As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0040] Figure 1A schematic diagram showing the structure of an electronic device according to an embodiment of the present application is shown. Figure 2 A cross-sectional view of an electronic device according to an embodiment of the present application is shown, Figure 3 Show Figure 2 The enlarged schematic diagram of A in the figure is shown in Figures 1 to 3 An embodiment of the present application provides an electronic device 10, which includes a middle frame, a display screen 200, a cover frame, a first radiator 300, a first feeding structure 500, and a second radiator 400.

[0042] In some other embodiments, the electronic device 10 may also be a folder, so that the electronic device 10 can be switched between an unfolded state and a folded state.

[0043] The display screen 200 can be used to display information such as images and texts. The display screen 200 includes a bendable flexible display screen. The flexible display screen can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0044] The middle frame includes a frame 100 and a middle plate 601, and the middle frame defines a cavity. The frame 100 can be a hollow frame structure. For example, the frame 100 can include a top edge, a bottom edge and a side edge, and the frame 100 and the middle plate 601 together constitute the middle frame of the electronic device, that is, the middle plate 601 is located in the space surrounded by the display screen 200, the frame 100 and the back cover 603. The middle frame is used to provide support for multiple electronic devices in the electronic device 10, so as to install multiple electronic devices in the electronic device 10 together, for example, the mainboard 600 can be installed on the middle frame, and the mainboard 600 can be installed in the space between the middle plate 601 and the display screen 200 or the middle plate 601 and the back cover 603. For example, electronic devices such as the mainboard 600 and the battery 602 in the electronic device 10 can be installed in the space between the middle plate 601 and the back cover 603 for fixing. In another example, the electronic device 10 can also include a sub-board, such as various electrical connectors, mics or sound-generating devices, etc. can be installed on the sub-board.

[0045] In one example, at least part of the display screen 200 is disposed in the cavity and constitutes a surface of the electronic device 10, and the display screen 200 includes a display area 210 and a non-display area 220 located at the edge of the display area 210. The display area 210 performs the display function of the display screen 200, and is used to display information such as images and texts. The non-display area 220 does not display images.

[0046] The cover frame is disposed in the non-display area 220 at the edge of the display area 210. In some examples, the cover frame is disposed on a side of the display screen 200 that is away from the middle frame.

[0047] In one example, the display screen 200 further includes a cover plate 230 (e.g., a glass cover plate, a resin cover plate) and a display panel 240 located below the cover plate 230, and the cover plate 230 can cover the outside of the display panel 240 to protect the display panel 240. The display panel 240 corresponds to the first area of ​​the display area 210 (i.e., the part of the display panel that does not include the second area 2401) and includes a plurality of pixels, and the plurality of pixels can be arranged in the row and column direction, and the shape of each pixel can be rectangular or square or other suitable shapes on the plane, and each pixel can include a plurality of light-emitting elements formed by inorganic particles or organic particles. The first area can also have signal wiring and power wiring for providing drive signals and power to the pixels. For example, a first voltage line for providing a high potential voltage to each pixel and a second voltage line for providing a low potential voltage lower than the high potential voltage to each pixel can be arranged in the first area of ​​the display panel 240. In addition, although not shown in the drawings, the first area of ​​the display panel 240 can also include data lines for transmitting data signals to each pixel, scanning lines for transmitting scanning signals to each pixel, initialization voltage lines and other wiring. The second area 2401 of the display panel 240 corresponding to the non-display area 220 may be arranged with a transmission wiring (or bus pattern BP) for transmitting a driving signal or power to the first area, a test pad TPD, and a driving circuit or driving element for driving the first area.

[0048] It should be noted that the display screen 200 can be disposed in its entirety in the cavity, that is, the cover plate 230 and the display panel 240 are both located in the cavity, and the cover plate 230 can be flush with the frame 100. Alternatively, the display screen 200 can be partially disposed in the cavity, for example, the display panel 240 is disposed in the cavity, and the cover plate 230 can be partially (slightly) disposed beyond the frame 100. It is understandable that, regardless of whether the display screen is disposed in its entirety or partially in the cavity, the cover plate 230 needs to be installed on the middle frame, for example, the edge of the cover plate 230 can be installed in the groove formed by the frame 100, and the cover plate 230 and the frame 100 can be connected by filling a curing material such as glue.

[0049] Radiator: It is a device in the antenna used to receive / send electromagnetic wave radiation. In some cases, the "antenna" in a narrow sense is understood as a radiator, which converts the waveguide energy from the transmitter into radio waves, or converts radio waves into waveguide energy, which is used to radiate and receive radio waves. The modulated high-frequency current energy (or waveguide energy) generated by the transmitter is transmitted to the transmitting radiator via the feeder line, and is converted into a certain polarized electromagnetic wave energy by the radiator and radiated in the desired direction. The receiving radiator converts a certain polarized electromagnetic wave energy from a specific direction in space into modulated high-frequency current energy, which is transmitted to the receiver input via the feeder line.

