[0033] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0034] In order to better understand the technical solutions of the present application, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] The non-terrestrial network (NTN: Non Terrestrial Network) technology refers to a technology for communicating by using a non-terrestrial network, wherein the non-terrestrial network refers to a network taking a non-terrestrial flying object as a transmission device relay node or a base station. The NTN technology can not be limited by the topography, and can provide ubiquitous coverage capability, connect the multi-dimensional space of air, sky, land and sea, form an integrated ubiquitous access network, and realize all-scenario on-demand access.

[0036] Satellite communication belongs to one of the non-terrestrial network technologies, and is an important component of the next stage of 5G (5th Generation Mobile Communication Technology) or even 6G (6th Generation Mobile Communication Technology). In related technologies, terminal products with satellite communication functions have been mass-produced. However, in many cases, the terminal products need to adjust the terminal angle to point to the satellite to realize satellite communication, and need to be in an environment without obvious obstruction to realize real-time satellite communication. At the same time, during the call process using satellite communication, there are often interruptions and large delays, and the call quality is not high, and there is a situation of poor communication quality and high delay.

[0037] As an essential part of the communication system, the directivity and gain of the antenna determine the limit value of the transceiving signal in a specific angle range. Therefore, the quality of the satellite real-time communication function in the terminal device is closely related to the directivity and gain of the antenna. To realize high-quality satellite real-time communication function, the directivity and gain of the terminal antenna can be improved first.

[0038] In related technologies, the satellite communication antenna of the terminal device is mostly multiplexed with the internal high-frequency antenna, resulting in low gain of the antenna and deviation of the directivity, which is not completely directed to the top of the terminal device, and is easy to affect the satellite communication quality of the terminal device.

[0039] To solve the above problems, the present application provides a solution. The present application provides an antenna gain device, an antenna module and a terminal device. The amplification radiator of the antenna gain device cooperates with the non-terrestrial network antenna of the antenna module. At the same time, the amplification radiator and the non-terrestrial network antenna are located on the same plane and on the side of the main radiation direction of the non-terrestrial network antenna, and the distance between the amplification radiator and the non-terrestrial network antenna corresponds to the working frequency band of the non-terrestrial network antenna.

[0040] The solution provided by the embodiments of the present application can enhance the gain of the non-terrestrial network antenna and ensure the directivity of the antenna, and improve the non-terrestrial network communication quality of the terminal device.

[0041] The antenna module is arranged in the terminal device, so the terminal device can be any device that needs to communicate through an antenna, and can be a computing service device with data processing, network communication and program running functions, such as a server, a network terminal, a PC (Personal Computer), an embedded computer, an industrial computer, etc., or an electronic device capable of realizing the above functions, such as a mobile phone, a tablet computer, a notebook computer, a wearable device, a vehicle-mounted terminal, etc.

[0042] The antenna gain device can be used as an external accessory in cooperation with the antenna module of the terminal device, or can be an internal component of the terminal device and be arranged in the terminal device. The antenna gain device cooperates with the antenna module in the terminal device, and can be selected as needed, which is not limited in the application.

[0043] In order to better understand the technical solutions of the embodiments of the application, the following will be described in detail in combination with the drawings of the specification and specific embodiments.

[0044] The antenna gain device provided by the embodiments of the application can include a carrier and an amplification radiator. The amplification radiator is arranged on the carrier and is used to cooperate with a non-terrestrial network antenna.

[0045] The deviation between the plane where the amplification radiator is located and the plane where the non-terrestrial network antenna is located is within a preset threshold range. The amplification radiator is located on the side of the main radiation direction of the non-terrestrial network antenna, and the distance between the amplification radiator and the non-terrestrial network antenna corresponds to the working frequency band of the non-terrestrial network antenna.

[0046] The carrier is used to carry the amplification radiator. The amplification radiator can be arranged on the carrier or in the carrier, which is not limited here. In order to avoid interference with the antenna signal, the carrier can be made of various non-metal materials. The amplification radiator can be made of a good conductor metal material, such as magnesium-aluminum alloy, nickel-plated steel, etc. The amplification radiator can be arranged in a long strip shape and cooperate with the non-terrestrial network antenna.

[0047] The non-terrestrial network antenna can be an antenna in an antenna module of a terminal device. The antenna module refers to a module composed of at least one antenna system arranged in the terminal device. The antenna module can include a non-terrestrial network antenna, a mobile communication main antenna, a WIFI antenna, a near-field communication antenna, etc., which is not limited here. The non-terrestrial network antenna refers to an antenna system used to support non-terrestrial network communication. The non-terrestrial network can be a satellite communication network, a UAV communication network, a high-altitude platform communication network, etc. The embodiments take the satellite antenna as an example to illustrate the non-terrestrial network antenna. In some embodiments, the non-terrestrial network antenna can be a metal frame antenna arranged at the top of the terminal device.

