Description

Technical Field

[0001] This application relates to the field of wireless radio frequency technology, and more particularly to an antenna enhancer and a communication device. Background Technology

[0002] Electronic devices have communication capabilities. They use wire antennas to radiate wireless signals to enable wireless communication between the electronic device and other communication terminals, base stations, or satellites.

[0003] Currently, when electronic devices communicate wirelessly with satellites, the linear antennas of these devices generally only support linear polarization, making it difficult to efficiently exchange signals with satellites. Summary of the Invention

[0004] This application provides an antenna enhancer and a communication device for realizing circular polarization of wireless signals.

[0005] In a first aspect, this application provides a communication device, the communication device including an electronic device and an antenna enhancer, the electronic device having a linear antenna formed on a metal frame; the antenna enhancer including a metal body located on one side of the electronic device, the metal body being spaced apart from the linear antenna, the metal body being coupled to the linear antenna, the length direction of the metal body forming an angle greater than 0 and less than 180° with the width direction of the electronic device.

[0006] In this scheme, the metal body forms an angle greater than 0 and less than 180° with the width direction of the electronic device along its length. The metal body is coupled to the linear antenna of the electronic device. The linear antenna generates an electric field flowing along the width direction of the electronic device, and the metal body generates an electric field flowing along its length direction. The interaction between the metal body and the linear antenna generates electric field components in two orthogonal directions. Taking the width direction of the electronic device as the X-axis and the thickness direction as the Y-axis as an example, after coupling with the linear antenna, the electric field generated by the metal body has components in both the X-axis and Y-axis directions. The linearly polarized signal generated by the linear antenna and the linearly polarized signal generated by the metal body can be combined to form a circularly polarized (CP) signal, which can significantly improve the communication efficiency between the electronic device and other communication terminals, base stations, or satellites. Because the metal body is coupled to the linear antenna, and the linearly polarized signal generated by the metal body and the linearly polarized signal generated by the linear antenna can be combined to form a circularly polarized signal, the antenna enhancer does not require a feeding structure, making the antenna enhancer simple in structure, easy to assemble, and portable.

[0007] In conjunction with the first aspect, in one feasible implementation, the metal body adopts a patch structure, the metal body occupies a small space, the projection of the metal body along the height direction of the electronic device is rectangular, the patch structure of the metal body is conducive to generating a concentrated electric field, and the direction of the electric field generated by the metal body is along the length direction of the metal body.

[0008] In conjunction with the first aspect, in one feasible implementation, the plane formed by the width direction of the metal body and the thickness direction of the electronic device is parallel, which facilitates the coupling of the metal body with the linear antenna and can improve the gain of the communication device radiating circularly polarized signals.

[0009] In conjunction with the first aspect, in one feasible implementation, the phase difference between the electric field generated by the metallic body and the electric field generated by the wire antenna is: α is the angle formed by the length direction of the metal body and the width direction of the electronic device. When When the components of the combined electric field generated by the coupling of the metal body and the wire antenna are equal in two mutually orthogonal directions, it is beneficial to realize the circular polarization signal generated by the metal body and the wire antenna and reduce the axial ratio of the circular polarization signal generated by the metal body and the wire antenna.

[0010] In conjunction with the first aspect, in one feasible implementation, α is an obtuse angle. Generally, the electric field amplitude generated by the metal body will be smaller than that generated by the linear antenna 110. Taking the width direction of the electronic device as the X-axis and the thickness direction of the electronic device as the Y-axis, the Y-axis component of the electric field amplitude generated by the metal body will also be smaller than that generated by the linear antenna. The Y-axis component of the electric field generated by the metal body is... The component of the electric field generated by the metallic body along the X-axis is: When α is an obtuse angle, If the value is negative, then the combined electric field component of the metal body in the X-axis direction and the electric field of the wire antenna in the X-axis direction will actually decrease, and the combined electric field component E of the metal body and the wire antenna in the X-axis direction will become smaller. x The magnitude of (the component of the combined electric field in the X-axis direction) and E y The amplitudes of the combined electric field components along the Y-axis will be relatively close, which is beneficial for the metal body and the wire antenna to work together to achieve circular polarization of the wireless signal.

