[0003] Satellites often transmit and receive signals in circular polarization. In related technologies, antennas of electronic devices such as smartphones are often linearly polarized, making it difficult for electronic devices to communicate with satellites. Summary of the invention

Moreover, since the first radiator and the second radiator of the electronic device of the present application both extend mainly in the first direction, the size occupied by the electronic device in the second direction is relatively small, and the electronic device of the embodiment of the present application can also be miniaturized.

[0026] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.14 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] The present application embodiment provides an electronic device 100, which may be a smart phone, a tablet computer, or a gaming device, an augmented reality (AR) device, an automotive device, a data storage device, an audio player, a video player, a laptop computer, a desktop computing device, etc. The electronic device 100 may, but is not limited to, communicate with a satellite, and the electronic device 100 may transmit satellite signals. Please refer to Figure 1 , Figure 1 This is a schematic diagram of a first structure of an electronic device 100 provided in an embodiment of the present application. The electronic device 100 includes a first radiator 110 , a second radiator 120 , a first feed source 130 and a floor 140 .

[0028] The first radiator 110 is provided with a slot 111 extending in a first direction H1. The slot 111 enables the first radiator 110 to have a first radiating arm 112 extending in the first direction H1 along the bottom wall of the slot 111, and a second radiating arm 113 extending in a second direction H2 along the side wall of the slot 111, wherein the second direction H2 is perpendicular to the first direction H1. The second radiator 120 may be spaced apart from the first radiator 110, and the second radiator 120 extends in the first direction H1, so that the second radiator 120 may be arranged parallel to the slot 111 and the first radiating arm 112. The first feed 130 may be electrically connected to the first radiator 110, or the first feed 130 may be electrically connected to the second radiator 120, and the first feed 130 may excite the first radiator 110 to support the first wireless signal in a circularly polarized manner together with the second radiator 120 and the floor 140 in a half-wavelength resonance mode.

[0029] It is understandable that the gap 111 of the first radiator 110 may be formed inside the first radiator 110 rather than at the edge of the first radiator 110, so that the gap 111 may not be connected to the free space in the first direction H1 and the second direction H2. Figure 6 The first radiator 110 shown in the figure is an integral structure, and the gap 111 can be formed inside the first radiator 110 so that the first radiator 110 is a rectangular ring structure; for another example, as described later in this application Figure 7The first radiator 110 shown may be composed of a plurality of parts, and the plurality of parts may be spliced ​​together to form a gap 111 that is not connected to the free space. The gap 111 may include a bottom wall / top wall extending along the first direction H1, and a side wall extending along the second direction H2. The portion of the first radiator 110 along the bottom wall / top wall of the gap 111 may form a first radiating arm 112 extending along the first direction H1, and the portion of the first radiator 110 along the side wall of the gap 111 may form a second radiating arm 113 extending along the second direction H2. The first radiator 110 may include two first radiating arms 112 and two second radiating arms 113, so that the first radiator 110 may have radiating arms extending along the first direction H1 and the second direction H2.

[0030] It can be understood that the size of the slot 111 of the first radiator 110 along the second direction H2 can be much smaller than the size along the first direction H1. For example, the first size of the slot 111 of the first radiator 110 along the first direction H1 can be approximately equal to half the wavelength of the first wireless signal (the first size can be between one-third and three-quarters of the wavelength); the second size of the slot 111 of the first radiator 110 along the second direction H2 can be between one-hundredth and five-hundredth of the wavelength of the first wireless signal, and the slot 111 can be a narrow slot. Under the effect of the narrow slot, the first radiator 110 can have a longer first radiating arm 112 and a shorter second radiating arm 113, the first radiator 110 occupies a smaller space in the second direction H2, and the first radiator 110 can form a miniaturized design.

[0031] It can be understood that the slot 111 of the first radiator 110 can penetrate the first radiator 110 along the thickness direction of the first radiator 110, and the thickness direction can be the third direction, and the thickness direction or the third direction can be perpendicular to the first direction H1 and the second direction H2, so that the first radiator 110 can radiate signals outward through the slot 111, and the first radiator 110 can form a slot antenna. The so-called slot antenna refers to an antenna formed by a slot on a conductor surface, also known as a slot antenna; the typical slot 111 is in the shape of a long strip, with a length of about half a wavelength; the slot 111 can be fed by a transmission line connected across its narrow side, or by a waveguide or a resonant cavity; at this time, a radio frequency electromagnetic field is excited on the slot 111, and electromagnetic waves are radiated into space.

[0032] It is understandable that the second radiator 120 can support the first wireless signal in the form of a monopole antenna, a dipole antenna or an inverted F antenna. Of course, the second radiator 120 can also be a radiator structure of other forms, which is not limited in the embodiments of the present application. The second radiator 120 can be stacked and spaced with the first radiator 110 along the third direction, the second radiator 120 can also be stacked and spaced with the first radiator 110 along the second direction H2, and the second radiator 120 can also be spaced with the first radiator 110 along the first direction H1. The embodiments of the present application are not limited in this regard. Among them, the second radiator 120 can be electromagnetically coupled with the first radiator 110. The so-called electromagnetic coupling connection means that when an electric field is generated between two radiators, the signal on one radiator can be transmitted to the other radiator through the electric field or magnetic field, so that the two radiators can also achieve electrical signal conduction without direct contact or direct connection. When the first feed source 130 is electrically connected to the first radiator 110 or the second radiator 120 , the excitation signal provided by the first feed source 130 can be electromagnetically coupled to the other radiator, so that the first radiator 110 , the second radiator 120 and the floor 140 can jointly support the first wireless signal under the action of the first feed source 130 .

[0033] It can be understood that the floor 140 can be a common ground of the electronic device 100, the floor 140 can be a plane or structure with zero electric potential, and the floor 140 can be formed by a conductor, a printed circuit or a metal printed layer in the electronic device 100. For example, the floor 140 can be formed on a main board, a small board or other supporting board of the electronic device 100; for another example, the floor 140 can also be formed on the frame of the electronic device 100. The specific setting position of the floor 140 is not limited in the embodiment of the present application. Among them, the first radiator 110 and the second radiator 120 can be arranged on the same ground, and the distance between the first radiator 110, the second radiator 120 and the floor 140 can be at an appropriate position, so that when the first feed source 130 provides an excitation signal to one of the first radiator 110 and the second radiator 120, an induced current can be generated on the floor 140, and the induced current can excite the other radiator of the first radiator 110 and the second radiator 120 to generate a magnetic field coupling excitation, so that the first radiator 110 and the second radiator 120 can be electromagnetically coupled.

