Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] Mobile communication technology refers to the technology of transmitting information through wireless network connection. It mainly includes mobile communication, satellite communication and mobile Internet technology. Mobile communication technology is the most common mobile communication technology. It uses base station network for signal transmission and can realize functions such as voice calls, text message sending and data transmission.

[0003] In general, mobile communication technology has become an indispensable part of modern society, bringing great convenience to people's lives and work. With the advancement of communication technology, various communication terminals have brought more and more changes to people's lives. However, there are more and more problems in various application scenarios, which require technicians to solve one by one.

[0004] In mobile communications, Specific Absorption Ratio (SAR) refers to a unit of measurement for the absorption of radio frequency energy by the human body. When wireless devices such as mobile phones emit electromagnetic radiation, part of the energy will be absorbed by the human body, and the SAR value is used to measure the amount of this absorption. The SAR value is usually expressed in units of watts per kilogram (W / kg), which is the amount of electromagnetic radiation energy absorbed by mobile phones and other devices per kilogram of human tissue under specific power conditions. Therefore, the higher the SAR value, the greater the radiation energy absorbed by a unit mass of human tissue.

[0005] When designing antennas for mobile communication devices, it is necessary to consider how to reduce the absorption of radiated energy by the human body. The design of the antenna needs to comply with relevant SAR regulations to ensure that the radiation level of the device is within the safe range under typical usage conditions.

[0006] In the related art, it is often difficult to achieve both low SAR values ​​and high performance antennas because there is a certain trade-off between them. Generally speaking, designing an antenna with a low SAR value may limit its transmission power, thereby reducing its performance. Designing an antenna with high performance may increase the radiation energy, thereby increasing the SAR value. It can be seen that in the related art, there is a problem that it is difficult to achieve both low SAR values ​​and high performance of the antenna. Summary of the invention

[0007] The present application provides a frame and an electronic device, which are conducive to achieving a high antenna performance while having a low SAR value.

[0008] In a first aspect, the present application provides an electronic device, including a first antenna and a second antenna, wherein an operating frequency band of the first antenna is different from an operating frequency band of the second antenna, the first antenna includes a first feeding unit and a first antenna radiator, the first feeding unit and the first antenna radiator are electrically connected, the second antenna includes a second feeding unit and a second antenna radiator, the second feeding unit and the second antenna radiator are electrically connected;

[0009] The plane where the first antenna radiator is located is arranged at an angle with the plane where the second antenna radiator is located, and there is a coupling gap between the first antenna radiator and the second antenna radiator, and the first antenna radiator is coupled to the second antenna radiator through the coupling gap.

[0010] In the embodiment of the present application, since the first antenna radiator is coupled to the second antenna radiator through a coupling gap, and the plane where the first antenna radiator is located is set at an angle to the plane where the second antenna radiator is located, in the first antenna and the second antenna, when the antenna with a higher working frequency band is excited, a certain unidirectional current can be coupled in the antenna radiator of the antenna with a lower working frequency band, so that the current generated during the operation of the antenna with a higher working frequency band can be dispersed to the plane where the first antenna radiator is located and the plane where the second antenna radiator is located, that is, the current generated by the antenna with a higher working frequency band can be dispersed to two different planes, which is beneficial to reducing the SAR value of the antenna, that is, the SAR value of the antenna can be reduced without reducing the antenna performance, and since a certain unidirectional current can be coupled in the antenna radiator of the antenna with a lower working frequency band, it is beneficial to improve the performance of the antenna, and thus it is beneficial to achieve that the antenna has a low SAR value and a high antenna performance.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] In the following, in conjunction with the accompanying drawings, an electronic device provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0032] See also Figures 1 to 4 , an embodiment of the present application provides an electronic device, including a first antenna 100 and a second antenna 200, wherein the working frequency band of the first antenna 100 is different from the working frequency band of the second antenna 200, the first antenna 100 includes a first feeding unit 120 and a first antenna radiator 110, the first feeding unit 120 and the first antenna radiator 110 are electrically connected, the second antenna 200 includes a second feeding unit 240 and a second antenna radiator 210, the second feeding unit 240 and the second antenna radiator 210 are electrically connected;

[0033] The plane where the first antenna radiator 110 is located is set at an angle to the plane where the second antenna radiator 210 is located, and there is a coupling gap between the first antenna radiator 110 and the second antenna radiator 210, and the first antenna radiator 110 is coupled to the second antenna radiator 210 through the coupling gap.

[0034] The electronic device may be a mobile terminal such as a mobile phone, a tablet computer, a notebook, a smart watch, etc. In addition, the electronic device may also be a device with an antenna in a base station. The first antenna 100 and the second antenna 200 may be any two antennas with different working frequency bands in the electronic device. For example, the first antenna 100 may be an antenna with a working frequency band of N78, and the second antenna 200 may be a middle / high frequency (MHB) antenna. For another example, the first antenna 100 may be a middle / high frequency antenna, and the second antenna 200 may be a low frequency antenna. Among them, the N78 frequency band is 3300MHz-3800MHz; the middle / high frequency band is 1710MHz-2690MHz; and the low frequency band is 700MHz-960MHz. The following takes the working frequency band of the first antenna 100 as the N78 frequency band and the working frequency band of the second antenna 200 as MHB as an example to further explain the electronic device provided in the embodiment of the present application.

