Combining antennas that transmit and receive different frequency bands (e.g., 4G mobile communication antennas and 5G mobile communication antennas) with foldable housings to improve the competitiveness of terminal devices has become a development trend. However, foldable housings can be bent at the fold, and during this bending process, the antennas on the terminal device can be blocked by different hand grip postures, resulting in low antenna transmission and reception performance.

[0004] The terminal device provided in this disclosure includes at least:

[0005] A foldable housing having a conductive frame with at least two slits; wherein the at least two slits divide the conductive frame to form at least two antennas for transmitting and receiving at least two frequency bands;

[0006] When the housing is in the unfolded state, the two antennas that transmit and receive the same frequency band are symmetrically arranged with the center of the housing as the center of symmetry.

[0007] When the housing is in a folded state, the two antennas that transmit and receive the same frequency band are staggered.

[0008] In some embodiments, one of two adjacent antennas corresponds to a first feed point and a first ground point, and the other antenna corresponds to a second feed point and a second ground point;

[0009] The gap between two adjacent antennas is located between the first feed point and the second ground point;

[0010] The first feed point is located between the first ground point and the gap between the two adjacent antennas;

[0011] The second grounding point is located between the second feed point and the gap between the two adjacent antennas.

[0012] In some embodiments, the housing has a fold;

[0013] At least two of the fractures include: a first fracture and a second fracture located on the same side as the first fracture;

[0014] The first and second slits divide the conductive frame perpendicular to the fold into at least two antennas, which constitute a first antenna group, a second antenna group, and a third antenna group; the first antenna group, the second antenna group, and the third antenna group are all antenna groups that transmit and receive different frequency bands.

[0015] When the housing is in a folded state, the projections of the second antenna group and the third antenna group onto the first antenna group both coincide with the first antenna group.

[0016] In some embodiments, there are two first slits, both located at the fold and distributed on opposite sides of the housing.

[0017] In some embodiments, the first antenna group, the second antenna group, and the third antenna group each include: a first antenna and a second antenna that transmit and receive in the same frequency band, wherein the first antenna and the second antenna are parallel to each other and distributed on opposite sides of the housing.

[0018] In some embodiments, the first antenna group is a diversity antenna group for first-generation to fourth-generation mobile communication; the second antenna group is an antenna group for fifth-generation mobile communication; and the third antenna group is a dual-band antenna group; wherein the dual-band antenna group includes a global positioning system antenna and a wireless fidelity antenna.

[0019] In some embodiments, the housing has a fold;

[0020] At least two of the aforementioned fractures also include: a third fracture;

[0021] The third slit divides the conductive frame parallel to the fold into at least two antennas, and the at least two antennas constitute a fourth antenna group.

[0022] In some embodiments, the fourth antenna group includes a third antenna and a fourth antenna that transmit and receive in the same frequency band, the third antenna and the fourth antenna being parallel to each other and distributed on opposite sides of the housing.

[0023] In some embodiments, the fourth antenna group is an antenna group for fifth-generation mobile communication.

[0024] In some embodiments, the housing has a fold;

[0025] At least two of the aforementioned fractures also include: a fourth fracture;

[0026] The fourth seam is located at the angle between the conductive frame perpendicular to the fold and the conductive frame parallel to the fold.

[0027] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0028] The terminal device of this disclosure includes a foldable housing. When the housing is in the unfolded state, two antennas transmitting and receiving the same frequency band are symmetrically arranged with the center of the housing as the center of symmetry. When the housing is in the folded state, the two antennas transmitting and receiving the same frequency band are staggered. That is, on the one hand, the two antennas transmitting and receiving the same frequency band are symmetrically arranged on the conductive frames on opposite sides of the housing in the unfolded state. Based on the usage habits of the terminal device and the limited hand-holding area, when one antenna is blocked, the antenna transmitting and receiving the same frequency band on the other side can be unblocked. In this way, the transmission and reception of wireless signals through the unblocked antenna can reduce the reduction in antenna transmission and reception performance caused by holding the terminal device, and can improve the transmission and reception performance of the antenna in the terminal device in that frequency band. On the other hand, the staggered two antennas transmitting and receiving the same frequency band increase the distance on the housing in the folded state, which can improve the isolation between the two antennas transmitting and receiving the same frequency band, reduce the mutual interference between the two antennas transmitting and receiving the same frequency band, and thus also improve the transmission and reception performance of the antenna in the terminal device in that frequency band.

