These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.
[0055] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.
[0056] In this application, circular polarization refers to an electromagnetic wave whose direction changes only with time, and whose trajectory, when projected onto a plane perpendicular to the propagation direction, forms a circle. Circular polarization is omnidirectional, resulting in minimal differences in antenna performance across different directions.
[0057] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0058] The first aspect of this application provides an antenna assembly, such as... Figure 1 As shown, the antenna assembly includes a first radiator 1 and a second radiator 2. An angle is formed between the first radiator 1 and the second radiator 2. The first radiator 1 and the second radiator 2 are rotatable relative to each other to change the size of the angle. When the angle is within a set range, the first radiator 1 and the second radiator 2 can form a circularly polarized antenna.
[0059] It is understood that the first radiator 1 and the second radiator 2 can radiate and receive signals to help the antenna assembly of this application achieve communication functions. The angle formed by the first radiator 1 and the second radiator 2 can be adjusted by rotation, which on the one hand facilitates the storage and use of the antenna assembly of this application, and on the other hand helps to form a circularly polarized antenna to generate circularly polarized waves.
[0060] In related technologies, when in outdoor or other environments without carrier signals, electronic devices can use satellites as relay stations to forward and reflect signals, thereby achieving communication. Electronic devices generally exhibit directionality when radiating and receiving signals through antenna components; the communication performance of the antenna components varies significantly in different directions, which makes establishing a connection between electronic devices and satellites somewhat difficult.
[0061] Currently, some technologies involve methods such as creating slots to increase the polarization component of electronic devices in a specific direction. However, this method can significantly damage the structure of the electronic device and reduce its waterproof performance. Adding components to increase the polarization component of the antenna assembly occupies internal space and makes it more susceptible to interference.
[0062] In this embodiment, circular polarization is achieved through a rotatable first radiator 1 and a second radiator 2. The antenna assembly of this application achieves omnidirectional signal radiation and reception without disrupting the structure of the electronic device. Furthermore, the first radiator 1 and the second radiator 2 can also serve as the housing of the electronic device, eliminating the need for internal placement and saving space. This reduces interference between components of the electronic device, thereby improving communication performance.
[0063] like Figure 1 As shown in the figure, the extensions of the first radiator 1 and the second radiator 2 both serve as sides of the included angle, and their intersection forms the vertex of the included angle. The included angle has the first radiator 1 as its initial side, rotates in a counterclockwise direction, and has the second radiator 2 as its final side.
[0064] In this embodiment, the first radiator 1 and the second radiator 2 generate a circularly polarized antenna by producing a current or magnetic current with a phase difference, thereby generating a circularly polarized wave. The first radiator 1 and the second radiator 2 can generate current or magnetic current through excitation. The first radiator 1 and the second radiator 2 can also generate current or magnetic current by coupling with other components. Specifically, the first radiator 1 and the second radiator 2 can be excited by the same component or coupled to the same component, or they can be excited by different components or coupled to different components.
[0065] In this embodiment, the first radiator 1 can generate current through electromagnetic effects by being close to a component with current. The second radiator 2 can also generate current through electromagnetic effects by being close to a component with current.
[0066] In this embodiment, the first radiator 1 and the second radiator 2 are jointly excited by a power divider to generate current.
[0067] In this embodiment, the first radiator 1 generates current through a power divider, and the second radiator 2 generates current through electromagnetic field coupling or current coupling.
[0068] In this embodiment, the second radiator 2 generates current through a power divider, and the first radiator 1 generates current through electromagnetic field coupling or current coupling.
[0069] In this embodiment, both the first radiator 1 and the second radiator 2 can rotate relative to each other, thereby adjusting the angle between them. The first radiator 1 can be fixed, while the second radiator 2 adjusts the angle by rotating around the first radiator 1. Alternatively, the second radiator 2 can be fixed, while the first radiator 1 adjusts the angle by rotating around the second radiator 2.
[0070] In this embodiment, the rotation axis of the first radiator 1 is the same as the rotation axis of the second radiator 2. Alternatively, the rotation axis of the first radiator 1 may be different from the rotation axis of the second radiator 2. The rotation axes of the first radiator 1 and the second radiator 2 can be skewed, parallel, or intersecting, as long as the first radiator 1 and the second radiator 2 are perpendicular to each other at a certain position during rotation.
[0071] In this embodiment, the first radiator 1 and the second radiator 2 can be driven by the same component to adjust the angle between them. Alternatively, the first radiator 1 and the second radiator 2 can be driven by different components to adjust the angle between them.
[0072] In this embodiment, the first radiator 1 and the second radiator 2 can rotate in the same direction to adjust the angle between them. Alternatively, the first radiator 1 and the second radiator 2 can rotate in opposite directions to adjust the angle between them.