[0034] It can be understood that the first feed source 130 can be a signal source of the electronic device 100. The first feed source 130 can be electrically connected to the first radiator 110, in which case the first radiator 110 can be used as a main radiator and the second radiator 120 can be used as a parasitic radiator of the first radiator 110. The first feed source 130 can also be electrically connected to the second radiator 120, in which case the second radiator 120 can be used as a main radiator and the first radiator 110 can be used as a parasitic radiator of the second radiator 120. Among them, the first feed source 130 can convert high-frequency excitation signals or bound electromagnetic waves into radiated electromagnetic energy. For example, the first feed source 130 can provide an excitation signal to the first radiator 110 or the second radiator 120, and the excitation signal can excite the first radiator 110, the second radiator 120 and the floor 140 to jointly support the transmission of the first wireless signal in a circularly polarized manner; at the same time, the first radiator 110 and the second radiator 120 can also capture and bind electromagnetic waves in the free space and transmit them to the first feed source 130 to form a current signal, so that the first radiator 110, the second radiator 120 and the floor 140 can jointly support the reception of the first wireless signal in a circularly polarized manner.

[0035] It can be understood that the first feed source 130 can excite the first radiator 110 and the second radiator 120 to generate orthogonal resonant currents, so that the first radiator 110, the second radiator 120 and the floor 140 can form a circularly polarized radiation mode. For example, the first radiating arm 112 of the first radiator 110 includes a first end and a second end, wherein one second radiating arm 113 is connected to the first end, and the other second radiating arm 113 is connected to the second end; the first feed source 130 can excite the first radiator 110 to generate a first resonant current, and the first resonant current can form a current zero point area on the first radiating arm 112, and the first resonant current can flow from the current zero point area to the first end and the second end respectively, and flow from the first end and the second end to the two second radiating arms 113, and the resonant current components of the first resonant current on the first radiating arm 112 can offset each other; the first feed source 130 is also used to excite the second radiator 120 to generate a second resonant current, and the second resonant current flows from one end of the second radiator 120 to the other end of the second radiator 120, so that the second resonant current can be perpendicular to the component of the first resonant current on the second radiating arm 113 to achieve orthogonality.

[0036] It can be understood that the current zero point area is the weakest area of ​​the resonant current on the radiator. Since the resonant current is a periodic current, one or more current zero point areas can be formed on the radiator. On the current simulation diagram, the current zero point area is the area with the lightest color of the resonant current distribution.

[0037] The following takes the first feed source 130 electrically connected to the second radiator 120 as an example to illustrate the solution of the embodiment of the present application. Figure 1 Please also refer to Figures 2 to 4 , Figure 2 for Figure 1 A magnetic field distribution simulation diagram when the electronic device 100 supports the first wireless signal is shown. Figure 3 for Figure 1 A current distribution simulation diagram when the electronic device 100 supports the first wireless signal is shown. Figure 4 for Figure 1The electronic device 100 shown supports a circularly polarized radiation pattern when the first wireless signal is supported. When the first feed source 130 is electrically connected to the second radiator 120, the excitation signal provided by the first feed source 130 can be electromagnetically coupled to the first radiator 110, so that the first radiator 110 can generate a first resonance mode and the second radiator 120 can generate a second resonance mode, and the second resonance mode can generate a second resonance current I2 flowing along the extension direction of the second radiator 120 (i.e., the first direction H1) on the second radiator 120, that is, the second resonance mode can form a second resonance current I2 flowing along the first direction H1 on the second radiator 120. At the same time, the first resonance mode can generate a first resonance current I1 on the first radiator 110. When the first resonance mode is a half-wavelength resonance mode, the half-wavelength resonance mode can cause the first radiator 110 to generate a resonance current zero point area A1 (the weakest point of the resonance current). The resonance current zero point area A1 is approximately located near the middle of the first radiation arm 112 (for example, the distance between the midpoint of the first radiation arm 112 and the first radiation arm 112 is less than or equal to one-quarter of the length of the first radiation arm 112). The first resonance current I1 generated on the first radiator 110 by the half-wavelength resonance mode may include a resonance current component I11 flowing on the first radiation arm 112 and a resonance current component I12 flowing on the second The resonant current component I12 flows on the radiation arm 113, wherein the resonant current component I11 can flow from the resonant current zero point area A1 on the first radiator 110 toward the two ends of the first radiation arm 112 of the first radiator 110 and has a tendency to flow along the second radiation arm 113 of the first radiator 110. At this time, the resonant current I11 generated on the first radiation arm 112 of the first radiator 110 flows in opposite directions and cancels each other out. Only the resonant current component I12 flowing along the two second radiation arms 113 remains on the first radiator 110. The resonant current component I12 flows in the same direction on the two second radiation arms 113 and both flow along the first direction H1. Thus, when the first feed source 130 excites the electromagnetic coupling between the first radiator 110 and the second radiator 120, the resonant current I2 component flowing along the first direction H1 on the second radiator 120 can be orthogonal to the resonant current I12 component flowing along the second direction H2 on the two second radiation arms 113 of the first radiator 110, so that the first feed source 130 can excite the first radiator 110, the second radiator 120 and the floor 140 to jointly support the first wireless signal in a circularly polarized manner, and the electronic device 100 can achieve circularly polarized radiation. And, as Figure 4 As shown, the directivity value (Dir-Abs parameter) of the overall circular polarization of the electronic device 100 of the embodiment of the present application is approximately 6.274dBi, and the directivity value (Dir-Left parameter) of the left-hand circular polarization of the electronic device 100 is approximately 6.133dBi, and the difference between the two is not large. It can be seen that the circular polarization purity of the electronic device 100 of the embodiment of the present application is relatively high.

[0038] It can be understood that the first resonant current I1 generated by the first feed source 130 to excite the first radiator 110 can have a phase difference of ninety degrees with the second resonant current I2 generated by the first feed source 130 to excite the second radiator 120, so that the circular polarization purity of the circularly polarized radiation jointly formed by the first feed source 130 to excite the first radiator 110, the second radiator 120 and the floor 140 is higher.