[0011] In conjunction with the first aspect, in one feasible implementation, α is between 120° and 160°, causing the combined electric field component E of the metal body and the wire antenna on the X-axis to be... x The magnitude of (the component of the combined electric field in the X-axis direction) and E yThe amplitudes of the combined electric field components along the Y-axis will be relatively close, which is beneficial for the coupling between the metal body and the wire antenna. For example, if α is an obtuse angle less than 120°, the metal body and the wire antenna are nearly perpendicular, which impairs the coupling performance between the metal body and the wire antenna. If α is an obtuse angle greater than 160°, the component of the electric field generated by the metal body along the Y-axis (the width direction of the electronic device) will be too small, which will impair the performance of the communication device in radiating wireless signals.

[0012] In conjunction with the first aspect, in one feasible implementation, the distance between the metal body and the linear antenna is 1mm-15mm. By controlling the distance between the metal body and the linear antenna, the phase difference between the electric field generated by the metal body and the electric field generated by the linear antenna can be controlled. Given a fixed α, this allows... This ensures that the components of the combined electric field generated by the coupling of the metal body and the wire antenna are equal in two mutually orthogonal directions, which is beneficial for the metal body and the wire antenna to cooperate in achieving circular polarization of wireless signals.

[0013] In conjunction with the first aspect, in one feasible implementation, the combined electric field generated by the metal body and the wire antenna forms an electric field component in the length direction of the electronic device, and the combined electric field generated by the metal body and the wire antenna forms an electric field component in the thickness direction of the electronic device. The amplitude of the electric field component in the length direction of the electronic device is equal to the amplitude of the electric field component in the thickness direction of the electronic device. This allows the linearly polarized signal radiated by the metal body and the linearly polarized signal radiated by the wire antenna to form an ideal circularly polarized signal, the axial ratio of which is 0.

[0014] In conjunction with the first aspect, in one feasible implementation, the antenna enhancer is in an assembled state, and the antenna enhancer further includes a plurality of metal side plates connected in a circle and surrounding the linear antenna. The metal body is insulated from at least a portion of the plurality of metal side plates. The plurality of metal side plates can confine the electric field generated by the linear antenna within the space surrounded by the plurality of metal side plates, thereby improving the gain of the linear antenna and the gain of the metal body, and further improving the gain of the circularly polarized signal generated by the combination of the electronic device and the antenna enhancer.

[0015] In conjunction with the first aspect, one feasible implementation further includes an insulating plate connected to and supported by one end of the plurality of metal side plates, the plurality of metal side plates surrounding the insulating plate, and the metal body disposed on the insulating plate. The insulating plate serves to support the metal body and also enables electrical isolation between the metal body and the metal side plates.

[0016] In conjunction with the first aspect, in one feasible implementation, the antenna enhancer further includes a metal base plate spaced apart from the insulating plate, a plurality of metal side plates surrounding the metal base plate, and one end of each of the plurality of metal side plates, away from the insulating plate, connected to the metal base plate. The metal base plate has an opening for a metal frame of the electronic device to extend into the antenna enhancer, and the metal frame is in contact with at least one of the plurality of metal side plates and the metal base plate. When the metal frame is in contact with at least one of the plurality of metal side plates and the metal base plate, the electric field generated by the linear antenna can be confined to the metal side plates, preventing the electric field generated by the linear antenna from flowing to the ground of the electronic device, thereby improving the gain of the circularly polarized signal generated by the coupling between the metal body and the linear antenna.

[0017] In conjunction with the first aspect, in one feasible implementation, the antenna enhancer further includes a metal patch coupled to the linear antenna. The metal patch is disposed on the insulating plate, spaced apart from the metal body, and also spaced apart from the linear antenna. The coupling between the metal patch and the linear antenna can also generate an electric field. The placement of the metal patch on the insulating plate allows for a more uniform distribution of the electric field generated by the linear antenna, which is beneficial for improving the gain of the coupling between the metal body and the linear antenna to generate a circularly polarized signal.

[0018] In conjunction with the first aspect, in one feasible implementation, the number of metal patches is two, the two metal patches are spaced apart, and the metal body is disposed between the two metal patches.

[0019] In conjunction with the first aspect, in one feasible implementation, the antenna enhancer has a folded state. The insulating plate is detachably connected to the plurality of metal side plates, and each metal side plate is hinged to the outer peripheral edge of the metal base plate. When the antenna enhancer is in the folded state, each metal side plate is folded to the metal base plate, and the insulating plate is stacked on the side of the plurality of metal side plates facing away from the metal base plate. The antenna enhancer folds into a thin sheet structure, and switching the antenna enhancer from the assembled state to the folded state greatly reduces its size, making it easier to carry and store.

