiator, the radiator 100 can be rotated clockwise to make the radiator 100 move relative to the feed source S1 and the floor G1, so that the position where the feed source S1 is connected to the radiator 100 changes from position 1 to position 2, that is, the rotation of the radiator 100 causes the feed source S1 to switch and connect to the target feeding point at position 2, or it can be said that the position of the feed point K1 formed by the feed source S1 connected to the radiator 100 has changed. At the same time, with the rotation of the radiator 100, the floor G1 is switched and connected to different grounding points, that is, the position of the grounding point D1 formed by the floor G1 connecting to the radiator 100 has also changed, and then the feed source S1 is connected to the target feeding point and the floor G1 is connected to the target grounding point, thereby adjusting the resonant frequency of the antenna structure so that the antenna structure can meet the requirements of the first target frequency band.
[0033] Similarly, please refer to Figure 3 and Figure 4 , if the antenna structure needs to work in the second target frequency band, and the second target frequency band corresponds to the feed point K1 at position 3 on the radiator, the radiator 100 can be rotated clockwise to connect the feed source S1 to the feed point K1 at position 3, and correspondingly, the position where the floor G1 is connected to the ground point D1 changes. If the antenna structure needs to work in the third target frequency band, and the third target frequency band corresponds to the feed point K1 at position 4 on the radiator, the radiator 100 can be rotated clockwise to connect the feed source S1 to the feed point K1 at position 4, and correspondingly, the position where the floor G1 is connected to the ground point D1 changes. Therefore, during the movement of the radiator 100, when the feed source S1 switches from position 1 to the feed point at position 4, the length of the conductive path between the connected feed point at position 4 and the slit becomes longer than the length of the conductive path between the feed point at position 1 and the slit, and the length of the conductive path between the ground point D1 and the slit also becomes longer, thereby achieving the change of the working frequency band of the antenna structure.
[0034] Based on this, the conduction position of the feeding point and the grounding point on the radiator is adjusted through the relative movement of the radiator, so that the electrical length of the radiator changes, and then the resonant frequency is adjusted. Therefore, without adding an additional tuner and taking up the space of the whole machine, this embodiment adopts a multiplexing method to make the metal decorative part Deco as a single antenna structure, which can not only save the manufacturing cost of the antenna, but also perform multi-band communication switching of the antenna to realize frequency reconfiguration, obtain more frequency band combinations, and improve communication performance.
[0035] The above-mentioned antenna structure includes a radiator, and the two ends of the radiator are respectively a first free end and a second free end. The radiator has a plurality of spaced-apart feeding points and a plurality of spaced-apart grounding points. The position of the feed source connected to the radiator can be adjusted by moving the radiator relative to the feed source and the floor, so that the feed source can be switchably connected to the target feeding point. At the same time, the position of the floor connected to the radiator can be adjusted, so that the floor can be switchably connected to the target grounding point, thereby changing the electrical length of the radiator. Multi-band communication switching can be performed without adding an additional tuner and without occupying the space of the entire machine, so as to achieve frequency reconfiguration and meet the working requirements of the antenna in different frequency bands.
[0036] In one embodiment, the antenna structure also includes: a first connector and a second connector, one end of the first connector is used to connect to a feed source, and the other end of the first connector can be switchably connected to a target feeding point, one end of the second connector is used to connect to the floor, and the other end of the second connector can be switchably connected to a target grounding point, and the radiator can move relative to the first connector and the second connector.
[0037] Among them, the first connector and the second connector can be elastic structures or metal contacts. The first connector is used to establish an electrical connection between the target feeding point on the radiator and the feed source, and the second connector is used to establish an electrical connection between the target grounding point on the radiator and the floor. During the movement of the radiator relative to the first connector and the second connector, the position of the feeding point connected to the other end of the first connector changes, and the position of the grounding point connected to the other end of the second connector also changes. By rotating the radiator, the contact position of the first connector and the radiator can be switched, and the contact position of the second connector and the radiator can be switched, thereby realizing the switching of different frequency bands of the antenna structure and the frequency reconfiguration of the antenna.
[0038] In one embodiment, the first connector is an elastic connector. Optionally, the first connector may be a metal spring or a spring pin. For example, if a metal spring is used as the first connector, it can be connected to the radiator by pressing the spring to improve electrical contact performance. In addition, the electrical connection using an elastic connector is also beneficial to saving the space occupied by the antenna structure in the electronic device, thereby improving space utilization.