[0039] It can be understood that the circular polarization of the antenna is a type of polarization of the antenna. The polarization of the antenna includes linear polarization, elliptical polarization and circular polarization. The polarization of the antenna is the polarization of the electromagnetic wave of the antenna in the direction of maximum gain. The polarization of the electromagnetic wave is the change of the electric field trajectory at a certain position over time. The electric field trajectory may be a straight line, a circle or an ellipse, so that the antenna can be linearly polarized, circularly polarized or elliptically polarized. Among them, the linear polarization of the antenna refers to the polarization of the electromagnetic wave with a fixed orientation of the electric field vector in space. When the ground is used as a reference, the direction of the electric field vector parallel to the ground is horizontal polarization, and the direction perpendicular to the ground is vertical polarization. Elliptical polarization refers to the angle between the polarization plane of the electromagnetic wave and the normal plane of the earth that changes periodically from 0 to 360 degrees, and the trajectory of the end of the electric field vector is projected as an ellipse on a plane perpendicular to the propagation direction. It is called elliptical polarization. Circular polarization refers to the characteristic that the magnitude of the electric field remains unchanged, the direction of the electric field changes with time, and the projection of the trajectory of the end of the electric field vector on a plane perpendicular to the propagation direction is a circle; circular polarization can be achieved when the horizontal component and the vertical component of the electric field have equal amplitudes and a phase difference of ninety degrees or two hundred and seventy degrees; and if the polarization plane rotates with time and is in a right-handed spiral relationship with the propagation direction of the electromagnetic wave, it is called right-handed circular polarization; conversely, if it is a left-handed spiral relationship, it is called left-handed circular polarization. When the first radiator 110 and the second radiator 120 jointly support the transmission and reception of wireless signals in a circularly polarized manner, the circularly polarized transmission and reception method can overcome the multipath effect and improve the accuracy of communication, especially can improve the communication performance between the first radiator 110 and the second radiator 120 and the communication satellite; it can also eliminate polarization distortion and improve the anti-interference performance of the electronic device 100.

[0040] It is understandable that the electronic device 100 can specially design the electrical length of the first radiator 110 so that the first radiator 110 can form a half-wavelength resonance mode and can support the first wireless signal in a circularly polarized manner together with the second radiator 120 and the floor 140. The electrical length of the radiator refers to the effective electrical length of the radiator when radiating a wireless signal, and the electrical length of the radiator can be greater than, less than or equal to its branch length. The electrical length of the radiator can be changed by changing the grounding point of the radiator, the structure and parameters of the electrically connected adjustment circuit, the tuning circuit, and the matching circuit. The electrical length of the radiator can be associated with the frequency and mode of the wireless signal supported by the radiator; when the electrical length of the radiator is longer, the radiator can support wireless signals with lower frequencies; when the electrical length of the radiator is shorter, the radiator can support wireless signals with higher frequencies. When the electrical length of the radiator is one-quarter of the wavelength of the wireless signal it supports, the radiator can form a quarter-wavelength resonance mode; when the electrical length of the radiator is half of the wavelength of the wireless signal it supports, the radiator can form a half-wavelength resonance mode.

[0041] It is understandable that the electronic device 100 can design the branch length (length along the first direction H1) of the first radiator 110 to be approximately half the wavelength of the first wireless signal, so that the first radiator 110 can form a half-wavelength resonance mode under the excitation of the first feed source 130. The electronic device 100 can also design a load circuit electrically connected to the first radiator 110, and the electrical length of the first radiator 110 adjusted by the load circuit can be half the wavelength of the first wireless signal through the branch length of the first radiator 110 along the first direction H1 and the impedance value of the load circuit. The specific manner in which the first radiator 110 forms a half-wavelength resonance mode is not limited in the embodiment of the present application.

[0042] In the electronic device 100 of the embodiment of the present application, the gap 111 on the first radiator 110 can enable the first radiator 110 to have a first radiating arm 112 extending along the first direction H1 and a second radiating arm 113 extending in the second direction H2; the second radiator 120 arranged along the second direction H2 is spaced apart from the first radiator 110 and can be electromagnetically coupled; when the first feed source 130 feeds an excitation signal to the first radiator 110 or the second radiator 120, the excitation signal can excite the second radiator 120 to generate a resonant current I2 flowing along the first direction H1; the excitation signal can also excite the first radiator 110 to generate a half-wavelength resonant mode, in which the resonant current I11 on the first radiating arm 112 of the first radiator 110 can flow from the resonant current zero point area A1 toward both ends The resonant current I12 on the second radiating arm 113 of the first radiator 110 can flow along the second direction H2, and the resonant current I12 flowing along the second direction H2 on the second radiating arm 113 can be orthogonally arranged with the resonant current I2 flowing along the first direction H1 on the second radiator 120, so that the first radiator 110, the second radiator 120 and the floor 140 can support the first wireless signal in a circularly polarized manner; and, since the resonant current I11 on the first radiating arm 112 of the first radiator 110 cancels each other, the circular polarization purity formed by the first radiator 110 and the second radiator 120 is higher, the electronic device 100 has better circular polarization performance, the electronic device 100 can be more suitable for use scenarios with satellite communications, and the radiation performance of the electronic device 100 with satellite communications can be improved. Furthermore, since the first radiator 110 and the second radiator 120 of the electronic device 100 of the present application mainly extend along the first direction H1, the size occupied by the electronic device 100 in the second direction H2 is relatively small. Compared with the solution in the related art that requires separate design of the radiator along the first direction H1 and the radiator along the second direction H2, the electronic device 100 of the embodiment of the present application can also achieve a miniaturized design.

[0043] The electronic device 100 of the embodiment of the present application can be either a satellite antenna or a global positioning system (GPS) antenna. Considering that GPS communication often uses right-hand circular polarization to locate the GPS antenna, when the electronic device 100 of the embodiment of the present application is used as a GPS antenna, the relative positions of the first radiator 110 and the second radiator 120 can be designed so that the electronic device 100 has better right-hand circular polarization performance.

[0044] For example, please refer to Figures 1 to 4 , Figures 1 to 4The electronic device 100 shown has a better left-hand circular polarization radiation performance. If the electronic device 100 is required to have a better right-hand circular polarization radiation performance, the central axis L0 of the electronic device 100 extending along the second direction H2 can be used as the symmetry axis. Figure 1 The electronic device 100 shown is mirrored. Figure 5 As shown, Figure 5 A second structural diagram of the electronic device 100 provided in an embodiment of the present application is shown in FIG. Figure 5 The electronic device 100 is shown with Figure 1 The electronic device 100 shown is mirror-imaged along the axis of symmetry. Figure 5 The electronic device 100 shown may have better right-hand circular polarization performance.

[0045] It should be noted that the polarization mode and polarization direction of the antenna are different from the radiation direction. The radiation direction of the antenna is the direction in which the main beam of the antenna is directed. For example, in the embodiment of the present application, when the first radiator 110 and the second radiator 120 jointly support the first wireless signal, the first radiator 110 and the second radiator 120 have two main beams, both of which are perpendicular to the floor 140 and radiate in different directions, such as Figure 4 As shown, one main beam is directed from the floor 140 toward the direction where the reference surface is located (for example, toward the direction where the display surface is located), and another main beam is directed from the floor 140 toward the direction away from the reference surface (for example, toward the direction of the rear shell, and the beam is Figure 3 (not shown), the electronic device 100 may have a double water drop type radiation direction.