[0020] In conjunction with the first aspect, in one feasible implementation, the antenna booster further includes a mounting bracket disposed within the space surrounded by the plurality of metal side plates, the mounting bracket being connected to at least a portion of the plurality of metal side plates, the mounting bracket being used to restrict the position of the electronic device extending into the antenna booster.

[0021] In conjunction with the first aspect, in one feasible implementation, the mounting bracket includes a first stop, a second stop, and a third stop. The first stop, the second stop, and the third stop all extend along the width direction of the electronic device. Both ends of the first stop, the second stop, and the third stop are connected to the plurality of metal side plates. The first stop, the second stop, and the third stop are located between the insulating plate and the metal base plate. The first stop and the second stop are spaced apart. The third stop is located on the side of the gap between the first stop and the second stop away from the metal base plate. The metal frame of the electronic device extends into the gap between the first stop and the second stop, and the third stop is used to abut against the metal frame.

[0022] Secondly, this application discloses an antenna enhancer for mounting to an electronic device, the electronic device having a linear antenna formed on a metal frame; the antenna enhancer includes a metal body located on one side of the electronic device, the metal body being spaced apart from the linear antenna, the metal body being coupled to the linear antenna, and the length direction of the metal body forming an angle greater than 0 and less than 180° with the width direction of the electronic device.

[0023] In this scheme, the metal body forms an angle greater than 0 and less than 180° with the width direction of the electronic device along its length. The metal body is coupled to the linear antenna of the electronic device. The linear antenna generates an electric field flowing along the width direction of the electronic device, and the metal body generates an electric field flowing along its length direction. The interaction between the metal body and the linear antenna generates electric field components in two orthogonal directions. Taking the width direction of the electronic device as the X-axis and the thickness direction as the Y-axis as an example, after coupling with the linear antenna, the electric field generated by the metal body has components in both the X-axis and Y-axis directions. The linearly polarized signal generated by the linear antenna and the linearly polarized signal generated by the metal body can be combined to form a circularly polarized (CP) signal, which can significantly improve the communication efficiency between the electronic device and other communication terminals, base stations, or satellites. Because the metal body is coupled to the linear antenna, and the linearly polarized signal generated by the metal body and the linearly polarized signal generated by the linear antenna can be combined to form a circularly polarized signal, the antenna enhancer does not require a feeding structure, making the antenna enhancer simple in structure, easy to assemble, and portable.

[0024] In conjunction with the second aspect, in one feasible implementation, the metal body adopts a patch structure, and the projection of the metal body along the height direction of the electronic device is rectangular.

[0025] In conjunction with the second aspect, in one feasible implementation, the antenna enhancer is in an assembled state, and the antenna enhancer further includes a plurality of metal side plates connected in a circle and surrounding the linear antenna, the metal body being insulated from at least a portion of the plurality of metal side plates.

[0026] In conjunction with the second aspect, in one feasible implementation, the antenna enhancer further includes an insulating plate connected to one end of the plurality of metal side plates and supported by the plurality of metal side plates, the plurality of metal side plates surrounding the insulating plate, and the metal body disposed on the insulating plate.

[0027] In conjunction with the second aspect, in one feasible implementation, the antenna enhancer further includes a metal base plate spaced apart from the insulating plate, the plurality of metal side plates surrounding the metal base plate, and one end of the plurality of metal side plates away from the insulating plate being connected to the metal base plate, the metal base plate having an opening for the metal frame of the electronic device to extend into the antenna enhancer.

[0028] In conjunction with the second aspect, in one feasible implementation, the antenna enhancer further includes a mounting bracket disposed within the space surrounded by the plurality of metal side plates. The mounting bracket is connected to at least a portion of the plurality of metal side plates, and the mounting bracket is used to restrict the position of the electronic device extending into the antenna enhancer.

