[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on January 15, 2024, with application number 202410060075.2 and invention name "Mobile Terminal", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of electronic equipment, and in particular to mobile terminals. Background Art

[0004] With the development of human society, mobile devices such as mobile phones have become indispensable tools in people's lives. People's dependence on mobile devices has affected every aspect of their lives. With the rise of mobile terminals using communication satellites, people's demand for practical use of communication satellites for mobile terminals is growing.

[0005] Compared to currently used base stations, communication satellites are fewer in number and farther apart, resulting in relatively low power for radio frequency signals from satellites to the ground. Therefore, to improve the satellite communication performance of mobile terminals, it is necessary to provide mobile terminals with satellite antennas with stronger capabilities.

[0006] The signal beam of a satellite antenna has a certain degree of directionality, and sufficient signal strength is only achieved within a certain beam angle for satellite communication. Conventional mobile terminals include a satellite antenna. To use satellite communication, a switch must be turned on to utilize the antenna for satellite calls. Furthermore, during use, proper alignment is required, requiring the mobile terminal's position to be adjusted. Only when the mobile terminal maintains a certain position can a call be made effectively. Conventional mobile terminals primarily use satellite communication for active calls. Maintaining the mobile terminal in alignment while in standby mode makes it difficult to achieve the desired call function.

[0007] Summary of the Invention

[0008] The mobile terminal provided in the present application includes a satellite antenna system, which has a wide coverage area for receiving radio frequency signals from communication satellites and can realize the function of being called in communication satellite communications.

[0009] In a first aspect, the present application provides a mobile terminal comprising a satellite antenna system for implementing satellite communication functionality for the mobile terminal. Specifically, the satellite antenna system comprises a satellite communication chip and at least two antennas. For ease of description, the at least two antennas are assumed to include a first antenna and a second antenna. The first antenna specifically comprises a first radiator and a first radio frequency module connected thereto. Similarly, the second antenna comprises a second radiator and a second radio frequency module connected thereto. The first antenna and the second antenna are configured to receive radio frequency signals from a communication satellite for downlink communication of the mobile terminal, thereby enabling the mobile terminal to be called. The first and second radio frequency modules are respectively connected to the satellite communication chip, such that the radio frequency signals received by the first radiator are converted by the first radio frequency module and transmitted to the satellite communication chip, and the radio frequency signals received by the second radiator are also converted by the second radio frequency module and transmitted to the satellite communication chip. At least a portion of the first radiator and at least a portion of the second radiator are located on different sides of the mobile terminal, thereby enabling the beam orientations of the first radiator and the second radiator to differ, which helps increase the coverage of the satellite antenna system's high-sensitivity area per angle. Specifically, the weak reception sensitivity area per angle of the first antenna at least partially overlaps with the strong reception sensitivity area per angle of the second antenna, thereby increasing the combined coverage area of ​​the strong reception sensitivity area per angle of the first antenna and the strong reception sensitivity area per angle of the second antenna. This allows the mobile terminal's satellite antenna system to cover a wider range, reduces the difficulty of alignment during use, and enables the mobile terminal to receive radio frequency signals from communication satellites in a variety of postures. This is beneficial for improving the downlink communication effect of the mobile terminal's communication satellite communications, enabling the mobile terminal to have the function of being called in communication satellite communications. In a specific technical solution, the mobile terminal is used to implement at least one of satellite text messaging, satellite phone calls, and satellite Internet access through a satellite communication chip.

[0010] In one technical solution, each of the at least two antennas in a satellite communication system includes a corresponding radiator and a corresponding radio frequency module. The radiator of each antenna is connected to the corresponding radio frequency module, which is in turn connected to a satellite communication chip. Each antenna is used to receive radio frequency signals from a communication satellite, thereby ensuring that the satellite antenna system's high sensitivity zone at each angle has a wide coverage area. If the high sensitivity zone at each angle covers at least 80% of the omnidirectional range, the satellite antenna system can be considered an omnidirectional antenna system. The satellite antenna system has a certain strength within the omnidirectional range of spherical coordinates. A mobile terminal can communicate with the communication satellite without maintaining a specific posture. Specifically, the mobile terminal can receive radio frequency signals from the communication satellite under normal conditions, allowing the mobile terminal to remain in a called state. Normal conditions refer to the mobile terminal not performing additional satellite alignment operations and can be located anywhere in free space, or in a bag or pocket. This solution can enrich the satellite communication scenarios for mobile terminals.

[0011] In one technical solution, the weak reception sensitivity area per angle of one antenna in the satellite antenna system at least partially overlaps with the strong reception sensitivity area per angle of another antenna in the satellite antenna system. This ensures that different areas are substantially covered by the strong reception sensitivity area per angle, making the satellite antenna system an omnidirectional antenna system. In other words, the satellite antenna system of the mobile terminal can receive RF signals from the communication satellite in an omnidirectional manner.

[0012] Specifically, the strong per-angle receive sensitivity zone refers to an area where the per-angle receive sensitivity is less than or equal to a first threshold, and the weak per-angle receive sensitivity zone refers to an area where the per-angle receive sensitivity is greater than the first threshold. Specifically, when detecting the strong per-angle receive sensitivity zone of the antenna, a negative value is detected, i.e., the first threshold is negative. Therefore, the smaller the per-angle receive sensitivity value, the greater the intensity. From the perspective of absolute value, the larger the absolute value of the monitored per-angle receive sensitivity, the greater the intensity.

[0013] The first threshold may be specifically -121 dBm. The strong per-angle receiving sensitivity region refers to a region where the per-angle receiving sensitivity is less than or equal to -121 dBm, and the weak per-angle receiving sensitivity region refers to a region where the per-angle receiving sensitivity is greater than -121 dBm. A setting that meets the above requirements can meet the communication needs of most communication satellites.

[0014] In a further technical solution, at least one antenna in the satellite antenna system is further configured to transmit signals to a communications satellite for uplink communication, thereby enabling a calling function of the satellite antenna system. The satellite antenna system's high-sensitivity area per angle covers at least 80% of the upper hemisphere when the mobile terminal is in use, thereby improving the uplink communication performance of the mobile terminal.

[0015] There is no limit to the number of antennas used to transmit signals to a communications satellite among the at least two antennas in the satellite antenna system. In a specific embodiment, the at least two antennas in the satellite antenna system are also used to transmit signals to a communications satellite. Among the antennas used to transmit signals to a communications satellite, the weak per-angle transmit sensitivity area of ​​one antenna at least partially overlaps with the strong per-angle transmit sensitivity area of ​​another antenna. This improves the coverage of the strong per-angle transmit sensitivity area of ​​the satellite antenna system for a mobile terminal, thereby enhancing call quality for the mobile terminal.

