[0028] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.15 , 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.

[0029] The present application provides an electronic device 10 and an antenna device 100. The electronic device 10 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 antenna device 100 may communicate with a satellite, but is not limited to communicating with a satellite. The antenna device 100 may transmit satellite signals. Please refer to Figure 1 , Figure 1 The first structural diagram of the electronic device 10 provided in the embodiment of the present application includes an antenna device 100, a signal source 140 and a floor 150. The antenna device 100 includes a first radiator 110, a second radiator 120 and a third radiator 130.

[0030] The first radiator 110 may include a first end 111, a second end 112, and a grounding point 113 disposed between the first end 111 and the second end 112. The grounding point 113 may divide the first radiator 110 into two parts. The radiating structure between the first end 111 and the grounding point 113 of the first radiator 110 may form a first radiating section 115, and the radiating structure between the second end 112 and the grounding point 113 may form a second radiating section 116. Thus, the first radiator 110 may include a first radiating section 115 and a second radiating section 116. The grounding point 113 may be directly or indirectly electrically connected to the floor 150 to achieve grounding. The first end 111 and the second end 112 are two ends / free ends / terminals of the first radiator 110. The first radiator 110 may also include a feeding point 114. The signal source 140 may be directly or indirectly electrically connected to the feeding point 114. The signal source 140 may provide a first excitation signal to the first radiator 110 through the feeding point 114. The second radiator 120 is spaced apart from the first radiator 110, and the second radiator 120 may include a third end 121 and a fourth end 122, which may be two ends of the second radiator 120, the third end 121 is spaced apart from the first end 111 and forms a first coupling gap 101, the fourth end 122 may extend in a direction away from the first radiator 110 and be electrically connected to the floor 150 for grounding, and the first excitation signal provided by the signal source 140 may be electromagnetically coupled to the second radiator 120 through the first coupling gap 101, so that the second radiator 120 may be electromagnetically coupled to the first radiator 110. The third radiator 130 is spaced apart from the first radiator 110, and the third radiator 130 may include a fifth end 131 and a sixth end 132, which may be two ends of the third radiator 130, the fifth end 131 is spaced apart from the second end 112 and forms a second coupling gap 102, the sixth end 132 may extend in a direction away from the first radiator 110 and be electrically connected to the floor 150 for grounding, and the first excitation signal provided by the signal source 140 may also be electromagnetically coupled to the third radiator 130 through the second coupling gap 102, so that the third radiator 130 may be electromagnetically coupled to the first radiator 110.

[0031] Among them, the electrical length of the first radiation section 115 between the first end 111 of the first radiator 110 and the grounding point 113 and at least one radiation structure in the second radiator 120 is greater than (including slightly greater than) one quarter of the wavelength corresponding to the first wireless signal, and the electrical length of the second radiator 120 is not equal to one quarter of the wavelength corresponding to the first wireless signal, so that the signal source 140 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly realize the transmission and reception of the first wireless signal in a circularly polarized manner (transmission and reception include reception and transmission, which will not be repeated later). The electrical length of the second radiation section 116 between the second end 112 of the first radiator 110 and the grounding point 113 and at least one radiation structure in the third radiator 130 is greater than (including slightly greater than) one quarter of the wavelength corresponding to the second wireless signal, and the electrical length of the third radiator 130 is not equal to one quarter of the wavelength corresponding to the second wireless signal, so that the signal source 140 excites the second radiation section 116, the third radiator 130 and the floor 150 to jointly realize the transmission and reception of the second wireless signal in a circularly polarized manner.

[0032] It is understandable that the floor 150 may be a common ground of the electronic device 10, the floor 150 may be a plane or structure with zero electric potential, and the floor 150 may be formed by a conductor, a printed circuit, or a metal printed layer in the electronic device 10. For example, the floor 150 may be formed on a main board, a small board, or other supporting board of the electronic device 10; for another example, the floor 150 may also be formed on a frame (such as a middle frame or middle board described later) of the electronic device 10. The specific location of the floor 150 is not limited in the embodiment of the present application.

[0033] It can be understood that the feeding point 114 on the first radiator 110 can be arranged between the first end 111 and the second end 112 of the first radiator 110, for example, the feeding point 114 can be located in the area between the first end 111 and the grounding point 113, or the feeding point 114 can be located in the area between the second end 112 and the grounding point 113. Of course, the feeding point 114 can also be arranged at the first end 111 or the second end 112, in which case the first end 111 or the second end 112 can be the feeding end of the first radiator 110. The embodiment of the present application does not limit the specific setting position of the feeding point 114.

[0034] It can be understood that the first radiator 110, the second radiator 120, and the third radiator 130 can all be radiating devices with conductor structures. The second radiator 120 can be located on the side where the first end 111 of the first radiator 110 is located, so that the first radiator 110 can be arranged mouth-to-mouth with the second radiator 120, and the third radiator 130 can be located on the side where the second end 112 of the first radiator 110 is located, so that the first radiator 110 can be arranged mouth-to-mouth with the third radiator 130, so that the three radiators in the embodiment of the present application can realize two groups of mouth-to-mouth radiation structures.

[0035] It can be understood that the first radiator 110, the second radiator 120, and the third radiator 130 can be, but are not limited to, strip structures extending in the same direction, so that the first radiator 110, the second radiator 120, and the third radiator 130 can form two groups of mouth-to-mouth antenna radiation structures. Of course, at least one of the first radiator 110, the second radiator 120, and the third radiator 130 can also be in other shapes. For example, the first radiator 110 can be in a bent shape, in which case part of the first radiator 110 can also extend in the same direction as the second radiator 120, and another part of the first radiator 110 can extend in another direction with the third radiator 130. In addition, when the grounding point 113 is located at the corner of the bent shape, part of the first radiator 110 and the second radiator 120 can extend in the same direction to form a group of mouth-to-mouth antenna radiation structures, and another part of the first radiator 110 and the third radiator 130 can extend in another direction to form another group of mouth-to-mouth antenna radiation structures. The embodiment of the present application does not limit the specific structures of the first radiator 110 , the second radiator 120 and the third radiator 130 .

[0036] It can be understood that the signal source 140 can convert high-frequency excitation signals or bound electromagnetic waves into radiated electromagnetic energy. For example, the signal source 140 can provide a first excitation signal to the first radiator 110, and the first excitation signal can excite the first radiator 110, the second radiator 120, the third radiator 130 and the floor 150 to support the transmission of the first wireless signal and the second wireless signal; at the same time, the first radiator 110, the second radiator 120, and the third radiator 130 can also capture and bind electromagnetic waves in the free space and transmit them to the signal source 140 to form a current signal, so that the first radiator 110, the second radiator 120, the third radiator 130 and the floor 150 can jointly support the reception of the first wireless signal and the second wireless signal.

[0037] It can be understood that when the signal source 140 provides a first excitation signal, the first excitation signal can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly form a first resonance and generate a first resonant current, the first radiation section 115 and the second radiator 120 can be electromagnetically coupled, the first resonant current can flow on the first radiation section 115 and the second radiator 120, and the first resonant current can also flow to the floor 150 and flow on the floor 150, or an induced current with the same current intensity as the first resonant current can be generated on the floor 150, so that, under the excitation of the signal source 140, the first radiation section 115, the second radiator 120 and the floor 150 can jointly support the first wireless signal in a circularly polarized manner. Similarly, the first excitation signal can also excite the second radiation segment 116, the third radiator 130 and the floor 150 to jointly form a second resonance and generate a second resonant current. The second radiation segment 116 and the third radiator 130 can be electromagnetically coupled, and the second resonant current can flow on the second radiation segment 116 and the third radiator 130. Moreover, the second resonant current can also flow to the floor 150 and flow on the floor 150, or an induced current with the same current intensity as the second resonant current can be generated on the floor 150. Therefore, under the excitation of the signal source 140, the second radiation segment 116, the third radiator 130 and the floor 150 can jointly support the second wireless signal in a circularly polarized manner.

[0038] It can be understood that the signal source 140 can independently excite the first radiation section 115, the second radiator 120 and the floor 150 to produce a first resonance and jointly realize the reception and transmission of the first wireless signal in a circularly polarized manner; the signal source 140 can also independently excite the second radiation section 116, the third radiator 130 and the floor 150 to produce a second resonance and jointly realize the reception and transmission of the second wireless signal in a circularly polarized manner; the signal source 140 can also simultaneously excite the first radiation section 115, the second radiator 120, the floor 150, the second radiation section 116, the third radiator 130 to produce a first resonance and a second resonance and realize the reception and transmission of the first wireless signal and the second wireless signal in a circularly polarized manner.

[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 the plane perpendicular to the propagation direction is a circle; when the horizontal component and the vertical component of the electric field have equal amplitudes and a phase difference of 90 degrees or 270 degrees, circular polarization can be achieved; 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, the second radiator 120, the third radiator 130, and the floor 150 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 the communication performance between the first radiator 110, the second radiator 120, the third radiator 130 and the floor 150 and the communication satellite; it can also eliminate polarization distortion and improve the anti-interference performance of the antenna device 100 and the electronic device 10.