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0040] Figure 1 This is a schematic diagram of the structure of a terminal device according to an exemplary embodiment. Figure 1 .like Figure 1 As shown, the terminal device includes at least:

[0041] The foldable housing 101 has a conductive frame with at least two slits; wherein the at least two slits 102 divide the conductive frame to form at least two antennas 103 for transmitting and receiving at least two frequency bands;

[0042] When the housing 101 is in the unfolded state, the two antennas 103 that transmit and receive the same frequency band are symmetrically arranged with the center of the housing 101 as the center of symmetry.

[0043] When the housing 101 is in a folded state, the two antennas 103 that transmit and receive the same frequency band are staggered.

[0044] In this embodiment of the disclosure, the terminal device is a terminal device with a screen. The terminal device can be a wearable electronic device and a mobile terminal. The mobile terminal includes a mobile phone, a laptop or a tablet computer. The wearable electronic device includes a smartwatch or a smart bracelet. This embodiment of the disclosure does not impose any limitations.

[0045] The aforementioned foldable housing supports the screen of the terminal device. This screen is flexible and can fold along with the housing. Thus, when the housing is unfolded, the screen size of the terminal device is increased, providing a better viewing experience for the user; when the housing is folded, the area occupied by the terminal device is reduced, making it easier to carry.

[0046] In this embodiment of the disclosure, the housing has a fold, and the housing can be bent at the fold. The angle at which the housing can be bent at the fold is between 0 degrees and 180 degrees. For example, when the housing is in the unfolded state, the included angle between the housings on both sides of the fold is 180 degrees; when the housing is in the folded state, the included angle between the housings on both sides of the fold is 0 degrees.

[0047] The aforementioned housing has a conductive frame with at least two breaks. For example, the housing may be rectangular in shape, and the conductive frame along the long side of the housing may have at least two breaks; or, the conductive frame along the short side of the housing may have at least two breaks. This disclosure does not impose any limitations on the embodiments.

[0048] For example, the width of the gap may be in the range of 1.5 mm to 2 mm, and this disclosure does not limit it.

[0049] The aforementioned at least two slits separate the conductive frame to form at least two antennas capable of transmitting and receiving at least two frequency bands. The conductive frame adjacent to each slit can form one antenna. In this antenna, the conductive frame adjacent to each slit jointly transmits and receives wireless signals via electromagnetic coupling.

[0050] In this embodiment of the disclosure, in a mobile communication scenario where the antenna is used, the terminal device can establish communication with the base station by transmitting and receiving wireless signals through the antenna, thereby enabling communication between the terminal device and external devices. For example, the terminal device can be a smartphone, and the external device can be a tablet computer. Alternatively, the terminal device can be a tablet computer, and the external device can be a laptop computer; this embodiment of the disclosure does not impose any limitations.

[0051] Two of the at least two antennas of the aforementioned terminal device may be antennas that transmit and receive in the same frequency band; they may also be antennas that transmit and receive in different frequency bands, and this disclosure does not impose any limitations.

[0052] It should be noted that the number of slots can be equal to the number of antennas. For example, the number of slots and antennas can both be 4 or 5, and this disclosure does not impose any limitations.

[0053] In this embodiment, when the housing is in the unfolded state, the two antennas transmitting and receiving the same frequency band are symmetrically arranged with the center of the housing as the center of symmetry. That is, the two antennas transmitting and receiving the same frequency band are 180 degrees symmetrical with the center of the housing as the center of symmetry. In other words, in this embodiment, the two antennas transmitting and receiving the same frequency band are symmetrically arranged on opposite sides of the housing. Due to the limited hand-grip area, if one antenna is blocked by a hand, the antenna on the opposite side may remain unblocked, reducing the possibility of the other antenna being blocked.

[0054] When the housing is in a folded state, the two antennas transmitting and receiving the same frequency band are staggered. For example, the two antennas transmitting and receiving the same frequency band can be located at opposite ends on the same side of the folded housing, or they can be located on opposite sides of the folded housing. This disclosure does not impose any limitations on the embodiments.

[0055] It should be noted that the distance between two antennas transmitting and receiving in the same frequency band is positively correlated with the isolation between them. The greater the distance, the greater the isolation between the antennas transmitting and receiving in the same frequency band. Therefore, by staggering the two antennas transmitting and receiving in the same frequency band, the isolation between them can be increased, interference between them can be reduced, and the transmission and reception performance of the antennas can be improved.