[0050] The radiator may include a conductor with a specific shape and size, such as a linear or sheet-like shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator, or the radiator of the linear antenna, has a line diameter (for example, including thickness and width) much smaller than the wavelength (for example, the dielectric wavelength) (for example, less than 1 / 16 of the wavelength), and the length may be comparable to the wavelength (for example, the dielectric wavelength) (for example, according to the resonant mode of the radiator, the length may be determined to be around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, the sheet radiator may include a microstrip antenna, or a patch antenna, such as a planar inverted F antenna (also known as PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (for example, a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste, etc. The shape of the sheet radiator includes a circle, a rectangle, a ring, etc., and the present application does not limit the specific shape.

[0051] The first radiator 300 is disposed in the non-display area 220, and the first radiator 300 has a first polarization direction at the first resonant frequency, and the first radiator 300 is used to radiate electromagnetic waves in the first polarization direction. The second radiator 400 is disposed on the inner side of a side edge of the middle frame adjacent to the first radiator 300 and the second radiator 400 extends toward the inside of the electronic device 10, and the second radiator 400 has a second polarization direction at the first resonant frequency, and the second radiator 400 is used to radiate electromagnetic waves in the second polarization direction. The first polarization direction and the second polarization direction are orthogonal.

[0052] It is understandable that when an electromagnetic wave propagates in space, the direction of its electric field changes in a certain direction, and this change is the polarization of the electromagnetic wave. In other words, the oscillation plane of the electric field defines the polarization direction of the electromagnetic wave. It can be seen that the oscillation direction (or oscillation plane) of the first electromagnetic wave radiated by the first radiator 300 in three-dimensional space and the oscillation direction (or oscillation plane) of the second electromagnetic wave radiated by the second radiator 400 in three-dimensional space are orthogonal to each other.

[0053] It should be noted that the first radiator 300 and the second radiator 400 can be arranged on the same side close to the frame 100, such as the top side, and the first radiator 300 is arranged in the area of ​​the non-display area 200 corresponding to the top side. The first radiator 300 can be arranged in contact with the cover plate 230 corresponding to the area, such as attached to the surface of the cover plate 230 corresponding to the area, or embedded in the cover plate 230 corresponding to the area, or the first radiator 300 can also be located below the cover plate 230 corresponding to the area. Correspondingly, the second radiator 400 can be arranged on the inner side of the top side, such as attached to the inner surface of the top side, and the second radiator 400 extends toward the inside of the electronic device 10.

[0054] Exemplarily, the first radiator 300 may include one or more metal parts. For example, the non-display area 220 includes at least a fourth non-display sub-area. The four non-display sub-areas are respectively located around the display area 210, and the four non-display sub-areas extend along the four edges of the display area 210 respectively. At least one of the four non-display sub-areas is provided with one or more metal parts, and the metal parts extend along the corresponding non-display sub-areas to form the first radiator 300.

[0055] Figure 4 FIG. 1 is a schematic diagram showing the internal structure of an electronic device 10 according to an embodiment of the present application. Figure 5 Show Figure 4 The enlarged schematic diagram of B in the figure is shown in Figures 3 to 5 The first feeding structure 500 is disposed in the cavity and below the first radiator 300 , and the first feeding structure 500 parasitically couples and feeds the first radiator 300 .

[0056] In the embodiment of the present application, the first feeding structure 500 parasitic-couples and feeds the first radiator 300 , and the first radiator 300 radiates the electrical signal fed by the first feeding structure 500 , thereby realizing the radiation function of the first radiator 300 .

[0057] In some examples, the second radiator 400 may include one or more metal pieces, which are disposed inside a side of the frame 100 adjacent to the first radiator 300 and the second radiator 400 extends toward the inside of the electronic device 10 .

[0058] In the embodiment of the present application, the sizes of the first radiator 300 and the second radiator 400 are not limited. For example, the size of the first radiator 300 in the x-direction of the electronic device 10 may be greater than, equal to, or smaller than the size of the second radiator 400, the size of the first radiator 300 in the y-direction of the electronic device 10 may be greater than the size of the second radiator 400, and the size of the first radiator 300 in the z-direction of the electronic device 10 may be smaller than the size of the second radiator 400.

[0059] In one example, a size of the first radiator 300 in the x-direction of the electronic device 10 is equal to a size of the second radiator 400 .