[0035] Specifically, the first antenna 100 and the second antenna 200 may be antennas inside the electronic device or antennas made on the surface of the electronic device, or one may be an antenna inside the electronic device and the other may be an antenna made on the surface of the electronic device.

[0036] It can be understood that the electronic device further includes a circuit board, and the first feeding unit 120 and the second feeding unit 240 are two different feeding units in the circuit board, wherein the feeding units are also referred to as feed sources.

[0037] Since the plane where the first antenna radiator 110 is located is set at an angle to the plane where the second antenna radiator 210 is located, the first antenna radiator 110 and the second antenna radiator 210 can be located in different planes, wherein the angle between the plane where the first antenna radiator 110 is located and the plane where the second antenna radiator 210 is located can be located near 90°. For example, in some embodiments of the present application, the plane where the first antenna radiator 110 is located is perpendicular to the plane where the second antenna radiator 210 is located.

[0038] It should be noted that, as the operating frequency band of the antenna is higher, the size of the antenna radiator is correspondingly smaller. For example, in some embodiments of the present application, when the operating frequency band of the first antenna 100 is the first operating frequency band, the operating frequency band of the second antenna 200 is the second operating frequency band, and the minimum frequency value of the first operating frequency band is greater than the maximum frequency value of the second operating frequency band, the size of the first antenna radiator 110 will be smaller than the size of the second antenna radiator 210. In this case, please refer to Figure 5 , Figure 5The direction indicated by the arrow in is the direction of current flow. When the first antenna 100 is excited, the same-direction current can be excited in the second antenna radiator 210. Although the second antenna 200 excites a higher-order mode through the coupling of the first antenna 100 and there is a reverse current, the radiation aperture of the first antenna 100 is still increased, and the performance of the first antenna 100 is ultimately improved, so that the first antenna 100 has both a low SAR value and high performance.

[0039] In other embodiments of the present application, when the operating frequency band of the first antenna 100 is the first operating frequency band, the operating frequency band of the second antenna 200 is the second operating frequency band, and the maximum frequency value of the first operating frequency band is less than the minimum frequency value of the first operating frequency band, the size of the first antenna radiator 110 will be larger than the size of the second antenna radiator 210. In this case, when the second antenna 200 is excited, a unidirectional current can be excited in the first antenna radiator 110. Although the first antenna 100 excites a higher-order mode through the coupling of the second antenna 200 and there is a reverse current, the radiation aperture of the second antenna 200 is still increased, and the performance of the second antenna 200 is ultimately improved, so that the second antenna 200 has both a low SAR value and high performance.

[0040] It can be understood that in order to enable the first antenna radiator 110 to be coupled with the second antenna radiator 210 through the coupling gap, when the first antenna 100 and the second antenna 200 are positioned, one side of the first antenna radiator 110 can be adjacent to one side of the second antenna radiator 210, and a certain gap can be formed between the two sides as the above-mentioned coupling gap, so that the first antenna radiator 110 can be coupled with the second antenna radiator 210 through the coupling gap.

[0041] The first antenna radiator 110 and the second antenna radiator 210 may be various metal radiators.

[0042] In this embodiment, since the first antenna radiator 110 is coupled to the second antenna radiator 210 through a coupling gap, and the plane where the first antenna radiator 110 is located is set at an angle to the plane where the second antenna radiator 210 is located, in the first antenna 100 and the second antenna 200, when the antenna with a higher working frequency band is excited, a certain unidirectional current can be coupled in the antenna radiator of the antenna with a lower working frequency band, so that the current generated during the operation of the antenna with a higher working frequency band can be dispersed to the plane where the first antenna radiator 110 is located and the plane where the second antenna radiator 210 is located, that is, the current generated by the antenna with a higher working frequency band can be dispersed to two different planes, which is beneficial to reducing the SAR value of the antenna, that is, the SAR value of the antenna can be reduced without reducing the antenna performance, and since a certain unidirectional current can be coupled in the antenna radiator of the antenna with a lower working frequency band, it is beneficial to improve the performance of the antenna, and thus it is beneficial to achieve that the antenna has a low SAR value and a high antenna performance.

[0043] Optionally, see Figure 2 The electronic device includes a frame 600 and a back cover 700 , the plane where the first antenna radiator 110 is located is parallel to the back cover 700 , and the frame 600 includes the second antenna radiator 210 .

[0044] Among them, the frame 600 may refer to the middle frame of the electronic device, the back cover 700 may also be the back cover of the electronic device, the frame 600 may be a metal frame, the first antenna 100 may also be a built-in antenna of the electronic device, and the first antenna radiator 110 may be a plate-shaped radiator arranged inside the electronic device and parallel to the back cover. The first antenna radiator 110 may be arranged close to the back cover 700, specifically, between the battery and the back cover. The second antenna radiator 210 may be a radiator separated by a break in the metal frame, that is, the second antenna 200 is a metal frame antenna.