[0040] It can be understood that the electrical lengths of the first radiation segment 115 of the first radiator 110 and the second radiator 120 can be specially designed so that the electrical length of at least one radiation structure in the first radiation segment 115 and the second radiator 120 is greater than one quarter of the wavelength corresponding to the first wireless signal, and the electrical length of the second radiator 120 is not equal to one quarter of the wavelength corresponding to the first wireless signal. When the signal source 140 provides a first excitation signal, the signal source 140 can excite the first radiation segment 115, the second radiator 120 and the floor 150 to jointly form a ring-shaped or arc-shaped (non-linear) resonant current path, so that the first radiation segment 115, the second radiator 120 and the floor 150 can jointly support the transmission and reception of the first wireless signal in a circularly polarized manner. Of course, the electrical lengths of the second radiation segment 116 and the third radiator 130 of the first radiator 110 can also be specially designed so that the electrical length of at least one of the second radiation segment 116 and the third radiator 130 is greater than one quarter of the wavelength corresponding to the second wireless signal, and the electrical length of the third radiator 130 is not equal to one quarter of the wavelength corresponding to the second wireless signal. When the signal source 140 provides a first excitation signal, the signal source 140 can excite the second radiation segment 116, the third radiator 130 and the floor 150 to jointly form a ring-shaped or arc-shaped (non-linear) resonant current path, so that the second radiation segment 116, the third radiator 130 and the floor 150 can jointly support the transmission and reception of the second wireless signal in a circularly polarized manner.

[0041] It can be understood that the electrical length of the radiation structure refers to the equivalent length when the radiation structure radiates a wireless signal, or the equivalent length required for electromagnetic wave transmission in the radiation structure. The electrical length of the radiation structure can be greater than, less than or equal to the physical length of its branches. The electrical length of the radiator can be changed by changing the grounding point 113 of the radiator, the structure and parameters of the electrically connected adjustment circuit, tuning circuit, and matching circuit. Among them, the electrical length of the radiator can be associated with the frequency 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.

[0042] It can be understood that when the electrical length of at least one of the first radiation section 115 and the second radiator 120 is greater than one quarter of the wavelength corresponding to the first wireless signal, and the electrical length of the second radiator 120 is not equal to one quarter of the wavelength corresponding to the first wireless signal, when the first resonant current generated by the excitation of the signal source 140 flows on the first radiation section 115 and the second radiator 120, the resonant current flow direction on a part of the radiation structure will be opposite to the resonant current flow direction on another part of the radiation structure, so that an arc-shaped (non-linear) resonant current path can be generated on the floor 150. Thus, the signal source 140 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a circularly polarized manner.

[0043] For example, please refer to Figure 2 and Figure 3 , Figure 2 for Figure 1 The first resonant current distribution diagram of the electronic device 10 is shown in FIG. Figure 3 for Figure 1 The first circular polarization radiation pattern of the electronic device 10 is shown. Figure 2 As shown, the flow direction of the first resonant current I1 generated by the signal source 140 on at least a portion of the second radiator 120 is opposite to that on a portion of the first radiating section 115. For example, Figure 2 The first resonant current I1 can flow upward clockwise from the first end 111 to the grounding point 113 on the first radiation segment 115 and can return to the ground through the grounding point 113. The flow direction of the first resonant current I1 in the area near the first radiation segment 115 on the second radiator 120 (for example, from the third end 121 to a certain area point of the second radiator 120, so that the electrical length from the area point to the third end 121 is approximately one-fourth of the wavelength corresponding to the first wireless signal) is opposite to the flow direction on the first radiator 110, for example, it can flow downward. At the same time, the flow direction of the first resonant current I1 in the area from the area point of the second radiator 120 to the fourth end 122 is the same as the flow direction on the first radiator 110, for example, it can flow upward clockwise. Furthermore, the floor 150, under the excitation of the first resonant current I1 in the area near the first radiator 110 and the second radiator 120, can generate a resonant current path opposite to the current flow on the first radiator 110 and the second radiator 120, so that the first resonant current I1 can excite the floor 150 to generate an arc-shaped (non-linear) resonant current path, and the horizontal component and vertical component of the electric field generated by the arc-shaped resonant current path are equal in amplitude and have a phase difference of ninety degrees or two hundred and seventy degrees. Therefore, under the influence of the arc-shaped resonant current path, the first resonant current I1 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a circularly polarized manner relative to the reference plane M0. Figure 3As shown, taking the positions of the first radiation segment 115, the second radiator 120 and the floor 150 as base points (generally taking the surface where the floor 150 is located as the base point), the first radiation segment 115, the second radiator 120 and the floor 150 can form a circular polarization pattern (for example, a right-handed circular polarization pattern) when they jointly support the first wireless signal relative to the reference plane M0.

[0044] It should be noted that, since the signal source 140 feeds an excitation signal from the feeding point 114 to the first radiator 110, when the feeding point 114 is set in the area between the second end 112 and the grounding point 113, the first resonant current I1 generated by the signal source 140 can also flow from the first radiation section 115 to the feeding point 114 when flowing on the first radiator 110. At this time, the radiation section between the feeding point 114 and the grounding point 113 can also support the transmission and reception of the first wireless signal in a circularly polarized manner together with the first radiation section 115, the second radiator 120 and the floor 150. This embodiment of the present application is not limited to this.

[0045] For further example, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The second resonant current distribution diagram of the electronic device 10 is shown in FIG. Figure 5 for Figure 1 The second circular polarization radiation pattern of the electronic device 10 is shown. Figure 4 As shown, the flow direction of the second resonant current I2 generated by the signal source 140 on at least part of the third radiator 130 is opposite to that on at least the second radiating section 116, for example. Figure 2 The second resonant current I2 may flow from the second end 112 to the grounding point 113 on the second radiation section 116 of the first radiator 110 and return to the ground from the grounding point 113 of the first radiator 110. At the same time, the second resonant current I2 may be electromagnetically coupled to the third radiator 130 and may flow along the fifth end 131 to the sixth end 132 on the third radiator 130, and flow to the circuit board 400 through the grounding path of the third radiator 130; and, under the excitation of the second resonant current I2 in the area near the first radiator 110 and the second radiator 120, the floor 150 A resonant current path opposite to the current flow on the first radiator 110 and the second radiator 120 can be generated, so that the second resonant current I2 can excite the floor 150 to generate an arc-shaped (non-linear) resonant current path. The horizontal component and the vertical component of the electric field generated by the arc-shaped resonant current path have equal amplitudes and a phase difference of 90 degrees or 270 degrees. Therefore, under the influence of the arc-shaped resonant current path, the second resonant current I2 can excite the second radiation section 116, the third radiator 130 and the floor 150 to jointly support the second wireless signal in a circularly polarized manner relative to the reference plane M0. Figure 5 As shown, taking the positions of the second radiation segment 116, the third radiator 130 and the floor 150 as base points (generally taking the surface where the floor 150 is located as the base point), the second radiation segment 116, the third radiator 130 and the floor 150 can form a circular polarization pattern (for example, a left-handed circular polarization pattern) when they jointly support the second wireless signal relative to the reference plane M0.

[0046] It is understandable that if Figure 3 As shown, the first wireless signal can be, but is not limited to, a wireless signal in the 2 GHz frequency band, the overall circular polarization gain (Gain-Abs) parameter of the first wireless signal can be 2.078 dBi, and the right-hand circular polarization gain (Gain-Right) parameter of the first wireless signal can be 1.975 dBi. Thus, with the surface where the floor 150 is located as the base point relative to the reference plane M0, the first radiation section 115, the second radiator 120 and the floor 150 can jointly support the first wireless signal in a right-hand circular polarization manner. Similarly, Figure 5 As shown, the second wireless signal can be, but is not limited to, a wireless signal in the 3.38 GHz frequency band, the overall circular polarization gain (Gain-Abs) parameter of the second wireless signal can be 2.911 dBi, and the left-hand circular polarization gain (Gain-Left) parameter of the second wireless signal can be 1.646 dBi, so that, with the surface where the floor 150 is located as the base point relative to the reference plane M0, the second radiation segment 116, the third radiator 130 and the floor 150 jointly support the second wireless signal in a left-hand circular polarization manner. Of course, the first wireless signal and the second wireless signal can also be wireless signals in other frequency bands, and the first wireless signal and the second wireless signal can also be other circular polarization modes, which is not limited in the embodiments of the present application.

[0047] It can be understood that, with the plane where the floor 150 is located as the base point relative to the reference plane M0, when the first radiation segment 115, the second radiator 120 and the floor 150 jointly support the first wireless signal in a right-hand circular polarization mode, and the second radiation segment 116, the third radiator 130 and the floor 150 jointly support the second wireless signal in a left-hand circular polarization mode, by comparison Figure 3 and Figure 5 The circular polarization pattern shown in FIG. 1 can determine that the angle of maximum beam overlap between the two can be 45° above the reference plane M0 or the plane opposite to the reference plane M0. Figure 6 As shown, Figure 6 Schematic diagram of the maximum radiation direction when the electronic device 10 supports the first wireless signal and the second wireless signal at the same time, from Figure 6 It can be seen that when the electronic device 10 supports the first wireless signal and the second wireless signal at the same time, the maximum radiation direction is 45° above the reference plane M0 or the surface opposite to the reference plane M0, which can be suitable for satellite communication scenarios.