[0060] According to the exemplary description of the embodiment of the present application, the first radiator 300 utilizes the space of the non-display area 220 of the display screen 200 to avoid the first radiator 300 occupying the display area 210, so that the first radiator 300 does not affect the display effect of the electronic device 10. Secondly, the position design of the second radiator 400 enables it to make full use of the space of the internal cavity of the frame 100, and try to avoid the second radiator 400 from interfering with the internal components of the electronic device. Furthermore, the embodiment of the present application has two radiators through the arrangement of the first radiator 300 and the second radiator 400, for example, to achieve electromagnetic wave radiation of the same / different frequency bands, thereby improving the antenna efficiency of the embodiment of the present application. And the polarization directions of the first radiator 300 and the second radiator 400 are set to be orthogonal, that is, the polarization directions of the two are perpendicular to each other. Such an arrangement can effectively reduce the mutual interference of electromagnetic waves of the same frequency band or electromagnetic waves of different frequency bands emitted by the first radiator 300 and the second radiator 400, increase the isolation between the first radiator 300 and the second radiator 400, thereby improving the antenna efficiency, and then improving the performance of the antenna and the signal reception quality.

[0061] In the embodiments of the present application, “orthogonal” refers to a state in which the angle formed by a straight line and a straight line, a straight line and a plane, or a plane and a plane is 89° to 91°.

[0062] In some embodiments, the frame 100 may be made of dielectric material (such as plastic). The side of the frame 100 facing the inside of the electronic device 10 may be provided with a plurality of metal patches and / or a plurality of metal structures such as flexible circuit boards. The metal structure may be used to form the second radiator 400 .

[0063] Exemplarily, the second radiator 400 may include a patch antenna, which is attached to the inner side of a side of the frame 100 adjacent to the first radiator 300 .

[0064] In some embodiments, the first feeding structure 500 includes a first plane portion 510, a second plane portion 520, and a first feed source 530. The first plane portion 510 is disposed in the groove formed by the display screen 200 and the side, such as the top side, for example, the first plane portion 510 is disposed at the bottom of the groove formed by the top side, a portion of the bottom surface of the cover plate 230 abuts against the first plane portion 510, and a solidified material is filled in the gap between the cover plate 230 and the groove. The first plane portion 510 and the first radiator 300 are spaced parallel to each other, such as the cover plate 230 or a portion of the cover plate 230 or the solidified material. The first radiator 300 and the first plane portion 510 are parasitically coupled, that is, the first plane portion 510 transfers energy with the first radiator 300 by parasitic coupling, so as to feed the RF signal transmitted by the RF circuit to the first radiator 300. The parasitic coupling can effectively improve the bandwidth and gain of the first radiator 300, improve the quality and stability of wireless communication, and enhance the radiation efficiency and performance of the first radiator 300.

[0065] See also Figure 3 and Figure 5 The second plane portion 520 is located below the first plane portion 510 and is vertically connected to the first plane portion 510, and the second plane portion 520 is arranged on the inner wall of the side of the frame, for example, it is attached to the surface of the inner wall of the top edge. The first feed source 530 is arranged on the second plane portion 520, and the first feed source 530 provides an electrical signal to the first radiator 300 through the second plane portion 520 and the first plane portion 510 to ensure the normal operation of the first radiator 300.

[0066] In the embodiment of the present application, in order to realize the installation of the display screen 200 and the frame 100, it is usually necessary to open a corresponding groove on the side. In the embodiment of the present application, the first plane part 510 is set in the groove between the side of the display screen 200 and the frame 100, which effectively utilizes the space of the electronic device 10 and improves the utilization rate of the internal space of the electronic device 10. Secondly, the first plane part 510 is set in the groove between the side of the display screen 200 and the frame 100, so that the first plane part 510 of the first feeding structure 500 maintains an appropriate distance from other components inside the electronic device 10, reduces the interference of the first plane part 510 of the first feeding structure 500 on other components of the electronic device 10, and ensures the rationality and neatness of the layout inside the device.

[0067] Referring to the above description of this article, the display screen 200 also includes a cover plate 230 (such as a glass cover plate, a resin cover plate) and a display panel 240 located below the cover plate 230. The cover plate 230 and the display panel 240 are arranged along the thickness direction (z direction) of the electronic device 10. The cover plate 230 abuts against the edge of the side of the frame 100. A gap is formed between the display panel 240 and the side of the frame 100. The first planar portion 510 is arranged between the edge of the side of the frame 100 and the upper half, and the second planar portion 520 extends from the edge of the side of the frame 100 to the inner side of the side of the frame 100. Such an arrangement can make the first feeding structure 500 more compact and efficient, and further optimize the internal space layout of the electronic device 10.