[0045] See also Figure 3 and Figure 4 In some embodiments of the present application, the first antenna 100 further includes a first conductive member 130 and a third conductive member 140, the first feeding unit 120 is electrically connected to the first antenna radiator 110 through the first conductive member 130, and the first antenna radiator 110 is grounded through the third conductive member 140, the second antenna 200 further includes a second conductive member 220 and a fourth conductive member 230, the second feeding unit 240 is electrically connected to the second antenna radiator 210 through the second conductive member 220, and the second antenna radiator 210 is grounded through the fourth conductive member 230.

[0046] The first conductive member 130 and the second conductive member 220 can be used as feeding tongues to facilitate the feeding unit to feed the corresponding antenna radiator through the corresponding feeding tongues. The third conductive member 140 and the fourth conductive member 230 are used as ground return units of the corresponding antenna. The first conductive member 130, the second conductive member 220, the third conductive member 140 and the fourth conductive member 230 can be various types of conductive sheets, for example, they can all be metal sheets. See Figure 3 and Figure 4 The electronic device may further include a floor unit 300, and the floor unit 300 may be a metal structure. The third conductive member 140 and the fourth conductive member 230 are electrically connected to the floor unit 300, respectively.

[0047] See also Figure 3 , the first feeding unit 120 can be disposed between the first conductive sheet and the floor unit 300 , and the second feeding unit 240 can be disposed between the second conductive sheet and the floor unit 300 .

[0048] In the embodiment of the present application, the first antenna radiator 110 of the first antenna 100 of the N78 frequency band is located at the back of the electronic device, and the second antenna radiator 210 of the second antenna 200 of the MHB frequency band is located at the side of the electronic device. Figure 3 and Figure 4 , the spacing between the first antenna radiator 110 and the second antenna radiator 210 in the width direction of the electronic device is Z1, and the spacing between the first antenna radiator 110 and the second antenna radiator 210 in the thickness direction of the electronic device is Z2. Thus, by designing smaller Z1 and Z2, a smaller coupling gap can be provided between the first antenna radiator 110 and the second antenna radiator 210, so that the first antenna radiator 110 and the second antenna radiator 210 are coupled through the coupling gap. In this way, when the first antenna 100 is excited, a certain current will be coupled to the second antenna radiator 210, such as Figure 3 and Figure 4 As shown. Since the first antenna radiator 110 is located at the back of the electronic device and the second antenna radiator 210 is located at the side of the electronic device, the currents of the two are dispersed on different sides of the electronic device, thereby reducing the SAR value. Although the second antenna radiator 210 is excited by the coupling of the first antenna radiator 110 to a higher-order mode and there is a reverse current, it still increases the radiation aperture of the first antenna 100, and ultimately improves the performance of the first antenna 100.

[0049] In this embodiment, since the plane where the first antenna radiator 110 is located is parallel to the back cover 700, the frame 600 includes the second antenna radiator 210. In this way, when the antenna with a higher working frequency band in the first antenna 100 and the second antenna 200 is excited, the current generated can be dispersed to the side and back of the electronic device, which is beneficial to further reduce the SAR value of the antenna.

[0050] Optionally, the electronic device further includes a coupling unit 400 , and the first antenna radiator 110 is further coupled to the second antenna radiator 210 through the coupling unit 400 .

[0051] The coupling unit 400 may include a coupling element. For example, the coupling unit 400 may include a coupling element such as a capacitor or an inductor.

[0052] In this embodiment, due to Figure 3 and Figure 4 In the illustrated embodiment, in order to ensure the coupling effect of the first antenna radiator 110 coupling with the second antenna radiator 210 through the coupling gap, it is necessary to reduce the spacing between the first antenna radiator 110 and the second antenna radiator 210 as small as possible. After reducing the spacing, the current distribution will be relatively concentrated, so that the low SAR effect cannot reach the optimal. Based on this, in the embodiment of the present application, by making the first antenna radiator 110 also coupled with the second antenna radiator 210 through the coupling unit 400, due to the presence of the coupling unit 400, it can be ensured that there is a good coupling effect between the first antenna radiator 110 and the second antenna radiator 210. Therefore, the spacing between the first antenna radiator 110 and the second antenna radiator 210 can be increased to a certain extent, which is conducive to making the current distribution more dispersed to achieve a better low SAR effect. In addition, compared with the gap coupling method, the coupling amount is better controlled by using the coupling unit 400 for coupling, and the coupling amount can be adjusted more accurately so that the back and side current distributions reach the expected proportion, so as to further reduce the SAR value.

[0053] Optionally, the first antenna 100 also includes a first conductive member 130, the first feeding unit 120 is electrically connected to the first antenna radiator 110 through the first conductive member 130, the second antenna 200 also includes a second conductive member 220, the second feeding unit 240 is electrically connected to the second antenna radiator 210 through the second conductive member 220, and the first conductive member 130 is electrically connected to the second conductive member 220 through the coupling unit 400, so that the first antenna radiator 110 is coupled to the second antenna radiator 210.

[0054] The first conductive member 130 and the second conductive member 220 may be used as feeding tongues to facilitate the feeding unit to feed power to the corresponding antenna radiator through the corresponding feeding tongues.