[0016] In one technical solution, the strong per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is greater than or equal to a second threshold, and the weak per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is less than the second threshold. When the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is greater than or equal to the second threshold, the mobile terminal can effectively transmit signals to the communication satellite, thereby enabling communication with the mobile terminal. Conversely, if the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is less than the second threshold, the mobile terminal has difficulty transmitting signals to the communication satellite, thereby hindering communication with the mobile terminal.

[0017] The second threshold may specifically be 25.5 dBm. A high per-angle transmit sensitivity zone refers to an area where the per-angle transmit sensitivity is greater than or equal to 25.5 dBm, while a low per-angle transmit sensitivity zone refers to an area where the per-angle transmit sensitivity is less than 25.5 dBm. A configuration that meets the above requirements can meet the communication needs of most communication satellites.

[0018] In one technical solution, each antenna in the satellite antenna system can be used to transmit signals to communication satellites, thereby improving the satellite communication effect of mobile terminals in different postures and enhancing communication quality.

[0019] To improve the quality of signals transmitted by the antenna to the communication satellite, the RF module of the antenna transmitting signals to the communication satellite includes a power amplifier, which is connected to the satellite communication chip to process the communication signal. In one technical solution, the RF module of each antenna in the above-mentioned satellite antenna system includes a power amplifier.

[0020] In order to reduce the loss in the signal transmission path, the distance between the power amplifier and the connected radiator is closer, thereby shortening the length of the line between the power amplifier and the radiator, reducing link loss and improving signal transmission efficiency.

[0021] In one technical solution, the first RF module includes a first power amplifier, which is connected to a first radiator; the second RF module includes a second power amplifier, which is connected to a second radiator. The distance between the first radiator and the first power amplifier is shorter than the distance between the second radiator and the first power amplifier. This reduces link loss and improves signal transmission efficiency.

[0022] In one technical solution, the power amplifier is a distributed RF terminal. The distance between the mobile terminal's power amplifier and the connected radiator is closer than the distance between the power amplifier and the satellite communication chip. Placing the power amplifier of an antenna closer to the connected radiator helps reduce link loss.

[0023] The satellite communication system also includes a control switch. This control switch is connected to the satellite communication chip and to the radio frequency modules of all antennas. The control switch is used to connect one or more antennas to the satellite communication chip based on the mobile terminal's position, the antenna's transmitted signal strength, and / or the location of the antenna's high-sensitivity area per angle. In short, the active antenna can be selected based on demand, ensuring that one or more antennas connected to the satellite communication chip in the mobile terminal's satellite communication system are in an active state for signal transmission.

[0024] In a specific technical solution, the mobile terminal includes a metal frame, a portion of which forms the antenna's radiator. This metal frame can be the mobile terminal's midframe. In this embodiment, the antenna's radiator and the mobile terminal's midframe can be reused, reducing the space occupied by the antenna's radiator and improving the mobile terminal's integration. Furthermore, the antenna's radiator is less obstructed, which helps improve the antenna's communication performance.

[0025] In a specific technical solution, when the satellite antenna system includes two antennas, a first radiator and a second radiator of the satellite antenna system are located on opposite sides of the mobile terminal. This facilitates the mutual complementation of the first and second antennas, resulting in a wider coverage area for the mobile terminal's satellite antenna system, improving downlink communication performance of satellite communications for the mobile terminal, and enabling the mobile terminal to receive calls via satellite communications.

[0026] In a specific technical solution, the satellite antenna system includes three antennas: a first antenna, a second antenna, and a third antenna. The third antenna includes a connected third radiator and a third radio frequency module, which is also connected to the satellite communication chip. The first, second, and third radiators are positioned on three different sides of the mobile terminal. This ensures that the downward radiation patterns of the three antennas complement each other, providing the mobile terminal with a wider coverage area of ​​the satellite antenna system and enabling the mobile terminal to receive calls via satellite communications.

[0027] In a specific technical solution, the satellite antenna system includes four antennas: a first antenna, a second antenna, a third antenna, and a fourth antenna. The third antenna includes a third radiator and a third radio frequency module connected to each other, and the fourth antenna includes a fourth radiator and a fourth radio frequency module connected to each other. The third radio frequency module and the fourth radio frequency module are also respectively connected to the satellite communication chip. The first radiator, the second radiator, the third radiator, and the fourth radiator are respectively arranged on four different sides of the mobile terminal. The downlink radiation patterns of the four antennas complement each other, so that the satellite antenna system of the mobile terminal has a wider coverage range, reducing the difficulty of satellite alignment during use, and the mobile terminal can receive radio frequency signals from the communication satellite in a variety of postures. This is conducive to improving the downlink communication effect of the mobile terminal's communication satellite communication, allowing the mobile terminal to have the function of being called by the communication satellite communication.

[0028] In a second aspect, the present application also provides a mobile terminal comprising a satellite antenna system for implementing satellite communication functions of the mobile terminal. Specifically, the satellite antenna system comprises a satellite communication chip and at least two antennas. At least one antenna in the satellite antenna system is used to transmit signals to a communication satellite for implementing the calling function of the mobile terminal. The satellite antenna system has a high sensitivity area for each angle of transmission that covers at least 80% of the upper hemisphere when the mobile terminal is in use. This allows the satellite antenna system of the mobile terminal to cover a wider range, reducing the difficulty of satellite alignment during use, and the mobile terminal can transmit radio frequency signals to the communication satellite in a variety of postures. This is beneficial for improving the uplink communication effect of the mobile terminal's communication satellite communication, enabling the mobile terminal to have the function of being called by the communication satellite communication. In a specific technical solution, the mobile terminal is used to implement at least one of satellite text messaging, satellite phone calls, and satellite Internet access through the satellite communication chip.

[0029] There is no limit to the number of antennas used to transmit signals to a communications satellite among the at least two antennas in the satellite antenna system. In a specific embodiment, the at least two antennas in the satellite antenna system are also used to transmit signals to a communications satellite. Among the antennas used to transmit signals to a communications satellite, the weak per-angle transmit sensitivity area of ​​one antenna at least partially overlaps with the strong per-angle transmit sensitivity area of ​​another antenna. This improves the coverage of the strong per-angle transmit sensitivity area of ​​the satellite antenna system for a mobile terminal, thereby enhancing call quality for the mobile terminal.