[0048] Referring to FIG. 1, FIG. 1 is a structural schematic diagram of an antenna gain device 2 provided by a first embodiment of the application, specifically, a top view of the antenna gain device 2; the plane where the amplification radiator is located refers to a plane parallel to the plane where FIG. 1 is located and where the geometric center of the amplification radiator 21 is located, and the plane where the non-terrestrial network antenna is located refers to a plane parallel to the plane where FIG. 1 is located and where the geometric center of the non-terrestrial network antenna is located. The plane where the amplification radiator is located can be parallel to the plane where the non-terrestrial network antenna is located, or there can be a certain angle. When the plane where the amplification radiator is located is parallel to the plane where the non-terrestrial network antenna is located, the deviation refers to the distance between the two planes; when the plane where the amplification radiator is located and the plane where the non-terrestrial network antenna is located have a certain angle, the deviation refers to the angle between the two planes. That is, the amplification radiator 21 and the non-terrestrial network antenna can be located in the same plane or approximately in the same plane; in an embodiment, the amplification radiator 21 and the non-terrestrial network antenna are located in the same plane, that is, the deviation between the plane where the amplification radiator is located and the plane where the non-terrestrial network antenna is located is zero.

[0049] In an embodiment of the present embodiment, the carrier can be configured as a protective shell of the terminal device, or configured as a shell of the terminal device, or arranged on the shell.

[0050] The shell of the terminal device refers to the shell component of the terminal device body, and the carrier can be a protective shell, a protective sleeve and the like of the terminal device, or a shell and the like of the terminal device, or a separate part arranged on the shell to facilitate fixing of the amplification radiator, which can be selected as needed in actual application, and the present embodiment is not limited in particular. Correspondingly, the amplification radiator arranged on the carrier can be arranged on the carrier or arranged in the carrier, for example, embedded in the protective shell, which is not limited in particular herein.

[0051] For example, the carrier can be various non-metal materials, such as silica gel, plastic, glass, leather, TPU (thermoplastic polyurethane elastomer) and the like, among which, the TPU material is preferred, which has good impact resistance, scratch resistance and waterproof performance, good wear resistance, and at the same time, the material is relatively light and thin, and can maintain the slim feel of the portable terminal device such as a mobile phone.

[0052] Referring to FIG. 1 and FIG. 2, FIG. 2 is a structural schematic diagram of an antenna module 1 provided by an embodiment of the application; in the present embodiment, the antenna gain device 2 includes a carrier 20 and an amplification radiator 21, the carrier 20 is a protective shell of the terminal device, the non-terrestrial network antenna of the antenna module 1 is a satellite antenna 11, and the amplification radiator 21 cooperates with the satellite antenna 11.

[0053] Continuing to refer to FIG. 1, the amplification radiator 21 is located in the same plane as the satellite antenna 11 and on the side of the main radiation direction of the satellite antenna 11. Because the top of the terminal device is usually taken as the main direction when the user uses the terminal device, the satellite antenna 11 of the embodiment is specifically arranged on the top of the terminal device, and the amplification radiator 21 is also located on the side of the top direction of the satellite antenna 11, that is, above the satellite antenna 11 and specifically arranged inside the top end of the carrier 20, that is, the protective shell. As shown in FIG. 1, a clearance distance is arranged between the amplification radiator 21 and the satellite antenna 11, and the spacing between the amplification radiator 21 and the satellite antenna 11 corresponds to the working frequency band of the satellite antenna 11, that is, the spacing between the two can be arranged according to the working frequency band of the satellite antenna 11, for example, a specific value or a threshold range is arranged according to the wavelength corresponding to the working frequency band, which can be selected as needed in actual application, and is not specifically limited here.

[0054] The amplification radiator is located in the same plane as the non-terrestrial network antenna and on the side of the main radiation direction of the non-terrestrial network antenna, which can make the energy concentration of the non-terrestrial network antenna in the main radiation direction higher, enhance the radiation or reception capability of the non-terrestrial network antenna in the main radiation direction, make it more concentrated on signal transmission or reception in the main radiation direction, improve the strength and quality of the signal in the main radiation direction, and thus ensure the directivity of the non-terrestrial network antenna.

[0055] The spacing between the amplification radiator and the non-terrestrial network antenna corresponds to the working frequency band of the non-terrestrial network antenna. On the one hand, the induced electric field phase characteristic of the amplification radiator is capacitive, so that the electric field phase of the amplification radiator lags behind the electric field phase of the non-terrestrial network antenna. On the other hand, the distance difference from the far field to the amplification radiator and the non-terrestrial network antenna causes a phase difference, so that in the far field radiation direction, the electric field phase of the amplification radiator leads the electric field phase of the non-terrestrial network antenna. In the working frequency band of the non-terrestrial network antenna, the lagging phase and the leading phase of the amplification radiator cancel each other out, so that the electric field of the non-terrestrial network antenna in the main radiation direction is superimposed, and the antenna gain in this direction is improved.

[0056] The embodiment provides an antenna gain device, which includes an amplification radiator and a carrier. The amplification radiator is arranged on the carrier and cooperates with a non-terrestrial network antenna. The amplification radiator is located in the same plane as the non-terrestrial network antenna and on the side of the main radiation direction of the non-terrestrial network antenna, which improves the strength and quality of the signal in the main radiation direction and thus ensures the directivity of the non-terrestrial network antenna. Meanwhile, the spacing between the amplification radiator and the non-terrestrial network antenna corresponds to the working frequency band of the non-terrestrial network antenna, which improves the antenna gain in this direction. Therefore, the antenna gain device can enhance the gain of the non-terrestrial network antenna and ensure the antenna directivity, and can improve the non-terrestrial network communication quality of the terminal device.