[0046] The polarization mode and polarization direction of the antenna affect the form of the main beam of the antenna propagating in space. Generally, when the main beam is linearly polarized, the linearly polarized electromagnetic wave can be received by another antenna that supports linear polarization; when the main beam is circularly polarized, the circularly polarized electromagnetic wave can be received by another antenna that supports circular polarization. Therefore, when the polarization forms supported by the two antennas are the same, the two antennas are more likely to achieve better transmission performance. Furthermore, the polarization direction is the direction of the polarization form of the antenna. Linear polarization can have ±45° linear polarization direction, horizontal polarization direction, vertical polarization direction and other polarization directions; circular polarization can have left-hand circular polarization direction and right-hand circular polarization direction. Generally speaking, when the polarization directions of the two antennas are the same, the two antennas are more likely to achieve better transmission performance. If the polarization directions of the two antennas are perpendicular to each other, the two antennas basically cannot achieve signal transmission. For example, when a satellite antenna transmits a signal in a left-hand circular polarization direction, the electronic device 100 of the present application preferably also receives the signal in a left-hand circular polarization direction. If the electronic device 100 of the present application receives the signal in a right-hand circular polarization direction, the signal transmitted by the satellite antenna cannot be received. For another example, when a GPS antenna transmits a GPS signal in a right-hand circular polarization direction, when the electronic device 100 of the embodiment of the present application receives the GPS antenna in a right-hand circular polarization direction, the electronic device 100 can have very good GPS performance.

[0047] It should be noted that in the related art, in the field of electronic devices such as smart phones, tablet computers, desktop computers and other devices, the antennas installed on the electronic devices are often linearly polarized antennas, while satellites often transmit and receive signals in the form of circular polarization, which makes the linearly polarized antennas on the electronic devices in the related art unable to receive circularly polarized satellite signals well. However, the electronic device 100 of the present application can transmit and receive signals in a circularly polarized manner, and the electronic device 100 of the present application can communicate better with the satellite antenna; in addition, the main beam direction of the first radiator 110 and the second radiator 120 of the embodiment of the present application when jointly supporting the first wireless signal is a fixed direction perpendicular to the floor 140, and the beam of the electronic device 100 of the present application has the characteristics of directional high gain, so the electronic device 100 of the present application is very suitable for satellite (including GPS satellite) communication.

[0048] Please refer again to Figures 1 to 5 Please also refer to Figure 6 , Figure 6 This is a schematic diagram of a first structure of the first radiator 110 of the electronic device 100 provided in an embodiment of the present application. The first radiator 110 can form a half-wavelength resonance mode in the form of a loop antenna and support a first wireless signal.

[0049] The slot 111 of the first radiator 110 may be formed inside the first radiator 110, so that the first radiator 110 may be a ring radiator structure with two ends connected. Under the action of the slot 111, the first radiator 110 may have two first radiating arms 112 extending along the first direction H1 and two second radiating arms 113 extending along the second direction H2. When the first feed source 130 excites the first radiator 110 and the second radiator 120 to electromagnetically couple, the resonant current I11 flowing on the first radiating arm 112 may cancel each other, and the first radiator 110 may only have a resonant current I12 component extending along the second direction H2, and the resonant current I12 component and the second resonant current I2 on the second radiator 120 along the first direction H1 may be orthogonally arranged, so that the first radiator 110 and the second radiator 120 can jointly support the first wireless signal in a circularly polarized manner.

[0050] It can be understood that the first radiator 110 can be, but is not limited to, a whole radiator formed with the gap 111 by cutting, etching, etc., and the first radiator 110 can be an integral structure.

[0051] It is understandable that when the first radiator 110 is a ring radiator structure with two ends connected, the first radiator 110 can be disposed at any suitable position of the electronic device 100. At the same time, the second radiator 120 can be stacked and spaced apart from the first radiator 110 along the first direction H1, the second direction H2 or the third direction. The embodiment of the present application does not further limit the arrangement positions of the first radiator 110 and the second radiator 120.

[0052] It can be understood that the first distance between the second radiator 120 and the first radiating arm 112 of the first radiator 110 along the second direction H2 can be within the first preset distance range, so that the maximum current amplitude when the first radiator 110 supports the first wireless signal is equal to the maximum current amplitude when the second radiator 120 supports the first wireless signal. At this time, the interval between the first radiator 110 and the second radiator 120 is appropriate, and the coupling strength when the two are electromagnetically coupled is better.

[0053] It can be understood that the second distance between the second radiator 120 and the first radiator 110 along the first direction H1 is within the second preset distance range, so that the difference between the phase when the first radiator 110 supports the first wireless signal to reach the maximum current amplitude and the phase when the second radiator 120 supports the first wireless signal to reach the maximum current amplitude is ninety degrees, at which time the purity of the circular polarization radiation formed by the first radiator 110, the second radiator 120 and the floor 140 is higher, and the circular polarization performance of the electronic device 100 is better. Among them, the second distance can be the distance between the midpoint of the second radiator 120 and the midpoint of the first radiating arm 112 along the first direction H1, and the second distance can represent the gap between the second radiator 120 and the first radiating arm 112 along the first direction H1.

[0054] It is understandable that when the first feed source 130 is electrically connected to the first radiator 110, the first feed source 130 can be electrically connected to the first radiating arm 112 of the first radiator 110, so that the first radiator 110 is more easily excited to generate a half-wavelength resonance mode. Of course, the first feed source 130 can also be electrically connected to other areas of the first radiator 110, for example but not limited to, the first feed source 130 can be fed by a transmission line spanning the narrow side of the slot 111 of the first radiator 110, and the first feed source 130 can also be fed by a waveguide or a resonant cavity. The embodiment of the present application does not limit the specific feeding method of the first feed source 130.

[0055] The first radiator 110 of the embodiment of the present application is a ring radiator structure with two ends connected. The first radiator 110 with a ring structure is more likely to excite a half-wavelength resonance mode, so that the electronic device 100 has better circular polarization performance. At the same time, the first radiator 110 can be an integral structure, which can not only improve the structural strength of the first radiator 110, but also make the setting position of the first radiator 110 more flexible.

[0056] Please combine Figures 1 to 5 Please also refer to Figure 7 , Figure 7 The second structural diagram of the first radiator 110 of the electronic device 100 provided in the embodiment of the present application. The electronic device 100 may further include a radiation branch 150 .

