[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In this application, terms such as "upper," "lower," "top," "bottom," "inner," and "outer" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0037] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0038] Furthermore, the terms "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0040] In addition, the terms "end" and "point" in the specification and claims of this application and the above-mentioned figure descriptions can indicate a small section of the antenna radiator relative to the antenna radiator as a whole, that is, "end" cannot be narrowly understood as the end, and "point" cannot be narrowly understood as a point.

[0041] With the development of 5G (fifth-generation mobile networks), 5G networks can operate in a variety of frequencies, including low-band, mid-band, and high-band. This diversity of frequency bands requires terminal devices to use different antennas for different frequency bands. Furthermore, with the popularization of 5G networks and the expansion of application scenarios, the demand for high-speed, low-latency, and high-capacity wireless communications continues to grow. To meet these demands, it is necessary to build more 5G base stations and increase the number of antennas in terminal devices to expand network coverage and improve transmission efficiency. Furthermore, given the pursuit of multifunctionality and lightweight design in terminal devices, terminal devices need to integrate multiple functional modules, batteries, screens, heat sinks, and other components within a limited space, which further limits the internal space of the terminal devices. Therefore, finding the right location for antenna placement within the limited space of the terminal device has become a key issue in the development of 5G communications.

[0042] In view of this, the present application discloses a terminal device that can reduce the internal space occupied by the first antenna without affecting the display quality of the display screen, thereby effectively improving the utilization rate of the terminal device's internal space. In addition, by arranging the first antenna in the non-window area, since the non-window area is located on the front of the terminal device, the possibility of the first antenna being blocked is reduced and sufficient clearance area is provided for the first antenna, thereby effectively improving the radiation performance of the first antenna.

[0043] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0044] The terminal device 100 in the embodiments of the present application may include, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a computer, a wearable device (such as a smart watch or smart bracelet), a drone, a robot, a digital camera, a smart home, a smart helmet, smart glasses, and other devices with communication functions. The terminal device 100 may also be a handheld device with wireless communication functions, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future-evolved public land mobile network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0045] See also Figure 1 , Figure 1Schematic diagram of the structure of the terminal device 100 disclosed in the embodiment of the present application. The terminal device 100 in the embodiment of the present application is described by taking a smartphone as an example, and its overall shape is generally rectangular, that is, the overall shape of the terminal body shell is generally rectangular. Other terminal devices 100 can refer to this embodiment.

[0046] See also Figure 2 and Figure 3 , Figure 2 This is an exploded view of the terminal device disclosed in the embodiment of this application. Figure 3 This is a front view of the terminal device disclosed in an embodiment of the present application. The embodiment of the present application provides a terminal device 100, which includes a housing 1, a circuit board (not shown), a display screen 3, and a first antenna 4. The circuit board is disposed in the housing 1. The display screen 3 includes a display panel 32 and a cover plate 31. The display panel 32 is disposed in the housing 1. The cover plate 31 is located above the display panel 32 and is connected to the housing 1. The side surface of the cover plate 31 facing the display panel 32 includes a window area 311 and a non-window area 312. The non-window area 312 is located outside the window area 311. The first antenna 4 is disposed in the non-window area 312, and the first antenna 4 is electrically connected to the circuit board.

[0047] The terminal device 100 provided in this application, by disposing the first antenna 4 in the non-window area 312 and electrically connecting the first antenna 4 to the circuit board, can reduce the internal space occupied by the first antenna 4 of the terminal device 100 while not affecting the display effect of the display panel 32, thereby effectively improving the utilization rate of the internal space of the terminal device 100. In addition, because the first antenna 4 is disposed in the non-window area 312, which is located on the front of the terminal device 100, the possibility of the first antenna 4 being blocked by the user during use is reduced and sufficient clearance area can be provided for the first antenna 4, thereby effectively improving the radiation performance of the first antenna 4.

[0048] It is understandable that the cover plate 31 may be made of glass.

[0049] It is understandable that the non-window area 312 includes the operable area on the cover plate 31, and the window area 311 includes the effective display area on the cover plate 31. In addition, the display screen 3 can adopt an OLED (Organic Light Emitting Diode) screen or an LCD (Liquid Crystal Display) screen, which is not limited in the embodiments of the present application. The display screen 3 can be used to display information and provide an interactive interface for the user. The shape of the display screen 3 can be a rectangle or an arc-cornered rectangle. The arc-cornered rectangle can sometimes also be called a rounded rectangle, that is, the four corners of the rectangle adopt arc transitions, and the four sides of the rectangle are roughly straight line segments.

[0050] In some embodiments, the first antenna 4 may be any one of an FPC antenna, an LDS antenna, a PDS antenna, and a metal branch antenna, that is, the first antenna 4 may include but is not limited to any one of a flexible printed circuit board antenna formed on a flexible printed circuit board (FPC), a laser direct structured antenna formed by laser direct structure (LDS), a printed direct structured antenna formed by print direct structure (PDS), and a conductive sheet antenna (such as a metal branch antenna), and the embodiments of the present application are not limited to this. Among them, the FPC antenna is connected to the motherboard of the terminal device 100 through a metal spring. The FPC antenna is light in weight, thin in thickness, and has good bendability. Therefore, when the FPC trace on the terminal device 100 is used as the first radiator 41 in the first antenna 4, it can not only reduce the space occupied by the first antenna 4 on the terminal device 100, but also improve the working performance of the first antenna 4.