[0048] 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 of the main beam of the antenna. Figure 3 As shown in the embodiment of the present application, when the first radiation section 115, the second radiator 120 and the floor 150 jointly support the first wireless signal, with the surface where the floor 150 is located as the base point relative to the reference plane M0, the maximum radiation beam of the first radiation section 115, the second radiator 120 and the floor 150 is oriented in a direction above the reference plane M0; Figure 5 As shown, the radiation capability of the second radiation section 116, the third radiator 130 and the floor 150 when jointly supporting the second wireless signal is concentrated in the direction toward the reference plane M0. The polarization mode and polarization direction of the antenna affect the form of propagation of the main beam of the antenna in space. Generally, when the main beam is linearly polarized, the linearly polarized electromagnetic wave can be received by another antenna supporting linear polarization; when the main beam is circularly polarized, the circularly polarized electromagnetic wave can be received by another antenna supporting 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. Further, the polarization direction is the direction of the polarization form of the antenna. The linear polarization can have polarization directions such as ±45° linear polarization direction, horizontal polarization direction, and vertical polarization direction; the circular polarization can have left-handed circular polarization direction and right-handed 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 10 of the present application preferably also receives the signal in a left-hand circular polarization direction. If the electronic device 10 of the present application receives the signal in a right-hand circular polarization direction, it basically cannot receive the signal transmitted by the satellite antenna.

[0049] 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 10 of the present application can transmit and receive signals in a circularly polarized manner, and the electronic device 10 of the present application can communicate better with the satellite antenna; in addition, the main beam direction when the first radiation section 115, the second radiator 120 and the floor 150 of the embodiment of the present application jointly support the first wireless signal, and the second radiation section 116, the third radiator 130 and the floor 150 jointly support the second wireless signal is a fixed direction perpendicular to the floor 150, and the radiation beam of the electronic device 10 of the present application has the characteristics of directional high gain, so the electronic device 10 of the present application is very suitable for satellite communication.

[0050] In the electronic device 10 of the embodiment of the present application, the first radiation section 115 of the first radiator 110 can form a group of "mouth-to-mouth" radiation structures with the second radiator 120, and the second radiator 120 can be electromagnetically coupled to the first radiator 110; the second radiation section 116 of the first radiator 110 can form another group of "mouth-to-mouth" radiation structures with the third radiator 130, and the third radiator 130 can also be electromagnetically coupled to the first radiator 110; by specially designing the electrical lengths of the first radiation section 115, the second radiation section 116, the second radiator 120 and the third radiator 130 of the first radiator 110, at least one of the first radiation section 115 of the first radiator 110 and the second radiator 120 The electrical length is greater than one-quarter of the wavelength corresponding to the first wireless signal, and the electrical length of the second radiator 120 is not equal to one-quarter of the wavelength corresponding to the first wireless signal, and the signal source 140 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a circularly polarized manner; at the same time, the electrical length of at least one of the second radiation section 116 of the first radiator 110 and the third radiator 130 is greater than one-quarter of the wavelength corresponding to the second wireless signal, and the electrical length of the third radiator 130 is not equal to one-quarter of the wavelength corresponding to the first wireless signal, and the signal source 140 can excite the second radiation section 116, the third radiator 130 and the floor 150 to jointly support the second wireless signal in a circularly polarized manner. Thus, the antenna device 100 of the electronic device 10 of the embodiment of the present application can realize dual-frequency circularly polarized radiation, the antenna device 100 has better circular polarization performance, the radiation performance of the antenna device 100 with satellite communication is better, and the electronic device 10 can be more suitable for the use scenario of satellite communication.

[0051] Please refer again to Figures 1 to 5 The electrical lengths of the first radiation section 115, the second radiation section 116, the second radiator 120, and the third radiator 130 may be designed so that the frequency of the first wireless signal is the same as or different from the frequency of the second wireless signal.

[0052] Exemplarily, the sum of the electrical length of the first radiation segment 115 and the electrical length of the second radiator 120 may be equal to the sum of the electrical lengths of the second radiation segment 116 and the third radiator 130, so that the frequency of the first wireless signal is the same as the frequency of the second wireless signal. The same frequencies of the two wireless signals may mean that the frequency ranges of the two wireless signals are completely included in the frequency range of one wireless signal in the frequency spectrum, or that the center frequencies of the two wireless signals are the same.

[0053] As another example, the electrical length of the first radiation segment 115 may be different from the electrical length of the second radiation segment 116, and the electrical length of the second radiator 120 may be different from the electrical length of the third radiator 130. In this case, the total electrical length of the first radiation segment 115 and the second radiator 120 may be different from the total electrical length of the second radiation segment 116 and the third radiator 130, and the frequency of the first wireless signal supported by the antenna device 100 may be different from the frequency of the second wireless signal. The different frequencies of the two wireless signals may refer to that the frequency ranges of the two wireless signals are completely spaced apart on the spectrum, or may refer to that the frequency ranges of the two wireless signals partially intersect and the center frequencies of the two are different. For example, the center frequency of the first wireless signal may be, but not limited to, 2 GHz, and the center frequency of the second wireless signal may be, but not limited to, 3.3 GHz. This is not limited in the embodiments of the present application.

[0054] It should be noted that, in theory, the sum of the first electrical lengths of the first radiation section 115 and the second radiator 120 is equal to the sum of the second electrical lengths of the second radiation section 116 and the third radiator 130, then the frequencies of the first wireless signal and the second wireless signal can be the same; if the sum of the first electrical lengths of the first radiation section 115 and the second radiator 120 is not equal to the sum of the second electrical lengths of the second radiation section 116 and the third radiator 130, then the frequencies of the first wireless signal and the second wireless signal are different. In actual debugging, considering that the first radiation section 115 and the second radiation section 116 share the same grounding point 113 and feeding point 114, therefore, in actual debugging, if the first electrical length is approximately equal to the second electrical length, the frequencies of the two wireless signals can be the same, and if the first electrical length and the second electrical length are significantly different, the frequencies of the two wireless signals can be different. Moreover, when the first wireless signal and the second wireless signal need to be signals of different frequencies, the electrical lengths of the first radiating section 115 and the second radiating section 116 are often made different in actual debugging, so that the first radiating section 115 can better support the transmission and reception of the first wireless signal together with the second radiator 120 and the floor 150, and the second radiating section 116 can better support the transmission and reception of the second wireless signal together with the third radiator 130 and the floor 150.

[0055] Among them, when the electrical lengths of the first radiating section 115 of the first radiator 110 and the second radiator 120 are designed to have different electrical length values, the first radiating section 115, the second radiator 120 and the floor 150 can support the transmission and reception of the first wireless signal in circular polarization modes with different rotation directions.

[0056] Exemplarily, when the electrical length of the second radiator 120 is greater than one-quarter of the wavelength corresponding to the first wireless signal, the electrical length of the first radiation section 115 may be greater than, less than or equal to one-quarter of the wavelength corresponding to the first wireless signal, and the current phase of the first resonant current I1 generated by the excitation of the signal source 140 on the first radiation section 115 is ahead of its current phase on the second radiator 120, and the current phase of the first resonant current I1 on the second radiator 120 lags behind its current phase on the first radiation section 115. The first resonant current I1 may flow in the direction from the first radiation section 115 to the second radiator 120 and may form a clockwise arc-shaped current path on the floor 150. The signal source 140 may excite the first radiator 110, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a first circular polarization, such as right-hand circular polarization, relative to the reference plane M0. Figure 3 As shown, for example, the back shell surface of the electronic device is selected as the reference plane M0. At this time, taking the plane where the floor 150 is located as the base point, the maximum radiation beam generated by the first radiation section 115, the second radiator 120 and the floor 150 toward the reference plane M0 / back shell surface is a right-handed circularly polarized beam, and the maximum radiation beam toward the display surface / away from the reference plane M0 is a left-handed circularly polarized beam. A right-handed circularly polarized beam (for example, a right-handed circularly polarized beam) of the electronic device 10 can be directed toward the reference plane M0.

[0057] As another example, when the electrical length of the second radiator 120 is less than one-fourth of the wavelength corresponding to the first wireless signal, at this time, the electrical length of the first radiation segment 115 of the first radiator 110 is greater than one-fourth of the wavelength corresponding to the first wireless signal. The current phase of the first resonant current I1 generated by the excitation of the signal source 140 on the second radiator 120 is ahead of its current phase on the first radiation segment 115, and the current phase of the first resonant current I1 on the first radiation segment 115 lags behind its current phase on the second radiator 120. The flow direction of the first resonant current I1 on at least part of the first radiation segment 115 is opposite to its flow direction on part of the second radiator 120. The first resonant current I1 flows from the second radiator 120 to the first radiation segment 115. The first resonant current I1 can excite the generation of an arc-shaped (non-linear) current path in a counterclockwise pattern on the floor 150. The horizontal component and the vertical component of the electric field generated by the arc-shaped current path have equal amplitudes and phases. The difference is ninety degrees or two hundred and seventy degrees, so that under the influence of the counterclockwise arc current path, the first resonant current I1 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a second circular polarization, such as left-hand circular polarization, relative to the reference plane M0. The left-hand circularly polarized beam of the electronic device 10 can be directed toward the reference plane M0. For example, the rear shell surface of the electronic device 10 is selected as the reference plane M0. At this time, the surface where the floor 150 is located is taken as the base point. The maximum radiation beam generated by the first radiation section 115, the second radiator 120 and the floor 150 toward the reference plane M0 / back shell surface is a left-hand circularly polarized beam, and the maximum radiation beam toward the display surface / away from the reference plane M0 is a right-hand circularly polarized beam.