[0055] It should be noted that the first antenna radiator 110 described in the above embodiment is also coupled with the second antenna radiator 210 through the coupling unit 400, which means that the first antenna radiator 110 is coupled with the second antenna radiator 210 through the first conductive member 130, the coupling unit 400 and the second conductive member 220 in sequence.

[0056] Specifically, since the first antenna radiator 110 is directly connected to the first conductive member 130, the two can be used as a whole, and the second antenna radiator 210 is directly connected to the second conductive member 220, the two can be used as a whole. Based on this, the first conductive member 130 is electrically connected to the second conductive member 220 through the coupling unit 400, that is, the first conductive member 130 is coupled to the second conductive member 220 through the coupling unit 400, and the first antenna radiator 110 and the first conductive member 130 are a whole, and the second antenna radiator 210 and the second conductive member 220 are also a whole, so the first antenna radiator 110 is coupled to the second antenna radiator 210 through the coupling unit 400.

[0057] In this embodiment, since both the first conductive sheet and the second conductive sheet need to be connected to the circuit board, the distance between the first conductive sheet and the second conductive sheet is relatively close. Therefore, the coupling unit 400 can be set between the first conductive sheet and the second conductive sheet, and the first conductive member 130 can be electrically connected to the second conductive member 220 through the coupling unit 400, so that the first antenna radiator 110 can be coupled to the second antenna radiator 210 through the coupling unit 400.

[0058] Optionally, the operating frequency band of the first antenna 100 is the first operating frequency band, the operating frequency band of the second antenna 200 is the second operating frequency band, the minimum frequency value of the first operating frequency band is greater than the maximum frequency value of the second operating frequency band, and the first antenna radiator 110 is parallel to the second antenna radiator 210;

[0059] The first antenna radiator 110 includes a first feeding point 111 for electrically connecting to the first conductive member 130. The first antenna 100 also includes a third conductive member 140. The first end 112 of the first antenna radiator 110 is grounded through the third conductive member 140. The second end 113 of the first antenna radiator 110 is the antenna end of the first antenna 100. The second antenna radiator 210 includes a second feeding point 211 for electrically connecting to the second conductive member 220. The second antenna 200 also includes a fourth conductive member 230. The first end 212 of the second antenna radiator 210 is grounded through the fourth conductive member 230. The second end 213 of the second antenna radiator 210 is the antenna end of the second antenna 200. The second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located on the same side of the first conductive member 130.

[0060] See also Figure 6 , Figure 6 The embodiment shown is in Figure 3 and Figure 4 On the basis of the illustrated embodiment, a coupling unit 400 is additionally provided between the first conductive member 130 and the second conductive member 220 , and the coupling gap can be increased, that is, the values ​​of Z1 and Z2 are increased.

[0061] The above-mentioned antenna end refers to the endmost part of the antenna structure, usually refers to the physical end of the antenna radiator, and mostly refers to the floating end.

[0062] It can be understood that the first feeding unit 120 is electrically connected to the first feeding point 111 through the first conductive sheet, and the second feeding unit 240 is electrically connected to the second feeding point 211 through the second conductive sheet.

[0063] The length direction of the first antenna radiator 110 may be the same as the length direction of the second antenna radiator 210. The second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 being located on the same side of the first conductive member 130 may specifically mean that the second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located on the same side of a target plane passing through the first conductive member 130, wherein the target plane is perpendicular to the length direction of the first antenna radiator 110. The target plane passing through the first conductive member 130 specifically refers to a plane that includes at least one position point in the first conductive member 130 and is perpendicular to the length direction of the first antenna radiator 110.

[0064] Specifically, see Fig. 9 and Fig.10In some embodiments of the present application, the end of the first conductive member 130 connected to the first feeding unit 120 is point A, the position of the first feeding point 111 is point B, the second end 113 of the first antenna radiator 110 is point C, the second feeding point 211 is point D, and the second end 213 of the second antenna radiator 210 is point E. Figure 8 and Fig.10 They are Fig. 9 In the corresponding feeding coupling principle diagram, for point A, when the impedances ABC and ADE are both capacitive or inductive at point A, the currents of the BC segment and the DE segment are distributed in the same direction. Thus, the specific structure of the coupling unit 400 can be designed according to the size of the BC segment and the DE segment, so that the BC segment and the DE segment can have the same current distribution. Figure 8 The third inductor 271 and the second capacitor 172 connected in parallel form a filter resonant circuit 270 in the following embodiment. Figure 8 The third capacitor 260 and the second inductor 250 in the second antenna 200 are used as a matching circuit. Figure 8 The first capacitor 160 and the first inductor 150 are used as a matching circuit for the first antenna 100. It can be understood that the first antenna 100 also includes the first matching circuit, and the second antenna 200 also includes the second matching circuit.

[0065] In this embodiment, since the second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located on the same side of the first conductive member 130, it is only necessary to make the two antenna radiators have capacitive reactance or inductive reactance at one end of the first conductive member 130 for connecting to the first feeding unit 120, so that the two antenna radiators have the same direction of current distribution. Fig.11 As shown, Fig.11 The direction indicated by the arrow in is the flow direction of the current, thereby improving the antenna performance of the first antenna 100.