[0068] In other examples, the display screen 200 also includes a cover plate 230 (e.g., a glass cover plate, a resin cover plate) and a display panel 240 located below the cover plate 230. The cover plate 230 and the display panel 240 are arranged along the thickness direction (z direction) of the electronic device 10. The cover plate 230 abuts against the edge of the side of the frame 100. A gap is formed between the display panel 240 and the side of the frame 100. The first planar portion 510 and the second planar portion 520 are arranged in the gap. In this way, the internal space layout of the electronic device 10 is further optimized under the premise that the first feeding structure 500 can be parasitically coupled with the first radiator.

[0069] In some embodiments, the first radiator 300 and the second radiator 400 can be disposed on the same side of the electronic device 10 , or can be disposed on different sides of the electronic device 10 .

[0070] Exemplarily, the first radiator 300 and the second radiator 400 are disposed on one side of the electronic device 10 in the length direction (ie, the y direction), which is not limited in the embodiments of the present application.

[0071] In the embodiment of the present application, when the first radiator 300 and the second radiator 400 are arranged on one side of the electronic device 10 in the length direction, the first radiator 300 and the second radiator 400 can be extended along the width (i.e., the x direction) of the electronic device 10, so that the extended length of the first radiator 300 and the second radiator 400 can meet the electrical length required by the resonant frequency band, thereby matching the required operating frequency band. For example, if it is necessary to work in the 1 / 4 mode of the A band, it is necessary to calculate the electrical length of the radiator based on the frequency band and the 1 / 4 resonant mode to ensure that the radiator meets the required resonance conditions and frequency requirements.

[0072] Exemplarily, the first radiator 300 is disposed on one side of the electronic device 10 in the length direction, and the second radiator 400 is disposed on the other side of the electronic device 10 in the length direction, which is not limited in the embodiments of the present application.

[0073] In an embodiment of the present application, when the first radiator 300 is arranged on one side of the electronic device 10 in the length direction and the second radiator 400 is arranged on the other side of the electronic device 10 in the length direction, the first radiator 300 and the second radiator 400 can extend along the width of the electronic device 10, thereby enhancing the radiation performance of the first radiator 300 and the second radiator 400.

[0074] Exemplarily, the first radiator 300 and the second radiator 400 are disposed on one side of the electronic device 10 in the width direction, which is not limited in the embodiments of the present application.

[0075] In the embodiment of the present application, when the first radiator 300 and the second radiator 400 are arranged on one side of the electronic device 10 in the width direction, the first radiator 300 and the second radiator 400 can extend along the width of the electronic device 10 to enhance the radiation performance of the first radiator 300 and the second radiator 400.

[0076] Exemplarily, the first radiator 300 is disposed on one side of the electronic device 10 in the width direction, and the second radiator 400 is disposed on the other side of the electronic device 10 in the width direction, which is not limited in the embodiments of the present application.

[0078] It should be noted that, in some other embodiments, the first radiator 300 and the second radiator 400 may also have other shapes, lengths, and extension directions, which are not limited in the embodiments of the present application.

[0079] In some embodiments, the first radiator 300 of the present application is disposed on the surface of the display screen 200 away from the main board 600, so that the first radiator 300 can be exposed outside the display screen 200. The first radiator 300 and the first feeding structure 500 are respectively disposed on both sides of the display screen 200, so that the first radiator 300 and the first feeding structure 500 are electrically connected by parasitic coupling. It should be noted that the first radiator 300 can also be disposed at other positions, as long as the polarization direction of the first radiator 300 is orthogonal to the polarization direction of the second radiator 400.

[0080] It is understandable that the short distance between the first radiator 300 and the second radiator 400 will result in poor isolation between the first radiator 300 and the second radiator 400, which is easy to affect each other, thereby causing the radiation performance of the two first radiators 300 and the second radiator 400, such as a decrease in transmission efficiency, and may also cause damage to components such as filters. Based on this, in some examples, the present application sets the first radiator 300 on the surface of the display screen 200 away from the main board 600, and the second radiator 400 is set on the side close to the frame away from the display screen 200. In this way, the distance between the first radiator 300 and the second radiator 400 is increased as much as possible, so that the first radiator 300 and the second radiator 400 can still have a better isolation, so that the first radiator 300 and the second radiator 400 have better radiation performance, and the service life of components such as filters is longer, so that the electronic device 10 has better communication performance.