[0057] In an implementation, the distance between the amplification radiator and the non-terrestrial network antenna is greater than or equal to 0.05 times the wavelength of the target frequency band and less than or equal to 0.1 times the wavelength of the target frequency band; wherein the target frequency band is the working frequency band of the non-terrestrial network antenna.

[0058] The inductive electric field phase characteristic of the amplification radiator is capacitive, so that the electric field phase of the amplification radiator lags behind the electric field phase of the non-terrestrial network antenna; in order to realize that in the far field radiation direction, the electric field phase of the amplification radiator leads the electric field phase of the non-terrestrial network antenna to offset the aforementioned lagging phase, the distance between the amplification radiator and the non-terrestrial network antenna can be adjusted and the range value is set.

[0059] For example, the range value of the distance can be calculated by using the phase lag formula. The specific derivation process is as follows:

[0060] Firstly, the phase lag formula is determined as follows:

[0061] wherein, represents the lagging phase of the amplification radiator, λ represents the wavelength, c is the speed of light, f is the frequency, and d represents the distance between the amplification radiator and the non-terrestrial network antenna;

[0062] Then, according to the deformation of the phase lag formula, the following formula can be obtained:

[0063] Finally, according to the wavelength λ corresponding to the working frequency band of the non-terrestrial network antenna, the range of the distance d between the amplification radiator and the non-terrestrial network antenna is determined as follows: 0.05λ≤d≤0.1λ.

[0064] When the distance d between the amplification radiator and the satellite antenna 11 in FIG. 1 is between 0.05λ and 0.1λ, the leading phase of the amplification radiator in the far field radiation direction can offset the electric field lagging phase of the amplification radiator.

[0065] In the embodiment, the distance setting mode and range between the amplification radiator and the non-terrestrial network antenna are provided. By adjusting the distance between the amplification radiator and the non-terrestrial network antenna, it can be ensured that the lagging phase and the leading phase of the amplification radiator are offset in the working frequency band of the non-terrestrial network antenna, so as to ensure the antenna gain of the non-terrestrial network antenna in the main radiation direction; at the same time, based on the adjustable distance between the amplification radiator and the non-terrestrial network antenna, the gain of the non-terrestrial network antenna can be adjusted.

[0066] In another possible implementation, the length of the amplification radiator is greater than or equal to 0.25 times the wavelength of the target frequency band and less than or equal to 0.5 times the wavelength of the target frequency band; and the target frequency band is the operating frequency band of the non-terrestrial network antenna.

[0067] When the operating frequency band of the non-terrestrial network antenna is determined, the corresponding half wavelength and quarter wavelength can be calculated, and a range greater than or equal to the quarter wavelength and less than or equal to the half wavelength is obtained as the length range of the amplification radiator.

[0068] For example, the length range of the amplification radiator can be calculated by using the wavelength formula. The specific derivation process is as follows: first, the operating frequency band of the non-terrestrial network antenna is determined; then, the wavelength λ corresponding to the operating frequency band of the non-terrestrial network antenna is obtained according to the wavelength formula ; and finally, the length L of the amplification radiator is determined to be in the range of 0.25λ≤L≤0.5λ.

[0069] Referring to FIG. 3, FIG. 3 is another structural schematic diagram of the antenna gain device 2 provided by the first embodiment of the antenna gain device of the present application. As shown in FIG. 1, the length of the amplification radiator 21 can be adjusted as needed. In FIG. 1, the length of the amplification radiator 21 is relatively long, and in FIG. 3, the length of the amplification radiator 21 is relatively short.

[0070] When the length L of the amplification radiator 21 is in the range of 0.25λ and 0.5λ, the amplification radiator 21 generates an induced electric field, and the phase characteristic of the induced electric field is capacitive, so that the electric field phase of the amplification radiator 21 lags behind the electric field phase of the satellite antenna 11. At the same time, the distance from the far-field observation point to the amplification radiator 21 is less than the distance to the satellite antenna 11, and the distance difference causes a phase difference. In the far-field zenith direction, the electric field phase of the amplification radiator 21 leads the electric field phase of the satellite antenna 11, so that in the operating frequency band of the satellite antenna 11, the lagging phase and the leading phase of the amplification radiator 21 are offset, the electric fields are superimposed in the zenith direction of the satellite antenna 11, and the gain of the satellite antenna 11 is improved. That is, the amplification radiator 21 has a gain improvement effect on the satellite antenna 11.

[0071] In the present embodiment, the length setting mode and range of the amplification radiator are provided, and the non-terrestrial network antenna can have a gain improvement effect in the operating frequency band by adjusting the size of the amplification radiator. At the same time, the length of the amplification radiator can be adjusted to realize the gain adjustment of the non-terrestrial network antenna.

[0072] In yet another possible implementation, the amplification radiator includes a straight section and at least one bending section.

[0073] The straight line segment is parallel to the arrangement direction of the non-ground network antenna, and the bending segment is connected to any one of the two ends of the straight line segment and extends towards the non-ground network antenna.