[0058] It can be understood that left-hand circular polarization and right-hand circular polarization are in a relative relationship. When the selected reference plane M0 is different, the same circularly polarized radiation beam can be circularly polarized with different rotation directions under different reference planes M0. For example, if a circularly polarized beam facing a certain reference plane M0 is defined as a left-hand circularly polarized beam, then the circularly polarized beam facing away from the reference plane M0 is a right-hand circularly polarized beam. Conversely, if the other side opposite to the reference plane M0 is used as a new reference plane, the circularly polarized beam facing the new reference plane is a right-hand circularly polarized beam, and the circularly polarized beam facing away from the new reference plane is a left-hand circularly polarized beam. The first circular polarization and the second circular polarization of the embodiments of the present application are not specifically limited to left-hand and right-hand.

[0059] Among them, when the electrical lengths of the second radiating segment 116 of the first radiator 110 and the third radiator 130 are designed with different electrical length values, the second radiating segment 116, the third radiator 130 and the floor 150 can also support the transmission and reception of the second wireless signal in circular polarization modes with different rotation directions.

[0060] Exemplarily, when the electrical length of the third radiator 130 is greater than one-quarter of the wavelength corresponding to the second wireless signal, the electrical length of the second radiation segment 116 may be greater than, less than or equal to one-quarter of the wavelength corresponding to the second wireless signal, and the current phase of the second resonant current I2 generated by the excitation of the signal source 140 on the second radiation segment 116 is ahead of its current phase on the third radiator 130, and the current phase of the second resonant current I2 on the third radiator 130 is ahead of its current phase on the second radiation segment 116, and the second resonant current I2 may flow in the direction from the second radiation segment 116 to the third radiator 130 and may form an arc-shaped current in a clockwise mode on the floor 150. Path, the signal source 140 can excite the second radiation segment 116, the second radiator 120 and the floor 150 to jointly support the second wireless signal in a third circular polarization manner, such as right-hand circular polarization, relative to the reference plane M0. A right-hand circularly polarized beam (such as a right-hand circularly polarized beam) of the electronic device 10 can be directed toward the reference plane M0. For example, the back shell surface of the electronic device 10 is selected as the reference plane M0. At this time, the surface where the floor 150 is located is taken as the base point. The maximum radiation beam generated by the second radiation segment 116, the second radiator 120 and the floor 150 toward the reference plane M0 / back shell surface is a right-hand circularly polarized beam, and the maximum radiation beam toward the display surface / away from the reference plane M0 is a left-hand circularly polarized beam.

[0061] As another example, when the electrical length of the third radiator 130 is less than one-fourth of the wavelength corresponding to the second wireless signal, at this time, the electrical length of the second radiation segment 116 of the first radiator 110 is greater than one-fourth of the wavelength corresponding to the second wireless signal. The current phase of the second resonant current I2 generated by the excitation of the signal source 140 on the third radiator 130 is ahead of its current phase on the second radiation segment 116, the current phase of the second resonant current I2 on the second radiation segment 116 lags behind its current phase on the third radiator 130, the flow direction of the second resonant current I2 on at least part of the second radiation segment 116 is opposite to its flow direction on part of the third radiator 130, and the second resonant current I2 can flow in the direction from the third radiator 130 to the second radiation segment 116, as shown in FIG. Figure 4As shown, the second resonant current I2 can excite the floor 150 to generate an arc-shaped (non-linear) current path in a counterclockwise mode. The horizontal component and the vertical component of the electric field generated by the arc-shaped current path have equal amplitudes and a phase difference of ninety degrees or two hundred and seventy degrees. Therefore, under the influence of the counterclockwise arc-shaped current path, the second resonant current I2 can excite the second radiation segment 116, the third radiator 130 and the floor 150 to jointly support the second wireless signal in a fourth circular polarization, such as left-hand circular polarization, relative to the reference plane M0. The left-hand circularly polarized beam of the electronic device 10 can be directed toward the reference plane M0. For example, the rear shell surface of the electronic device 10 is selected as the reference plane M0. At this time, with the surface where the floor 150 is located as the base point, the maximum radiation beam generated by the second radiation segment 116, the third radiator 130 and the floor 150 toward the reference plane M0 / rear shell surface is a left-hand circularly polarized beam, and the maximum radiation beam toward the display surface / away from the reference plane M0 is a right-hand circularly polarized beam.

[0062] It can be understood that the electrical length of the radiator or the radiating section in the above embodiment is greater than or less than one-quarter of the wavelength corresponding to the wireless signal, including that the electrical length of the radiator or the radiating section is slightly greater than or slightly less than one-quarter of the wavelength corresponding to the wireless signal. Among them, the electrical length of the second radiator 120 is slightly greater than one-quarter of the wavelength corresponding to the first wireless signal. At this time, the difference between the electrical length of the second radiator 120 and one-quarter of the wavelength corresponding to the first wireless signal can be greater than or equal to one-sixteenth of the wavelength corresponding to the first wireless signal. Similarly, the electrical length of the third radiator 130 is slightly greater than one-quarter of the wavelength corresponding to the second wireless signal, which can be that the difference between the electrical length of the third radiator 130 and one-quarter of the wavelength corresponding to the second wireless signal is greater than or equal to one-sixteenth of the wavelength corresponding to the second wireless signal. For another example, the electrical length of the second radiator 120 is slightly less than one-quarter of the wavelength corresponding to the first wireless signal, which can mean that the difference between one-quarter of the wavelength corresponding to the first wireless signal and the electrical length of the second radiator 120 can be greater than or equal to one-sixteenth of the wavelength corresponding to the first wireless signal. Similarly, the electrical length of the third radiator 130 is slightly smaller than one quarter of the wavelength corresponding to the second wireless signal, which may mean that the difference between one quarter of the wavelength corresponding to the second wireless signal and the electrical length of the third radiator 130 is greater than or equal to one sixteenth of the wavelength corresponding to the second wireless signal.

[0063] It can be understood that the electrical length of the first radiation section 115 of the first radiator 110 of the embodiment of the present application can be equal to or slightly greater than one-quarter of the wavelength corresponding to the first wireless signal, and the electrical length of the second radiation section 116 can be slightly greater than one-quarter of the wavelength corresponding to the second wireless signal. At this time, only the lengths of the second radiator 120 and the third radiator 130 can be changed to realize different circularly polarized radiation modes of the electronic device 10. For example, the electrical length of the second radiator 120 can be made greater than one-quarter of the wavelength corresponding to the first wireless signal, so that the signal source 140 excites the first radiation section 115 of the first radiator 110, the second radiator 120 and the floor 150 relative to the reference plane M0 to jointly support the first wireless signal in a first circular polarization (for example, right-hand circular polarization) manner; the electrical length of the third radiator 130 can be made less than one-quarter of the wavelength corresponding to the second wireless signal, so that the signal source 140 excites the second radiation section 116 of the first radiator 110, the third radiator 130 and the floor 150 to jointly support the second wireless signal in a fourth circular polarization (for example, left-hand circular polarization) manner. At this time, the electronic device 10 can realize a dual-frequency and dual-rotation circularly polarized radiation mode. The electronic device 10 can more easily set circularly polarized radiation modes with different rotation directions, which can simplify the debugging difficulty of the electronic device 10.

[0064] It should be noted that the first radiation segment 115, the second radiation segment 116, the second radiator 120, and the third radiator 130 may also have other electrical lengths so that the electronic device 10 can support the first wireless signal and the second wireless signal in circular polarization modes with other rotation directions. The embodiments of the present application are not limited to this.

[0065] The antenna device 100 of the embodiment of the present application can form a circularly polarized radiation mode of any rotation direction when supporting the first wireless signal and the second wireless signal by adjusting the electrical lengths of the first radiation segment 115, the second radiation segment 116, the second radiator 120, and the third radiator 130 of the first radiator 110. Compared with other solutions that set up complex radiation structures and circuit structures to achieve different circularly polarized radiation modes, the antenna device 100 of the embodiment of the present application has a simpler structure and is easier to be integrated into electronic devices 10 such as smart phones.

[0066] Among them, please refer to Figure 7 , Figure 7 The second structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may further include a first regulating circuit 160 .

[0067] The first adjustment circuit 160 can be directly or indirectly electrically connected to the second radiator 120. The first adjustment circuit 160 can adjust the electrical length of the second radiator 120 so that the signal source 140 excites the first radiation segment 115 of the first radiator 110, the second radiator 120 and the floor 150 to support the first wireless signal in a first circular polarization or a second circular polarization relative to the reference plane M0.

[0068] It can be understood that one end of the first adjustment circuit 160 can be electrically connected to the fourth end 122 of the second radiator 120, and the other end can be electrically connected to the floor 150 to achieve grounding. Alternatively, one end of the first adjustment circuit 160 can be electrically connected to the area between the third end 121 and the fourth end 122 of the second radiator 120 and close to the fourth end 122, and the other end of the first adjustment circuit 160 is grounded, so that the grounding position of the first adjustment circuit 160 is as far away from the first radiator 110 as possible, which is more conducive to the stimulation of the arc-shaped current path on the floor 150, and it is easier to stimulate the formation of a circularly polarized first wireless signal, and the radiation performance of the first wireless signal is better. Of course, the first adjustment circuit 160 can also be electrically connected to other positions of the second radiator 120. At this time, the radiation performance of the first wireless signal can be compensated by the first adjustment circuit 160, the matching circuit, etc. The embodiment of the present application does not limit the specific electrical connection method of the first adjustment circuit 160.