[0056] In this embodiment of the present disclosure, during the use of the terminal device, the antenna formed by the conductive frame is easily blocked by different hand grip postures, which makes it easy for the antenna to absorb the wireless signals transmitted and received, reducing the amount of wireless signals radiated by the antenna and thus reducing the antenna's transmission and reception performance.

[0057] Based on this, the terminal device of this disclosure includes a foldable housing. When the housing is in the unfolded state, two antennas transmitting and receiving the same frequency band are symmetrically arranged with the center of the housing as the center of symmetry. When the housing is in the folded state, the two antennas transmitting and receiving the same frequency band are staggered. That is, on the one hand, the two antennas transmitting and receiving the same frequency band are symmetrically arranged on the conductive frames on opposite sides of the housing in the unfolded state. Based on the usage habits of the terminal device and the limited hand-holding area, when one antenna is blocked, the other antenna transmitting and receiving the same frequency band can be unblocked. In this way, by transmitting and receiving wireless signals through the unblocked antenna, the reduction in antenna transmission and reception performance caused by holding the terminal device can be reduced, thereby improving the transmission and reception performance of the antenna in the terminal device in that frequency band. On the other hand, the staggered two antennas transmitting and receiving the same frequency band increase the distance on the folded housing, thereby improving the isolation between the two antennas transmitting and receiving the same frequency band, reducing mutual interference between the two antennas transmitting and receiving the same frequency band, and further improving the transmission and reception performance of the antenna in the terminal device in that frequency band.

[0058] In some embodiments, such as Figure 2 As shown, in two adjacent antennas, one antenna corresponds to a first feed point 104a and a first ground point 105a, and the other antenna corresponds to a second feed point 104b and a second ground point 105b.

[0059] The gap between two adjacent antennas is located between the first feed point 104a and the second ground point 105b;

[0060] The first feed point 104a is located between the first ground point 105a and the gap between the two adjacent antennas;

[0061] The second grounding point 105b is located between the second feed point 104b and the gap between the two adjacent antennas.

[0062] In this embodiment of the disclosure, the first feed point is used to transmit a first electrical signal. The first electrical signal can be used to excite the antenna connected to the first feed point to transmit and receive wireless signals, and can also transmit the first electrical signal to the radio frequency module to complete the reception of wireless signals; the first ground point is the return point of the first electrical signal.

[0063] The second feed point is used to transmit the second electrical signal. The second electrical signal can be used to excite the antenna connected to the second feed point to transmit and receive wireless signals, and can also be transmitted to the radio frequency module to complete the reception of wireless signals; the second ground point is the return point of the second electrical signal.

[0064] The first feed point is located between the first ground point and the gap between two adjacent antennas. That is, relative to the first ground point, the first feed point is positioned close to the gap between two adjacent antennas. The second feed point is located between the second ground point and the gap between two adjacent antennas. That is, relative to the second feed point, the second ground point is positioned close to the gap between two adjacent antennas.

[0065] As can be seen, when the antenna connected to the first feed point transmits and receives wireless signals, the signal coupled to the conductive frame at the gap between two adjacent antennas will flow back directly to the second grounding point, which can increase the isolation between two adjacent antennas, reduce interference to adjacent antennas, and improve the transmission and reception performance of the terminal device.

[0066] In some embodiments, such as Figure 3 As shown, the housing 101 has a fold 106;

[0067] At least two of the fractures include: a first fracture A and a second fracture B located on the same side as the first fracture A;

[0068] The first slit A and the second slit B divide the conductive frame perpendicular to the fold 106 to form at least two antennas; the at least two antennas constitute a first antenna group, a second antenna group, and a third antenna group; the first antenna group, the second antenna group, and the third antenna group are all antenna groups that transmit and receive different frequency bands;

[0069] When the housing is in a folded state, the projections of the second antenna group and the third antenna group onto the first antenna group both coincide with the first antenna group.

[0070] In this embodiment of the disclosure, the conductive frame includes: a conductive frame perpendicular to the fold and a conductive frame parallel to the fold. The conductive frame perpendicular to the fold can be separated by a first slit and a second slit to form a first antenna group, a second antenna group, and a third antenna group.