[0030] In one technical solution, the strong per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is greater than or equal to a second threshold, and the weak per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is less than the second threshold. When the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is greater than or equal to the second threshold, the mobile terminal can effectively transmit signals to the communication satellite, thereby enabling communication with the mobile terminal. Conversely, if the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is less than the second threshold, the mobile terminal has difficulty transmitting signals to the communication satellite, thereby hindering communication with the mobile terminal.

[0031] The second threshold may specifically be 25.5 dBm. A high per-angle transmit sensitivity zone refers to an area where the per-angle transmit sensitivity is greater than or equal to 25.5 dBm, while a low per-angle transmit sensitivity zone refers to an area where the per-angle transmit sensitivity is less than 25.5 dBm. A configuration that meets the above requirements can meet the communication needs of most communication satellites.

[0032] In one technical solution, each antenna in the satellite antenna system can be used to transmit signals to communication satellites, thereby improving the satellite communication effect of mobile terminals in different postures and enhancing communication quality.

[0033] To improve the quality of signals transmitted by the antenna to the communication satellite, the RF module of the antenna transmitting signals to the communication satellite includes a power amplifier, which is connected to the satellite communication chip to process the communication signal. In one technical solution, the RF module of each antenna in the above-mentioned satellite antenna system includes a power amplifier.

[0034] In order to reduce the loss in the signal transmission path, the distance between the power amplifier and the connected radiator is closer, thereby shortening the length of the line between the power amplifier and the radiator, reducing link loss and improving signal transmission efficiency.

[0035] In one technical solution, the first RF module includes a first power amplifier, which is connected to a first radiator; the second RF module includes a second power amplifier, which is connected to a second radiator. The distance between the first radiator and the first power amplifier is shorter than the distance between the second radiator and the first power amplifier. This reduces link loss and improves signal transmission efficiency.

[0036] In one technical solution, the power amplifier is a distributed RF terminal. The distance between the mobile terminal's power amplifier and the connected radiator is closer than the distance between the power amplifier and the satellite communication chip. Placing the power amplifier of an antenna closer to the connected radiator helps reduce link loss.

[0037] The satellite communication system also includes a control switch. This control switch is connected to the satellite communication chip and to the radio frequency modules of all antennas. The control switch is used to connect one or more antennas to the satellite communication chip based on the mobile terminal's position, the antenna's transmitted signal strength, and / or the location of the antenna's high-sensitivity area per angle. In short, the active antenna can be selected based on demand, ensuring that one or more antennas connected to the satellite communication chip in the mobile terminal's satellite communication system are in an active state for signal transmission.

[0038] In a specific technical solution, the mobile terminal includes a metal frame, a portion of which forms the antenna's radiator. This metal frame can be the mobile terminal's midframe. In this embodiment, the antenna's radiator and the mobile terminal's midframe can be reused, reducing the space occupied by the antenna's radiator and improving the mobile terminal's integration. Furthermore, the antenna's radiator is less obstructed, which helps improve the antenna's communication performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0063] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a", "an", "said", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0064] References in this specification to "one embodiment" or "a specific embodiment" mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. The terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically stated.

[0065] In order to facilitate understanding of the mobile terminal provided in the embodiment of the present application, its application scenario is first introduced below.

[0066] FIG1 is a schematic diagram of satellite communication performed by a mobile terminal in an embodiment of the present application. As shown in FIG1 , communication satellite communication belongs to non-terrestrial network (NTN) communication and can be used to communicate with a mobile terminal. Compared with terrestrial communication, communication satellite communication can provide a wider coverage area. In particular, for areas where there are few cellular communication base stations or they are difficult to cover, communication satellites can be used for communication. Satellite communication systems can be divided into the following three types according to the orbital altitude of the satellite: geostationary Earth Orbit (GEO) satellite communication system (also known as synchronous orbit communication satellite), medium Earth Orbit (MEO) satellite communication system and low Earth Orbit (LEO) satellite communication system. The orbital altitude of GEO satellites is 35,786 km. Its main advantage is that it can remain stationary relative to the ground and provide a large coverage area. The orbital altitude of MEO satellites is between 2,000 and 35,786 km. The advantage is that global coverage can be achieved with a relatively small number of satellites. Considering the advantages and disadvantages of MEO satellite communication, MEO satellites are currently mainly used for positioning and navigation. The orbital altitude of LEO satellites ranges from 300 to 2000 km. LEO satellites have lower orbital altitudes than MEO and GEO satellites, and have the advantages of small data transmission delay, small transmission loss, and relatively low launch cost.

[0067] To utilize satellite communications, mobile terminals are equipped with satellite antennas. However, the signal beam of a satellite antenna has a certain degree of directionality. Conventional mobile terminals that include a satellite antenna require a switch to be turned on to use the antenna for satellite calls. Furthermore, during use, the satellite antenna must be aligned, requiring the mobile terminal's position to be adjusted. Only when the mobile terminal maintains a certain position can a call be made effectively. Furthermore, conventional mobile terminals primarily use satellite communications for active calls. Maintaining the mobile terminal in alignment while in standby mode makes it difficult to achieve the desired call function.

[0068] To this end, the present application provides a mobile terminal comprising at least two satellite antennas for realizing a called function of the mobile terminal using a communication satellite.

[0069] FIG2 is a schematic structural diagram of an electronic device in an embodiment of the present application. As shown in FIG2 , taking a mobile phone as an example, electronic device 010 may include: a cover 013, a display / module 015, a printed circuit board (PCB) 017, a middle frame 019, and a rear cover 021. It should be understood that in some embodiments, cover 013 may be a glass cover, or may be replaced with a cover made of other materials, such as an ultra-thin glass cover, a PET (Polyethylene terephthalate) cover, etc.

[0070] The cover plate 013 can be placed close to the display screen 015 , mainly to protect and prevent dust from the display screen 015 .

[0071] In one embodiment, the display screen 015 may include a liquid crystal display panel (LCD), a light emitting diode (LED) display panel, or an organic light-emitting semiconductor (OLED) display panel, etc., which is not limited in this application.

[0072] The middle frame 019 mainly plays a supporting role for the whole machine. FIG2 shows that PCB017 is arranged between the middle frame 019 and the back cover 021. It should be understood that in one embodiment, PCB017 can also be arranged between the middle frame 019 and the display screen 015. This application does not limit this. Among them, the printed circuit board PCB017 can adopt a flame-resistant material (FR-4) dielectric board, a Rogers dielectric board, a mixed dielectric board of Rogers and FR-4, and so on. Here, FR-4 is a code for a grade of flame-resistant material, and the Rogers dielectric board is a high-frequency board. PCB017 carries electronic components, such as radio frequency chips.