[0057] The floor 140 may include an edge S1 extending along the first direction H1, and the edge S1 may include a first area 142 and a second area 143 disposed at intervals. The radiation branch 150 may be disposed at intervals from the first edge S1 of the floor 140, one end of the radiation branch 150 may be connected to the first area 142 of the first edge S1 and grounded, the other end of the radiation branch 150 may be connected to the second area 143 of the edge S1 and grounded, and a gap 111 may be formed between the radiation branch 150 and the edge S1, so that the first radiator 110 may include the floor 140 and the radiation branch 150.

[0058] It can be understood that when the second radiator 120 is grounded and the first feed source 130 is electrically connected to the second radiator 120, the second radiator 120 can generate a second resonant current I2 under the excitation of the first feed source 130. At the same time, an induced current of equal intensity can be generated on the floor 140. The induced current can directly excite the floor 140 and the radiation branch 150 to form a resonant mode, thereby realizing the electromagnetic coupling connection between the first radiator 110 and the second radiator 120.

[0059] It is understandable that the portion between the first area 142 and the second area 143 of the edge S1 of the floor 140 may be flush with other portions of the edge S1 . In this case, the radiating branch 150 may be at a certain distance from the edge S1 so that a gap 111 may be formed therebetween.

[0060] It can be understood that a notch 141 may be formed on the edge S1 of the floor 140, the bottom wall of the notch 141 may extend along the first direction H1, and the side walls of the notch 141 may extend along the second direction H2, and the area where the side walls of the notch 141 are connected to the bottom wall may be the first area 142 and the second area 143 of the edge S1, and at this time, the portion between the first area 142 and the second area 143 of the edge S1 may not be flush with other portions of the edge S1. One end of the radiating branch 150 may be connected to one side wall of the notch 141, and the other end of the radiating branch 150 may be connected to the other side wall of the notch 141, so that the radiating branch 150 may extend along the first direction H1. The first radiator 110 may include the floor 140 and the radiating branches 150. The area enclosed by the radiating branches 150, the two side walls of the notch 141 and the bottom wall of the notch 141 may form the gap 111 of the first radiator 110. The radiating branches 150 may form the first radiating arms 112 of the first radiator 110 extending along the first direction H1. The two side walls of the notch 141 may form the second radiating arms 113 of the first radiator 110 extending along the second direction H2. It should be noted that the above is only an exemplary description of the floor 140 and the radiating branches 150 forming the first radiator 110. Other solutions that can make the floor 140 and the radiating branches 150 form the first radiator 110 are all within the protection scope of the embodiments of the present application.

[0061] It is understood that the floor 140 may be, but is not limited to, a rectangular structure. For example, the floor 140 may include a side extending along the first direction H1 and a side extending along the second direction H2. The notch 141 on the floor 140 may be formed on the side extending along the first direction H1, and the radiation branch 150 may be arranged relative to the side of the floor 140 extending along the first direction H1.

[0062] It can be understood that when the two ends of the radiation branch 150 are respectively connected to the two side walls of the gap 141 of the floor 140, the radiation branch 150 can be connected to the floor 140 and realize electrical connection. When the first feed source 130 feeds an excitation signal to the first radiator 110 or the second radiator 120, the radiation branch 150 can form a half-wavelength resonance mode. The first resonant current generated by the excitation signal can form a resonant current zero point area on the radiation branch 150. The resonant current can flow from the resonant current zero point area A1 toward the two ends of the radiation branch 150 and flow into the floor 140 along the two side walls of the gap 141 to form a return current path. Among them, the resonant current components flowing on the radiating branch 150 can cancel each other out due to their opposite flow directions, and the first resonant current can have a remaining resonant current component flowing from the two ends of the radiating branch 150 to the floor 140. This resonant current component can be set orthogonally to the resonant current flowing on the second radiator 120. Therefore, the floor 140, the radiating branch 150 and the second radiator 120 can jointly support the first wireless signal in a circularly polarized manner under the excitation of the first feed source 130.

[0063] It is understandable that the second radiator 120 can be stacked and spaced with the radiation branch 150 of the first radiator 110 along the second direction H2. For example, the second radiator 120 can be located on the side of the notch 141 of the floor 140 away from the radiation branch 150. In this case, the second radiator 120 and the first radiator 110 can be arranged in the second direction H2 of the electronic device 100, and the two are not likely to occupy additional space in the first direction H1 of the electronic device 100, which is conducive to the miniaturization design of the electronic device 100.

[0064] It can be understood that the third distance between the second radiator 120 and the radiation branch 150 of the first radiator 110 along the second direction H2 is within the first preset distance range, so that the maximum current amplitude when the first radiator 110 supports the first wireless signal is equal to the maximum current amplitude when the second radiator 120 supports the first wireless signal. At this time, the interval between the radiation branch 150 of the first radiator 110 and the second radiator 120 is appropriate, and the coupling strength of the two when they are electromagnetically coupled is better.

[0065] It can be understood that the fourth distance between the second radiator 120 and the radiation branch 150 of the first radiator 110 along the first direction H1 is within the second preset distance range, so that the difference between the phase when the first radiator 110 supports the first wireless signal to reach the maximum current amplitude and the phase when the second radiator 120 supports the first wireless signal to reach the maximum current amplitude is ninety degrees, at which time the purity of the circular polarization radiation formed by the first radiator 110, the second radiator 120 and the floor 140 is higher, and the circular polarization performance of the electronic device 100 is better. Among them, the fourth distance can be the distance between the midpoint of the second radiator 120 and the midpoint of the radiation branch 150 along the first direction H1, and the fourth distance can represent the gap between the second radiator 120 and the radiation branch 150 along the first direction H1.

[0066] In the electronic device 100 of the embodiment of the present application, the floor 140 and the radiating branch 150 jointly form the first radiator 110, and the first radiator 110 reuses part of the area of ​​the floor 140, so as to realize the miniaturized design of the electronic device 100; at the same time, by forming a notch 141 on the floor 140 to form a slot antenna together with the radiating branch 150, the resonant current on the radiating branch 150 can flow along the side wall edge of the notch 141 to the floor 140 to form a resonant current path along the second direction H2, and the length of the resonant current path is not limited to the length of the side wall of the notch 141, and the resonant current path can flow along the floor 140 and have a longer current path, so that the longer resonant current path along the second direction H2 can also more easily form circularly polarized radiation with the second radiator 120, and the electronic device 100 has better circular polarization performance.

[0067] Please refer again to Figures 1 to 7 The distance between the strong point of the resonance current when the first radiator 110 supports the first wireless signal and the strong point of the resonance current when the second radiator 120 supports the first wireless signal is one quarter of the corresponding wavelength of the first wireless signal.