[0074] Due to the size, specifications and the like of the terminal device, the length of the amplification radiator when achieving the best gain effect may exceed the width of the terminal device, resulting in the need to shorten the amplification radiator, causing the antenna gain to decrease. In order to avoid this problem, the amplification radiator can be provided as a multi-segment foldable structure, that is, the amplification radiator can include a straight line segment and at least one bending segment. The straight line segment is parallel to the arrangement direction of the non-ground network antenna, and the bending segment is connected to any one of the two ends of the straight line segment and extends towards the non-ground network antenna. In some embodiments, the straight line segment and the bending segment are both good conductor metal materials. When the carrier is a protective shell, the straight line segment is arranged inside the top end of the carrier, i.e., the protective shell, and correspondingly, the bending segment is also arranged inside the protective shell, but is located in the zenith direction of the antenna module.

[0075] Referring to FIG. 4, FIG. 4 is another structural schematic diagram of the antenna gain device 2 provided by the first embodiment of the application. In this embodiment, the amplification radiator 21 includes a straight line segment 211 and two bending segments 212. The straight line segment 211 is parallel to the arrangement direction of the satellite antenna 11, which can be arranged along the transverse direction of the terminal device or the protective shell, so that the straight line segment 211 is also arranged along the transverse direction of the terminal device or the protective shell. The two bending segments 212 are respectively connected to the two ends of the straight line segment 211 and both extend towards the satellite antenna 11, that is, the straight line segment 211 is arranged at the top of the terminal device or the protective shell, and the two bending segments 212 both extend towards the satellite antenna 11 in the antenna module 1, that is, extend towards the bottom of the terminal device or the protective shell. As shown in FIG. 4, when the bending segment 212 extends towards the satellite antenna 11, it naturally forms an angle with the straight line segment 211. In order to occupy less space and ensure the installation convenience of the amplification radiator 21, the bending segment 212 can be perpendicular to the straight line segment 211. In actual application, the amplification radiator 21 can be an integrated structure, and the straight line segment 211 and the bending segment 212 can be obtained by bending the amplification radiator 21.

[0076] In this embodiment, the amplification radiator includes a straight line segment and at least one bending segment, constituting a foldable amplification radiator. The length of the amplification radiator can be lengthened without increasing the transverse width of the terminal device or the carrier, thereby further improving the gain of the non-ground network antenna and meeting some scenarios where the transverse length of the amplification radiator is limited.

[0077] Based on the first embodiment of the antenna gain device, in the second embodiment of the antenna gain device, the same or similar contents as the above embodiments can be referred to the above introduction, and the subsequent will not be described. On this basis, the antenna gain device can further include a side radiation body; wherein the side radiation body is arranged on the carrier and is opposite to and spaced apart from the amplification radiation body, so that the deviation between the plane where the side radiation body is located and the plane where the non-terrestrial network antenna is located is within a preset threshold range, and the side radiation body is located on the opposite side of the main radiation direction of the non-terrestrial network antenna.

[0078] The side radiation body is opposite to and spaced apart from the amplification radiation body, the amplification radiation body is located on the side of the main radiation direction of the non-terrestrial network antenna, and the side radiation body is located on the opposite side of the main radiation direction of the non-terrestrial network antenna, that is, the amplification radiation body and the side radiation body are respectively located on the opposite sides of the non-terrestrial network antenna. The side radiation body can be integrated with the amplification radiation body in the carrier such as a protective shell or a shell of a terminal device, or can be separately arranged, such as arranging the amplification radiation body in the protective shell and arranging the side radiation body in the shell of the terminal device as a part of the terminal device. The specific selection can be made according to actual needs, which is not limited here.

[0079] Referring to FIG. 5, FIG. 5 is a structural schematic diagram of the antenna gain device 2 provided by the second embodiment of the antenna gain device, specifically a top view schematic diagram of the antenna gain device 2; the plane where the side radiation body is located refers to the plane where the geometric center of the side radiation body 22 is located, which is parallel to the plane of FIG. 5. The plane where the side radiation body is located can be parallel to the plane where the non-terrestrial network antenna is located, or there can be a certain angle. When the plane where the side radiation body is located is parallel to the plane where the non-terrestrial network antenna is located, the deviation refers to the distance between the plane where the side radiation body is located and the plane where the non-terrestrial network antenna is located; when the plane where the side radiation body is located and the plane where the non-terrestrial network antenna is located exist a certain angle, the deviation refers to the angle between the plane where the side radiation body is located and the plane where the non-terrestrial network antenna is located. That is, the side radiation body 22 and the non-terrestrial network antenna can be located on the same plane or approximately on the same plane; in an embodiment, the side radiation body 22 and the non-terrestrial network antenna are located on the same plane, that is, the deviation between the plane where the side radiation body is located and the plane where the non-terrestrial network antenna is located is zero; when the side radiation body 22 and the non-terrestrial network antenna are located on the same plane, the side radiation body 22 and the amplification radiation body 21 are also located on the same plane.

[0080] The principle of the side radiation body and the amplification radiation body is similar, which can offset the radiation of the non-terrestrial network antenna in the opposite direction of the main radiation direction in the working frequency band of the non-terrestrial network antenna, thereby indirectly improving the antenna gain of the non-terrestrial network antenna in the main radiation direction.