[0073] The electronic device 010 may also include a battery (not shown). The battery may be disposed between the middle frame 019 and the back cover 021, or between the middle frame 019 and the display screen 015, although this application does not limit this. In some embodiments, the PCB 017 is divided into a main board and a sub-board, and the battery may be disposed between the main board and the sub-board. The main board may be disposed between the middle frame 019 and the upper edge of the battery, and the sub-board may be disposed between the middle frame 019 and the lower edge of the battery.

[0074] The electronic device 010 may further include a frame 011, which may be formed of a conductive material such as metal. The frame 011 may be disposed between the display screen 015 and the back cover 021 and extend circumferentially around the periphery of the electronic device 010. The frame 011 may have four sides surrounding the display screen 015 to help secure the display screen 015. In one implementation, the frame 011 made of a metal material may be directly used as the metal frame of the electronic device 010, forming the appearance of a metal frame, which is suitable for metal industrial design (ID). In another implementation, the outer surface of the frame 011 may also be a non-metallic material, such as a plastic frame, forming the appearance of a non-metallic frame, which is suitable for non-metallic ID.

[0075] The middle frame 019 may include a border 011, and the middle frame 019 including the border 011 is an integral part that can support the electronic devices in the whole machine. The cover 013 and the back cover 021 are respectively covered along the upper and lower edges of the border to form the outer shell or shell (housing) of the electronic device. Alternatively, the border 011 may not be regarded as part of the middle frame 019. In one embodiment, the border 011 can be connected to the middle frame 019 and formed as one piece. In another embodiment, the border 011 may include a protrusion extending inward to be connected to the middle frame 019, for example, by means of shrapnel, screws, welding, etc. In one embodiment, the cover 013, the back cover 021, the border 011 and the middle frame 019 can be collectively referred to as the outer shell or shell of the electronic device 010. It should be understood that "shell or casing" can be used to refer to part or all of any one of the cover plate 013, the back cover 021, the frame 011 or the middle frame 019, or to refer to part or all of any combination of the cover plate 013, the back cover 021, the frame 011 or the middle frame 019.

[0076] The back cover 021 can be a back cover made of metal material; it can also be a back cover made of non-conductive material, such as a glass back cover, a plastic back cover or other non-metallic back cover; it can also be a back cover made of both conductive and non-conductive materials.

[0077] In one embodiment, the back cover 021 including conductive material can replace the middle frame 019 and be integrated with the frame 011 to support the electronic devices in the entire device.

[0078] In one embodiment, the conductive parts in the middle frame 019 and / or the back cover 021 can serve as a reference ground for the electronic device 010 , wherein the frame 011 and PCB 017 of the electronic device can be grounded by being electrically connected to the middle frame 019 .

[0079] In one embodiment, the bezel 011 can at least partially serve as an antenna radiator to transmit and receive radio frequency signals. A gap can exist between this portion of the bezel serving as the radiator and other portions of the middle frame 019, or between the bezel and the middle frame 019, to ensure a good radiation environment for the antenna radiator. In one embodiment, an aperture can be provided near this portion of the bezel serving as the antenna radiator. In one embodiment, the aperture can include an aperture provided within the interior of the electronic device 010, for example, an aperture that is not visible from the exterior of the electronic device 010. In one embodiment, the internal aperture can be formed by any one of the middle frame, battery, circuit board, back cover, display, or other internal conductive components, or by a combination of multiple components. For example, the internal aperture can be formed by a structural member of the middle frame. In one embodiment, the aperture can also include a slit / opening / opening provided in the bezel 011. In one embodiment, the slit / opening / opening in the bezel 011 can be a gap formed in the bezel, dividing the bezel 011 into two unconnected portions at this gap. In one embodiment, the aperture can also include a slit / opening / opening provided in the back cover 021 or display 015. In one embodiment, the back cover 021 includes a conductive material, and the apertures provided in the conductive material may be connected to the slits or gaps in the frame to form a continuous aperture on the exterior surface of the electronic device 010 .

[0080] In one embodiment, the frame 011 includes an inwardly extending protrusion for connecting to other portions of the middle frame 019 or to the middle frame 019 (in one embodiment, the protrusion may be integrally formed). In one embodiment, the protrusion includes a conductive material and may also be used to receive a feed signal or connect to a floor, allowing the corresponding frame portion to receive / transmit radio frequency signals.

[0081] In one embodiment, the antenna of the electronic device 010 can also be arranged in the frame 011. The frame 011 includes a non-conductive material, and the antenna radiator can be located in the electronic device 010 and arranged along the frame 011, or the antenna radiator can be at least partially embedded in the non-conductive material of the frame. In one embodiment, the antenna radiator is arranged close to the non-conductive material of the frame 011 to minimize the volume occupied by the antenna radiator and be closer to the outside of the electronic device 010 to achieve better signal transmission effect. It should be noted that the antenna radiator is arranged close to the frame 011, which means that the antenna radiator can be arranged close to the frame 011, or it can be arranged close to the frame 011, for example, there can be a certain small gap between the antenna radiator and the frame 011.

[0082] In one embodiment, the antenna of electronic device 010 may also be disposed within the housing, such as a bracket antenna (not shown in FIG. 2 ). A gap may exist between the antenna disposed within the housing and other conductive components within the housing to ensure a good radiation environment for the antenna radiator. In one embodiment, an aperture may be disposed near the antenna radiator.

In one embodiment, the internal aperture may be formed by any one of the bezel, midframe, battery, circuit board, back cover, display, or other internal conductive components, or by a combination of multiple components. For example, the internal aperture may be formed by a structural member of the midframe. In one embodiment, the aperture may also include a slit / opening / opening disposed on bezel 011. In one embodiment, the slit / opening / opening on bezel 011 may be a break formed in the bezel, dividing bezel 011 into two parts that are not directly connected at the break.

[0083] FIG. 2 only schematically illustrates some components of the electronic device 010 , and the actual shapes, sizes, and structures of these components are not limited by FIG. 2 .

[0084] It should be understood that in the embodiments of the present application, the surface where the display screen of the electronic device is located can be considered as the front surface, the surface where the back cover is located can be considered as the back surface, and the surface where the frame is located can be considered as the side surface.