[0066] The following are some examples of Fig.10 How to design the specific structure of the coupling unit 400 according to the sizes of the BC segment and the DE segment so that the BC segment and the DE segment have the same direction of current distribution is further explained:

[0067] Optionally, the equivalent electrical length between the first feeding point 111 and the second end 113 of the first antenna radiator 110 is a first equivalent electrical length, the equivalent electrical length between the second feeding point 211 and the second end 213 of the second antenna radiator 210 is a second equivalent electrical length, and the operating wavelength of the first antenna 100 is a first wavelength;

[0068] Wherein, when the first equivalent electrical length is less than one quarter of the first wavelength, and the second equivalent electrical length is greater than one quarter of the first wavelength, the coupling unit 400 is a capacitor;

[0069] In the case where the first equivalent electrical length is greater than one quarter of the first wavelength, and the second equivalent electrical length is less than one quarter of the first wavelength, the coupling unit 400 is an inductor;

[0070] In the case where the first equivalent electrical length is greater than a quarter of the first wavelength, and the second equivalent electrical length is greater than a quarter of the first wavelength, the coupling unit 400 is a capacitor or an inductor;

[0071] In a case where the first equivalent electrical length is less than a quarter of the first wavelength, and the second equivalent electrical length is less than a quarter of the first wavelength, the coupling unit 400 is a capacitor or an inductor.

[0072] Among them, the first equivalent electrical length is Fig.10 The length of the BC segment in the above second equivalent electrical length is Fig.10 The length of the DE segment in . When the first equivalent electrical length is less than one-quarter of the first wavelength, the BC segment of the first antenna radiator 110 has a capacitive characteristic, and the BC segment can be regarded as a capacitive reactance. When the first equivalent electrical length is greater than one-quarter of the first wavelength, the BC segment of the first antenna radiator 110 has an inductive characteristic, and the BC segment can be regarded as an inductive reactance. Correspondingly, when the second equivalent electrical length is less than one-quarter of the first wavelength, the DE segment of the second antenna radiator 210 has a capacitive characteristic, and the DE segment can be regarded as a capacitive reactance. When the second equivalent electrical length is greater than one-quarter of the first wavelength, the DE segment of the second antenna radiator 210 has an inductive characteristic, and the DE segment can be regarded as an inductive reactance. The characteristics of ABC are consistent with those of the BC segment, that is, when the BC segment is a capacitive characteristic, ABC is a capacitive characteristic. The characteristics of ADE are: the characteristics presented by the superposition of the characteristics of the coupling unit 400 and the DE segment. Based on this, it can be determined that the coupling unit 400 is a capacitor or an inductor according to the capacitive or inductive characteristics of the BC segment and the DE segment.

[0073] For example, in some embodiments of the present application, when the first equivalent electrical length is less than one quarter of the first wavelength, and the second equivalent electrical length is greater than one quarter of the first wavelength, at this time, the BC segment has a capacitive characteristic, and the DE segment has an inductive characteristic. To ensure that the ABC and ADE impedances are both capacitive reactances at point A, it is necessary to set the coupling unit 400 as a capacitor, and the coupling unit 400 and the DE segment have a capacitive reactance characteristic after superposition. Since the ABC and ADE impedances are both capacitive reactances at point A, during the excitation of the first antenna 100, the BC segment and the DE segment can have a current distribution in the same direction.

[0074] In other embodiments of the present application, when the first equivalent electrical length is greater than one quarter of the first wavelength, and the second equivalent electrical length is less than one quarter of the first wavelength, at this time, the BC segment has an inductive characteristic, and the DE segment has a capacitive characteristic. To ensure that the ABC and ADE impedances are both inductive at point A, it is necessary to set the coupling unit 400 as an inductor, and the coupling unit 400 and the DE segment have an inductive characteristic after superposition. Since the ABC and ADE impedances are both inductive reactances at point A, during the excitation of the first antenna 100, the BC segment and the DE segment can have the same direction of current distribution.

[0075] In other embodiments of the present application, when the first equivalent electrical length is greater than one quarter of the first wavelength, and the second equivalent electrical length is greater than one quarter of the first wavelength, at this time, the BC segment has an inductive characteristic, and the DE segment has an inductive characteristic. At this time, the coupling unit 400 can be a small capacitor or a small inductor, and it is only necessary to ensure that the ABC and ADE impedances are both inductors at point A.

[0076] In other embodiments of the present application, when the first equivalent electrical length is less than one quarter of the first wavelength, and the second equivalent electrical length is less than one quarter of the first wavelength, at this time, the BC segment has a capacitive characteristic, and the DE segment has a capacitive characteristic. At this time, the coupling unit 400 can be a small capacitor or a small inductor, and it is only necessary to ensure that the ABC and ADE impedances are both capacitors at point A.

[0077] In this embodiment, the specific structure of the coupling unit 400 is designed based on the first equivalent electrical length and the second equivalent electrical length. In this way, during the excitation of the first antenna 100, it can be ensured that a unidirectional current can be excited between the second feeding point 211 and the second end 213 of the second antenna radiator 210 to improve the antenna performance of the first antenna 100.