[0051] See also Figure 4 , Figure 4 Schematic diagram of the structure of the first antenna disclosed in the embodiment of the present application. In some embodiments, the frequency bands supported by the first antenna 4 include but are not limited to Wireless Fidelity (WiFi) 2.4GHz or 5GHz, Low Band (LB), Middle High Band (MHB), Ultra High Band (UHB), GPS-L5, GPS-L1, B3 band, B1 band, N41 band, N78 band, etc., wherein the LB band refers to a frequency band below 1000MHz (excluding 1000MHz). The MHB band refers to a frequency band of 1000MHz-3000MHz (including 1000MHz, excluding 3000MHz). The UHB band refers to a frequency band of 3000MHz-10000MHz (including 3000MHz).

[0052] Optionally, the first antenna 4 includes a first radiator 41, a first feed point 42, a first ground point 43, and a second ground point 44. The first radiator 41 is disposed in the non-window area 312. The first feed point 42 is disposed on the first radiator 41 and adjacent to one end of the first radiator 41. The first feed point 42 is electrically connected to a circuit board. The first ground point 43 is disposed on the first radiator 41 and adjacent to the first feed point 42. The second ground point 44 is disposed at an end of the first radiator 41 away from the first feed point 42. The first and second ground points 43 and 44 are electrically connected to the circuit board. The second ground point 44 is disposed at the end away from the first feed point 42 to increase the distance between the second ground point 44 and the first feed point 42, thereby extending the signal return path of the first antenna 4, thereby increasing the resonant frequency of the first radiator 41, reducing the attenuation and interference of the signal of the first radiator 41 during transmission, and thereby improving the efficiency and stability of signal transmission.

[0053] As can be seen from the above, the first antenna 4 can be an FPC antenna, and the first radiator 41 can be an FPC radiator. Since the FPC antenna is light, thin and flexible, the FPC antenna is easy to integrate into the terminal device 100, thereby improving the communication performance of the terminal device 100.

[0054] Optionally, the terminal device 100 further includes a sensor 5, which is electrically connected to the first radiator 41, and the sensor 5 is configured to detect the electromagnetic wave absorption rate of the first antenna 4. Since the sensor 5 is used to detect the electromagnetic wave absorption rate of the first antenna 4, the sensor 5 may include but is not limited to an electromagnetic wave absorption rate (Specific Absorption Rate, referred to as SAR) sensor. The electromagnetic wave absorption rate reflects the proportion of electromagnetic energy absorbed by the human body. The higher the SAR value of the terminal device 100, the greater the electromagnetic radiation damage to the human body. The present application connects the sensor 5 to the first radiator 41. Since the first radiator 41 is located in the non-window area 312, during the daily use of the terminal device 100, the non-window area 312 is closer to the human body than other positions of the terminal device 100, making the detection of the electromagnetic wave absorption rate more reasonable and effective, thereby effectively reducing the electromagnetic radiation damage to the human body by the first antenna 4.

[0055] Optionally, the sensor 5 is electrically connected to the first ground point 43, or the sensor 5 is electrically connected to the second ground point 44. Since the sensor 5 has a corresponding matching circuit, the matching circuit will produce electromagnetic interference and impedance mismatch on the antenna on the terminal device 100, and the first ground point 43 and the second ground point 44 are both electrically connected to the ground layer of the circuit board. When the sensor 5 is electrically connected to the first ground point 43 or the second ground point 44, compared with the case where the sensor 5 is electrically connected to the first feed point 42, the electromagnetic interference to the first antenna 4 can be effectively reduced, thereby improving the working stability and anti-interference capability of the first antenna 4.

[0056] Optionally, the first antenna 4 further includes a first branch 45 and a second branch 46. The first branch 45 is located at one end of the first radiator 41, one end of the first branch 45 is electrically connected to the first ground point 43, and the other end of the first branch 45 is electrically connected to the ground layer of the circuit board. The second branch 46 is located at the other end of the first radiator 41, one end of the second branch 46 is electrically connected to the second ground point 44, and the other end of the second branch 46 is electrically connected to the ground layer of the circuit board. The first branch 45 and the second branch 46 serve as a frequency-selective filter circuit for the first antenna 4, used to tune the length of the first radiator 41. The first branch 45 includes a capacitor and an inductor connected in series, and the second branch 46 includes a capacitor and an inductor connected in series. The capacitor on the first branch 45 can be a DC blocking capacitor between the sensor 5 and the first antenna 4. This DC blocking capacitor can prevent the sensor 5 electrically connected to the first antenna 4 from being directly inductively grounded, avoiding electrostatic interference and thereby improving the detection stability of the sensor 5.