[0085] It should be understood that in the embodiments of the present application, it is considered that when a user holds the electronic device (usually vertically and facing the screen), the orientation of the electronic device has a top, a bottom, and a side.

[0086] The mobile terminal in the embodiment of the present application can specifically have a variety of options, for example, it can include any mobile terminal such as a straight-screen phone, a folding phone, a multi-fold phone form factor, a tablet computer or a smart screen.

[0087] FIG3 is a schematic diagram of the structure of a mobile terminal according to an embodiment of the present application. As shown in FIG3 , the mobile terminal according to an embodiment of the present application includes a satellite antenna system, which is used to receive and transmit electromagnetic waves. Specifically, the satellite antenna system is used to receive electromagnetic waves from a communication satellite or to transmit electromagnetic waves to a communication satellite. The satellite antenna system is used to transmit electromagnetic waves to and from the communication satellite, thereby enabling the satellite communication function of the mobile terminal.

[0088] As shown in Figure 3, in one embodiment, the satellite antenna system includes a satellite communication chip 11 and at least two antennas 12. The antennas 12 include a radiator 121 and a radio frequency module 122. The radiator 121 is connected to the radio frequency module 122, which is then connected to the satellite communication chip 11, thereby enabling satellite communications using the satellite antenna system. In a specific embodiment, the mobile terminal is used to implement at least one of satellite text messaging, satellite phone calls, and satellite internet access via the satellite communication chip 11.

[0089] In one embodiment, the at least two antennas 12 include a first antenna 12a and a second antenna 12b. The first antenna 12a includes a first radiator 121a and a first radio frequency module 122a connected together, and the second antenna 12b includes a second radiator 121b and a second radio frequency module 122b connected together. The first antenna 12a and the second antenna 12b are configured to receive radio frequency signals from a communication satellite. The first radio frequency module 122a and the second radio frequency module 122b are respectively connected to the satellite communication chip 11, so that the first antenna 12a and the second antenna 12b work in conjunction to implement satellite communication functions for the mobile terminal. At least a portion of the first radiator 121a and at least a portion of the second radiator 121b are located on different sides of the mobile terminal, so that the beam direction of the first radiator 121a differs from the beam direction of the second radiator 121b, thereby increasing the coverage range of the entire satellite antenna system of the mobile terminal.

[0090] Figure 4 illustrates the downlink directional pattern of the satellite antenna system for the mobile terminal in the embodiment shown in Figure 3 . The solid line represents the directional pattern of the first antenna 12a receiving RF signals from the communication satellite, and the dotted line represents the directional pattern of the second antenna 12b receiving RF signals from the communication satellite. As shown in Figure 4 , both the first antenna 12a and the second antenna 12b are configured to receive RF signals from the communication satellite. The weak effective isotropic sensitivity (EIS) per angle of the first antenna 12a at least partially overlaps with the strong EIS per angle of the second antenna 12b. As can be appreciated, the directional patterns of the first antenna 12a and the second antenna 12b are complementary to each other. Consequently, the combined coverage area of ​​the strong EIS per angle of the first antenna 12a and the strong EIS per angle of the second antenna 12b is relatively large, extending the coverage area of ​​the mobile terminal's satellite antenna system. This reduces the difficulty of satellite alignment during use, allowing the mobile terminal to receive RF signals from the communication satellite in a wide range of postures. This improves the downlink performance of the mobile terminal's communication satellite communications, enabling the mobile terminal to receive calls in communication satellite communications.

[0091] In one embodiment, each of the at least two antennas 12 of the mobile terminal includes a corresponding radiator 121 and a corresponding radio frequency module 122. The radiator 121 of each antenna 12 is connected to the corresponding radio frequency module 122, and the corresponding radio frequency module 122 is connected to the satellite communication chip 11. Each antenna 12 is used to receive signals radiated by a communication satellite. If the satellite antenna system's strong receiving sensitivity area per angle covers at least 80% of the omnidirectional area, the satellite antenna system can be considered an omnidirectional antenna system. In a specific embodiment, the strong receiving sensitivity area per angle of the satellite antenna system covering at least 80% of the omnidirectional area refers to discrete value coverage, that is, when testing the satellite antenna system's receiving sensitivity per angle, discrete values ​​are detected. The omnidirectional antenna system means that the mobile terminal's strong EIS area in free space covers at least 80% of the omnidirectional area. Omnidirectional refers to the elevation angle range of 0° to 180° and the azimuth angle range of 0° to 360° in spherical coordinates. The strong EIS area specifically refers to the area where the antenna can receive communication satellite signals.

[0092] The strong receiving sensitivity area at each angle of the above-mentioned satellite antenna system can be continuous or discontinuous, as long as the sum of the strong receiving sensitivity areas at each angle covers at least 80% of the omnidirectional direction.

[0093] In this embodiment, the mobile terminal's satellite antenna system is an omnidirectional antenna system. Specifically, the satellite antenna system has a certain strength within the omnidirectional range of spherical coordinates. Therefore, the mobile terminal can communicate with the communication satellite without maintaining a specific posture. Specifically, the mobile terminal can receive the communication satellite's radio frequency signal under normal conditions, allowing the mobile terminal to remain in a called state. This normal state refers to the mobile terminal not performing additional satellite alignment operations and can be located anywhere in free space, or in a bag or pocket. This solution can enrich the satellite communication scenarios of mobile terminals.

[0094] In a specific embodiment, the number of antennas 12 included in the satellite antenna system is not limited, and may include two, three, or more antennas 12. The weak reception sensitivity area per angle of one antenna 12 in the satellite antenna system at least partially overlaps with the strong reception sensitivity area per angle of another antenna 12 in the satellite antenna system. In this embodiment, at least a portion of the weak reception sensitivity area per angle of one antenna 12 in the satellite antenna system is covered by the strong reception sensitivity area per angle of another antenna 12, thereby making the satellite antenna system an omnidirectional antenna system. In other words, the satellite antenna system of the mobile terminal can receive radio frequency signals from the communication satellite in an omnidirectional manner.

[0095] The aforementioned high per-angle reception sensitivity region refers to an area where the per-angle reception sensitivity is less than or equal to a first threshold, and the low per-angle reception sensitivity region refers to an area where the per-angle reception sensitivity is greater than the first threshold. When the per-angle reception sensitivity of the satellite antenna system of the mobile terminal is less than or equal to the first threshold, the mobile terminal can effectively receive the RF signal from the communication satellite, enabling communication with the mobile terminal. Conversely, if the per-angle reception sensitivity of the satellite antenna system of the mobile terminal is greater than the first threshold, the mobile terminal may have difficulty receiving the RF signal from the communication satellite, or the quality of the received RF signal from the communication satellite may be poor, making communication with the mobile terminal difficult.