[0069] It can be understood that the first adjustment circuit 160 can adjust the electrical length of the second radiator 120 and make the electrical length of the second radiator 120 greater than one quarter of the wavelength corresponding to the first wireless signal, so that the signal source 140 can excite the first radiation section 115, the second radiator 120 and the floor 150 to support the first wireless signal in a first circular polarization manner relative to the reference plane M0. At this time, the electrical length of the first radiator 110 can be greater than, equal to or less than one quarter of the wavelength corresponding to the first wireless signal. When the electrical length of the first radiation section 115 is greater than one quarter of the wavelength corresponding to the first wireless signal, the first adjustment circuit 160 can adjust the electrical length of the second radiator 120 and make the electrical length of the second radiator 120 less than one quarter of the wavelength corresponding to the first wireless signal, and the signal source 140 can excite the first radiation section 115, the second radiator 120 and the floor 150 to support the first wireless signal in a second circular polarization manner relative to the reference plane M0. Among them, relative to the reference plane M0, one of the first circular polarization and the second circular polarization is left-hand circular polarization and the other is right-hand circular polarization.

[0070] It is understandable that the first adjustment circuit 160 may include, but is not limited to, one or more components of a capacitor, an inductor, or a switch, connected in series or in parallel to form a structure. Any structure that can change the electrical length of the second radiator 120 may be the first adjustment circuit 160 of the embodiment of the present application, and the embodiment of the present application does not limit this.

[0071] The electronic device 10 of the embodiment of the present application is provided with a first adjustment circuit 160, and the first adjustment circuit 160 can change the size of the electrical length of the second radiator 120, so that through the control of the first adjustment circuit 160, the electronic device 10 and the antenna device 100 can select a suitable left-handed or right-handed circularly polarized radiation mode to match the left-handed or right-handed circularly polarized radiation mode of the satellite antenna. The antenna device 100 of the embodiment of the present application can be a satellite antenna with a controllable circular polarization beam, and the electronic device 10 can be a communication device with a controllable circular polarization beam.

[0072] Among them, please refer to Figure 8 , Figure 8 A third structural schematic diagram of the electronic device 10 provided in an embodiment of the present application. The electronic device 10 may further include a second regulating circuit 170. The second regulating circuit 170 may be directly or indirectly electrically connected to the third radiator 130. The second regulating circuit 170 may adjust the electrical length of the third radiator 130 so that the signal source 140 excites the second radiation segment 116 of the first radiator 110, the third radiator 130 and the floor 150 to support the second wireless signal in a third circular polarization or a fourth circular polarization manner relative to the reference plane M0.

[0073] It can be understood that one end of the second adjustment circuit 170 can be electrically connected to the sixth end 132 of the third radiator 130, and the other end can be electrically connected to the floor 150 to achieve grounding. Alternatively, one end of the second adjustment circuit 170 can be electrically connected to the area between the fifth end 131 and the sixth end 132 of the third radiator 130 and close to the sixth end 132, and the other end of the second adjustment circuit 170 is grounded, so that the grounding position of the second adjustment circuit 170 is as far away from the first radiator 110 as possible, which is more conducive to the stimulation of the arc-shaped current path on the floor 150, and it is easier to stimulate the formation of a circularly polarized second wireless signal, and the radiation performance of the second wireless signal is better. Of course, the second adjustment circuit 170 can also be electrically connected to other positions of the third radiator 130. At this time, the radiation performance of the second wireless signal can be compensated by the second adjustment circuit 170, the matching circuit, etc. The embodiment of the present application does not limit the specific electrical connection method of the second adjustment circuit 170.

[0074] It can be understood that the second adjustment circuit 170 can adjust the electrical length of the third radiator 130 and make the electrical length of the third radiator 130 greater than one quarter of the wavelength corresponding to the second wireless signal, so that the signal source 140 can excite the second radiation section 116, the third radiator 130 and the floor 150 to support the second wireless signal in a third circular polarization manner relative to the reference plane M0. At this time, the electrical length of the third radiator 130 can be greater than, equal to or less than one quarter of the wavelength corresponding to the second wireless signal. When the electrical length of the second radiation section 116 is greater than one quarter of the wavelength corresponding to the second wireless signal, the second adjustment circuit 170 can adjust the electrical length of the third radiator 130 and make the electrical length of the third radiator 130 less than one quarter of the wavelength corresponding to the second wireless signal, and the signal source 140 can excite the second radiation section 116, the third radiator 130 and the floor 150 to support the second wireless signal in a fourth circular polarization manner relative to the reference plane M0. Among them, relative to the reference plane M0, one of the third circular polarization and the fourth circular polarization is left-hand circular polarization and the other is right-hand circular polarization.

[0075] It is understandable that the second adjustment circuit 170 may include, but is not limited to, one or more components of a capacitor, an inductor, or a switch, connected in series or in parallel to form a structure. Any structure that can change the electrical length of the third radiator 130 may be the second adjustment circuit 170 of the embodiment of the present application, and the embodiment of the present application does not limit this.

[0076] It is understandable that the electronic device 10 may include a first adjustment circuit 160 so that the electronic device 10 can adjust the circular polarization mode of the first wireless signal; the electronic device 10 may also include a second adjustment circuit 170 so that the electronic device 10 can adjust the circular polarization mode of the second wireless signal; the electronic device 10 may also include both the first adjustment circuit 160 and the second adjustment circuit 170 so that the electronic device 10 can adjust the circular polarization mode of the first wireless signal and the second wireless signal at the same time. This embodiment of the application is not limited to this.

[0077] The electronic device 10 of the embodiment of the present application is provided with at least one of the first adjustment circuit 160 and the second adjustment circuit 170. The first adjustment circuit 160 can change the size of the electrical length of the second radiator 120, and the second adjustment circuit 170 can change the size of the electrical length of the third radiator 130. Thus, through the control of the first adjustment circuit 160 and the second adjustment circuit 170, the electronic device 10 can select a suitable left-handed or right-handed circularly polarized radiation mode to support the first wireless signal or the second wireless signal. The electronic device 10 can select a suitable left-handed or right-handed circularly polarized radiation mode to match the left-handed or right-handed circularly polarized radiation mode of the satellite antenna. Thus, the electronic device 10 of the embodiment of the present application can be a communication device with controllable circularly polarized beam.

[0078] Among them, please refer to Fig. 9 , Fig. 9 for Figure 8 An electrical connection diagram of the electronic device 10 is shown. The first regulating circuit 160 may include one or more (two or more) inductive load branches 161 and one or more (two or more) capacitive load branches 162 .

[0079] One end of each inductive load branch 161 is used to be directly or indirectly electrically connected to the floor 150, and the other end of each inductive load branch 161 is used to be directly or indirectly electrically connected to the second radiator 120. One end of each capacitive load branch 162 is used to be directly or indirectly electrically connected to the floor 150, and the other end of each capacitive load branch 162 is used to be directly or indirectly electrically connected to the second radiator 120. The first regulating circuit 160 can turn on an inductive load branch 161 to be electrically connected to the second radiator 120 and the floor 150 respectively, so that the electrical length of the second radiator 120 is greater than one quarter of the wavelength corresponding to the first wireless signal. The current phase of the first resonant current I1 generated by the signal source 140 on the first radiation section 115 can be ahead of its current phase on the second radiator 120, and the current phase of the first resonant current I1 on the second radiator 120 lags behind its current phase on the first radiation section 115. The first resonant current I1 can excite the floor 150 to form an arc current path in a clockwise mode. The first resonant current I1 can excite the first radiation section 115, the second radiator 120 and the floor 150 to jointly support the first wireless signal in a first circular polarization, such as right-hand circular polarization, relative to the reference plane M0. The first adjustment circuit 160 can also conduct a capacitive load branch 162 to conduct with the second radiator 120 and the floor 150 respectively, so that the electrical length of the second radiator 120 is less than one-fourth of the wavelength corresponding to the first wireless signal, the current phase of the first resonant current I1 on the second radiator 120 can be ahead of the current phase on the first radiator 110, the first resonant current I1 can excite the formation of an arc current path in a counterclockwise mode on the floor 150, and the first resonant current I1 can excite the first radiation section 115, the second radiator 120 and the floor 150 to support the first wireless signal in a second circular polarization, such as left-hand circular polarization, relative to the reference plane M0. Therefore, the first adjustment circuit 160 can select the inductive load branch 161 or the capacitive load branch 162 to conduct to adjust the electrical length of the second radiator 120.

[0080] It can be understood that the inductive load branch 161 refers to a load with an inductance parameter. The inductive load branch 161 can make the load current lag behind the load circuit by a phase difference characteristic. The inductive load branch 161 may be, but is not limited to, a structure including one or more inductive elements connected in series and in parallel to the ground. Alternatively, the inductive load branch 161 may also be, but is not limited to, a structure with a zero ohm surface resistance (0 ohm) directly short-circuited to the ground (the second radiator 120 is directly grounded through a wire or a spring). Of course, the inductive load branch 161 may also be other inductive load structures, and the specific structure of the inductive load branch 161 is not limited in the embodiment of the present application.