[0073] like Figure 2 As shown in the figure, the antenna simulation efficiency diagram of the antenna assembly of this application is presented.
[0074] like Figure 3 As shown in the figure, the dashed line represents the relationship between radiation efficiency and frequency, and the solid line represents the relationship between total efficiency and frequency.
[0075] like Figure 4 As shown in the figure, the radiation pattern of the antenna assembly is viewed from above, and the data in the figure represents the total gain.
[0076] like Figure 5 As shown in the figure, the radiation pattern of the antenna assembly is viewed from above, and the data in the figure is the left-hand circular polarization gain.
[0077] like Figure 6As shown in the figure, the radiation pattern of the antenna assembly is viewed from above, and the data in the figure is the right-hand circular polarization gain.
[0078] In summary, the antenna assembly of this application can improve its communication performance by structurally facilitating the formation of conditions for a circularly polarized antenna.
[0079] In some embodiments of this application, such as Figure 1 As shown, the rotation axis of the first radiator 1 is the same as the rotation axis of the second radiator 2.
[0080] It is understandable that the first radiator 1 and the second radiator 2 have the same axis of rotation, which is beneficial for both to be driven by the same driving component, so as to achieve the adjustment of the included angle.
[0081] In this embodiment, the rotation axis of the first radiator 1 can extend along the length direction of the first radiator 1. The rotation axis of the first radiator 1 can extend along the width direction of the first radiator 1.
[0082] In this embodiment, the rotation axis of the second radiator 2 can extend along the length direction of the second radiator 2. The rotation axis of the second radiator 2 can extend along the width direction of the second radiator 2.
[0083] In some embodiments of this application, such as Figure 7 As shown, the rotation radius of the first radiator 1 is equal to the rotation radius of the second radiator 2.
[0084] It is understandable that having the same rotation radius for the first radiator 1 and the second radiator 2 facilitates the generation of fields with equal amplitude of current or magnetic current, which is beneficial for forming a circularly polarized antenna to generate circularly polarized waves. This improves the communication performance of the antenna assembly of this application.
[0085] In some embodiments of this application, such as Figure 8 As shown, the rotation radius of the first radiator 1 is not equal to the rotation radius of the second radiator 2.
[0086] It is understandable that having different radiators 1 and 2 makes it easier to arrange the antenna assembly of this application on the electronic device, thereby reducing the space occupied by the two to form an angle and improving the space utilization efficiency of the electronic device.
[0087] In some embodiments of this application, the first radiator 1 and the second radiator 2 are symmetrically arranged with respect to a plane of symmetry, which is located between the first radiator 1 and the second radiator 2, and the rotation axis of the first radiator 1 and the rotation axis of the second radiator 2 are both located within the plane of symmetry.
[0088] It is understandable that this arrangement is beneficial for the first radiator 1 and the second radiator 2 to form a perpendicular positional relationship when rotating, which is beneficial for the first radiator 1 and the second radiator 2 to form a circularly polarized antenna to generate circularly polarized waves, thereby improving the communication performance of the antenna assembly of this application.
[0089] In some embodiments of this application, the phase difference between the radiation signal of the first radiator 1 and the radiation signal of the second radiator 2 is 90°.
[0090] It is understandable that a circularly polarized antenna can be achieved by two perpendicular currents or magnetic currents with equal amplitude and a 90° phase difference. Therefore, setting the phase difference between the radiated signal of the first radiator 1 and the radiated signal of the second radiator 2 to 90° is beneficial for the first radiator 1 and the second radiator 2 to form a circularly polarized antenna and improve its circular polarization performance.
[0091] In the embodiments of this application, the radiation signal of the first radiator 1 can be the current flowing through the first radiator 1 or the magnetic current flowing through the first radiator 1.
[0092] In this embodiment of the application, the radiation signal of the second radiator 2 can be the current flowing through the second radiator 2 or the magnetic current flowing through the second radiator 2.
[0093] In some embodiments of this application, the current flowing through the first radiator 1 and the current flowing through the second radiator 2 need to have a phase difference. For example... Figure 9 As shown, the antenna assembly includes a feed section 3 and a phase shifter 4. The feed section 3 is electrically connected to the first radiator 1, and the feed section 3 is electrically connected to the second radiator 2 through the phase shifter 4. This helps to improve the accuracy of the phase difference between the first radiator 1 and the second radiator 2.
[0094] It is understandable that the feed unit 3 can generate current in both the first radiator 1 and the second radiator 2 by feeding them. The phase shifter 4 is electrically connected to the second radiator 2, which can change the phase of the current in the second radiator 2, thereby creating a phase difference between the current in the first radiator 1 and the current in the second radiator 2. This is beneficial for the first radiator 1 and the second radiator 2 to form a circularly polarized antenna.
[0095] Specifically, two currents with a phase difference can generate a circularly polarized wave when the first radiator 1 and the second radiator 2 rotate to an angle within a set range.