[0029] In conjunction with the second aspect, in one feasible implementation, the mounting bracket includes a first stop, a second stop, and a third stop. The first stop, the second stop, and the third stop all extend along the width direction of the electronic device. Both ends of the first stop, the second stop, and the third stop are connected to the plurality of metal side plates. The first stop, the second stop, and the third stop are located between the insulating plate and the metal base plate. The first stop and the second stop are spaced apart. The third stop is located on the side of the gap between the first stop and the second stop away from the metal base plate. The metal frame of the electronic device extends into the gap between the first stop and the second stop, and the third stop is used to abut against the metal frame. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0064] This application discloses a communication device, which includes an antenna booster (AB) and an electronic device, the electronic device having communication functions. The electronic device includes, but is not limited to, cell phones, flip phones, notebook computers, tablet personal computers, laptop computers, personal digital assistants, or wearable devices.

[0065] For ease of understanding, we define the width direction of an electronic device as the X-axis, the thickness direction as the Y-axis, and the length direction as the Z-axis.

[0066] Please see Figure 1a , Figure 1b and Figure 1c The electronic device 100 includes a wire antenna 110 formed on a metal frame 100a. The wire antenna 110 is capable of radiating linearly polarized (LP) signals. When radiating LP signals, the wire antenna 110 generates an electric field, the direction of which is aligned with the width direction (X-axis direction) of the electronic device 100. The electronic device 100 also includes a feed line connected to the wire antenna 110, and a ground plane 121 to which the wire antenna 110 can be connected.

[0067] In the embodiments provided in this application, the line antenna includes a line antenna body 111 and two branches 112. In the X-axis direction, the two branches are disposed on both sides of the line antenna body 111, and each branch 112 has a gap 113 with the line antenna body 111.

[0068] In the embodiments provided in this application, the line antenna 110 may also have multiple grounding points. The line antenna 110 can be connected to the ground plane 121 or other potential reference points through the grounding points to adjust the resonant frequency, impedance matching, and other performance characteristics of the line antenna 110. The line antenna 110 also has a feed point, which is connected to the feed line 130. The electronic device 100 has a chip that feeds the line antenna 110 through the feed line 130. When the chip feeds the line antenna 110 through the feed line 130, the direction of the electric field generated by the line antenna 110 is consistent with the X-axis direction.

[0069] Please see Figure 2a and Figure 2b , Figure 2a A schematic diagram of the coupling structure between a metal body and a linear antenna in an electronic device in a communication device according to an embodiment of this application; Figure 2b for Figure 2a A top view. The antenna enhancer 200 includes a metal body 210 located on one side of the electronic device 100 along its length. The metal body 210 is spaced apart from the linear antenna 110 and coupled to it. The linear antenna 110 acts as a driving dipole, and the metal body 210 acts as a parasitic or driven dipole. The metal body 210 can also radiate linearly polarized (LP) signals. The direction of the electric field generated by the metal body 210 is consistent with its length direction. The linearly polarized signal generated by the linear antenna 110 and the linearly polarized signal generated by the metal body 210 combine to form a circularly polarized signal. The length direction of the metal body 210 forms an angle greater than 0° and less than 180° with the width direction of the electronic device 100.

[0070] The metal body 210 can be a patch structure, and the projection of the metal body 210 along the height direction of the electronic device 100 is rectangular. The metal body 210 is parallel to the plane formed by the width direction and the thickness direction of the electronic device 100. When the metal body 210 radiates a linearly polarized signal, the electric field generated by the metal body 210 has an electric field component along the X-axis and an electric field component along the Y-axis.

[0071] It should be noted that the parallelism between the metal body 210 and the plane formed by the width and thickness directions of the electronic device 100 does not imply absolute parallelism. A certain angular deviation is allowed between the metal body 210 and the plane formed by the width and thickness directions of the electronic device 100. For example, the deviation between the metal body 210 and the plane formed by the width and thickness directions of the electronic device 100 can be less than or equal to 10°. Specifically, the metal body 210 can have an angle of 5°, 8°, or 10° with the plane formed by the width and thickness directions of the electronic device 100.

[0072] In this application, the metal body 210 can be a thin sheet structure. When the metal body 210 radiates a linearly polarized signal, the direction of the electric field generated by the metal body 210 is parallel to the plane formed by the width direction and the thickness direction of the electronic device 100.

[0073] When achieving circular polarization of wireless signals using an antenna booster and the wire antenna of an electronic device, the antenna booster can be assembled with the electronic device, with a metal body spaced apart from the electronic device. The length direction of the metal body forms an angle greater than 0° and less than 180° with the width direction of the electronic device. In this case, the coupling between the metal body and the wire antenna can form a circularly polarized signal, thereby improving the communication efficiency between the electronic device and the satellite. In remote areas, mountainous regions, deserts, forests, or other wilderness environments where the electronic device cannot find a base station signal, assembling the antenna booster with the electronic device can enable efficient communication between the electronic device and the satellite.