[0078] Optionally, the operating frequency band of the first antenna 100 is the first operating frequency band, the operating frequency band of the second antenna 200 is the second operating frequency band, the minimum frequency value of the first operating frequency band is greater than the maximum frequency value of the second operating frequency band, and the first antenna radiator 110 is parallel to the second antenna radiator 210;

[0079] The first conductive member 130 is electrically connected to the first end 112 of the first antenna radiator 110. The first antenna 100 also includes a third conductive member 140, through which the first conductive member 130 is grounded. The second end 113 of the first antenna radiator 110 is the antenna end of the first antenna 100. The second antenna radiator 210 includes a second feeding point 211 for electrically connecting to the second conductive member 220. The second antenna 200 also includes a fourth conductive member 230, through which the first end 212 of the second antenna radiator 210 is grounded. The second end 213 of the second antenna radiator 210 is the antenna end of the second antenna 200. The second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located on two opposite sides of the first conductive member 130.

[0080] The first end 112 of the first antenna radiator 110 may form a feeding point of the first antenna 100 .

[0081] See also Fig.12 , Fig.12 The embodiment shown is in Figure 6 On the basis of the illustrated embodiment, the orientation of the first antenna radiator 110 is changed so that the second end 113 of the first antenna radiator 110 is located on two opposite sides of the first conductive member 130 instead of being located on the same side of the first conductive member 130 as the second end 213 of the second antenna radiator 210.

[0082] The above-mentioned antenna end refers to the endmost part of the antenna structure, usually refers to the physical end of the antenna radiator, and mostly refers to the floating end.

[0083] It can be understood that the first feeding unit 120 is electrically connected to the first end 112 of the first antenna radiator 110 through the first conductive plate, and the second feeding unit 240 is electrically connected to the second feeding point 211 through the second conductive plate.

[0084] The length direction of the first antenna radiator 110 may be the same as the length direction of the second antenna radiator 210. The second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located at two opposite sides of the first conductive member 130, which may specifically mean that the second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located at two opposite sides of a target plane passing through the first conductive member 130, wherein the target plane is perpendicular to the length direction of the first antenna radiator 110. The target plane passing through the first conductive member 130 specifically refers to a plane including at least one position point in the first conductive member 130 and perpendicular to the length direction of the first antenna radiator 110.

[0085] Specifically, see Fig.14 In some embodiments of the present application, the end of the first conductive member 130 connected to the first feeding unit 120 is point A, the first end 112 of the first antenna radiator 110 is point B, the second end 113 of the first antenna radiator 110 is point C, the second feeding point 211 is point D, and the second end 213 of the second antenna radiator 210 is point E. Fig.14 for Fig.12 The corresponding feeding coupling schematic diagram shows that for point A, when the ABC and ADE impedances have opposite polarities at point A, the currents of the BC segment and the DE segment are distributed in the same direction. Thus, the specific structure of the coupling unit 400 can be designed according to the sizes of the BC segment and the DE segment, so that the BC segment and the DE segment can have current distribution in the same direction.

[0086] The opposite polarity of the impedances ABC and ADE at point A may mean that: when ABC is capacitive, ADE is inductive; or, when ABC is inductive, ADE is capacitive. Fig.14 The third inductor 271 and the second capacitor 172 connected in parallel form a filter resonant circuit 270 in the following embodiment. Fig.14 The third capacitor 260 and the second inductor 250 in the second antenna 200 are used as a matching circuit. Fig.14 The first capacitor 160 and the first inductor 150 are used as a matching circuit for the first antenna 100. It can be understood that the first antenna 100 also includes the first matching circuit, and the second antenna 200 also includes the second matching circuit.

[0087] In this embodiment, since the second end 113 of the first antenna radiator 110 and the second end 213 of the second antenna radiator 210 are located at two opposite sides of the first conductive member 130, it is only necessary to make the polarities of the two antenna radiators at one end of the first conductive member 130 connected to the first feeding unit 120 opposite to each other, the two antenna radiators can have the same direction of current distribution, such as Fig.15 As shown, Fig.15 The direction indicated by the arrow in is the flow direction of the current, thereby improving the antenna performance of the first antenna 100.

[0088] The following are some examples of Fig.14 How to design the specific structure of the coupling unit 400 according to the sizes of the BC segment and the DE segment so that the BC segment and the DE segment have the same direction of current distribution is further explained:

[0089] Optionally, the equivalent electrical length between the first end 112 of the first antenna radiator 110 and the second end 113 of the first antenna radiator 110 is a first equivalent electrical length, the equivalent electrical length between the second feeding point 211 and the second end 213 of the second antenna radiator 210 is a second equivalent electrical length, and the operating wavelength of the first antenna 100 is a first wavelength;

[0090] Wherein, when the first equivalent electrical length is less than one quarter of the first wavelength, and the second equivalent electrical length is greater than one quarter of the first wavelength, the coupling unit 400 is a capacitor or an inductor;

[0091] In the case where the first equivalent electrical length is greater than one quarter of the first wavelength, and the second equivalent electrical length is less than one quarter of the first wavelength, the coupling unit 400 is a capacitor or an inductor;

[0092] In the case where the first equivalent electrical length is greater than a quarter of the first wavelength, and the second equivalent electrical length is greater than a quarter of the first wavelength, the coupling unit 400 is a capacitor;

[0093] In a case where the first equivalent electrical length is less than a quarter of the first wavelength, and the second equivalent electrical length is less than a quarter of the first wavelength, the coupling unit 400 is an inductor.