[0096] In some embodiments of this application, the current flowing through the first radiator 1 and the current flowing through the second radiator 2 need to be of equal amplitude in order to form circular polarization when the angle between them is within a set range. For example... Figure 9As shown, the antenna assembly includes a first matching component 5, and the feed section 3 is electrically connected to the first radiator 1 through the first matching component 5. This facilitates the matching of the current in the first radiator 1 with the current in the second radiator 2, so that the first radiator 1 and the second radiator 2 form a circularly polarized antenna.
[0097] It is understood that the feed unit 3, the first matching component 5, and the first radiator 1 form a loop. The first matching component 5 can adjust the voltage in the loop so that the current flowing through the first radiator 1 matches the current of the second radiator 2. This is beneficial for the first radiator 1 and the second radiator 2 to form a circularly polarized antenna when the rotation angle is within a set range, thereby improving the communication performance of the antenna assembly of this application.
[0098] In some embodiments of this application, such as Figure 9 As shown, the first matching component 5 includes a first capacitor 51 and a first inductor 52. The first capacitor 51 is connected to the power supply section 3 and the first radiator 1. One end of the first inductor 52 is connected between the first capacitor 51 and one end of the first radiator 1. The other end of the first inductor 52 and the other end of the first radiator 1 are both grounded.
[0099] It is understandable that the first inductor 52 and the first radiator 1 are connected in parallel, allowing for impedance adjustment in the circuit. The structure formed by the first inductor 52 and the first radiator 1 is connected in series with the first capacitor 51, which facilitates the first capacitor 51's impedance adjustment in the circuit. Through the impedance tuning effect of the first inductor 52 and the first capacitor 51, it is beneficial for the impedance of the circuit containing the first radiator 1 to match the impedance of the circuit containing the second radiator 2, thereby facilitating the formation of equal-amplitude currents or magnetic currents.
[0100] In some embodiments of this application, the current flowing through the second radiator 2 and the current flowing through the first radiator 1 need to have equal amplitude in order to form circular polarization when the angle between them is within a set range. For example... Figure 9 As shown, the antenna assembly includes a second matching component 6, and the feed section 3 is electrically connected to the second radiator 2 through the second matching component 6. This facilitates the matching of the current in the second radiator 2 with the current in the first radiator 1, so that the second radiator 2 and the first radiator 1 form a circularly polarized antenna.
[0101] It is understood that the feed unit 3, the second matching component 6, and the second radiator 2 form a loop. The second matching component 6 can adjust the voltage in the loop so that the current flowing through the second radiator 2 matches the current of the first radiator 1. This is beneficial for the second radiator 2 and the first radiator 1 to form a circularly polarized antenna when the rotation angle is within a set range, thereby improving the communication performance of the antenna assembly of this application.
[0102] In some embodiments of this application, such as Figure 9 As shown, the second matching component 6 includes a second capacitor 61 and a second inductor 62. The second capacitor 61 is connected to the power supply section 3 and the second radiator 2. One end of the second inductor 62 is connected between one end of the second capacitor 61 and one end of the second radiator 2. The other end of the second inductor 62 and the other end of the second radiator 2 are both grounded.
[0103] It is understandable that the second inductor 62 and the second radiator 2 are connected in parallel, allowing for impedance adjustment in the circuit. The structure formed by the second inductor 62 and the second radiator 2 is connected in series with the second capacitor 61, which facilitates the second capacitor 61's impedance adjustment in the circuit. Through the impedance tuning effect of the second inductor 62 and the second capacitor 61, the impedance of the circuit containing the second radiator 2 is matched with the impedance of the circuit containing the first radiator 1, thereby promoting the formation of equal-amplitude currents or magnetic currents.
[0104] In some embodiments of this application, the range of the set range is 70 to 110°.
[0105] It is understood that within the above-mentioned value range, enabling the first radiator 1 and the second radiator 2 to form a circularly polarized antenna to generate a circularly polarized wave is beneficial for the antenna assembly of this application to be arranged on electronic devices and to be compatible with other components of the electronic devices.
[0106] For example, taking a foldable screen phone as an example, the foldable screen phone can be hovered at multiple angles, and the rotation axis of the foldable screen phone when folded and unfolded is the same as that of the antenna assembly of this application. When the foldable screen phone is not hovering at 90°, the first radiator 1 and the second radiator 2 can still generate circularly polarized waves, which can still improve the communication performance of the foldable screen phone and is beneficial to improving the adaptability of the antenna assembly of this application.
[0107] In the embodiments of this application, the range of the set range can be 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105° or 110°, or other values between 70° and 110°.