[0074] In the embodiments provided in this application, when the linear antenna 110 of the electronic device 100 radiates a linearly polarized signal, the linear antenna 110 generates an electric field in the X-axis direction. Since the metal body 210 is coupled to the linear antenna 110, it can generate electric field components in both the X-axis and Y-axis directions. The electric field in the X-axis direction is orthogonal to the electric field in the Y-axis direction. The linearly polarized signal generated by the linear antenna 110 and the linearly polarized signal generated by the metal body 210 can be combined to form a circularly polarized (CP) signal, thereby significantly improving the communication efficiency between the electronic device 100 and other communication terminals, base stations, or satellites.

[0075] The metal body 210 is coupled to the linear antenna 110, and the linear polarization signal generated by the metal body 210 and the linear polarization signal generated by the linear antenna 110 can be combined to form a circular polarization signal. The antenna enhancer 200 does not need to be equipped with a feeding structure, which makes the structure of the antenna enhancer 200 simple, easy to assemble and carry.

[0076] In the embodiments provided in this application, the phase difference between the electric field generated by the metal body 210 and the electric field generated by the wire antenna 110 is . By making satisfy The ability to combine the linearly polarized signal generated by the linear antenna 110 and the linearly polarized signal generated by the metal body 210 to form a circularly polarized signal with an axial ratio bandwidth of less than 3dB is beneficial for improving the communication efficiency between the electronic device 100 and the satellite. Specifically, this can be achieved by adjusting the distance between the metal body and the electronic device.

[0077] In the embodiments provided in this application, E1 = ax. Where E1 is the electric field generated when the wire antenna 110 radiates a linearly polarized signal, and E2 is the electric field generated when the metal body 210 radiates a linearly polarized signal. The direction of E1 is along the positive X-axis, and the component of E2 on the X-axis is E 2x , The Y-axis component of E2 is

[0078] Where a and b are constants, and j is the imaginary unit. α is the phase difference between the electric field generated by the wire antenna 110 and the electric field generated by the metal body 210, and α is the angle between the direction of the electric field generated by the wire antenna 110 and the direction of the electric field generated by the metal body 210.

[0079] The combined electric field generated by the metal body 210 and the wire antenna 110 forms an electric field component along the length of the electronic device 100, and a combined electric field component along the thickness of the electronic device 100. The amplitudes of the electric field components along the length and thickness of the electronic device 100 are equal. In this case, the communication device can radiate an ideal circularly polarized signal. Specifically, the combined electric field component of E1 and E2 on the X-axis is E... x E x =E1+E 2x The combined electric field component of E1 and E2 on the Y-axis is E y E y =E 2y .

[0080] When a = b, In this case, E y =ae ±j(π-α) xsinα. When E x and E y When the amplitudes are the same, the linearly polarized signal radiated by the metal body 210 and the linearly polarized signal radiated by the wire antenna 110 can form an ideal circularly polarized signal, the axial ratio of which is 0.

[0081] It should be noted that E x and E y The amplitudes can be different, E x and E y When the amplitudes differ, the linearly polarized signal radiated by the metal body 210 and the linearly polarized signal radiated by the wire antenna 110 can also be combined to form a circularly polarized signal, at which point the axial ratio of the circularly polarized signal will be greater than 0.

[0082] In the embodiments provided in this application, the linear polarization signal generated by the linear polarization signal generated by the metal body 210 and the linear polarization signal generated by the metal body 210 can form a circular polarization signal, which can significantly improve the efficiency of communication between the electronic device 100 and the satellite, with a circular polarization gain improvement of up to 7dB. In remote areas, mountainous areas, deserts, forests, or other wilderness environments where the electronic device 100 cannot find a base station signal, the combination of the antenna enhancer 200 and the electronic device 100 can establish a reliable communication connection with the satellite. The electronic device 100 uses the antenna enhancer 200 to achieve circular polarization of the wireless signal, and the communication connection with the satellite enables functions such as calls, video, and text messages. In the event of a disaster or emergency rescue, the combination of the antenna enhancer 200 and the electronic device 100 (such as a mobile phone, watch, or other communication device) can maintain efficient communication with the satellite and provide timely rescue information. During scientific experiments or exploration missions, if the electronic device 100 cannot find a communication signal, the electronic device 100 can cooperate with the antenna enhancer 200 to establish a communication connection with the satellite.