[0081] As shown in FIG. 5, in the embodiment, the opposite-side radiator 22 is arranged on the opposite side of the main radiation direction of the satellite antenna 11, i.e., below the satellite antenna 11, and is flush with the height of the satellite antenna 11 and the amplification radiator 21, which can offset the radiation in the bottom direction of the satellite antenna 11, thereby indirectly improving the gain of the satellite antenna 11 in the zenith direction.

[0082] The embodiment provides an antenna gain device, which comprises an amplification radiator and an opposite-side radiator, the amplification radiator is arranged on the side of the main radiation direction of the non-ground network antenna, and the opposite-side radiator is arranged on the opposite side of the main radiation direction of the non-ground network antenna, and the two can make the energy concentration of the non-ground network antenna in the main radiation direction higher, thereby further ensuring the directivity of the non-ground network antenna; the amplification radiator has a spacing from the non-ground network antenna, and the opposite-side radiator is spaced apart from the amplification radiator, so that the electric field of the non-ground network antenna in the main radiation direction is superposed, the antenna gain in the main radiation direction can be directly improved, and the electric field in the opposite side of the main radiation direction is also superposed, the antenna gain in the main radiation direction can be indirectly improved, thereby realizing higher gain of the non-ground network antenna, and further improving the non-ground network communication quality of the terminal device.

[0083] In a feasible implementation, the length of the opposite-side radiator is greater than or equal to 0.5 times the wavelength of the target frequency band and less than or equal to 0.6 times the wavelength of the target frequency band; wherein the target frequency band is the working frequency band of the non-ground network antenna.

[0084] When the working frequency band of the non-ground network antenna is determined, the length value range of the opposite-side radiator can be calculated by using the wavelength formula, and specifically, the range of the length L2 of the opposite-side radiator can be determined according to the wavelength λ corresponding to the working frequency band of the non-ground network antenna as: 0.5λ≤L2≤0.6λ.

[0085] When the length L2 of the opposite-side radiator 22 in FIG. 5 is valued between 0.5λ and 0.6λ, the radiation in the bottom direction of the satellite antenna 11 can be offset in the working frequency band of the satellite antenna 11, thereby indirectly improving the gain of the satellite antenna 11 in the zenith direction.

[0086] In this embodiment, the length of the opposite-side radiator is significantly longer than the length of the amplification radiator. Since the transverse side of many terminal devices is shorter than the side, such as a vertical screen mobile phone, in some embodiments, the amplification radiator has to be bent to meet the length range to ensure the gain effect, and the opposite-side radiator may not be set according to the above setting range, which will cause the gain effect to be reduced or not to reach the best. In this regard, the arrangement direction of the non-terrestrial network antenna in the antenna module can be parallel to the longer side of the terminal device, or the length of the transverse side of the terminal device can be greater than the length of the opposite-side radiator, that is, the terminal device can be a horizontal screen mobile phone with a longer transverse side, a folded screen mobile phone with a long enough transverse side after unfolding, a device with a long enough transverse side and a shorter side than the transverse side, such as a tablet computer, and the like, so that the transverse side of the terminal device is long enough to ensure that the length of the opposite-side radiator is between 0.5λ and 0.6λ, thereby reaching the optimal antenna gain.

[0087] In this embodiment, the length of the opposite-side radiator is set in a manner and range, and the non-terrestrial network antenna can have a better gain improvement effect in its working frequency band by adjusting the size of the opposite-side radiator; at the same time, the gain of the non-terrestrial network antenna can be adjusted based on the adjustable length of the opposite-side radiator.

[0088] The embodiment of the present application also provides an antenna module, which can include a non-terrestrial network antenna for cooperating with an amplification radiator; wherein the amplification radiator and the non-terrestrial network antenna are located on the same plane and on the side of the main radiation direction of the non-terrestrial network antenna, and the distance between the amplification radiator and the non-terrestrial network antenna corresponds to the working frequency band of the non-terrestrial network antenna.

[0089] The non-terrestrial network antenna includes the antenna of a satellite communication network, a unmanned aerial vehicle communication network, a high-altitude platform communication network, and the like, and the amplification radiator can be the amplification radiator of the antenna gain device in the above embodiments. The gain of the non-terrestrial network antenna is affected by itself, including the influence of its working frequency band, so the distance between the amplification radiator and the non-terrestrial network antenna can be determined according to the working frequency band of the non-terrestrial network antenna. As shown in FIGS. 1 and 2, in this embodiment, the non-terrestrial network antenna is taken as a satellite antenna 11 for example; the same or similar contents as the above embodiments can be referred to the above description, and will not be described here.

[0090] In a feasible embodiment, the antenna module can further include an adjacent antenna and a switching module; wherein the adjacent antenna is arranged adjacent to the non-terrestrial network antenna, and the adjacent antenna has a ground arm connected to the metal ground; one end of the switching module is connected to the feed arm of the adjacent antenna, and the other end of the switching module is connected to the metal ground, and the switching module is configured to connect the feed arm and the metal ground in the working frequency band of the non-terrestrial network antenna, so as to short-circuit the adjacent antenna.