[0081] It can be understood that the inductive load branch 161 can increase the electrical length of the second radiator 120, so that the second radiator 120 supports the transmission and reception of the first wireless signal of the corresponding frequency band. When the first adjustment circuit 160 includes multiple inductive load branches 161, the equivalent inductance values ​​of at least two inductive loads can be different, so that the first adjustment circuit 160 conducts different inductive load branches 161 to be electrically connected to the second radiator 120 and the floor 150 respectively, and the first adjustment circuit 160 can adjust the frequency range of the first wireless signal. For example, when the equivalent inductance value of the inductive load branch 161 is larger, the electrical length of the second radiator 120 is longer, and the frequency of the first wireless signal supported by the first radiator 110, the second radiator 120 and the floor 150 is lower; conversely, when the equivalent inductance value of the inductive load branch 161 is smaller, the electrical length of the second radiator 120 is shorter, and the frequency of the first wireless signal supported by the first radiator 110, the second radiator 120 and the floor 150 is higher.

[0082] It can be understood that the capacitive load branch 162 refers to a load with a capacitance parameter. The capacitive load branch 162 can make the load current exceed the structure of a phase difference characteristic of its load circuit. The capacitive load branch 162 may be, but is not limited to, a structure including one or more capacitive elements connected in series and in parallel to the ground. Of course, the capacitive load branch 162 may also be other capacitive load structures, and the embodiment of the present application does not limit the specific structure of the capacitive load branch 162. Among them, the capacitive load branch 162 can reduce the electrical length of the second radiator 120, so that the second radiator 120 supports the transmission and reception of the first wireless signal of the corresponding frequency band. When the first adjustment circuit 160 includes a plurality of capacitive load branches 162, the equivalent capacitance values ​​of at least two capacitive loads may be different, so that the first adjustment circuit 160 turns on different capacitive load branches 162 to be electrically connected to the second radiator 120 and the floor 150 respectively, and the first adjustment circuit 160 can adjust the frequency range of the first wireless signal.

[0083] The first regulating circuit 160 may further include a switch 163, which may include an input terminal, one or more (two or more) first output terminals, and one or more (two or more) second output terminals. The input terminal of the switch 163 may be electrically connected to the second radiator 120, each first output terminal of the switch 163 may be electrically connected to an inductive load branch 161, and each second output terminal may be electrically connected to a capacitive load. The switch 163 may control the input terminal to be connected to a first output terminal, or the switch 163 may control the input terminal to be connected to a second output terminal.

[0084] It is understandable that the first regulating circuit 160 can switch on the capacitive load branch 162 or the inductive load branch 161 by switching the switch 163 to adjust the first radiating section 115, the second radiator 120 and the floor 150 to support the first wireless signal in the first circular polarization or the second circular polarization. The first regulating circuit 160 can also switch on different capacitive load branches 162 by switching the switch 163 to adjust the frequency range of the first wireless signal, or the first regulating circuit 160 can also switch on different inductive load branches 161 by switching the switch 163 to adjust the frequency range of the first wireless signal.

[0085] It should be noted that the first regulating circuit 160 may not select different capacitive load branches 162 or inductive load branches 161 by switching the switch 163. For example, but not limited to, different capacitive load branches 162 and inductive load branches 161 may be provided with elements with adjustable parameters to achieve on or off connection, and the parameters of the elements may be adjusted to make different branches on or off. The specific structure of the first regulating circuit 160 is not limited in the embodiment of the present application.

[0086] The first adjustment circuit 160 of the embodiment of the present application includes a capacitive load branch 162 and an inductive load branch 161. By selecting different branches, the rotation direction of the circular polarization beam supported by the electronic device 10 for the first wireless signal can be adjusted. The first adjustment circuit 160 has a simple structure, and the method for the electronic device 10 to adjust the rotation direction of circular polarization is also simple.

[0087] It should be noted that the second regulating circuit 170 may also include one or more (two or more) inductive load branches and one or more (two or more) capacitive load branches. The structure of the second regulating circuit 170 may refer to the structure of the first regulating circuit 160 and is not limited here.

[0088] Among them, relative to the same reference plane M0, under the action of the first adjustment circuit 160 and the second adjustment circuit 170, the electronic device 10 can realize the transmission and reception of the first wireless signal and the second wireless signal in the same circular polarization mode. Of course, relative to the same reference plane M0, under the action of the first adjustment circuit 160 and the second adjustment circuit 170, the electronic device 10 can also realize the transmission and reception of the first wireless signal and the second wireless signal in different circular polarization modes. For example, relative to the same reference plane M0, the electronic device 10 can realize the transmission and reception of the first wireless signal and the second wireless signal in a left-hand circular polarization mode; or, relative to the same reference plane M0, the electronic device 10 can realize the transmission and reception of the first wireless signal and the second wireless signal in a right-hand circular polarization mode; or, relative to the same reference plane M0, the electronic device 10 can realize the transmission and reception of the first wireless signal in a left-hand circular polarization mode, and realize the transmission and reception of the second wireless signal in a right-hand circular polarization mode; or, the electronic device 10 can realize the transmission and reception of the first wireless signal in a right-hand circular polarization mode, and realize the transmission and reception of the second wireless signal in a left-hand circular polarization mode. Therefore, the electronic device 10 of the embodiment of the present application can realize dual-frequency dual co-circular polarization radiation, and can also realize dual-frequency dual hetero-circular polarization radiation, and the application scenarios of the electronic device 10 are wider.

[0089] It can be understood that, relative to the reference plane M0, under the action of the first adjustment circuit 160, the electronic device 10 can also transmit the first wireless signal in a first circular polarization mode and receive the first wireless signal in a second circular polarization mode, wherein one of the first circular polarization and the second circular polarization is left-hand circular polarization and the other is right-hand circular polarization. For example, relative to the reference plane M0, the electronic device 10 can transmit the first wireless signal in a left-hand circular polarization mode and receive the first wireless signal in a right-hand circular polarization mode; or, the electronic device 10 can transmit the first wireless signal in a right-hand circular polarization mode and receive the first wireless signal in a left-hand circular polarization mode. Thus, the electronic device 10 can receive and transmit the same first wireless signal in circular polarization modes of different rotation directions.

[0090] Similarly, relative to the reference plane M0, under the action of the second adjustment circuit 170, the electronic device 10 can transmit the second wireless signal in a third circular polarization mode and receive the second wireless signal in a fourth circular polarization mode, and one of the third circular polarization and the fourth circular polarization is left-hand circular polarization and the other is right-hand circular polarization. For example, relative to the reference plane M0, the electronic device 10 can transmit the second wireless signal in a left-hand circular polarization mode and receive the second wireless signal in a right-hand circular polarization mode; or, the electronic device 10 can transmit the second wireless signal in a right-hand circular polarization mode and receive the second wireless signal in a left-hand circular polarization mode, so that the electronic device 10 can receive and transmit the same second wireless signal in circular polarization modes of different rotation directions.

[0091] It is understandable that the first wireless signal and the second wireless signal in the embodiment of the present application can both be satellite signals. Of course, one of the first wireless signal and the second wireless signal can also be an L1 frequency band signal of a global positioning system (Global Positioning System, referred to as GPS) signal, and the other wireless signal can be an L5 frequency band signal of a GPS signal, so that the embodiment of the present application can realize the transmission and reception of GPS dual-band signals. Of course, the first wireless signal and the second wireless signal in the embodiment of the present application can also be other satellite signals or other circularly polarized signals, which are not limited in the embodiment of the present application.

[0092] The electronic device 10 of the embodiment of the present application can transmit and receive a first wireless signal in a circular polarization manner with different rotation directions, and the electronic device 10 can also transmit and receive a second wireless signal in a circular polarization manner with different rotation directions. Since current satellite communications often transmit and receive satellite signals in a circular polarization manner with different rotation directions, the present application can achieve that the electronic device 10 that transmits and receives signals in different rotation directions can better match the satellite, and can further improve the satellite communication performance of the electronic device 10.

[0093] Among them, please refer to Fig.10 , Fig.10 This is a fourth structural diagram of the electronic device 10 provided in an embodiment of the present application. The signal source 140 may also provide a second excitation signal, and the second excitation signal may at least excite the first radiator 110 to support a third wireless signal.

[0094] It can be understood that the third wireless signal may be different from the first wireless signal and also different from the third wireless signal. For example, the third wireless signal may be a wireless signal radiated in a linearly polarized manner. The signal source 140 may excite the first radiator 110 to support the linearly polarized third wireless signal. The first radiator 110 may realize a point-to-point communication connection between the base station and other antennas in a linearly polarized manner.

[0095] It can be understood that the third wireless signal can be but is not limited to wireless fidelity (Wireless Fidelity, referred to as Wi-Fi) signal, third generation mobile communication technology (3rd-Generation, referred to as 3G), fourth generation mobile communication technology (4th-Generation, referred to as 4G), fifth generation mobile communication technology (5th-Generation, referred to as 5G), near field communication (Near field communication, referred to as NFC) signal, Bluetooth (Blue tooth, referred to as BT) signal, etc. The embodiment of the present application does not limit the second wireless signal.

