[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The antenna provided in the embodiments of the present application can be applicable to various electronic devices with communication functions, which may include but are not limited to personal computers (e.g., laptops, notebook computers, etc.), mobile computing devices (e.g., tablets, tablet computers, e-reader devices, etc.), mobile communication devices (e.g., smart phones, cellular phones, personal digital assistants, messaging devices, handheld computers, etc.), connection and charging devices (e.g., hubs, docking stations, adapters, chargers, etc.), audio / video / data recording and / or playback devices (e.g., cameras, recorders, handheld scanners, monitors, etc.) and other similar electronic devices that can use USB connectors (interfaces) for communication, battery charging and / or power delivery.

[0028] Figure 1 This is a schematic diagram of the structure of an antenna provided in an embodiment of the present application. Figure 1 As shown, the antenna may include a first radiator 101 and a second radiator 102, the first radiator 101 and the second radiator 102 are coupled to each other, the first radiator 101 includes a first feeding point, a second feeding point and a grounding point, and the second radiator 102 includes a third feeding point, wherein:

[0029] The first radiator 101 is used to transmit or receive a first radio frequency signal corresponding to a first preset frequency band under the action of a first feeding point and a grounding point, or to transmit or receive a second radio frequency signal corresponding to a second preset frequency band under the action of a second feeding point and a grounding point;

[0030] The second radiator 102 and the first radiator 101 are used to transmit or receive a third radio frequency signal corresponding to a third preset frequency band under the action of a third feeding point and a grounding point.

[0031] During implementation, when the electrical signal sent by the electronic device is transmitted between the first feeding point and the grounding point, the first radiator 101 will radiate a first radio frequency signal; when the electrical signal sent by the electronic device is transmitted between the first feeding point and the grounding point, the first radiator 101 will radiate a second radio frequency signal; when the electrical signal sent by the electronic device is transmitted between the third feeding point and the grounding point, resonance is formed between the first radiator 101 and the second radiator 102 to radiate a third radio frequency signal, thereby achieving the output of multiple radio frequency signals.

[0032] In some embodiments, since the first radiator 101 and the second radiator 102 both act as coupling capacitors, the first preset frequency band and the second preset frequency band can be controlled by adjusting the length and width of the first radiator 101, that is, the first preset frequency band and the second preset frequency band are both related to the length and width of the first radiator 101. For example, the greater the length of the first radiator 101, the greater the capacitance value corresponding to the first radiator 101, and the lower the first preset frequency band and the second preset frequency band; the greater the width of the first radiator 101, the smaller the capacitance value corresponding to the first radiator 101, and the higher the first preset frequency band and the second preset frequency band.

[0033] Optionally, the first radiator 101 and the second radiator 102 may be formed in a variety of ways. For example, the first radiator 101 and the second radiator 102 may be formed by a metal frame of an electronic device, may be formed by an FPC (Flexible Printed Circuit), or may be formed by an LDS (Laser Direct Structuring) process. It should be noted that the first radiator 101 and the second radiator 102 may be formed in the same way or in different ways.

[0034] Optionally, the first preset frequency band and the second preset frequency band may be different or the same, and may be specifically determined by the type of the first radiator 101 or the distances between the first feeding point, the second feeding point and the grounding point.

[0035] Exemplarily, if the distance between the first feeding point and the grounding point is different from the distance between the second feeding point and the grounding point, the first radiator 101 between the first feeding point and the grounding point can radiate a first RF signal corresponding to the first preset frequency band, and the first radiator 101 between the second feeding point and the grounding point can radiate a second RF signal corresponding to the second preset frequency band, resulting in the first preset frequency band being different from the second preset frequency band.

[0036] Optionally, the positional relationship between the first feeding point, the second feeding point and the grounding point is set by technical personnel in this field according to actual conditions. The first feeding point may be located between the second feeding point and the grounding point, the grounding point may be located between the first feeding point and the second feeding point, or the second feeding point may be located between the first feeding point and the grounding point. This application does not impose any restrictions.

[0037] Optionally, the antenna may include any of an IFA antenna, a LOOP antenna, a monopole antenna, and a slotted antenna to output a first RF signal, a second RF signal, and a third RF signal. For example, the first feeding point, the grounding point, and the first radiator 1011 may form a ring LOOP antenna, or the second feeding point, the grounding point, and the second radiator 1012 may form an inverted F antenna, which may be configured by a person skilled in the art according to actual conditions and is not limited in this application.

[0038] Optionally, the grounding point may include a first grounding structure and a second grounding structure, and the second grounding structure is connected to the first grounding structure. Both the first grounding structure and the second grounding structure may be formed by a conductor structure. For example, in some embodiments, the first grounding structure may be formed by a metal middle frame of an electronic device, and the second grounding structure may be formed by a printed circuit board (PCB) of the electronic device. It is understandable that in some other embodiments, the first grounding structure may also be formed by a circuit board of an electronic device, and the second grounding structure may also be formed by a metal middle frame of an electronic device.

[0039] The first grounding structure is electrically connected to the first radiator 101 , and the second grounding structure is electrically connected to the second radiator 102 .