[0091] The gain of the non-terrestrial network antenna is affected not only by itself, but also by the state of the adjacent antenna, such as a GPS antenna. The adjacent antenna can be one or more specific antennas, such as a mobile communication main antenna, a WIFI antenna, a near field communication antenna, and the like, and the adjacent antenna is located in the same plane as the non-terrestrial network antenna. In some embodiments, the non-terrestrial network antenna and the adjacent antenna can both be metal frame antennas. The metal ground is a metal shell or other metal component of the terminal device, which can be connected to the ground pin of each component or circuit module of the terminal device to provide a reference potential.

[0092] For example, as shown in FIG. 2, the antenna module 1 includes a satellite antenna 11 and an adjacent antenna. The satellite antenna 11 includes a radiating body 111 and a parasitic branch 114, the radiating body 111 has a ground arm 112 connected to the metal ground 10 and a feed arm 113, forming an IFA (Inverted-F Antenna) + parasitic branch antenna structure, and the adjacent antenna includes a GPS L5 12, and a GPS L1 13 is also arranged adjacent to the side away from the satellite antenna 11 of the GPS L5 12, the GPS L5 12 has a ground arm 121 connected to the metal ground 10 and a feed arm 122, the GPS L1 13 has a ground arm 131 connected to the metal ground 10 and a feed arm 132, and a gap is provided between the feed arm 122 of the GPS L5 12 and the feed arm 132 of the GPS L1 13.

[0093] Since the open circuit or short circuit of the feed arm of the adjacent antenna will affect the gain of the non-terrestrial network antenna, the state of the adjacent antenna can be configured by a switching module, including configuring the adjacent antenna to be in an open circuit state or a short circuit state.

[0094] Referring to FIG. 6, FIG. 6 is another structural schematic diagram of an antenna module provided by an embodiment of the present application; since the state of the GPS L5 12 will affect the gain of the satellite antenna 11, in this embodiment, the antenna module 1 further includes a switching module 14, one end of the switching module 14 is connected to the feed arm 122 of the GPS L5 12, and the other end of the switching module 14 is connected to the metal ground 10, and the working state of the GPS L5 12 can be changed to be short-circuited by the switching module 14, specifically, the feed arm 122 and the metal ground 10 are connected by the switching module 14 within the working frequency band of the non-terrestrial network antenna.

[0095] In this embodiment, the antenna module further includes an adjacent antenna and a switching module, and the feed arm of the adjacent antenna and the metal ground are connected by the switching module within the working frequency band of the non-terrestrial network antenna, so that the adjacent antenna is short-circuited, and the non-terrestrial network antenna and the adjacent antenna are prevented from working at the same time, so as to avoid the working of the adjacent antenna interfering with the working of the non-terrestrial network antenna.

[0096] In one possible implementation, the switching module can include a switch control unit or a band-pass filter unit;

[0097] The switch control unit is connected in parallel with a radio frequency path of the adjacent antenna, one end of the radio frequency path is connected with the feeding arm, and the other end of the radio frequency path is connected with the metal ground, and the switch control unit is configured to be closed in the case that the non-terrestrial network antenna is working, so as to connect the feeding arm with the metal ground;

[0098] One end of the band-pass filter unit is connected with the feeding arm, and the other end of the band-pass filter unit is connected with the metal ground, and the band-pass filter unit is configured to allow the wave of the working frequency band of the non-terrestrial network antenna to pass through, so as to connect the feeding arm with the metal ground.

[0099] In one specific implementation, as shown in FIG. 7, a connection diagram of the switching module is shown, the switching module 14 includes a switch control unit 141, the switch control unit 141 is connected in parallel with a radio frequency path 3, one end of the radio frequency path 3 is connected with the feeding arm of the adjacent antenna, and here is specifically connected with the feeding arm 122 of the GPS L5 12, and the other end of the radio frequency path 3 is connected with the metal ground 10. Among them, the switch control unit 141 is closed in the case that the non-terrestrial network antenna is working, so as to connect the feeding arm 122 with the metal ground 10, at this time, the grounding arm 121 of the GPS L5 12 is also connected with the metal ground 10, so that the GPS L5 12 is short-circuited. Among them, the radio frequency path 3 refers to the internal radio frequency processing circuit, signal receiving circuit or signal transmitting circuit of the terminal device, which is not specifically limited here. The working of the non-terrestrial network antenna can be detected by the switch control unit 141, and when it is detected that the non-terrestrial network antenna is working, the switch can be controlled to be closed to connect the feeding arm 122 with the metal ground 10.

[0100] In another specific implementation, as shown in FIG. 8, another connection diagram of the switching module is shown, the switching module 14 includes a band-pass filter unit 142, one end of the band-pass filter unit 142 is connected with the feeding arm of the adjacent antenna, and here is specifically connected with the feeding arm 122 of the GPS L5 12, and the other end of the band-pass filter unit 142 is connected with the metal ground 10. Among them, the band-pass filter unit 142 allows the wave of the working frequency band of the non-terrestrial network antenna to pass through, so as to connect the feeding arm 122 with the metal ground 10, at this time, the grounding arm 121 of the GPS L5 12 is also connected with the metal ground 10, so that the GPS L5 12 is short-circuited. Among them, the band-pass filter unit 142 can be an LC filter circuit or a band-pass filter, which is not specifically limited here. The band-pass filter unit 142 is set to allow only the wave of the working frequency band of the non-terrestrial network antenna to pass through, and when the non-terrestrial network antenna works in the working frequency band, the band-pass filter unit 142 can connect the feeding arm 122 with the metal ground 10.