[0039] In one embodiment, the second connecting member is an elastic connecting member. Optionally, the second connecting member may also be a metal spring or a spring pin.
[0040] In one embodiment, the first connector and the second connector are elastic connectors. Optionally, the first connector and the second connector can be configured as elastic connectors at the same time to further save the occupied space of the antenna structure and improve the electrical contact performance.
[0041] In one embodiment, the first free end and the second free end are arranged opposite to each other and a gap is formed therebetween, so that the radiator forms a ring structure, and the radiator rotates along the axis of the ring structure to move relative to the feed source and the floor.
[0042] Among them, for example Figures 1 to 4 The first free end A of the radiator 100 shown is arranged adjacent to the second free end B through a gap, so that the radiator 100 forms a slotted ring structure. Optionally, the radiator can be in a circular ring, a square ring, an elliptical ring or other irregular ring shape. Further, when the antenna structure needs to change the working frequency band, the radiator 100 can be rotated along the axis so that the feed source S1 is switched to the feed point K1 corresponding to the required frequency band, and the floor G1 is switched to the grounding point D1 corresponding to the required frequency band. That is, by rotating the radiator 100 to move relative to the feed source S1 and the floor G1, the conduction position of the feed point K1 and the grounding point D1 on the radiator 100 is adjusted to change the electrical length of the radiator 100, so that the resonant frequency changes, thereby achieving switching between different frequency bands.
[0043] In one embodiment, the first free end and the second free end are arranged opposite to each other and the radiator extends along the first direction, and the radiator can translate along the first direction to move relative to the feed source and the floor. It can be understood that the radiator forms a structure extending in a straight line or an irregular curve along the first direction, for example, the radiator is a non-enclosed structure in the shape of a long strip or a snake. For details, please refer to Figure 5 The radiator 100 shown is in the shape of a long strip. When the antenna structure needs to switch the communication frequency band, the radiator 100 is translated to the left or right along the extension direction of the radiator 100 to switch different feeding points K1 to connect to the feed source S1, and switch different grounding points D1 to connect to the floor G1, thereby meeting the working requirements of the antenna in different frequency bands.
[0044] In one embodiment, each of the feeding points is arranged between one of the first free end and the second free end and the grounding point, and a plurality of feeding points are arranged at equal intervals on the radiator. Taking the case where each feeding point is arranged between the grounding point and the second free end as an example, during the relative movement of the radiator, the length of the conducting path between the position of the feeding point connected to the feed source and the second free end changes, and the length of the conducting path between the position of the grounding point connected to the floor and the second free end also changes, thereby changing the electrical length of the radiator to adjust the resonant frequency of the antenna structure, so as to realize multi-band switching and frequency reconfiguration of the antenna.
[0045] In one embodiment, the radiator is also provided with a cavity, and the antenna structure also includes a liquid metal structure, one end of the liquid metal structure is used to connect one of the first free end and the second free end, wherein the liquid metal structure can flow telescopically in the cavity of the radiator to adjust the extension size of the radiator.
[0046] Among them, the cavity of the radiator can be a pipe with multiple cavity units isolated from each other, and a switch mechanism can be provided between two adjacent cavity units to play an isolation role. When the antenna structure needs to change the communication frequency band, for example, it needs to switch to a low frequency range, then the switch mechanisms corresponding to the low frequency range are opened in sequence at the end of the radiator close to the liquid metal, so that the corresponding number of cavity units form a passage, and then based on the fluidity of the liquid metal, the liquid metal flows into the last cavity unit opened in the cavity of the radiator, thereby increasing the electrical length of the radiator to reach the required low frequency range. Therefore, in addition to adjusting the position of the feeding point and the grounding point to change the communication frequency band through the movement of the radiator, the extension length of the radiator can also be adjusted by controlling the length of the liquid metal flowing into the cavity of the radiator, thereby realizing multi-band switching of the antenna structure, thereby adding an optimizable variable to further enrich the frequency reconfigurable implementation method of the antenna structure and further optimize the performance of the antenna frequency band switching.
[0047] Optionally, the liquid metal can be made of gallium-indium alloy, antimony, magnesium, aluminum and other materials. It has a low melting point, is in liquid form at room temperature, has the electronic properties required for antennas, and has greater elasticity than solid metals such as copper. It can receive signals well, and repeated bending will not cause material fatigue. It has self-repair capabilities and can realize reconstructive antennas.
[0048] In one embodiment, the radiator is further provided with a cavity, the cavity is filled with liquid metal, and the radiator moves with the flow of the liquid metal.