[0057] In some embodiments, the housing 1 includes a top 11 and a bottom 12 relative to each other, the non-window area 312 includes a first area 3121 adjacent to the top 11 and a second area 3122 adjacent to the bottom 12, and the first antenna 4 is disposed in the first area 3121. That is, the first antenna 4 is disposed in the first area 3121 adjacent to the top 11 of the housing 1, so that the first antenna 4 has sufficient clearance area without occupying the internal space of the terminal device 100, thereby improving the radiation performance of the first antenna 4. In addition, the first antenna 4 is disposed adjacent to the top 11, and the upper hemisphere efficiency of the first antenna 4 accounts for a higher proportion, thereby effectively improving the positioning efficiency and positioning stability of the terminal device 100. The top 11 of the housing 1 is the end away from the ground when the user holds the terminal device 100 and uses the device in portrait mode, and the bottom 12 of the housing 1 is the end facing the ground when the user holds the terminal device 100 and uses the device in portrait mode.

[0058] The first antenna 4 is set near the top. In this way, no matter whether the user holds the terminal device in portrait mode or landscape mode, the setting position of the first antenna 4 can be avoided, so that the user will not be blocked by the first antenna 4 when using the terminal device 100, thereby effectively improving the working performance of the first antenna 4.

[0059] In some embodiments, the first antenna 4 is configured to support a first frequency band, and the terminal device 100 further includes a second antenna (not shown), which is disposed within the housing 1 and electrically connected to the circuit board. The second antenna is configured to support a second frequency band. The first frequency band and the second frequency band are different frequency bands. Because the terminal device 100 can simultaneously receive and process antenna signals in two different frequency bands, the positioning accuracy and positioning stability of the terminal device 100 can be effectively improved.

[0060] Optionally, the first frequency band is the GPS-L5 band, and the second frequency band is the GPS-L1 band. The GPS-L5 band has a frequency range of 1176.45 MHz ± 1.023 MHz, and the GPS-L1 band has a frequency range of 1575.42 MHz ± 1.023 MHz. The GPS-L1 band has high signal strength and good penetration capability. The GPS-L5 band provides higher positioning accuracy and anti-interference performance, and has a higher bandwidth and lower multipath effects, providing more accurate and reliable positioning information.

[0061] It is understandable that the first antenna 4 is used to support the GPS-L5 frequency band, and the second antenna is used to support the GPS-L1 frequency band. Since the signal code rate of the GPS-L5 frequency band is higher and the spectrum density is more concentrated, the use of the signal of the GPS-L5 frequency band can improve the positioning accuracy of the terminal device 100 and achieve fast and high-precision positioning. However, the signal of the GPS-L1 frequency band has a wide coverage, which makes it impossible for the terminal device 100 to directly abandon the GPS-L1 frequency band and only use the GPS-L5 frequency band, which will cause compatibility problems for the signal receiver. Therefore, the terminal device 100 can simultaneously receive and process satellite signals from both the GPS-L1 and GPS-L5 frequency bands, thereby effectively improving the positioning accuracy and positioning stability of the terminal device 100. In addition, the present application uses half the wavelength of the balanced mode as the resonant length of the first antenna 4, thereby increasing the effective radiation area of ​​the first antenna 4, thereby improving the working performance of the first antenna 4.

[0062] Of course, as another example, the first antenna 4 may also be used to support the GPS-L1 frequency band, and the second antenna may be used to support the GPS-L5 frequency band, which is not limited in the embodiment of the present application.

[0063] Please refer again Figure 2Optionally, the housing 1 includes a top 13 and a bottom 14 relative to each other, and the second antenna is arranged at the top 13, or the second antenna is arranged near the top 13. This can effectively reduce interference with the signal from other internal components of the terminal device 100, such as battery radiation generated by the battery, central processing unit, etc., thereby improving the operating performance of the second antenna and making the second antenna's signal reception and transmission capabilities stronger. In addition, when the user holds the terminal device 100, the second antenna will be blocked, resulting in affected signal transmission and reception. Based on this, arranging the second antenna at the top 13, or arranging the second antenna near the top 13, can reduce the obstruction of the second antenna when the user holds the terminal device 100, thereby improving the stability of the second antenna's signal transmission and reception. It can be understood that the housing 1 includes a back cover and a middle frame, the middle frame enclosing and connected to the back cover, and the middle frame includes a top frame and a bottom frame arranged opposite each other, as well as a first side frame and a second side frame connected to the top frame and the bottom frame. Among them, the top 13 refers to the top frame, and the bottom 14 refers to the bottom frame. In addition, the back cover and the middle frame can be integrally formed or separately formed, which is not limited in the embodiments of the present application.

[0064] It is understood that the type of the second antenna can be the same as that of the first antenna 4. That is, the first antenna 4 and the second antenna can both be FPC antennas, thereby improving the manufacturing efficiency of the first antenna 4 and the second antenna. Of course, the types of the first antenna 4 and the second antenna can also be different, and this embodiment of the application does not specifically limit this. In other words, the materials or molding methods of the first antenna 4 and the second antenna can be the same or different, and this application does not limit this.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