[0101] In the embodiment, the switching module is used to switch the feed arm of the adjacent antenna to the metal ground in the working frequency band of the non-ground network antenna, so as to short-circuit the adjacent antenna; the mode current distribution between the non-ground network antenna and the floor can be changed in the working frequency band of the non-ground network antenna, the magnetic field of the main radiation direction of the non-ground network antenna is superimposed in phase, the antenna gain in the direction is improved on the basis of ensuring the directivity of the non-ground network antenna, meanwhile, the performance of the adjacent antenna itself is not affected, so that the effect of further improving the non-ground network communication quality of the terminal equipment can be achieved.

[0102] The above merely provides a specific implementation of the embodiments of the present application, but the protection scope of the present application is not limited thereto, any modification or replacement within the technical range disclosed in the present application can be easily thought by those skilled in the art, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

[0103] Exemplarily, in order to help understand the different effects achieved by the different embodiments of the cooperation between the above-mentioned antenna gain device and the above-mentioned antenna module provided by the embodiments of the present application, several comparative examples and specific examples are listed below for description.

[0104] Comparative Example 1: the antenna module 1 shown in FIG. 2 is used for testing; wherein the feed arm 122 of the GPS L5 12 can actually access the radio frequency channel 3, the GPS L5 12 and the satellite antenna 11 can work at the same time, the front end of the radio frequency channel 3 can be equivalent to 50Ω, a 50Ω resistor is connected to the feed arm 122 of the GPS L5 12 as an equivalent matching resistor, to simulate the GPS L5 12 and the satellite antenna 11 working at the same time, which is recorded as antenna A.

[0105] Comparative Example 2: the antenna module 1 shown in FIG. 6 is used for testing; wherein the feed arm 122 of the GPS L5 12 is connected to the switching module 14, the switching module 14 can switch the GPS L5 12 to short circuit when the satellite antenna 11 works, or switch the GPS L5 12 to short circuit in the working frequency band of the satellite antenna 11, so as to realize that only the satellite antenna 11 works, which is recorded as antenna B.

[0106] As shown in Figure 9 is the S11 curve of the antenna A of the comparative example one and the antenna B of the comparative example two, in which the horizontal axis represents the frequency, unit: GHz, and the vertical axis represents the reflectivity, unit: dB; S11 represents the matching degree of the antenna and the feeder, which is defined as the power ratio of the reflected electromagnetic wave and the incident electromagnetic wave, the greater the absolute value, the higher the matching degree of the antenna and the feeder. Assuming that the working frequency band of the satellite antenna 11, i.e. the communication frequency band of the satellite antenna 11, is TX (transmission): 1.98-2.01 GHz, RX (reception): 2.17-2.20 GHz, first, as can be seen from the figure, the S11 of the antenna A and the antenna B can cover the complete working frequency band of the satellite antenna 11; then, taking 2.2 GHz as the representative of the satellite frequency band for specific analysis: as shown in Figure 10 is the main radiation plane pattern of the antenna A at 2.2 GHz, which shows the main radiation plane pattern corresponding to the cross section of the azimuth plane angle phi = 0 and the cross section of the azimuth plane angle phi = 90, respectively, in combination with the alignment habit of the user when using the terminal device to find the satellite signal, the gain of the satellite antenna 11 in the zenith direction is recorded when the elevation plane angle theta = 0 (marked point 1 in Figure 10), which is about 0.8 dBi.

[0107] As shown in Figure 11 is the main radiation plane pattern of the antenna B at 2.2 GHz, which shows the main radiation plane pattern corresponding to the cross section of the azimuth plane angle phi = 0 and the cross section of the azimuth plane angle phi = 90, respectively, the gain of the satellite antenna 11 in the zenith direction is recorded when the elevation plane angle theta = 0 (marked point 1 in Figure 11), which is about 1.3 dBi.

[0108] As can be seen from the comparison, the gain of the antenna B is improved by 0.5 dBi compared with the gain of the antenna A, because the GPS L5 12 of the antenna B is in a short-circuit state after being connected to the metal ground 10 through the switching module 14, which changes the mode current distribution of the antenna and the floor at 2.2 GHz, so that the far-field zenith direction electric field is in-phase superimposed, slightly improving the antenna gain of the satellite antenna 11 in this direction.

[0109] By connecting the feeding arm of the adjacent antenna to the metal ground through the switching module in the working frequency band of the non-terrestrial network antenna, the adjacent antenna is short-circuited, which can improve the antenna gain in the working frequency band of the non-terrestrial network antenna, ensure the directivity of the non-terrestrial network antenna, and will not affect the performance of the adjacent antenna itself.