[0083] In the embodiments provided in this application, α is an obtuse angle, but α can also be an acute angle. The metal body 210 is coupled to the linear antenna 110. Generally, without other intermediate devices for conversion, the electric field amplitude generated by the metal body 210 will be smaller than the electric field amplitude generated by the linear antenna 110. The electric field generated by the linear antenna 110 is along the positive X-axis, and the component of the electric field generated by the metal body 210 along the Y-axis is... The component of the electric field generated by the metal body 210 along the X-axis is: When α is an obtuse angle, The value is negative, so the combined electric field component E of E1 and E2 on the X-axis is negative. x The amplitude and E y The amplitudes will be relatively close, which is beneficial for the metal body 210 and the wire antenna 110 to work together to achieve circular polarization of the wireless signal.

[0084] In the embodiments provided in this application, α is between 120° and 160°. α can be 120°, 130°, 140°, 150° or 160°. This application does not impose any special limitation on the specific value of α.

[0085] In the embodiments provided in this application, the distance between the metal body 210 and the linear antenna 110 is 1mm-15mm. By controlling the distance between the metal body 210 and the linear antenna 110, the phase difference between the electric field generated by the metal body 210 and the electric field generated by the linear antenna 110 can be controlled. The distance between the metal body 210 and the linear antenna 110 can be 5mm or 8mm.

[0086] When using electronic device 100 in conjunction with antenna enhancer 200 to radiate circularly polarized signals, the reflection coefficient of line antenna 110 is simulated and tested. Line antenna 110 can be a line antenna 110 with parasitic branches. (See [link to relevant documentation]). Figure 3a and Figure 3b Within the 1.89GHz-2.2GHz frequency band, the reflection coefficient of the linear antenna 110 is less than -10dB, and the measurement data and simulation data are in excellent agreement.

[0087] Please see Figure 4a and Figure 4b , Figure 4a A schematic diagram showing the reflection coefficient and axial ratio of a communication device provided in an embodiment of this application; Figure 4b The radiation patterns of the communication device provided in one embodiment of this application are shown in the wide-side radiation patterns of the XOZ and YOZ coordinate planes. The metal body 210 and the wire antenna 110 are coupled in left-hand circular polarization (LHCP) on the XOZ coordinate plane, and in right-hand circular polarization (RHCP) on the YOZ coordinate plane. The metal body 210 and the wire antenna 110 are coupled in left-hand circular polarization (LHCP) on the YOZ coordinate plane, and in right-hand circular polarization (RHCP) on the YOZ coordinate plane. Please refer to... Figure 5a and Figure 5b Taking α equal to 140° as an example, Figure 5a A graph illustrating the mode saliency of a circularly polarized signal generated by a communication device provided in an embodiment of this application. Figure 5b This is a graph showing the mode phase of a circularly polarized signal generated by a communication device according to an embodiment of this application. The metal body and wire antenna are combined to form a single antenna. The Mode 1 and Mode 2 modes of the single antenna exhibit the highest saliency within the 1.5 GHz to 3 GHz frequency band. Figure 5aIn the diagram, Mode 1 characterizes the case where the wire antenna generates a strong electric field when the metal body is coupled to the wire antenna, Mode 2 characterizes the case where the metal body generates a strong electric field when coupled to the wire antenna, Mode 3 characterizes the case where the wire antenna generates a weak electric field when coupled to the metal body, and Mode 4 characterizes the case where the metal body generates a weak electric field when coupled to the wire antenna. It can be seen that the mode significance (MS) of Mode 1 peaks at 1.88 GHz, while the mode significance of Mode 2 peaks at 2.4 GHz. Between 2.2 GHz and 2.4 GHz, the phase difference between the mode phases of Mode 1 and Mode 2 is approximately 40°, and this phase difference is complementary to α. The metal body 210 and the wire antenna 110 work together to generate a wireless signal in the 2.2 GHz-2.4 GHz range, and this combination achieves high antenna efficiency.