[0068] It can be understood that the strong point of resonant current can be the area where the current intensity of the resonant current generated by the resonant mode exciting the radiator is the largest. Since the resonant current is a periodic current, multiple strong current points can often be formed on the radiator. From the current simulation diagram, one or more areas with the darkest current distribution color are often the strong points of the resonant current of the resonant mode.

[0069] It can be understood that a strong resonance current point can be formed on each of the first radiator 110 and the second radiator 120, and the distance between the strong resonance current point formed by the first radiator 110 and the strong resonance current point formed by the second radiator 120 can be the distance between the two strong resonance current points along the first direction H1. Figure 1As shown, the first radiator 110 and the second radiator 120 can be staggered along the first direction H1, and at least one end of the two radiators are not aligned, so that the distance between the strong points of the resonant current of the first radiator 110 and the second radiator 120 is one quarter of the corresponding wavelength of the first wireless signal.

[0070] In the electronic device 100 of the embodiment of the present application, the distance between the strong point of the resonance current when the first radiator 110 supports the first wireless signal and the strong point of the resonance current when the second radiator 120 supports the first wireless signal is one quarter of the corresponding wavelength of the first wireless signal. At this time, the phase difference when the resonance current amplitude reaches the maximum when the first radiator 110 and the second radiator 120 support the first wireless signal can be ninety degrees, and the circular polarization performance of the first wireless signal formed by the first radiator 110 and the second radiator 120 is better.

[0071] Please refer again to Figures 1 to 7 , the first feed source 130 may be as follows Figures 1 to 7 As shown, the first feed source 130 is electrically connected to the second radiator 120, and can excite the second radiator 120 to generate a quarter-wavelength resonance mode, and together with the first radiator 110 generating a half-wavelength resonance mode, and the floor 140, support the first wireless signal in a circularly polarized form.

[0072] It can be understood that the second radiator 120 may include a free end 121 and a ground end 122, the free end 121 and the ground end 122 may be two ends of the second radiator 120, the ground end 122 may be electrically connected to the floor 140 to achieve grounding, and the free end 121 may be suspended relative to the floor 140. The first feed source 130 may be electrically connected between the free end 121 and the ground end 122 of the second radiator 120, and the first feed source 130 may excite the second radiator 120 to generate a second resonant current I2 flowing from the ground end 122 toward the free end 121, and the second resonant current I2 may flow along the first direction H1 when flowing on the second radiator 120, so as to be orthogonal to the resonant current I12 in the second direction H2 flowing on the second radiation arm 113 (the side wall of the notch 141) of the first radiator 110, so that the first feed source 130 may excite the first radiator 110, the second radiator 120 and the floor 140 to form circularly polarized radiation.

[0073] It can be understood that the electrical length of the second radiator 120 can be one quarter of the wavelength corresponding to the first wireless signal, so that the second radiator 120 can more easily excite a quarter-wavelength resonant mode. At this time, the electrical length of the second radiator 120 can be smaller than the electrical length of the first radiator 110, and the volume of the second radiator 120 is smaller. When the second radiator 120 and the first radiator 110 are stacked along the second direction H2 or the third direction, the second radiator 120 is not likely to occupy additional space in the first direction H1 of the electronic device 100, and the miniaturization design of the electronic device 100 can be achieved. In addition, the second radiator 120 with a smaller electrical length is more likely to be staggered with the first radiator 110 so that the distance between the strong point of the resonant current when the first radiator 110 supports the first wireless signal and the strong point of the resonant current when the second radiator 120 supports the first wireless signal is one quarter of the wavelength corresponding to the first wireless signal.

[0074] It should be noted that the electrical length of the second radiator 120 may also be other lengths. For example, but not limited to, the electrical length of the second radiator 120 may be one-half or three-quarters of the wavelength corresponding to the first wireless signal. The embodiments of the present application do not limit the electrical length of the second radiator 120. Any scheme that can stimulate the second radiator 120 to form a resonant current flowing along the first direction H1 is within the protection scope of the embodiments of the present application.

[0075] The second radiator 120 of the embodiment of the present application can generate a quarter-wavelength resonance mode under the excitation of the first feed source 130, and the resonance current excited on the second radiator 120 is more likely to flow along the first direction H1, so that the second radiator 120 and the first radiator 110 can have better circular polarization performance after cooperation with each other.

[0076] Among them, please refer to Figure 8 , Figure 8 This is a third structural diagram of the electronic device 100 provided in an embodiment of the present application. The first feed source 130 may also be electrically connected to the first radiator 110 .

[0077] The first feed 130 may be electrically connected to the first radiation arm 112 of the first radiator 110 extending along the first direction H1. When the first radiator 110 is a ring radiator structure with two ends connected, the first feed 130 may be electrically connected to the radiation area of ​​the ring radiator adapted to the top wall / bottom wall of the slot 111. When the first radiator 110 includes a floor 140 and a radiation branch 150, the first feed 130 may be electrically connected to the radiation branch 150.

[0078] It can be understood that when the first feed source 130 is electrically connected to the first radiator 110, the second radiator 120 can be used as a parasitic branch of the first radiator 110. At this time, the second radiator 120 can be suspended relative to the floor 140, and the second radiator 120 can be ungrounded. The resonant current generated on the second radiator 120 electromagnetically coupled with the first radiator 110 can flow along the extension direction of the second radiator 120, so that the second radiator 120 is more likely to form circularly polarized radiation with the first radiator 110 and the floor 140. Of course, it should be noted that the second radiator 120 can also be grounded, and the embodiment of the present application does not limit the specific structure of the second radiator 120.

[0079] The first feed source 130 of the embodiment of the present application is electrically connected to the first radiator 110 . The first feed source 130 can more easily excite the first radiator 110 to form a half-wavelength resonance mode, and the radiation performance of the first radiator 110 is better.

[0080] Among them, please refer to Fig. 9 , Fig. 9 This is a fourth structural diagram of the electronic device 100 provided in the embodiment of the present application. When the first radiator 110 includes a base 140 and a radiating branch 150 , the electronic device 100 may further include a second feed source 160 and a switching circuit 170 .

[0081] The second feed source 160 can be directly or indirectly electrically connected to the radiating branch 150, and the first switching end of the switching circuit 170 can be electrically connected to the radiating branch 150. For example, a first electrical connection point can be set between the free end 121 and the grounding end 122 of the radiating branch 150, and the first switching end of the switching circuit 170 can be electrically connected to the electrical connection point. The second switching end of the switching circuit 170 can be electrically connected to the floor 140 to achieve grounding. Among them, the switching circuit 170 can control the first switching end and the second switching end to disconnect, so that the radiating branch 150 supports the first wireless signal under the stimulation of the first feed source 130; the switching circuit 170 is also used to control the first switching end and the second switching end to be turned on, so that the radiating branch 150 is grounded, and the radiating branch 150 is used to support the second wireless signal under the stimulation of the second feed source 160.