[0096] It can be understood that the second excitation signal provided by the signal source 140 can excite the first radiation section 115 of the first radiator 110 to support the third wireless signal, or can excite the second radiation section 116 of the first radiator 110 to support the third wireless signal, or can excite the first radiation section 115 and the second radiation section 116 of the first radiator 110 to jointly support the third wireless signal, or can excite at least part of the first radiator 110 and the second radiator 120 to jointly support the third wireless signal, or can excite at least part of the first radiator 110 and the third radiator 130 to jointly support the third wireless signal. This embodiment of the present application is not limited to this.

[0097] It can be understood that the signal source 140 can provide only the first excitation signal, so that the first radiator 110, the second radiator 120 and the floor 150 can jointly support the first wireless signal or the second wireless signal in a circularly polarized manner; the signal source 140 can also provide only the second excitation signal, so that the first radiator 110 supports the transmission of the third wireless signal in a linearly polarized manner; the signal source 140 can also provide the first excitation signal and the second excitation signal at the same time (for example, the signal source 140 includes two sub-signal sources, or the signal source 140 includes two feeding ports). In this case, the electric The sub-device 10 may, but is not limited to, further include a combiner 180, which can combine the first excitation signal and the second excitation signal transmitted by the two sub-signal sources of the signal source 140 or different ports into one path and transmit it to the first radiator 110, and at the same time, it can also avoid the mutual influence of the two excitation signals, so that the first radiator 110 can support the transmission of the first wireless signal or the second wireless signal in a circularly polarized manner together with the second radiator 120, the third radiator 130 and the floor 150, and the first radiator 110 can also support the third wireless signal in a linearly polarized manner. It should be noted that the electronic device 10 may also include two signal sources 140, and the two signal sources 140 are electrically connected to the combiner 180 so that the combiner 180 combines the first excitation signal and the second excitation signal provided by the two signal sources 140 into one path and transmits it to the first radiator 110. The embodiment of the present application does not limit the manner in which the first radiator 110 supports the first wireless signal and the third wireless signal. The first radiator 110 of the embodiment of the present application can support the first wireless signal or the second wireless signal in a circularly polarized manner, and can also support the third wireless signal in a linearly polarized manner. The first radiator 110 can be easily multiplexed with a conventional cellular antenna or Wi-Fi antenna in the related technology, which can simplify the structure of the electronic device 10 and achieve a miniaturized design.

[0098] Based on the structure of the electronic device 10, please refer to Fig.11 , Fig.11This is a fifth structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may further include a display screen 200, a middle frame 300, a circuit board 400, a battery 500 and a rear housing 600.

[0099] The display screen 200 can be mounted on the middle frame 300 and connected to the rear case 600 through the middle frame 300 to form a display surface of the electronic device 10. The display screen 200 can be used to display information such as images and texts. The display screen 200 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.

[0100] The middle frame 300 may include a frame 310 and a middle plate 320, and the middle plate 320 may provide support for the electronic devices in the electronic device 10. The frame 310 is connected to the edge of the middle plate 320 and protrudes from the middle plate 320. The frame 310 and the middle plate 320 form an accommodation space, and the electronic devices in the electronic device 10 may be installed and fixed in the accommodation space.

[0101] The circuit board 400 can be mounted on the middle frame 300. The circuit board 400 can be the mainboard of the electronic device 10. Among them, the circuit board 400 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 200 can be electrically connected to the circuit board 400 to control the display of the display screen 200 through the processor on the circuit board 400. It can be understood that the signal source 140 can be arranged on the circuit board 400. Of course, the signal source 140 can also be arranged on other carrier boards of the electronic device 100. The specific setting position of the signal source 140 is not limited in the embodiment of the present application.

[0102] The battery 500 may be mounted on the middle frame 300. At the same time, the battery 500 is electrically connected to the circuit board 400 so that the battery 500 can power the electronic device 10. A power management circuit may be provided on the circuit board 400. The power management circuit is used to distribute the voltage provided by the battery 500 to various electronic devices in the electronic device 10.

[0103] The rear case 600 may be connected to the middle frame 300, such as the frame 310. The rear case 600, the middle frame 300 and the display screen 200 may seal the electronic devices and functional components of the electronic device 10 inside the electronic device 10 to protect the electronic devices and functional components of the electronic device 10.

[0104] It is understandable that when the middle plate 320 of the middle frame 300 is made of a conductive material, part or all of the middle plate 320 can form the floor 150 of the electronic device 10. At this time, the middle plate 320 can not only carry the devices of the electronic device 10 but also serve as a grounding device. The middle plate 320 can be reused, and the electronic device 10 can be miniaturized. Of course, the floor 150 can also be set at other locations of the electronic device 10. For example, but not limited to, the floor 150 can be formed on structures such as the circuit board 400 and the back shell 600, or the floor 150 can also be set on the electronic device 10 and stacked with the circuit board 400, the middle plate 320, and the back shell 600. The specific structure of the floor 150 is not limited in the embodiment of the present application.

[0105] Among them, please refer to Fig.12 , Fig.12 A sixth structural diagram of the electronic device 10 provided in an embodiment of the present application. When the frame 310 of the middle frame 300 is made of a conductive material, a plurality of slits may be provided on the frame 310 to form a first metal branch 301, a second metal branch 302, and a third metal branch 303. The first radiator 110 may include the first metal branch 301, the second radiator 120 may include the second metal branch 302, and the third radiator 130 may include the third metal branch 303.

[0106] It can be understood that when three radiators are formed on the frame 310 and the middle plate 320 is reused as the floor 150, the first radiator 110, the second radiator 120, and the third radiator 130 can be grounded by electrically connecting to the floor 150 through, but not limited to, metal connecting ribs, metal springs, etc., and the embodiments of the present application are not limited to this.

[0107] The first radiator 110 to the third radiator 130 of the embodiment of the present application are formed on the middle frame 300 of the electronic device 10. The electronic device 10 can reuse the frame 310 as a radiator, and can achieve a miniaturized design of the electronic device 10. At the same time, the return path between the radiator formed on the frame 310 and the floor 150 formed on the middle plate 320 is also short, and the layout of the electronic device 10 is simpler.

[0108] It should be noted that at least one of the first radiator 110, the second radiator 120, and the third radiator 130 in the embodiment of the present application may not be formed on the frame 310. For example, but not limited to, at least one radiator may be arranged on a carrier such as an antenna bracket or a circuit board 400. The embodiment of the present application does not limit the specific setting positions of the first radiator 110, the second radiator 120, and the third radiator 130.

[0109] Please combine Fig.12 Please also refer to Fig.13 and Fig.14 , Fig.13 A seventh structural diagram of the electronic device 10 provided in an embodiment of the present application is shown. Fig.14 The eighth structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 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 oppositely, the second frame 312 and the fourth frame 314 are arranged oppositely, 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 can be the long frame of the electronic device 10, and the second frame 312 and the fourth frame 314 can be the short frame of the electronic device 10.

[0110] It is understandable that if Fig.12 As shown, the second radiator 120 can be set on the first frame 311, the third radiator 130 can be set on the second frame 312, part of the first radiator 110 can be set on the first frame 311, and another part of the first radiator 110 can be set on the second frame 312, the first radiator 110 can form a bent structure, and the first radiator 110, the second radiator 120 and the third radiator 130 can be set at the corners of the first frame 311 and the second frame 312 of the electronic device 10.

[0111] It is understandable that at least two of the first radiator 110, the second radiator 120 and the third radiator 130 may also be disposed on the same frame, such as the first frame 311 or the second frame 312. Fig.13 As shown, the first radiator 110, the second radiator 120 and the third radiator 130 can all be arranged on the longer first frame 311, and the three radiators can be arranged in the middle area of ​​the first frame 311, so that the electronic device 10 is not easily held by the user's hand when in the horizontal screen state. Fig.14 As shown, when the second frame 312 is the top frame of the electronic device 10 set vertically, the first radiator 110, the second radiator 120 and the third radiator 130 can also be set on the shorter second frame 312, so that the electronic device 10 is not easily held by the user's hand when it is in a vertical one-handed holding state.

[0112] Understandably, please combine Figure 6 , Figure 12 to Figure 14The rear shell 600 includes a central axis L0, which can be parallel to the first frame 311, so that the central axis L0 can extend along the direction where the long frame of the electronic device 10 is located, and the central axis L0 can be perpendicular to and equal to the second frame 312. Figure 6 As shown, the overlapping area of ​​the maximum beam when the electronic device 10 supports the first wireless signal and the maximum beam when supporting the second wireless signal can be at an angle of approximately 45 degrees with the central axis L0 (for example, the angle can be in the range of 30 degrees to 60 degrees), and the overlapping area of ​​the maximum beam when the electronic device 10 supports the first wireless signal and the maximum beam when supporting the second wireless signal can be in a direction of about 45 degrees above the rear shell 600, which is suitable for product applications of the electronic device 10.

[0113] It should be noted that the above is merely an exemplary description of the first radiator 110 , the second radiator 120 , and the third radiator 130 being disposed on the frame 310 , and the embodiment of the present application does not limit the specific arrangement positions of the three radiators.