[0071] It should be noted that the first fracture and the second fracture can be the same fracture or different fractures, and the embodiments disclosed herein are not limited thereto.

[0072] The first, second, and third antenna groups mentioned above are all antenna groups that transmit and receive signals at different frequency bands. When the housing is in the folded state, the projections of the second and third antenna groups onto the first antenna group coincide with the first antenna group. That is, the radiation lengths of the second and third antenna groups are both less than the radiation length of the first antenna group. Based on the negative correlation between antenna radiation length and the frequency of the transmitted and received wireless signals, the corresponding transmission and reception frequencies of the second and third antenna groups are both greater than the transmission and reception frequency of the first antenna group.

[0073] For example, the first antenna group can be used to transmit and receive wireless signals in the B1 band, the second antenna group can be used to transmit and receive wireless signals in the B39 band, and the third antenna group can be used to transmit and receive wireless signals in the 5G band. This disclosure does not limit the scope of the embodiments.

[0074] In this embodiment of the disclosure, when the first antenna module, the second antenna module, and the third antenna module transmit and receive wireless signals, the first antenna group, the second antenna group, and the third antenna group transmit and receive wireless signals in different frequency bands. This can reduce the mutual interference between the first antenna group, the second antenna group, and the third antenna group caused by the first antenna group, which is formed perpendicular to the conductive frame, moving closer to the second antenna group and the third antenna group when the housing is in a folded state. This improves the isolation between the first antenna group, the second antenna group, and the third antenna group.

[0075] In some embodiments, such as Figure 3 As shown, there are two first seams A, both located at the fold 106 and distributed on opposite sides of the shell 101.

[0076] In this embodiment of the disclosure, two first slits are provided at the fold, which can reduce the number of bends that the conductive frame needs to withstand at the fold and extend the usage time of the terminal device.

[0077] In some embodiments, such as Figure 3 As shown, the first antenna group, the second antenna group and the third antenna group each include: a first antenna 103a and a second antenna 103b that transmit and receive in the same frequency band. The first antenna 103a and the second antenna 103b are parallel to each other and distributed on opposite sides of the housing.

[0078] In this embodiment, the first antenna group, the second antenna group, and the third antenna group each include a first antenna and a second antenna that transmit and receive the same frequency band. These first and second antennas are parallel to each other and distributed on opposite sides of the housing. When the housing is in the unfolded state, the first and second antennas are symmetrically arranged with the center of the housing as the center of symmetry; when the housing is in the folded state, they are staggered. Therefore, on the one hand, when the housing is in the unfolded state, if one antenna transmitting and receiving the same frequency band is blocked, the possibility of the other antenna being blocked is reduced, thus improving the terminal device's ability to transmit and receive wireless signals in that frequency band. On the other hand, the staggered arrangement of the two antennas transmitting and receiving the same frequency band increases the distance between them on the folded housing, improving the isolation between the first and second antennas, reducing mutual interference, and also improving the terminal device's transmission and reception performance in that frequency band.

[0079] In some embodiments, the first antenna group is a diversity antenna group for first-generation to fourth-generation mobile communication; the second antenna group is an antenna group for fifth-generation mobile communication; and the third antenna group is a dual-band antenna group; wherein the dual-band antenna group includes a global positioning system antenna and a wireless fidelity antenna.

[0080] In this embodiment of the disclosure, the diversity antenna group for first-generation to fourth-generation mobile communication is an antenna group capable of transmitting and receiving 2G, 3G, and 4G frequency bands. The antenna group for fifth-generation mobile communication is an antenna group capable of transmitting and receiving 5G frequency bands. The GPS antenna and the Wi-Fi antenna in this dual-band antenna group can share a single conductive frame for transmitting and receiving wireless signals. In this embodiment of the disclosure, the use of the GPS antenna or the Wi-Fi antenna for transmitting and receiving wireless signals can be switched by adjusting the on / off state of a switching component.

[0081] In some embodiments, such as Figure 4 As shown, the housing 101 has a fold 106;

[0082] At least two of the aforementioned fractures also include: a third fracture C;

[0083] The third slit C separates the conductive frame parallel to the fold 106 to form at least two antennas, and the at least two antennas constitute a fourth antenna group.

[0084] In this embodiment, the conductive frame parallel to the fold is adjacent to the conductive frame perpendicular to the fold. That is, the first antenna group, the second antenna group, and the third antenna group can be located on an adjacent conductive frame, and the fourth antenna group can be located on another adjacent conductive frame.