[0040] In the above antenna, a coupling arrangement is set between the first radiator 101 and the second radiator 102, so that under the action of the first feeding point and the grounding point, the first radiator 101 can transmit or receive a first RF signal corresponding to the first preset frequency band, or, under the action of the second feeding point and the grounding point, the first radiator 101 can transmit or receive a second RF signal corresponding to the second preset frequency band, and under the action of the third feeding point and the grounding point, the second radiator 102 and the first radiator 101 can transmit or receive a third RF signal corresponding to the third preset frequency band, thereby realizing the reception and transmission of multiple RF signals through a single antenna structure, improving the compatibility of the antenna structure with the reception and transmission of RF signals, and reducing the structural requirements of the antenna structure on the clearance area of ​​the electronic device.

[0041] In some embodiments, such as Figure 2 As shown, the first radiator 101 includes a first radiator 1011 and a second radiator 1012. The first radiator 1011 is used to transmit or receive a first RF signal corresponding to a first preset frequency band, and the second radiator 1012 is used to transmit or receive a second RF signal corresponding to a second preset frequency band.

[0042] During the implementation process, the first feeding point is located on the first partial radiator 1011, and the second feeding point is located on the second partial radiator 1012. When the electronic device needs to send or receive a first radio frequency signal, an electrical signal is transmitted through the first feeding point so that the electronic device sends or receives the first radio frequency signal through the first partial radiator 1011; when the electronic device needs to send or receive a second radio frequency signal, an electrical signal is transmitted through the second feeding point so that the electronic device sends or receives the second radio frequency signal through the second partial radiator 1012.

[0043] The first feeding point may be located on the first radiator 1011 or on the second radiator 1012, and may be specifically set by those skilled in the art according to actual conditions, and this application does not limit this. Figure 2 The positional relationship is only an example and should not be regarded as a limitation to the present application.

[0044] Optionally, the coupling structure formed between the first partial radiator 1011 and the second partial radiator 1012 may be formed, or a partial area of ​​the first partial radiator 1011 and a partial area of ​​the second partial radiator 1012. The specific setting is made by technicians in this field according to actual conditions and is not limited in this application.

[0045] For example, Figure 2 As shown, taking the coupling structure formed between the first part radiator 1011 and the second radiator 102 as an example, the electronic device transmits an electrical signal through the third feeding point, and transmits the electrical signal to the grounding point through the coupling structure between the first part radiator 1011 and the second radiator 102, thereby realizing the transmission of the third radio frequency signal.

[0046] It can be understood that by providing the first partial radiator 1011 and the second partial radiator 1012 , the first radiator 101 can distinguish the receiving and sending processes of the first RF signal and the second RF signal, thereby realizing independent receiving and sending of the first RF signal and the second RF signal.

[0047] In some embodiments, since the first radiator 101 and the second radiator 102 both act as coupling capacitors, the third preset frequency band can be controlled by adjusting the target coupling distance between the first radiator 101 and the second radiator 102, that is, the third preset frequency band is related to the target coupling distance. For example, the smaller the target coupling distance between the first radiator 101 and the second radiator 102, the greater the capacitance value corresponding to the coupling structure of the first radiator 101 and the second radiator 102, and the higher the third preset frequency band.

[0048] In some embodiments, the specific values ​​of the first preset frequency band, the second preset frequency band and the third preset frequency band can be obtained by those skilled in the art after setting the specific structural parameters of the first radiator 101 and the second radiator 102 according to actual conditions. The present application does not impose any restrictions. For example, the above-mentioned first preset frequency band and the third preset frequency band can both be greater than the second preset frequency band, and the first preset frequency band and the third preset frequency band can be the same or different.

[0049] Figure 3 This is a diagram of an implementation structure of an antenna provided in an embodiment of the present application. Figure 3 As shown, taking the first radiator 101 as a LOOP antenna and an IFA antenna, and the second radiator 102 as a monopole antenna as an example, the LOOP antenna and the IFA antenna share a common ground, the length of the first radiator 101 is 13.5 mm, the width of the first radiator 101 is 8.5 mm, the coupling distance between the first radiator 101 and the second radiator 102 is 0.8 mm, the width of the second radiator 102 is 3.5 mm, and the length of the second radiator 102 is 8.5 mm. Under the above structural parameters, the first preset frequency band corresponding to the LOOP antenna is the N78 band, the second preset frequency band corresponding to the IFA antenna is the N41 band, and the third preset frequency band corresponding to the monopole antenna is the N78 band. Antenna performance requirements.

[0051] In some embodiments, such as Figure 5 As shown, the electronic device may further include a clearance area, in which the first radiator 101 and the second radiator 102 are both disposed, and a height of the clearance area is less than or equal to 1.5 mm.

[0052] Among them, the number of the above-mentioned clearance areas can be one or more, and they can be located in any one or more sides of the electronic device respectively. For example, when the clearance areas including the above-mentioned antennas are respectively provided on the two sides of the electronic device, the above-mentioned first radiator 101 and the second radiator 102 can be respectively provided on the two sides, that is, the above-mentioned first radiator 101 and the second radiator 102 are provided on side A, and the above-mentioned first radiator 101 and the second radiator 102 are also provided on side B.

[0053] Among them, the arrangement of the above-mentioned first radiator 101 and the second radiator 102 in the clearance area is determined by the size of the clearance area, so as to accommodate the above-mentioned first radiator 101 and the second radiator 102 in the clearance area. The specific arrangement is performed by technical personnel in this field according to actual conditions, and this application does not impose any restrictions.