[0096] In one embodiment, the first threshold is -121dBm. A strong per-angle receiving sensitivity region refers to a region where the per-angle receiving sensitivity is less than or equal to -121dBm, such as -123dBm, -125dBm, -130dBm, -145dBm, or -150dBm. A weak per-angle receiving sensitivity region refers to a region where the per-angle receiving sensitivity is greater than -121dBm, such as -120dBm, -115dBm, -110dBm, -105dBm, or -100dBm. In a specific embodiment, when the communication satellite is a Tiantong communication satellite or a Xingwang communication satellite, the first threshold is -121dBm. When the communication satellite is a Beidou communication satellite, the first threshold is -123.5dBm.

[0097] In a further embodiment, the mobile terminal is further configured to transmit signals to a communication satellite, and at least one antenna 12 in the satellite antenna system is further configured to transmit signals to the communication satellite. That is, the satellite antenna system may have only one antenna 12 configured to transmit signals to a communication satellite, or may have two or more antennas 12 configured to transmit signals to a communication satellite; alternatively, each antenna 12 in the satellite antenna system may be configured to transmit signals to a communication satellite.

[0098] FIG5 illustrates an uplink pattern of the satellite antenna system of the mobile terminal in the embodiment shown in FIG3 . In the embodiment shown in FIG5 , the first antenna 12a is used to transmit signals to a communication satellite. As shown in FIG5 , the satellite antenna system's effective isotropic radiated power (ERIP) per angle strong region covers at least 80% of the upper hemisphere of the mobile terminal when in use. The upper hemisphere refers to the elevation angle range of 0° to 90° and the azimuth angle range of 0° to 360° in spherical coordinates. The upper hemisphere refers to the upper hemisphere of the mobile terminal in its current position. For example, when the mobile terminal is in a handheld position (e.g., when using a handheld mobile terminal for a call), the upper hemisphere of the mobile terminal refers to the hemisphere at the top of the mobile terminal. When the mobile terminal is in a free position (e.g., when using a Bluetooth headset for a call, or when the mobile terminal is in a pocket, on a desk, or in a bag), the upper hemisphere of the mobile terminal refers to the hemisphere at the top of the mobile terminal, which may be the hemisphere at the side of the mobile terminal or the display screen.

[0099] Among the at least two antennas of the satellite antenna system of the mobile terminal provided in the present application, there is no limit on the number of antennas used to transmit signals to the communication satellite.

[0100] In one embodiment, an antenna 12 in the satellite antenna system is used to transmit signals to a communication satellite. The antenna 12 is a wide-beam antenna that can achieve a high sensitivity area at each transmission angle covering at least 80% of the upper hemisphere of the mobile terminal.

[0101] In one embodiment, at least two antennas 12 in the satellite antenna system are also used to transmit signals to a communications satellite. Among the antennas 12 used to transmit signals to the communications satellite, the weak per-angle transmit sensitivity area of ​​one antenna 12 at least partially overlaps with the strong per-angle transmit sensitivity area of ​​another antenna 12. In this embodiment, the weak per-angle transmit sensitivity area of ​​one antenna 12 in the satellite antenna system used to transmit signals to the communications satellite is at least partially covered by the strong per-angle transmit sensitivity area of ​​another antenna 12, thereby improving the coverage of the strong per-angle transmit sensitivity area of ​​the satellite antenna system for a mobile terminal and enhancing the call quality of the mobile terminal.

[0102] The aforementioned high per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is greater than or equal to the second threshold, and the low per-angle transmit sensitivity region refers to a region where the per-angle transmit sensitivity is less than the second threshold. When the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is greater than or equal to the second threshold, the mobile terminal can effectively transmit signals to the communication satellite, thereby enabling communication with the mobile terminal. Conversely, if the per-angle transmit sensitivity of the satellite antenna system of the mobile terminal is less than the second threshold, the mobile terminal has difficulty transmitting signals to the communication satellite, thereby hindering communication with the mobile terminal.

[0103] In one embodiment, the second threshold is 25.5dBm. A high per-angle transmit sensitivity zone refers to an area with a per-angle transmit sensitivity greater than or equal to 25.5dBm, and a low per-angle transmit sensitivity zone refers to an area with a per-angle transmit sensitivity less than 25.5dBm. In a specific embodiment, when the communication satellite is a Tiantong communication satellite, the second threshold is 27dBm; when the communication satellite is a Xingwang communication satellite, the second threshold is 26dBm. When the communication satellite is a Beidou communication satellite, the second threshold is 25.5dBm.

[0104] The RF module 122 of the antenna 12 in the satellite antenna system, which transmits signals to a communications satellite, includes a power amplifier (PA) for processing the signals transmitted to the communications satellite. In one embodiment, the RF module 122 of each antenna 12 in the satellite antenna system includes a power amplifier connected to the satellite communications chip 11, enabling each antenna 12 in the satellite antenna system to transmit signals to the communications satellite, thereby improving the call quality of the mobile terminal.

[0105] In one embodiment, both the first antenna 12a and the second antenna 12b are used to transmit signals to a communications satellite. The first RF module 122a of the first antenna 12a includes a first power amplifier, and the second RF module 122b of the second antenna 12b includes a second power amplifier. The first and second power amplifiers are respectively connected to the satellite communications chip 11. The distance between the first radiator 121a and the first power amplifier is shorter than the distance between the second radiator 121b and the first power amplifier. In a specific embodiment, the distance between the second radiator 121b and the second power amplifier is shorter than the distance between the first radiator 121a and the second power amplifier. The distance between the power amplifier and the connected radiator 121 is shorter than the distance between the power amplifier and other radiators 121. The closer distance between the power amplifier and the connected radiator 121 shortens the line connecting the power amplifier and the radiator 121, reducing plate transmission loss, link loss, and improving signal transmission efficiency.

[0106] In one embodiment, the power amplifier is a distributed radio frequency terminal. In one embodiment, the distance between the mobile terminal's power amplifier and the connected radiator 121 is shorter than the distance between the power amplifier and the satellite communication chip 11. Placing the power amplifier of an antenna 12 closer to the connected radiator 121 helps reduce link loss.