[0110] The following continues to take 2.2GHz as a representative C-band to propose specific application examples. First, the corresponding 0.05λ is about 6.8mm, 0.1λ is about 13.6mm, 0.25λ is about 34mm, 0.5λ is about 68mm, and 0.6λ is about 81mm; then it can be determined that the distance d between the amplification radiator 21 and the satellite antenna 11 ranges from 6.8mm≤d≤13.6mm, the length L of the amplification radiator 21 ranges from 34mm≤L≤68mm, and the length L2 of the opposite side radiator 22 ranges from 68mm≤L2≤81mm.

[0113] As shown in FIG. 12, the S11 curve diagram of scheme A is shown, where the horizontal axis represents the frequency in GHz, and the vertical axis represents the reflectivity in dB; taking the C-band of the satellite antenna 11 as 2.2GHz for specific analysis, the main radiation pattern of the satellite antenna 11 at 2.2GHz in scheme A is obtained as shown in FIG. 13, which shows the main radiation pattern corresponding to the cross section of the azimuth plane angle phi=0 and the cross section of the azimuth plane angle phi=90, respectively, and records the gain of the satellite antenna 11 in the zenith direction when the elevation plane angle theta=0 (marked point 1 in FIG. 13), which is about 4.4dBi.

[0114] Example Two: The antenna module 1 and the antenna gain device 2 as shown in FIG. 3, the length L of the amplification radiator 21 is 46mm, denoted as scheme B.

[0115] As shown in FIG. 14, the S11 curve diagram of scheme B is shown, where the horizontal axis represents the frequency in GHz, and the vertical axis represents the reflectivity in dB; taking the C-band of the satellite antenna 11 as 2.2GHz for specific analysis, the main radiation pattern of the satellite antenna 11 at 2.2GHz in scheme B is obtained as shown in FIG. 15, which shows the main radiation pattern corresponding to the cross section of the azimuth plane angle phi=0 and the cross section of the azimuth plane angle phi=90, respectively, and records the gain of the satellite antenna 11 in the zenith direction when the elevation plane angle theta=0 (marked point 1 in FIG. 15), which is about 3.7dBi.

[0116] Example Three: The antenna module 1 and the antenna gain device 2 as shown in FIG. 4, the amplification radiator 21 includes a straight line segment 211 with a length of 46mm and two 5mm bending segments 212 on both sides, denoted as scheme C.

[0117] As shown in Fig. 16 is a S11 curve schematic diagram of scheme C, in which the horizontal axis represents frequency, unit: GHz, the vertical axis represents reflectivity, unit: dB; with satellite antenna 11 Ka band of 2.2 GHz for specific analysis, as shown in Fig. 17 is the main radiation pattern of satellite antenna 11 in scheme C at 2.2 GHz, the figure shows the cross section of the azimuth plane angle phi = 0 and the cross section of the azimuth plane angle phi = 90 corresponding to the main radiation pattern, record the gain of satellite antenna 11 in zenith direction when the elevation angle theta = 0 (point 1 in Fig. 17), about 4.7dBi.

[0118] Example four: as shown in Fig. 5 is the antenna module 1 and antenna gain device 2, the amplification radiator 21 includes a 46 mm straight section 211 and two sides of 5 mm bending section 212, the antenna gain device 2 also includes the length L2 = 70 mm of the opposite side radiator 22, marked as scheme D.

[0119] As shown in Fig. 18 is a S11 curve schematic diagram of scheme D, in which the horizontal axis represents frequency, unit: GHz, the vertical axis represents reflectivity, unit: dB; with satellite antenna 11 Ka band of 2.2 GHz for specific analysis, as shown in Fig. 19 is the main radiation pattern of satellite antenna 11 in scheme D at 2.2 GHz, the figure shows the cross section of the azimuth plane angle phi = 0 and the cross section of the azimuth plane angle phi = 90 corresponding to the main radiation pattern, record the gain of satellite antenna 11 in zenith direction when the elevation angle theta = 0 (point 1 in Fig. 19), about 5.1dBi.

[0120] As can be seen from the above, scheme A in example one has obvious gain improvement compared with antenna A of comparative example one and antenna B of comparative example two, which shows that the scheme of the antenna module and the antenna gain device provided by the embodiment of the application can indeed significantly improve the antenna gain; there is only length difference of the amplification radiator between scheme A in example one and scheme B in example two, but the gain is different, which shows that the improvement of the antenna gain is related to the length of the amplification radiator, and the antenna gain can be adjusted by adjusting the length of the amplification radiator; the length difference of the amplification radiator between scheme C in example three and scheme A in example one is not large, but the amplification radiator of scheme C is provided as a structure of a straight section and two bending sections, and the gain of scheme C is improved compared with the gain of scheme A, which shows that on the basis of ensuring the total length of the amplification radiator, the antenna gain can be further improved by bending the amplification radiator; scheme D in example four increases the opposite side radiator on the basis of scheme C in example three, and the gain of scheme D is obviously improved compared with the gain of scheme C, which shows that the scheme of adding the opposite side radiator can indeed further improve the antenna gain.

[0121] The antenna gain device of the embodiment of the present application cooperates with the antenna module, and specifically, the directional property and gain of the non-ground network antenna in the terminal device can be improved by cooperation of the amplification radiator of the antenna gain device and the non-ground network antenna of the antenna module.