[0094] Among them, the first equivalent electrical length is Fig.14 The length of the BC segment in the above second equivalent electrical length is Fig.14The length of the DE segment in . When the first equivalent electrical length is less than one-quarter of the first wavelength, the BC segment of the first antenna radiator 110 has a capacitive characteristic, and the BC segment can be regarded as a capacitive reactance. When the first equivalent electrical length is greater than one-quarter of the first wavelength, the BC segment of the first antenna radiator 110 has an inductive characteristic, and the BC segment can be regarded as an inductive reactance. Correspondingly, when the second equivalent electrical length is less than one-quarter of the first wavelength, the DE segment of the second antenna radiator 210 has a capacitive characteristic, and the DE segment can be regarded as a capacitive reactance. When the second equivalent electrical length is greater than one-quarter of the first wavelength, the DE segment of the second antenna radiator 210 has an inductive characteristic, and the DE segment can be regarded as an inductive reactance. The characteristics of ABC are consistent with those of the BC segment, that is, when the BC segment is a capacitive characteristic, ABC is a capacitive characteristic. The characteristics of ADE are: the characteristics presented by the superposition of the characteristics of the coupling unit 400 and the DE segment. Based on this, it can be determined that the coupling unit 400 is a capacitor or an inductor according to the capacitive or inductive characteristics of the BC segment and the DE segment.

[0095] For example, in some embodiments of the present application, when the first equivalent electrical length is less than one quarter of the first wavelength and the second equivalent electrical length is greater than one quarter of the first wavelength, the BC segment has a capacitive characteristic and the DE segment has an inductive characteristic. To ensure that the ABC and ADE impedances have opposite polarities at point A, the coupling unit 400 can be a large capacitor or inductor. It is only necessary to ensure that the coupling unit 400 and the DE segment have inductive characteristics after superposition.

[0096] In other embodiments of the present application, when the first equivalent electrical length is greater than one quarter of the first wavelength and the second equivalent electrical length is less than one quarter of the first wavelength, the BC segment has an inductive characteristic and the DE segment has a capacitive characteristic. To ensure that the ABC and ADE impedances have opposite polarities at point A, the coupling unit 400 can be a capacitor or a small inductor. It is only necessary to ensure that the coupling unit 400 and the DE segment have capacitive characteristics after the characteristics are superimposed.

[0097] In other embodiments of the present application, when the first equivalent electrical length is greater than one quarter of the first wavelength, and the second equivalent electrical length is greater than one quarter of the first wavelength, at this time, the BC segment has an inductive characteristic, and the DE segment has an inductive characteristic. In order to ensure that the ABC and ADE impedances have opposite polarities at point A, the coupling unit 400 can be a small capacitor, and it is only necessary to ensure that the coupling unit 400 and the DE segment have capacitive characteristics after the characteristics are superimposed.

[0098] In other embodiments of the present application, when the first equivalent electrical length is less than one quarter of the first wavelength, and the second equivalent electrical length is less than one quarter of the first wavelength, at this time, the BC segment has a capacitive characteristic, and the DE segment has a capacitive characteristic. In order to ensure that the ABC and ADE impedances have opposite polarities at point A, the coupling unit 400 can be an inductor. It is only necessary to ensure that the coupling unit 400 and the DE segment have inductive characteristics after the characteristics are superimposed.

[0099] In this embodiment, the specific structure of the coupling unit 400 is designed based on the first equivalent electrical length and the second equivalent electrical length. In this way, during the excitation of the first antenna 100, it can be ensured that a unidirectional current can be excited between the second feeding point 211 and the second end 213 of the second antenna radiator 210 to improve the antenna performance of the first antenna 100.

[0100] Above Figures 3 to 15 In the embodiment shown, the low body SAR effect is achieved by spreading the current on the sides and back. Fig.16 In the head-hand scenario shown, after the first antenna 100 on the back is current-coupled to the side, the side is closer to the head, which will cause the head SAR value and head-hand derating in the head-hand state to become higher. Based on this, the embodiment of the present application further adds a switch 500 to the coupling unit 400 to reduce the SAR value in the head-hand scenario. Specifically:

[0101] Optionally, the coupling unit 400 includes a coupling element and a switch element 500, and the first conductive element 130, the coupling element, the switch element 500 and the second conductive element 220 are electrically connected in sequence; or, the coupling unit 400 includes a coupling element and a switch element 500, and the first conductive element 130, the switch element 500, the coupling element and the second conductive element 220 are electrically connected in sequence;

[0102] Wherein, when the receiver of the electronic device is in the on state, the switch element 500 is in the off state;

[0103] When the receiver of the electronic device is in a closed state, the switch element 500 is in a conducting state.