[0107] In a specific embodiment, the distance between the power amplifier of the antenna 12 and the connected radiator 121 is less than or equal to 20 mm. Therefore, the distance between the power amplifier of the antenna 12 and the radiator 121 is also relatively short.

[0108] Figure 6 is a structural diagram of a mobile terminal in an embodiment of the present application. As shown in Figure 6, the mobile terminal further includes a control switch 2, which is connected to the satellite communication chip 11, and the control switch 2 is connected to the radio frequency modules 122 of all antennas 12. It can be understood that the control switch 2 is connected between the radio frequency module 122 of the antenna 12 and the satellite communication chip 11, and is used to control the connection relationship between the antenna 12 and the satellite communication chip 11, and then select the antenna 12 used for communication. Specifically, the control switch 2 is used to connect one or more antennas 12 and the satellite communication chip 11 according to the posture of the mobile terminal and / or the position of the strong transmission sensitivity area of ​​each angle of the antenna 12. It can be understood that the one or more antennas 12 connected to the satellite communication chip 11 are in working state for transmitting signals.

[0109] In a specific embodiment, the control switch 2 can select the working antenna 12 according to the posture of the mobile terminal. For example, when the mobile terminal is held in a handheld position for a call, the mobile terminal is approximately in a vertical position. The control switch 2 connects the radiator 121 to the RF module 122 of the antenna 12 located at the top of the mobile terminal, which is connected to the satellite communication chip 11. The beam of the radiator 121 located at the top of the mobile terminal is facing upward, which has a better signal transmission effect with the communication satellite. In addition, the user can also use Bluetooth or speakerphone to make calls. In this scenario, the posture of the mobile terminal may have multiple options. The control switch 2 can connect one or more antennas 12 facing upward in the specific posture of the mobile terminal to be in an operating state to improve the communication effect of the mobile terminal.

[0110] In one embodiment, the mobile terminal includes an accelerometer-sensor (G-sensor), which can be used to monitor the posture of the mobile terminal.

[0111] In one embodiment, the control switch 2 can connect one or more antennas 12 to an operational state based on the location of the antenna 12's high angular transmission sensitivity area. Specifically, the control switch 2 can select one or more antennas 12 to be connected to an operational state based on the relationship between the location of the communication satellite and the location of the antenna 12's high angular transmission sensitivity area. Specifically, the control switch 2 connects one or more antennas 12 to an operational state based on the relationship between the location of the communication satellite and the location of the antenna 12's high angular transmission sensitivity area. Specifically, the control switch 2 connects the antenna 12 whose high angular transmission sensitivity area faces the communication satellite to an operational state.

[0112] In one embodiment, the control switch 2 may also be operated based on a comparison of the transmission signal strengths of different antennas 12 , and select one or more antennas 12 with stronger transmission signal strengths to be in an operating state.

[0113] In addition to selecting the antenna 12 for uplink communication, the control switch 2 can also be used to select the antenna 12 for downlink communication. In one embodiment, the control switch 2 of the mobile terminal selects one or more antennas 12 with higher received signal strength to be in operation based on the comparison of received signal strengths of different antennas 12.

[0114] In one embodiment, the antennas 12 for downlink communication can operate simultaneously to improve the ability of the mobile terminal to receive signals.

[0115] In an embodiment of the present application, the frame of the mobile terminal is a metal frame. For example, the metal frame can be the middle frame of the mobile terminal. Part of the structure of the above-mentioned metal frame forms the radiator 121 of the antenna 12. In this embodiment, the radiator 121 of the antenna 12 and the middle frame of the mobile terminal can be reused, reducing the space occupied by the radiator 121 of the antenna 12 and improving the integration of the mobile terminal. In addition, the radiator 121 of the antenna 12 is less obstructed, which is conducive to improving the communication effect of the antenna 12.

[0116] In the embodiments of the present application, the number of antennas 12 included in the satellite antenna system of the mobile terminal is not limited, and several specific embodiments are listed below.

[0117] As shown in Figures 3 and 6, in one embodiment, the satellite antenna system includes two antennas 12, namely the first antenna 12a and the second antenna 12b. The first radiator 121a and the second radiator 121b of the satellite antenna system are located on opposite sides of the mobile terminal. Both the first antenna 12a and the second antenna 12b are used to receive radio frequency signals from a communication satellite, and at least one of the first antenna 12a and the second antenna 12b is used to transmit signals to the communication satellite.

[0118] In one embodiment, as shown in FIG6 , both the first antenna 12a and the second antenna 12b are used to receive radio frequency signals from a communication satellite, and both the first antenna 12a and the second antenna 12b are used to transmit signals to the communication satellite. To achieve these functions, the first radio frequency module 122a of the first antenna 12a includes a power amplifier and a low-noise amplifier (LNA), and the second radio frequency module 122b of the second antenna 12b also includes a power amplifier and a low-noise amplifier.

[0119] In the embodiment shown in FIG3 and FIG6 , the first radiator 121a of the first antenna 12a is disposed on the side of the top of the mobile terminal, and the second radiator 121b of the second antenna 12b is disposed on the side of the bottom of the mobile terminal.

[0120] The downlink directional pattern of the satellite antenna system for a mobile terminal including two antennas 12 can be seen in Figure 4 . The directional pattern of the first antenna 12a and the directional pattern of the second antenna 12b are complementary to each other. As a result, the combined coverage area of ​​the strong reception sensitivity zone per angle of the first antenna 12a and the strong reception sensitivity zone per angle of the second antenna 12b is relatively large, resulting in a wide coverage area for the mobile terminal's satellite antenna system. The satellite antenna system is an omnidirectional antenna system. This reduces the difficulty of satellite alignment during use, allowing the mobile terminal to receive RF signals from communication satellites in a wide range of postures. This improves the downlink communication performance of the mobile terminal's communication satellite communications, enabling the mobile terminal to receive calls in communication satellite communications.

[0121] In a specific embodiment, the strong area of ​​the EIS of the first antenna 12a at least covers the pitch angle of 0° to 90° and the azimuth angle of 0° to 360° in spherical coordinates; the strong area of ​​the EIS of the second antenna 12b at least covers the pitch angle of 90° to 180° and the azimuth angle of 0° to 360° in spherical coordinates. In one embodiment, the strong area of ​​the EIS of the first antenna 12a at least covers the pitch angle of 0° to 80° and the azimuth angle of 0° to 360° in spherical coordinates; the strong area of ​​the EIS of the second antenna 12b at least covers the pitch angle of 100° to 180° and the azimuth angle of 0° to 360° in spherical coordinates.