[0081] In some embodiments, see Figure 5 The second planar portion 520 defines a first slot 521, a first feed source 530 is disposed in the first slot 521, the first feed source 530 is electrically connected to the second planar portion 520, and the first feed source 530 is configured as an excitation source for the first radiator 300. The first feed source 530 is disposed in the first slot 521, and the first feed source 530 is electrically connected to the second planar portion 520.

[0082] It can be understood that the electrical connection between the first feed source 530 and the second planar portion 520 means that the output end of the first feed source 530 is connected to, for example, the right end of the first slot 521, and the input end of the first feed source 530 is connected to, for example, the left end of the first slot 521, or, the output end of the first feed source 530 is connected to, for example, the left end of the first slot 521, and the input end of the first feed source 530 is connected to, for example, the right end of the first slot 521, which enables a complete current loop to be formed between the first feed source 530 and the second planar portion 520 and the first planar portion 510.

[0083] Exemplarily, the first slit 521 is disposed on a side of the second planar portion 520 facing away from the first planar portion 510 .

[0084] In other examples, the first slit 521 can also be disposed on both sides of the second planar portion 520 in the left-right direction, and the location of the first slit 521 is not limited herein.

[0085] According to the embodiment of the present application, an appropriate distance can be maintained between the first feed source 530 and the electronic components in the electronic device 10, thereby reducing the electromagnetic interference of the first feed source 530 on the electronic components in the electronic device 10, thereby improving the stability of the electromagnetic environment inside the electronic device 10.

[0086] In some embodiments, the first slit 521 is disposed in the middle of the second planar portion 520 on a side facing away from the first planar portion 510 , and the first collapse source 530 is disposed in the first slit 521 .

[0087] In some embodiments, see Figure 3 and Figure 5 A through slot 522 is defined at the connection between the first planar portion 510 and the second planar portion 520, and the through slot 522 is connected to the first slit 521. With this arrangement, the current output from the output end of the first feed source 530 can flow from the first planar portion 510 to the second planar portion 520, and then return from the second planar portion 520 to the first planar portion 510, and finally form a complete current loop with the input end of the first feed source 530, so that the current direction of the first radiator 300 can always change with the change of the current direction on the first planar portion 510, thereby exciting an electromagnetic wave with a first polarization direction on the first radiator 300.

[0088] In the embodiment of the present application, the first feeding structure 500 is set to a ring shape, so that a complete current loop is formed between the first plane portion 510 and the second plane portion 520, and the current direction of the excitation current on the first plane portion 510 is always a changing unidirectional current. For example, it flows from the left end to the right end of the first plane portion 510, or from the right end to the left end of the first plane portion 510, to ensure that the first polarization direction of the first radiator 300 is fixed. In some examples, the size of the first feeding structure 500 can be appropriately reduced, for example, the size of the first feeding structure 500 in the x direction can be much smaller than the size of the first radiator 300, which is conducive to reducing the occupation of the internal space of the electronic device 10 by the first feeding structure 500.

[0089] In some embodiments, see Figure 5 , the embodiment of the present application may further include a first grounding member 700 and a second grounding member 800, the electronic device 10 further includes a middle plate 601, one end of the first grounding member 700 is connected to the first feeding structure 500, the other end of the first grounding member 700 is connected to the middle plate 601, one end of the second grounding member 800 is connected to the first feeding structure 500, and the other end of the second grounding member 800 is connected to the middle plate 601, so that the first feeding structure 500 is electrically connected to the middle plate 601 to achieve grounding. Secondly, by setting the two grounding members, the first feeding structure 500 forms a stable and low-impedance current loop, reducing voltage fluctuations and noise in the current loop.

[0090] Exemplarily, one end of the first grounding member 700 is connected to the second planar portion 520, and the other end of the first grounding member 700 is connected to the grounding port of the mainboard 600, one end of the second grounding member 800 is connected to the second planar portion 520, and the other end of the second grounding member 800 is connected to the grounding port of the mainboard 600, so that the first feeding structure 500 is electrically connected to the grounding port of the mainboard 600 to achieve grounding.

[0091] It can be understood that the middle plate 601 and the main plate 600 together form the ground of the entire electronic device, and grounding can be achieved whether it is directly connected to the middle plate 601 or connected to the ground port of the main plate 600.

[0092] In some embodiments, the connection point between the first grounding member 700 and the second planar portion 520 and the connection point between the second grounding member 800 and the second planar portion 520 are respectively located at two sides of the extension direction of the second planar portion 520 .