[0085] In this embodiment, an antenna group can be formed not only on the conductive frame perpendicular to the fold, but also on the conductive frame parallel to the fold, making the antenna group configuration more flexible.

[0086] In some embodiments, the fourth antenna group includes a third antenna and a fourth antenna that transmit and receive in the same frequency band, the third antenna and the fourth antenna being parallel to each other and distributed on opposite sides of the housing.

[0087] In this embodiment of the present disclosure, when the housing is in a folded state, the projection of the third antenna onto the fourth antenna is offset from the fourth antenna, which can prevent the two antennas transmitting and receiving the same frequency band from interfering with each other and improve the isolation between the two antennas transmitting and receiving the same frequency band.

[0088] In some embodiments, the fourth antenna group is an antenna group for fifth-generation mobile communication.

[0089] In some embodiments, the housing has a fold;

[0090] At least two of the aforementioned fractures also include: a fourth fracture;

[0091] The fourth seam is located at the angle between the conductive frame perpendicular to the fold and the conductive frame parallel to the fold.

[0092] In this embodiment, the fourth break is set at the angle between the conductive frame perpendicular to the fold and the conductive frame parallel to the fold, so that the break can be set not only at the fold but also at the angle, which can improve the flexibility of the break setting.

[0093] To facilitate understanding of the embodiments of this disclosure, a foldable screen mobile phone is used as an example. Figure 5As shown, the foldable phone includes a first screen that folds along with the foldable casing 201 and two non-foldable second screens 202. The first screen is located on the inside of the folded side of the phone. When the phone is unfolded, the first screen is exposed, allowing the phone to display in full screen for a better viewing experience. The two second screens 202 are located on the outside of the foldable phone, and a camera module 203 is positioned between the two second screens 202. When the phone is folded, the camera module 203 can be used to take selfies. The two second screens 202 located on either side of the camera module 203 can display two selfie effects, such as a panoramic effect, a wide-angle effect, and different beauty effects. Thus, when the phone is folded, selfies can be taken directly using the camera module without unfolding the phone. In addition, the two second screens can display two different selfie effects, allowing users to directly select the better effect to save, eliminating the need to take multiple photos and then select and delete photos from the album.

[0094] like Figure 6 As shown, when the phone is in the unfolded state, the first screen 204 and the second screen 202 are located on opposite sides of the phone. The first screen 204 and the two second screens 202 can be used to display the same image or different images; this embodiment does not impose limitations. During shooting, the camera module between the two second screens can be used to photograph a person facing the second screen, enabling self-portraits in addition to phone selfies. The shooting effect can be displayed on the first screen and the two second screens. Thus, by using the different shooting effects on the three screens, the best shooting effect can be directly selected without needing to take multiple shots and then manually select and delete photos from the album.

[0095] In this embodiment of the present disclosure, a gap may be provided at the conductive frame of the foldable mobile phone. In the unfolded state, a first gap and a second gap are respectively provided on two opposing conductive frames perpendicular to the fold of the mobile phone. The first gap is located at the fold, and the second gap is adjacent to the first gap. In the unfolded state, a third gap is respectively provided on two opposing conductive frames parallel to the fold of the mobile phone. A fourth gap is provided at the angle between the conductive frames perpendicular to and parallel to the conductive frames.

[0096] like Figure 7 As shown, eight antennas can be formed by adding eight slits to the conductive frame. These eight antennas can cover the communication frequency bands of 2G, 3G, 4G, or 5G. For example, the eight antennas can be two first-generation to fourth-generation mobile communication diversity antennas, four fifth-generation mobile communication antennas, and two dual-band antennas.

[0097] Because the eight antennas operating at the same frequency band are symmetrically arranged around the center of the housing when the housing is unfolded, and staggered when the housing is folded, this arrangement reduces the likelihood of one antenna being blocked when the terminal is held in different ways, thus improving the performance of the terminal in that frequency band and conforming to user hand-holding habits. Simultaneously, the staggered arrangement of the two antennas operating at the same frequency band increases the distance between them on the folded housing, improving isolation and reducing interference between them, thereby also enhancing the transmission and reception performance of the antennas in that frequency band.

[0098] It should be noted that the terms "first", "second", "third" and "fourth" in the embodiments of this disclosure are for ease of description and distinction only, and have no other specific meaning.