[0108] In some embodiments of this application, such as Figure 11 As shown, the antenna assembly includes a signal input terminal 10 and a phase conversion unit 11. The signal input terminal 10 is connected to the second radiator 2. The phase conversion unit 11 is used to connect the first radiator 1 and the signal input terminal 10 so that the signal phase in the first radiator 1 and the signal phase in the second radiator 2 can be 90° out of phase.
[0109] In related technologies, the first radiator 1 and the second radiator 2 are generally fixed at specific positions on electronic devices and cannot move relative to the electronic devices. Therefore, when the first radiator 1 and the second radiator 2 form a circularly polarized antenna, their phases tend to remain relatively stable, that is, the signal phase of the first radiator 1 always leads the signal phase of the second radiator 2 by 90°, or always follows the signal phase of the second radiator 2 by 90°, which is not conducive to changing its polarization direction.
[0110] By adding a phase conversion unit 11, this application enables the signal phase of the first radiator 1 and the signal phase of the second radiator 2 to be changed according to actual needs, which is beneficial for switching between left-hand and right-hand circular polarization of the circularly polarized antenna.
[0111] In some embodiments of this application, such as Figure 11 As shown, the phase conversion unit 11 includes a conversion section 111, a first phase shifting section 112, and a second phase shifting section 113. The first phase shifting section 112 and the second phase shifting section 113 are respectively connected to the first radiator 1. The conversion section 111 can connect the first phase shifting section 112 and the signal input terminal 10 or connect the second phase shifting section 113 and the signal input terminal 10.
[0112] In this embodiment, when the conversion unit 111 turns on the first phase shifter 112 and the signal input terminal 10, the signal phase of the first radiator 1 leads the signal phase of the second radiator 2 by 90°. When the conversion unit 111 turns on the second phase shifter 113 and the signal input terminal 10, the signal phase of the second radiator 2 leads the signal phase of the first radiator 1 by 90°.
[0113] In the embodiments of this application, the first radiator 1 is generally fixed on the side where the processor of the electronic device is located, and the second radiator 2 is generally fixed on the other side.
[0114] like Figure 12 As shown, the circular polarization pattern of the signal phase of the second radiator 2 lags behind the first radiator by 190° is shown. The left figure is the left-hand circular polarization pattern, and the right figure is the right-hand circular polarization pattern.
[0115] like Figure 13 As shown, the circular polarization pattern when the signal phase of the second radiator 2 leads the first radiator by 190° is shown. The left figure is the left-hand circular polarization pattern, and the right figure is the right-hand circular polarization pattern.
[0116] In the embodiments of this application, the first phase shifter 112 and the second phase shifter 113 can be impedance lines.
[0117] Optionally, the conversion unit 111 is a switch.
[0118] A second aspect of this application provides an electronic device that includes an antenna assembly as described in the above embodiments.
[0119] It is understood that, due to the use of the antenna components of the above embodiments, the electronic device of this application has the same technical effects as the above embodiments, and will not be described again here.
[0120] In this embodiment of the application, the electronic device can be a smartphone, tablet computer, or other product with a screen 8.
[0121] In some embodiments of this application, such as Figure 10 As shown, the electronic device includes a rotating assembly 7. The first radiator 1 and the second radiator 2 are both connected to the rotating assembly 7. The rotating assembly 7 can drive the first radiator 1 and the second radiator 2 to rotate, so as to change the angle between them.
[0122] It is understood that by rotating the first radiator 1 and the second radiator 2, the rotation component 7 can change the angle between them, thereby forming a circularly polarized antenna and improving the communication performance of the electronic device of this application.
[0123] In this embodiment of the application, the rotating component 7 can drive the first radiator 1 and the second radiator 2 to rotate in the same direction to adjust the angle between them, or it can drive the first radiator 1 and the second radiator 2 to rotate in different directions to adjust the angle between them.
[0124] In some embodiments of this application, such as Figure 10 As shown, the electronic device includes a screen 8, and a rotating component 7 is connected to the screen 8 to enable the screen 8 to fold and unfold.
[0125] Understandably, the rotating component 7 facilitates the storage and use of the electronic device by folding and unfolding the screen 8. In addition to folding and unfolding the screen 8, the rotating component 7 can also rotate the first radiator 1 and the second radiator 2 to form a circularly polarized antenna, which helps to improve the structural compactness of the electronic device.
[0126] In this embodiment, the rotating component 7 can drive the screen 8 to rotate along its width direction to fold and unfold. The rotating component 7 can also drive the screen 8 to rotate along its length direction to fold and unfold.
[0127] In this embodiment, the rotating component 7 can drive the screen 8 to fold inward and unfold outward. "Inward" refers to the direction in which the two parts of the rotating component directly contact each other after the screen is folded.
[0128] In this embodiment, the rotating component 7 can drive the screen 8 to fold outward and unfold inward. Outward refers to the direction in which the two parts of the screen separate after the rotating component folds.