[0093] Figure 6 FIG. 1 is a schematic diagram showing the internal structure of an electronic device 10 according to an embodiment of the present application. Figure 7 Show Figure 6 In some embodiments, see Figure 3 , Figure 6 as well as Figure 7 The present application also includes a second feeding structure 900, one end of which is connected to the second radiator 400, and the other end of which is connected to the main board 600, so as to ensure that the current can be effectively transferred from the second feeding structure 900 to the second radiator 400, thereby achieving the radiation of the signal of the second radiator 400. Secondly, a second feed source 1000 is arranged on the second feeding structure 900, and the second feed source 1000 serves as an interface for inputting or outputting electrical signals, so as to ensure that the electrical signals can effectively enter or leave the second feeding structure 900.

[0094] In the embodiment of the present application, the second feeding structure 900 feeds power to the second radiator 400 , and the second radiator 400 radiates the electrical signal fed by the second feeding structure 900 , thereby realizing the radiation function of the second radiator 400 .

[0095] It should be noted that a radio frequency chip is provided on the main board 600, and the radio frequency chip is used to realize the mutual conversion between digital signals and radio frequency signals, and the first radiator 300 and the second radiator 400 are used to send and receive radio frequency signals.

[0096] The mainboard 600 may also include a substrate, an application processor (AP) chip, and a plurality of baseband (BB) chips. The application processor chip and the plurality of baseband chips are connected to the substrate, and the application processor chip is electrically connected to one or more of the plurality of baseband chips, and some of the plurality of baseband chips are electrically connected to each other.

[0097] In some embodiments, the substrate may include one or more circuit boards. The circuit board may be a printed circuit board (PCB) or a flexible printed circuit board (FPC). Exemplarily, the substrate may be composed of a printed circuit board and / or a flexible circuit board. Exemplarily, the substrate may be a single-layer board or a multi-layer board. The present application does not specifically limit the type and structure of the substrate. The substrate may include a metal layer, and the electronic component may also be electrically connected to the metal layer to achieve grounding. In an embodiment of the present application, the metal layer of the circuit board may also be used as a grounding plate for the electronic component.

[0098] In some embodiments, the present application further includes a radio frequency module, which is used to modulate a digital signal into a radio frequency signal and radiate it to the outside, and to modulate a radio frequency signal received from the outside into a digital signal, so that the terminal device can realize the signal receiving and transmitting function. The radio frequency module may include a radio frequency chip, which is electrically connected to the first radiator 300 and the second radiator 400, and the radio frequency chip is used to realize the mutual conversion between digital signals and radio frequency signals, and the first radiator 300 and the second radiator 400 are used to send and receive radio frequency signals.

[0099] In addition, the RF module may also include devices such as RF amplifiers, filters, mixers and frequency synthesizers connected between the RF chip and the first radiator 300 and the second radiator 400, so that the RF module can realize functions such as signal amplification, frequency conversion, and frequency synthesis to ensure the reliability and stability of signal communication.

[0100] The RF module can realize functions such as signal amplification, frequency conversion, and frequency synthesis to ensure the reliability and stability of signal communication.

[0101] In some embodiments, see Figure 5 and Figure 7 The second feeding structure 900 defines a second slot 910, and the second feed source 1000 is electrically connected to the second feeding structure 900, and the second feed source 1000 is configured as an excitation source for the second radiator 400. The second feed source 1000 is disposed in the first slot 521, and the second feed source 1000 is electrically connected to the second radiator 400 and the main board 600, respectively.

[0102] In some embodiments, see Figure 5 and Figure 7 The present application also includes a third grounding member 1100 , and the electronic device 10 also includes a mainboard 600 , one end of the third grounding member 1100 is connected to the second radiator 400 , and the other end of the third grounding member 1100 is connected to the mainboard 600 .

[0103] In some embodiments, see Figure 3 and Figure 7 The second radiator 400 includes an extension plane 410 and a bending plane 420, the extension plane 410 and the bending plane 420 are connected, the extension plane 410 is arranged on the inner side of a side edge of the frame 100 adjacent to the first radiator 300 and is perpendicular to the first radiator 300, and the bending plane 420 is bent and extended toward the inside of the electronic device 10.

[0104] When the second radiator 400 is fed with excitation, the currents on the second radiator 400 parallel to the first polarization direction cancel each other, and the currents on the second radiator 400 parallel to the second polarization direction excite the second radiator to form electromagnetic waves in the second polarization direction.

[0105] The first radiator 300 excites a half-wavelength resonant mode at the first resonant frequency through the parasitic coupling of the first feeding structure 500. At this time, a standing wave current alternately distributed along the length direction is formed on the surface of the first radiator 300, and the electromagnetic wave generated thereby has the characteristic of being polarized in the horizontal direction, that is, the first polarization direction.