[0082] It can be understood that when the switching circuit 170 controls the first switching end and the second switching end to disconnect, the radiation branch 150 cannot return to the ground through the switching circuit 170, and the resonant current generated by the first feed source 130 to stimulate the first radiator 110 will still flow from the resonant current zero point area A1 on the first radiator 110 to the two ends of the first radiator 110 and flow to the floor 140 through the side wall of the notch 141 of the floor 140 and form a half-wavelength resonant mode. At this time, the first feed source 130 can stimulate the first radiator 110 to support the first wireless signal.

[0083] It can be understood that when the switching circuit 170 controls the first switching end and the second switching end to be turned on, the radiating branch 150 can return to the ground through the switching circuit 170, and the resonant current generated by the second radiator 120 stimulated by the second feed source 160 can flow on the radiating branch 150 and return to the ground from the switching circuit 170. At this time, the second feed source 160 can stimulate the radiating branch 150 to support the second wireless signal, and the radiating branch 150 can achieve multiplexing.

[0084] It can be understood that the switching circuit 170 can be but is not limited to a switching switch, a passband circuit, a band-stop circuit, etc. Any structure that can disconnect the two ends of the switching circuit 170 so that the first radiator 110 supports the first wireless signal, and connect the two ends of the switching circuit 170 so that the first radiator 110 supports the second wireless signal is within the protection scope of the embodiments of the present application.

[0085] It is understandable that the excitation signal provided by the second feed source 160 may be different from the excitation signal provided by the first feed source 130, so that the second wireless signal may be different from the first wireless signal. For example, the frequency band range of the first wireless signal may be spaced apart from the frequency band range of the second wireless signal; or, the frequency band range of the first wireless signal and the frequency band range of the second wireless signal partially overlap in the spectrum, but the center frequencies of the two spectra may be different. Exemplarily, when the first wireless signal is a satellite signal / GPS signal, the second wireless signal may be, but is not limited to, a wireless fidelity (Wireless Fidelity, referred to as Wi-Fi) signal, a third generation mobile communication technology (3rd-Generation, referred to as 3G), a fourth generation mobile communication technology (4th-Generation, referred to as 4G), a fifth generation mobile communication technology (5th-Generation, referred to as 5G), a near field communication (Nearfield communication, referred to as NFC) signal, a Bluetooth (Blue tooth, referred to as BT) signal, a near field communication (NearField Communication, referred to as NFC) signal, an ultra-wideband communication (Ultra Wide Band, referred to as UWB) signal, etc. The embodiment of the present application does not limit the first wireless signal and the second wireless signal.

[0086] It is understandable that the second feed 160 can be a separate feed excitation device from the first feed 130. In this case, the first feed 130 and the second feed 160 excite to generate respective excitation signals. Of course, the second feed 160 can be the same feed excitation device as the first feed 130. For example, the electronic device 100 can include a radio frequency transceiver, which can be used as the first feed 130 to provide an excitation signal to the first radiator 110, and the radio frequency transceiver can also be used as the second feed 160 to provide a second excitation signal to the first radiator 110. In this case, the electronic device 100 can also include a combiner, a duplexer and other devices to avoid crosstalk between the excitation signal and the second excitation signal.

[0087] In the electronic device 100 of the embodiment of the present application, the radiating branch 150 of the first radiator 110 can support the first wireless signal under the action of the first feed source 130 and the switching circuit 170, and the radiating branch 150 can also support the second wireless signal under the action of the second feed source 160 and the switching circuit 170. The radiating branch 150 can be multiplexed, which can not only realize the miniaturized design of the electronic device 100, but also increase the communication function of the electronic device 100.

[0088] Based on the structure of the electronic device 100, please refer to Fig.10 , Fig.10 This is a fifth structural diagram of the electronic device 100 provided in an embodiment of the present application. The electronic device 100 may further include a display screen 20 , a middle frame 30 , a circuit board 40 , a battery 50 and a rear housing 60 .

[0089] The display screen 20 can be mounted on the middle frame 30 and connected to the rear case 60 through the middle frame 30 to form a display surface of the electronic device 100. The display screen 20 can be used to display information such as images and texts. The display screen 20 can be a display device of the type of an organic light-emitting diode (OLED) display device or an organic light-emitting diode (OLED) display.

[0090] The middle frame 30 may include a frame 31 and a middle plate 32, and the middle plate 32 may provide support for the electronic components or electronic devices in the electronic device 100. The frame 31 is connected to the edge of the middle plate 32 and protrudes from the middle plate 32. The frame 31 and the middle plate 32 form a containing space, and the electronic components and electronic devices in the electronic device 100 may be installed and fixed in the containing space.

[0091] The circuit board 40 can be mounted on the middle frame 30. The circuit board 40 can be the mainboard of the electronic device 100. Among them, the circuit board 40 can be integrated with one, two or more electronic devices such as a microphone, a speaker, a receiver, a headphone jack, a universal serial bus interface (USB interface), a camera assembly, a distance sensor, an environmental sensor, a gyroscope and a processor. Among them, the display screen 20 can be electrically connected to the circuit board 40 to control the display of the display screen 20 through the processor on the circuit board 40. It can be understood that the first feed 130 and the second feed 160 can be arranged on the circuit board 40. Of course, the first feed 130 and the second feed 160 can also be arranged on other carrier boards of the electronic device 100. The embodiment of the present application does not limit the specific setting position of the first feed 130 and the second feed 160.

[0092] The battery 50 may be mounted on the middle frame 30. At the same time, the battery 50 is electrically connected to the circuit board 40 so that the battery 50 can power the electronic device 100. A power management circuit may be provided on the circuit board 40. The power management circuit is used to distribute the voltage provided by the battery 50 to various electronic devices in the electronic device 100.

[0093] The rear case 60 may be connected to the middle frame 30, such as the frame 31. The rear case 60, the middle frame 30 and the display screen 20 may seal the electronic devices and functional components of the electronic device 100 inside the electronic device 100 to protect the electronic devices and functional components of the electronic device 100.