[0122] FIG7 is a schematic diagram of a structure of a mobile terminal according to an embodiment of the present application. As shown in FIG7 , in one embodiment, the satellite antenna system of the mobile terminal according to the present application includes three antennas 12. Specifically, the satellite antenna system includes the first antenna 12a, the second antenna 12b, and the third antenna 12c. The third antenna 12c includes a third radiator 121c and a third radio frequency module 122c connected to each other. The third radio frequency module 122c is connected to the satellite communication chip 11. The first radiator 121a, the second radiator 121b, and the third radiator 121c are respectively disposed on three different sides of the mobile terminal. This allows the downward radiation patterns of the three antennas to complement each other, thereby enabling communication capabilities in a wider range of areas.

[0123] In one embodiment, the first antenna 12a, the second antenna 12b, and the third antenna 12c are all used to receive radio frequency signals from communication satellites. Figure 8 shows the downlink pattern of the satellite antenna system of the mobile terminal in the embodiment shown in Figure 7. The solid line represents the pattern of the first antenna 12a receiving the radio frequency signals from the communication satellite, the dotted line represents the pattern of the second antenna 12b receiving the radio frequency signals from the communication satellite, and the dashed line represents the pattern of the third antenna 12c receiving the radio frequency signals from the communication satellite. As shown in Figure 8, the patterns of the first antenna 12a, the second antenna 12b, and the third antenna 12c are complementary to each other. As a result, the combined coverage area of ​​the high sensitivity zones per angle for the first antenna 12a, the second antenna 12b, and the third antenna 12c is large, resulting in a wide coverage area for the mobile terminal's satellite antenna system. The satellite antenna system is an omnidirectional antenna system. This reduces the difficulty of alignment during use, allowing the mobile terminal to receive radio frequency signals from the communication satellite in a wide range of postures. It is beneficial to improve the downlink communication effect of mobile terminal communication satellite communication, so that the mobile terminal can have the function of being called by communication satellite communication.

[0124] In a specific embodiment, the strong area of ​​the EIS of the first antenna 12a covers at least the pitch angle of 0° to 60° and the azimuth angle of 0° to 360° in spherical coordinates; the strong area of ​​the EIS of the second antenna 12b covers at least the pitch angle of 60° to 180° and the azimuth angle of 180° to 360° in spherical coordinates; and the strong area of ​​the EIS of the third antenna 12c covers at least the pitch angle of 60° to 180° and the azimuth angle of 0° to 180° in spherical coordinates.

[0125] In one embodiment, the first antenna 12a, the second antenna 12b, and the third antenna 12c are all used to transmit signals to a communication satellite. The first RF module 122a of the first antenna 12a includes a power amplifier and a low-noise amplifier. The second RF module 122b of the second antenna 12b also includes a power amplifier and a low-noise amplifier. The third RF module 122c of the third antenna 12c also includes a power amplifier and a low-noise amplifier.

[0126] As shown in Figure 7, in a specific embodiment, the first radiator 121a of the above-mentioned first antenna 12a is arranged on the side of the top of the mobile terminal, the second radiator 121b of the second antenna 12b is arranged on the side of the bottom of the mobile terminal, and the third radiator 121c of the third antenna 12c is arranged on the side of the side of the mobile terminal.

[0127] FIG9 is another schematic diagram of the structure of a mobile terminal according to an embodiment of the present application. As shown in FIG9 , in one embodiment, the satellite antenna system of the mobile terminal according to the present application includes four antennas 12. Specifically, the satellite antenna system includes a first antenna 12a, a second antenna 12b, a third antenna 12c, and a fourth antenna 12d. The fourth antenna 12d includes a fourth radiator 121d and a fourth RF module 122d connected to each other. The fourth RF module 122d is connected to the satellite communication chip 11. The first radiator 121a, the second radiator 121b, the third radiator 121c, and the fourth radiator 121d are respectively disposed on four different sides of the mobile terminal.

[0128] In one embodiment, the first antenna 12a, the second antenna 12b, the third antenna 12c, and the fourth antenna 12d are all used to receive radio frequency signals from communication satellites. Figure 10 shows the downlink directional pattern of the satellite antenna system of the mobile terminal in the embodiment shown in Figure 9. The solid line represents the directional pattern of the first antenna 12a receiving the radio frequency signal from the communication satellite, the dotted line represents the directional pattern of the second antenna 12b receiving the radio frequency signal from the communication satellite, the dashed line represents the directional pattern of the third antenna 12c receiving the radio frequency signal from the communication satellite, and the dashed-dotted line represents the directional pattern of the fourth antenna 12d receiving the radio frequency signal from the communication satellite. As shown in Figure 10, the directional patterns of the first antenna 12a, the second antenna 12b, the third antenna 12c, and the fourth antenna 12d are complementary to each other. As a result, the combined coverage area of ​​the strong reception sensitivity zones per angle of the first antenna 12a, the strong reception sensitivity zones per angle of the second antenna 12b, the strong reception sensitivity zones per angle of the third antenna 12c, and the strong reception sensitivity zones per angle of the fourth antenna 12d is relatively large, resulting in a wide coverage area for the satellite antenna system of the mobile terminal. The satellite antenna system is an omnidirectional antenna system. The difficulty of satellite alignment during use is reduced, and the mobile terminal can receive the radio frequency signal of the communication satellite in a variety of postures. This is conducive to improving the downlink communication effect of the mobile terminal communication satellite communication, allowing the mobile terminal to have the function of being called by the communication satellite communication.

[0129] In a specific embodiment, the strong area of ​​the EIS of the first antenna 12a covers at least the pitch angle of 0° to 45° and the azimuth angle of 0° to 360° in spherical coordinates; the strong area of ​​the EIS of the second antenna 12b covers at least the pitch angle of 135° to 180° and the azimuth angle of 0° to 360° in spherical coordinates; the strong area of ​​the EIS of the third antenna 12c covers at least the pitch angle of 45° to 135° and the azimuth angle of 0° to 180° in spherical coordinates; and the strong area of ​​the EIS of the fourth antenna 12d covers at least the pitch angle of 45° to 135° and the azimuth angle of 180° to 360° in spherical coordinates.

[0130] The first antenna 12a, second antenna 12b, third antenna 12c, and fourth antenna 12d are all used to transmit signals to a communication satellite. The first RF module 122a of the first antenna 12a includes a power amplifier and a low-noise amplifier.