[0106] The second radiator 400 is fed with an excitation signal through the second feeding structure 900, and the extension plane 410 of the second radiator 400 is arranged orthogonally to the first radiator 300. When the excitation signal is loaded, the extension plane 410 generates a conduction current, and the geometric configuration of the bending plane 420 causes the current components parallel to the first polarization direction to cancel each other out due to the phase reversal. At this time, the dominant current on the surface of the second radiator 400 is concentrated in the vertical direction of the extension plane 410, exciting a vertically polarized electromagnetic wave orthogonal to the first polarization direction, that is, the second polarization direction.

[0107] It should be noted that by setting the standing wave current of the first radiator 300 and the conduction current of the second radiator 400 to be spatially orthogonal, the two form a polarization orthogonal radiation field at the first resonant frequency. This design effectively reduces the mutual coupling interference between the two radiators.

[0108] In some examples, the second radiator 400 may include a patch antenna, a back panel is provided on the side of the frame 100 facing away from the display screen 200, the extension plane 410 is attached to the inner side of a side edge of the frame 100 adjacent to the first radiator 300, and the bending plane 420 is attached to the back panel.

[0109] Among them, the patch antenna design without the need for cables has become a type of antenna structure commonly used in electronic devices 10 .

[0110] In some examples, the connecting surface between the frame 100 and the back panel is an arc-shaped surface, the extension plane 410 fits the inner side surface of the frame 100, and the extension plane 410 extends along the thickness direction of the electronic device 10, and the bending plane 420 fits the arc-shaped surface between the frame 100 and the back panel and extends to the inner side surface of the back panel, and the bending plane 420 extends along the length direction of the electronic device 10. In this way, the second radiator 400 can completely fit the inner side surfaces of the frame 100 and the back panel, so that the frame 100 and the back panel can provide sufficient support force for the second radiator 400 to prevent the second radiator from deforming.

[0111] In other examples, the extension plane 410 may not be attached to the inner side of the frame. The extension plane 410 is disposed in the cavity of the frame 100. The extension plane 410 extends along the thickness direction of the electronic device 10. The extension plane 410 and the bending plane 420 are disposed perpendicularly to each other, and the bending plane 420 extends along the length direction of the electronic device 10.

[0112] In some embodiments, when the first radiator 300 is parasitically coupled by the first feeding structure 500, the first radiator 300 resonates in a 1 / 2 wavelength mode, and its polarization direction is the x direction parallel to the first radiator 300. On the other hand, the second radiator 400 is excited at the second feeding structure 900 by the second feed source 1000, and the monopole mode of the second radiator 400 can be excited, and the overall equivalent direction of the current is the y direction, so the polarization direction of the first radiator 300 and the polarization direction of the second radiator 400 are perpendicular to each other, so that the first radiator 300 and the second radiator 400 achieve good polarization isolation and have good isolation.

[0113] The gain of an antenna is a parameter that represents the total efficiency of the antenna's radiation energy concentration and its energy conversion capability. It is used to measure the antenna's ability to send and receive signals in a specific direction. Specifically, it refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiating unit at the same point in space under the condition of equal input power. It is usually expressed in dBi. Therefore, the gain can quantitatively describe the degree to which the antenna radiates the input power in space. An antenna with high gain can concentrate energy in a certain direction, thereby achieving a longer communication distance or a higher signal-to-noise ratio. Among them, Figure 8 A spatial simulation diagram of the antenna gain corresponding to the first radiator 300 when omnidirectionally radiating is shown, and the gain of the first radiator 300 in the -y direction gradually increases. Fig. 9The spatial simulation diagram of the antenna gain corresponding to the second radiator 400 when omnidirectionally radiating is shown, and the gain of the second radiator 400 in the y direction gradually increases. Therefore, the radiation energy directions of the first radiator 300 and the second radiator 400 of the present application are complementary, which means that the first radiator 300 and the second radiator 400 are emitted in different directions, but the radiation energies of the first radiator 300 and the second radiator 400 complement each other, thereby improving the emission energy of the entire space, and then improving the coverage and uniformity of the signal.