[0094] It is understandable that when the middle plate 32 of the middle frame 30 is made of a conductive material, part or all of the middle plate 32 can form the floor 140 of the electronic device 100. At this time, the middle plate 32 can not only carry the devices of the electronic device 100 but also serve as a grounding device. The middle plate 32 can be reused, and the electronic device 100 and the electronic device 100 can be miniaturized. Of course, the floor 140 can also be set at other positions of the electronic device 100. For example, but not limited to, the floor 140 can be formed on structures such as the circuit board 40 and the back shell 60, or the floor 140 can also be set on the electronic device 100 and stacked with the circuit board 40, the middle plate 32, and the back shell 60. The specific structure of the floor 140 is not limited in the embodiment of the present application.

[0095] Among them, please refer to Fig.11 , Fig.11 This is a sixth structural diagram of the electronic device 100 provided in an embodiment of the present application. When the first radiator 110 of the electronic device 100 includes a floor 140 and a radiation branch 150 , the middle plate 32 of the electronic device 100 may be the floor 140 of the electronic device 100 , and the radiation branch 150 of the electronic device 100 may be formed on the frame 31 of the electronic device 100 .

[0096] like Fig.11 As shown, a notch 141 may be formed at the edge of the floor 140, and the notch 141 allows a gap 111 to exist between the floor 140 and the frame 31. The preset area on the frame 31 may be a conductor structure and form a radiation branch 150, one end of which may be connected to one side wall of the notch 141, and the other end of which may be connected to the other side wall of the notch 141, so that a part of the frame 31 and the floor 140 may together form the first radiator 110 of the electronic device 100.

[0097] It is understandable that grounding branches can be provided at both ends of the radiation branch 150 of the frame 31 to connect to the side walls of the notch 141 of the floor 140. The grounding branch can be, but is not limited to, a grounding spring, a grounding pad, or other structures.

[0098] It is understandable that when the first radiator 110 reuses the frame 31 of the electronic device 100 as the radiation branch 150, the first radiator 110 can be a radiator structure in the form of a slot frame antenna. At this time, the second radiator 120 can be, but is not limited to, a radiator structure in the form of a flexible circuit board (FPC), a radiator structure in the form of a laser direct structuring (LDS), a radiator structure in the form of a bracket antenna, etc. The embodiment of the present application does not limit the specific structures of the first radiator 110 and the second radiator 120.

[0099] The first radiator 110 of the embodiment of the present application utilizes the middle plate 32 of the electronic device 100 as the floor 140 and utilizes the frame 31 of the electronic device 100 as the radiation branch 150. The middle plate 32 and the frame 31 of the electronic device 100 can be reused, which can further realize the electronic device 100 and the miniaturized design of the electronic device 100.

[0100] Among them, Fig.11 As shown, the electronic device 100 may include a first frame 311, a second frame 312, a third frame 313 and a fourth frame 314 connected in sequence, the first frame 311 and the third frame 313 are arranged opposite to each other, the second frame 312 and the fourth frame 314 are arranged opposite to each other, and the second frame 312 or the fourth frame 314 may be arranged between the first frame 311 and the third frame 313 and be bent and connected to the first frame 311 and the third frame 313 respectively. Among them, the length of the first frame 311 and the third frame 313 may be greater than the length of the second frame 312 or the fourth frame 314, so that the first frame 311 and the third frame 313 may be the long frame 31 of the electronic device 100, and the second frame 312 and the fourth frame 314 may be the short frame 31 of the electronic device 100.

[0101] It can be understood that the first radiator 110, the second radiator 120 and the first feed source 130 of the electronic device 100 form a group of antenna structures 101, and each group of antenna structures 101 can be arranged relative to any frame 31 of the electronic device 100. For example, Fig.11 As shown, the antenna structure 101 can be arranged relative to the bottom frame 31-second frame 312 of the electronic device 100. Of course, the antenna structure 101 can also be arranged relative to other frames 31 of the electronic device 100. For example, when the first wireless signal supported by the antenna structure 101 is a GPS signal, the antenna structure 101 can also be arranged relative to the top frame 31-fourth frame 314 of the electronic device 100, so that the electronic device 100 can receive the GPS signal. For another example, Fig.12 As shown, Fig.12 This is a seventh structural diagram of the electronic device 100 provided in an embodiment of the present application. The antenna structure 101 can also be arranged relative to the first frame 311 or the third frame 313, so that the antenna structure 101 can be arranged relative to the long frame 31 of the electronic device 100. In this case, Fig.13 As shown, Fig.13 for Fig.12 A circularly polarized radiation pattern of the electronic device 100 is shown. The antenna structure 101 is arranged relative to the long frame 31 to prevent the user from holding the antenna and affecting the antenna performance. At this time, the electronic device 100 can also generate good circularly polarized radiation.

[0102] It is understandable that the antenna structure 101 is arranged relative to the frame 31 of the electronic device 100, which may mean that the extension direction of the antenna structure 101 is the same as the extension direction of the frame 31, and the distance between the antenna structure 101 and the frame 31 is small. Alternatively, when the first radiator 110 of the antenna structure 101 includes the floor 140 and the radiation branch 150, the antenna structure 101 is arranged relative to the frame 31 of the electronic device 100, which may mean that the radiation branch 150 is formed on the frame 31. The embodiment of the present application does not limit the specific location of the antenna structure 101.

[0103] Among them, please refer to Fig.14 , Fig.14 The eighth structural diagram of the electronic device 100 provided in the embodiment of the present application. When the first radiator 110, the second radiator 120 and the first feed source 130 of the electronic device 100 form a group of antenna structures 101, the electronic device 100 may include two groups of antenna structures 101, and the two groups of antenna structures 101 may be symmetrically arranged about the center point of the electronic device 100.

[0104] For example, Fig.14As shown, when one group of antenna structures 101 is arranged relative to the first frame 311 of the electronic device 100, another group of antenna structures 101 can be arranged relative to the third frame 313 of the electronic device 100. For another example, when one group of antenna structures 101 is arranged relative to the second frame 312 of the electronic device 100, another group of antenna structures 101 can be arranged relative to the fourth frame 314 of the electronic device 100.

[0105] The two groups of antenna structures 101 in the embodiment of the present application are symmetrically arranged about the center point O1 of the electronic device 100. The two groups of antenna structures 101 are not easily held by the user's hands at the same time, and the antenna radiation performance of the electronic device 100 is better.

[0106] It should be noted that the multiple antenna structures 101 included in the electronic device 100 may also be arranged at other positions of the electronic device 100, and the embodiment of the present application does not limit the specific arrangement positions of the multiple antenna structures 101 of the electronic device 100.

[0107] It should be noted that the above is only an exemplary description of the electronic device 100 of the embodiment of the present application. The electronic device 10 may also include other structures, such as but not limited to an acoustic-to-electric conversion device, a camera device, etc., and the embodiment of the present application does not limit this.

[0108] In the description of this application, it should be understood that terms such as "first" and "second" are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