[0049] Optionally, the radiator can be made of flexible dielectric material, and liquid metal can be filled in the radiator cavity to form an antenna structure. Based on the fluidity of the liquid metal, when the operating frequency band of the antenna needs to be changed, pressure can be applied to the radiator. The liquid metal can freely change its liquid shape under the action of pressure. The change in liquid shape helps the radiator to rotate or translate, thereby helping the radiator to switch the feeding point and the grounding point during the rotation or translation process. The electrical length of the radiator can be changed according to the frequency band requirements to achieve frequency band switching.
[0050] In one embodiment, when different feeding points are conductively connected to the feed source, the antenna structure operates in different frequency bands, and the different frequency bands include at least two of B28 / N28, B20 / N20, B5 / N5, B8 / N8, B1 / N1, B3 / N3, B39 / N39, B40 / N40, and B41 / N41.
[0051] Among them, the feeding points at different positions are switched to be connected with the feed source through the movement of the radiator, and the grounding points at different positions are switched to be connected with the floor, so as to realize multi-band switching of the antenna structure to achieve the frequency reconfiguration of the antenna and the combination of more frequency bands.
[0052] Optionally, the multi-band switching of the antenna may include switching in a low frequency range, a medium frequency range, a high frequency range and an ultra-high frequency range. Exemplarily, the medium frequency range may include 4G medium frequency signals (e.g., B1, B3, B39, etc.), 5G medium frequency signals (e.g., N1, N3, N39, etc.); the high frequency band range signals may include 4G high frequency signals (e.g., B40, B41, B7, etc.), 5G high frequency signals (e.g., N40, N41, N7, etc.) and WiFi 2.4G signals; the ultra-high frequency band range signals may include 5G ultra-high frequency signals (e.g., N77, N78, N79, etc.).
[0053] In one embodiment, the antenna structure further includes: a driving module, the driving module being configured to drive the radiator to move relative to the feed source and the floor according to a received driving instruction.
[0054] Among them, the driving module may include a rotating structure, a translation bracket and other structures for controlling movement. That is, when the antenna operates in a required target frequency band, the relevant communication control chip module can send a driving instruction to the driving module to instruct the driving module to drive the radiator to rotate or translate, so that the radiator moves to the target position, that is, to make the feed source switch connection connected to the target feeding point, and the floor switch connection connected to the target grounding point, so that the radiator reaches the target electrical length to achieve switching to the target frequency band.
[0055] In one embodiment, a control method for an antenna structure is provided, including step S102, which can adjust the conductive positions of the feeding point and the grounding point on the radiator through the relative movement of the radiator, so as to switch different feeding points to be conductively connected to the feed source, and switch different grounding points to be conductively connected to the floor. Without adding an additional tuner and without occupying the space of the entire machine, a single antenna structure can be used to switch multi-band communications, so as to achieve frequency reconfiguration, obtain more frequency band combinations, and improve communication performance.
[0056] Step S102: Based on the target frequency band, the radiator is controlled to move relative to the feed source and the floor, so that the feed source can be switched to be connected to the target feeding point of the radiator, and the floor can be switched to be connected to the target grounding point of the radiator. The two ends of the radiator are respectively the first free end and the second free end, the radiator has a plurality of spaced feeding points and a plurality of spaced grounding points, and the feeding points are spaced from the grounding points; the target feeding point is one of the plurality of feeding points, and the target grounding point is one of the plurality of grounding points; when different feeding points are connected to the feed source, the antenna structure works in different frequency bands.
[0057] The relevant description of step S102 can refer to the relevant description in the above embodiment, which will not be repeated here.
[0058] In one embodiment, the radiator is connected to a driving module, and step S102 further includes the following steps: outputting a driving instruction based on a target frequency band, so that the driving module drives the radiator to move relative to a feed source and a floor according to the received driving instruction.
[0059] For the relevant description of the above steps, reference can be made to the relevant description in the above embodiments, which will not be repeated here.
[0060] In one embodiment, a control device for an antenna structure is provided, and the control device is used to control the movement of the radiator relative to the feed source and the floor based on the target frequency band, so that the feed source can be switchably connected to the target feeding point of the radiator, and the floor can be switchably connected to the target grounding point of the radiator.

In this way, the switching of different frequency bands of the antenna structure and the frequency reconfiguration of the antenna are achieved, meeting the working requirements of the antenna in different frequency bands.