[0114] Return loss is a reflection coefficient expressed in logarithmic form. The reflection coefficient is the ratio of the reflected signal power reflected from the antenna's RF input signal to the input signal power, usually expressed in decibels (dB). Ideally, the impedance of the antenna and RF circuit are perfectly matched, and there is no reflected signal at all. In this case, the return loss is infinitely small. However, in engineering, it is impossible for the impedance of the antenna and RF circuit to be perfectly matched. Therefore, the reflected signal must exist. The worst case is that the RF input signal is completely reflected back, and the return loss is infinite. Therefore, the lower the return loss value, the better the antenna performance. For example Fig.10 As shown, Fig.10 The schematic diagram of the S11 parameter waveform of the first radiator 300 and the second radiator 400 of the present application is shown. The pink curve is the variation curve of the maximum efficiency that can be achieved by the second radiator 400, and the black curve is the variation curve of the total efficiency of the second radiator 400, where the total efficiency = maximum efficiency - return loss. The brown curve is the variation curve of the maximum efficiency that can be achieved by the first radiator 300, and the light blue curve is the variation curve of the total efficiency of the first radiator 300. Fig.10 As shown in the total efficiency data at the marked positions of the middle triangle marks 1, 2 and 3, the peak values ​​of the total efficiency of the second radiator 400 and the first radiator 300 are -6.2db and -5.95db respectively, and the black curve and the light blue curve almost reach the peak value, indicating that the return loss is very small, and the total efficiency of the first radiator 300 and the second radiator 400 is close to the maximum efficiency, which can illustrate the effectiveness of the solution of the present application.

[0115] It should be noted that the S11 parameter is usually a negative number. The smaller the S11 parameter is, the smaller the antenna return loss is and the smaller the energy reflected by the antenna itself is. In other words, more energy actually enters the antenna and the higher the system efficiency of the antenna is. The larger the S11 parameter is, the greater the antenna return loss is and the lower the system efficiency of the antenna is.

[0116] Fig.11 The return loss variation curves of the first radiator 300 and the second radiator 400 of the present application are shown in FIG. Fig.11, the green curve is the change curve of the return loss of the second radiator 400, the red curve is the change curve of the return loss of the second radiator 400, and the orange curve is the isolation between the first radiator 300 and the second radiator 400. Fig.11 The green and red curves of the variation curves shown have good resonance near 2.2 GHz, indicating that the energy loss of the first radiator 300 and the second radiator 400 is low in this frequency band. Secondly, the isolation near the 2.2 GHz frequency band is -19 db, which indicates that the mutual interference between the first radiator 300 and the second radiator 400 is small, thereby ensuring the stability and reliability of the first radiator 300 and the second radiator 400.

[0117] In the above embodiments, the first radiator 300 or the second radiator 400 may be functionally applied to a cellular antenna, a WiFi antenna, a Bluetooth antenna, etc., and may structurally include a monopole antenna, a dipole antenna, etc.

[0118] In some embodiments, the number of the first radiators 300 may be one or more. The provision of multiple first radiators 300 can multiply the capacity and spectrum utilization of the communication system of the electronic device 10 without increasing the bandwidth.

[0119] Exemplarily, the number of the first radiators 300 is two, and the two first radiators 300 are respectively arranged on both sides of the electronic device 10 in the length direction. Since the non-display area 220 is arranged around the display area 210, the two first radiators 300 can be arranged on both sides of the display screen 200 in the length direction, so that the two first radiators 300 fall into the non-display area 220 at the same time.

[0120] In order to ensure that the polarization directions of the two first radiators 300 remain consistent, the extension directions of the two first radiators 300 are parallel.

[0121] In some other embodiments, the two first radiators 300 may also be disposed on both sides of the display screen 200 of the electronic device 10 in the width direction, which is not limited in the embodiments of the present application.

[0122] In some embodiments, the number of the second radiator 400 may be one or more. The provision of multiple second radiators 400 can multiply the capacity and spectrum utilization of the communication system of the electronic device 10 without increasing the bandwidth.

[0123] Exemplarily, the number of the second radiators 400 is two, and the two second radiators 400 are respectively disposed on two inner side surfaces of the frame 100 in the length direction.

[0124] In some other embodiments, the two second radiators 400 may also be disposed on two inner side surfaces of the frame 100 of the electronic device 10 in the width direction, which is not limited in the embodiments of the present application.

[0125] According to the electronic device provided by the embodiment of the present application, the first radiator 300 utilizes the space of the non-display area 220 of the display screen 200 to avoid the first radiator 300 occupying the display area 210, so that the first radiator 300 does not affect the display effect of the electronic device 10. Secondly, the position design of the second radiator 400 enables it to fully utilize the space inside the frame 100 to avoid the second radiator 400 from interfering with the internal components of the electronic device. Furthermore, the present application has two radiators through the arrangement of the first radiator 300 and the second radiator 400, thereby improving the antenna efficiency of the present application, and the polarization directions of the first radiator 300 and the second radiator 400 are arranged to be orthogonal, that is, the polarization directions of the two are perpendicular to each other. Such an arrangement can effectively reduce the mutual interference between the first radiator 300 and the second radiator 400 in the same frequency band, increase the isolation between the first radiator 300 and the second radiator 400, thereby improving the antenna efficiency, and then improving the performance of the antenna and the signal reception quality.