[0104] The coupling element is the capacitor or inductor in the above embodiment. The switch 500 can be any type of switch 500, and the switch 500 can be electrically connected to the circuit board, so that the on / off state of the switch 500 can be controlled based on the circuit board.

[0105] Specifically, the switch element 500 may be a separately provided switch element 500, or may be a switch element 500 already in the second antenna 200 that is reused. For example, see Fig.17 The switch 500 is a switch 500 already in the second antenna 200, and includes a ground terminal, an RFC terminal, an RF1 terminal, an RF2 terminal, and an RF3 terminal. The ground terminal is grounded, the RFC terminal is electrically connected to the second antenna radiator 210, the RF1 terminal is electrically connected to the coupling element, and the RF2 terminal is electrically connected to the second feeding unit 240 through the fourth capacitor 280. The RF3 terminal is electrically connected to the second capacitor 172. Among them, Fig.17 The third inductor 271 and the second capacitor 172 connected in parallel form a filter resonant circuit 270 in the following embodiment. Fig.17 The third capacitor 260 and the fourth capacitor 280 in the second antenna 200 are used as a matching circuit. Fig.17 The first capacitor 160 and the first inductor 150 in the circuit are used as the matching circuit of the first antenna 100. It can be understood that the first antenna 100 also includes the first matching circuit, and the second antenna 200 also includes the second matching circuit. In this way, the circuit board can control the on-off state between the coupling element and the second conductive member 220 by controlling the on-off state between the RFC terminal and the RF1 terminal.

[0106] The switch 500 is in the on state, which means that the RFC terminal is connected to the RF1 terminal, and at this time, the first antenna radiator 110 can be coupled to the second antenna radiator 210 through the coupling unit 400. The switch 500 is in the off state, which means that the RFC terminal is disconnected from the RF1 terminal, and at this time, the first antenna radiator 110 cannot be coupled to the second antenna radiator 210 through the coupling unit 400.

[0107] See also Fig.18 When the receiver of the electronic device is in the on state, the switch 500 in the coupling unit 400 is disconnected, and the current in the process of exciting the first antenna 100 is concentrated on the back of the electronic device, so that the first antenna 100 has both low head SAR and high performance. When the receiver of the electronic device is in the off state, the switch 500 in the coupling unit 400 is turned on, and the current in the process of exciting the first antenna 100 can be coupled to the side of the electronic device, so that the first antenna 100 has both low Body SAR and high performance.

[0108] In this embodiment, when the handset of the electronic device is in the on state, that is, the electronic device is in the head-hand mode, in order to reduce the amount of current coupled from the back of the electronic device to the side, the switch 500 can be controlled to be in the off state. At this time, the current in the first antenna radiator 110 cannot be coupled to the second antenna radiator 210 through the coupling unit 400, which is beneficial to reduce the amount of current coupled from the back of the electronic device to the side, thereby reducing the head SAR value in the head-hand mode. Correspondingly, when the handset of the electronic device is in the off state, that is, other modes other than the head-hand mode of the electronic device, at this time, the switch 500 can be controlled to be in the on state to enhance the coupling effect between the first antenna 100 and the second antenna 200, which is beneficial to improve the antenna performance of the first antenna 100.

[0109] Optionally, the second antenna 200 further includes a filter resonant circuit 270, and the second feeding unit 240 is electrically connected to the second antenna radiator 210 through the filter resonant circuit 270;

[0110] The filter resonant circuit 270 is used to block the antenna signal of the first working frequency band, and the filter resonant circuit 270 is used to conduct the antenna signal of the second working frequency band.

[0111] The filter resonant circuit 270 may be any resonant circuit that can block antenna signals in the first operating frequency band and conduct antenna signals in the second operating frequency band. The filter resonant circuit 270 may be a resonant circuit composed of components such as capacitors and inductors. For example, see Fig.10 In some embodiments of the present application, the filtering resonant circuit 270 includes a third inductor 271 and a second capacitor 172 connected in parallel.

[0112] It can be understood that the resonant frequency of the filter resonant circuit 270 is within the first working frequency band, and the resonant frequency of the filter resonant circuit 270 is outside the second working frequency band, so that it can be ensured that for the antenna signal of the first working frequency band, the filter resonant circuit 270 presents a high impedance to block the antenna signal of the first working frequency band. For the antenna signal of the second working frequency band, the filter resonant circuit 270 presents a low impedance to conduct the antenna signal of the second working frequency band.

[0113] In this embodiment, the second antenna 200 further includes a filter resonant circuit 270, and the second feeding unit 240 is electrically connected to the second antenna radiator 210 through the filter resonant circuit 270. In this way, during the excitation process of the first antenna 100, the antenna signal of the first antenna 100 cannot be transmitted to the second feeding unit 240 through the filter resonant circuit 270, so as to improve the isolation between the first antenna 100 and the second antenna 200. During the excitation process of the second antenna 200, the antenna signal of the second antenna 200 can be transmitted to the second antenna radiator 210 through the filter resonant circuit 270, so as to ensure that the working process of the second antenna 200 is not affected.

[0114] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