[0114] Among them, please refer to Fig.15 , Fig.15 This is a ninth structural diagram of the electronic device 10 provided in an embodiment of the present application. The electronic device 10 may further include a detection module 700 and a processing module 800.

[0115] The detection module 700 can detect the current posture of the electronic device 10, the processing module 800 can be electrically connected to the detection module 700, and the processing module 800 can be electrically connected to the signal source 140, the first adjustment circuit 160, and the second adjustment circuit 170 of the electronic device 10. The processing module 800 can control the states of the signal source 140, the first adjustment circuit 160, and the second adjustment circuit 170 according to the current posture detected by the detection module 700, so that the electronic device 10 supports the first wireless signal in the first circular polarization mode or in the second circular polarization mode, and supports the second wireless signal in the third circular polarization mode or in the fourth circular polarization mode. In addition, the processing module 800 can also control the states of the signal source 140, the first adjustment circuit 160, and the second adjustment circuit 170 according to the current posture detected by the detection module 700, so that the main circular polarization radiation beam of the first wireless signal can be moved away from the user and the main circular polarization radiation beam away from the user can support the first wireless signal in a first circular polarization manner or in a second circular polarization manner; and the main circular polarization radiation beam of the second wireless signal can be moved away from the user and the main circular polarization radiation beam away from the user can support the first wireless signal in a third circular polarization manner or in a fourth circular polarization manner.

[0116] For example, in the initial state, the first adjustment circuit 160 of the electronic device 10 is grounded through the capacitive load branch 162 so that the main circular polarization radiation beam of the electronic device 10 when supporting the first wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode matching that of the satellite; the first adjustment circuit 160 is grounded through the inductive load branch 161 so that the main circular polarization radiation beam of the electronic device 10 when supporting the first wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode opposite to that of the satellite; then, when the detection module 700 detects that the electronic device 10 is in the head-hand state, the electronic device 10 can control the first adjustment circuit 160 to be grounded through the capacitive load branch 162, so that the circular polarization mode of the electronic device 10 when supporting the first wireless signal can match the circular polarization mode of the satellite. On the contrary, if in the initial state, the first adjustment circuit 160 is grounded through the capacitive load branch 162 so that the main circular polarization radiation beam of the electronic device 10 when supporting the first wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode opposite to the circular polarization mode of the satellite; the first adjustment circuit 160 is grounded through the inductive load branch 161 so that the main circular polarization radiation beam of the electronic device 10 when supporting the first wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode matching that of the satellite; then when the detection module 700 detects that the electronic device 10 is in the head and hand state, the electronic device 10 can control the first adjustment circuit 160 to be grounded through the inductive load branch 161, so that the circular polarization mode of the electronic device 10 when supporting the first wireless signal can match the circular polarization mode of the satellite.

[0117] For another example, in the initial state, the second adjustment circuit 170 of the electronic device 10 is grounded through the inductive load branch so that the main circular polarized radiation beam of the electronic device 10 when supporting the second wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode matching that of the satellite; the second adjustment circuit 170 is grounded through the capacitive load branch so that the main circular polarized radiation beam of the electronic device 10 when supporting the second wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode opposite to that of the satellite; then when the detection module 700 detects that the electronic device 10 is in the head and hand state, the electronic device 10 can control the second adjustment circuit 170 to be grounded through the inductive load branch so that the circular polarization mode of the electronic device 10 when supporting the second wireless signal can match the circular polarization mode of the satellite. On the contrary, if in the initial state, the second adjustment circuit 170 is grounded through the inductive load branch so that the main circular polarization radiation beam of the electronic device 10 when supporting the second wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode opposite to the circular polarization mode of the satellite; the second adjustment circuit 170 is grounded through the capacitive load branch so that the main circular polarization radiation beam of the electronic device 10 when supporting the second wireless signal is oriented in the direction of the rear shell 600 and has a circular polarization mode matching that of the satellite; then when the detection module 700 detects that the electronic device 10 is in the head and hand state, the electronic device 10 can control the second adjustment circuit 170 to be grounded through the capacitive load branch so that the circular polarization mode of the electronic device 10 when supporting the second wireless signal can match the circular polarization mode of the satellite.

[0118] It can be understood that the detection module 700 can be, but is not limited to, an electromagnetic wave absorption ratio (Specific Absorption Rate, referred to as SAR) detection circuit. The detection module 700 can detect the SAR value of the electronic device 10 to determine whether the electronic device 10 is in the head-hand state. If it is in the head-hand state, the processing module 800 can control the state of the first adjustment circuit 160 and the second adjustment circuit 170. Of course, the detection module 700 can also be other structures. For example, but not limited to, the detection module 700 can include components such as a gyroscope and a proximity sensor, so that the detection module 700 can also detect the current posture of the electronic device 10. The embodiment of the present application does not limit the specific structure of the detection module 700.

[0119] It can be understood that, in addition to detecting that the electronic device 10 is in the head-hand state, the detection module 700 can also detect whether the display screen 200 or the back shell 600 of the electronic device 10 is facing the satellite. For example, the detection module 700 can include, but is not limited to, components such as a gyroscope, an accelerometer, and an electronic compass. When the reference plane M0 in the aforementioned embodiment is the back shell surface of the electronic device 10, when the satellite transmits and receives signals in the first circular polarization mode, if the detection module 700 detects that the back shell surface of the electronic device 10 is facing the satellite, the processing module 800 can control the first adjustment circuit 160 to turn on the corresponding load branch, so that the first radiation section 115, the second radiator 120 and the floor 150 can support the transmission of the first wireless signal in the first circular polarization mode; when the detection module 700 detects that the display surface of the electronic device 10 is facing the satellite, the control module can control the first adjustment circuit 160 to turn on another corresponding load branch, so that the first radiator 110, the second radiator 120 and the floor 150 can support the transmission of the first wireless signal in the second circular polarization mode. The embodiments of the present application do not limit the specific control logic of the detection module 700 and the control module. Similarly, when the satellite transmits and receives signals in the third circular polarization mode, if the detection module 700 detects that the rear shell of the electronic device 10 is facing the satellite, the processing module 800 can control the second adjustment circuit 170 to turn on the corresponding load branch, so that the second radiation section 116, the third radiator 130 and the floor 150 can support the transmission of the second wireless signal in the third circular polarization mode; when the detection module 700 detects that the display surface of the electronic device 10 is facing the satellite, the control module can control the second adjustment circuit 170 to turn on another corresponding load branch, so that the second radiation section 116, the third radiator 130 and the floor 150 can support the transmission of the second wireless signal in the fourth circular polarization mode. The embodiments of the present application do not limit the specific control logic of the detection module 700 and the control module.

[0120] It can be understood that when the satellite transmitted signal and the received signal adopt different circular polarization methods, the first adjustment circuit 160 and the second adjustment circuit 170 can control the electronic device 10 to receive the signal transmitted by the satellite in a circular polarization method that matches the circular polarization method of the satellite transmitted signal, and the first adjustment circuit 160 and the second adjustment circuit 170 can also control the electronic device 10 to transmit a signal to the satellite in a circular polarization method that matches the circular polarization method of the satellite received signal.

[0121] For example, if the satellite transmits a signal in a first circular polarization direction and receives a signal in a second circular polarization direction, and the reference plane M0 in the aforementioned embodiment is the rear shell surface of the electronic device 10, if the user holds the electronic device 10, at this time, the first adjustment circuit 160 can control one or more inductive load branches 161 to be grounded, and the signal source 140 can excite the electronic device 10 to receive the satellite's transmission signal in the first circular polarization mode relative to the reference plane M0, so as to match the circular polarization mode of the satellite transmission signal. The first adjustment circuit 160 can also control one or more capacitive load branches 162 to be grounded, and the signal source 140 can excite the electronic device 10 to transmit a signal to the satellite in the second circular polarization mode relative to the reference plane M0, so as to match the circular polarization mode of the satellite reception signal. It can be understood that when the satellite transmits a signal in the second circular polarization direction and receives a signal in the first circular polarization direction, the first adjustment circuit 160 can take the opposite control operation to the above, which is not limited here. It can be understood that the adjustment method of the second adjustment circuit 170 can refer to the adjustment method of the first adjustment circuit 160, which is not described in detail here.

[0122] It is understandable that the processing module 800 may be a main control module of the electronic device 10, for example but not limited to the processing module 800 may be a processor. The processing module 800 may control the electronic device 10 to support the transmission of the first wireless signal and the second wireless signal in different circular polarization modes. The embodiment of the present application does not limit the structure of the processing module 800.

[0123] The electronic device 10 of the embodiment of the present application can detect whether the electronic device 10 is in a head-hand state through the detection module 700 when the user makes or receives a satellite call, and can make the main circular polarization beam of the electronic device 10 supporting the first wireless signal and the second wireless signal face the side where the back shell 600 is located and match the circular polarization mode of the satellite. On the one hand, the main circular polarization beam can be away from the side where the human head is located, which can avoid the decrease in the gain of the circular polarization beam due to the occlusion of the head and hands; on the other hand, the electronic device 10 matches the circular polarization mode of the satellite, which can ensure the radiation performance of the electronic device 10.

[0124] It should be noted that the above is only an exemplary description of the electronic device 10 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.

At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as limiting the present application.