[0088] Please refer to the embodiments provided in this application. Figure 6 (a) and (b) in the text, Figure 6 (a) in the figure is the simulated modal current distribution diagram when the metal body 210 is coupled to the wire antenna 110 at 1.88 GH. Figure 6 Figure (b) shows the simulated modal current distribution when the metal body 210 is coupled with the wire antenna 110 at 2.36 GHz. It can be seen that the metal body 210 and the wire antenna 110 have high antenna efficiency when generating a wireless signal of approximately 2.36 GHz. Figure 6 In (a) and (b), the arrows indicate the directions of the radiated currents in Mode 1 and Mode 2. Because the current on the metal body 210 in Mode 2 is relatively strong, the direction of the resulting equivalent radiated current deviates from the length direction of the metal body 210. Therefore, CP radiation can be achieved when the modes of Mode 1 and Mode 2 are close and their mode phase difference is slightly greater than 40°.

[0089] Please refer to the embodiments provided in this application. Figure 7a , Figure 7b and Figure 7cThe antenna enhancer 200 is in an assembled state and includes multiple metal side plates 220 connected in a circle around the linear antenna 110. The metal body 210 is insulated from at least a portion of the metal side plates 220. Because the multiple metal side plates 220 form a circle around the linear antenna 110, when the linear antenna 110 radiates a wireless signal within the space surrounded by the metal side plates 220, the multiple metal side plates 220 can confine the electric field generated by the linear antenna 110 within the space surrounded by the metal side plates 220. This improves the gain of the linear antenna 110 and the metal body 210, further enhancing the gain of the circularly polarized signal generated by the combination of the electronic device 100 and the antenna enhancer 200.

[0090] It should be noted that the metal side plate 220 can be an FR4 board (glass fiber epoxy resin copper clad laminate), a board with metal covering on its surface, or a board with metallization formed on its surface. The dielectric constant εr of the FR4 board is 4.4, and the loss factor tanδ of the FR4 board is 0.02. As long as the space surrounded by the multiple metal side plates 220 can reduce the back radiation of the linear antenna 110 and confine the electric field generated by the linear antenna 110 within the space surrounded by the multiple metal side plates 220, the specific type of the metal side plate 220 in this application is not limited.

[0091] The antenna enhancer 200 also includes an insulating plate 230, which is connected to one end of a plurality of metal side plates 220 and supported by the plurality of metal side plates 220. The plurality of metal side plates 220 surround the insulating plate 230, and a metal body 210 is disposed on the insulating plate 230.

[0092] The insulating plate 230 supports the metal body 210. Multiple metal side plates 220 are connected in a circle and connected to the insulating plate 230. The multiple metal side plates 220 surround the wire antenna 110, which not only confines the electric field generated by the wire antenna 110 within the space surrounded by the multiple metal side plates 220, but also supports the insulating plate 230 to facilitate coupling between the metal body 210 and the wire antenna 110. The insulating plate 230 can be made of insulating plastic, and the metal body 210 is insulated from the multiple metal side plates 220 through the insulating plate 230.

[0093] In the embodiments provided in this application, the antenna enhancer 200 further includes a metal base plate 240 spaced apart from the insulating plate 230, a plurality of metal side plates 220 surrounding the metal base plate 240, and one end of the plurality of metal side plates 220 away from the insulating plate 230 is connected to the metal base plate 240. The metal base plate 240 has an opening 241 for the metal frame 100a of the electronic device 100 to extend into the antenna enhancer 200, and the metal frame 100a is in contact with at least one of the plurality of metal side plates 220 and the metal base plate 240.

[0094] The antenna enhancer 200 is roughly a box-shaped structure, with an insulating plate 230, multiple metal side plates 220 and a metal base plate 240 forming a housing box, and a metal body 210 disposed on the side of the insulating plate 230 facing away from the metal base plate 240.

[0095] Please see Figure 8 (a), (b), (c), and (d) in the text. Figure 8 (a) is the electric field distribution diagram of the linear antenna provided in one embodiment of this application in the XOZ plane under case 1. Figure 8 (b) is the electric field distribution diagram of the XOZ plane of the wire antenna provided in an embodiment of this application under case 2. Figure 8 (c) in the figure is the electric field distribution diagram of the wire antenna provided in one embodiment of this application in the YOZ plane under case 1. Figure 8 (d) in the diagram shows the electric field distribution of the wire antenna in the YOZ plane in case 2 according to an embodiment of this application. The wire antenna 110 of the electronic device 100 extends into the housing. The metal base plate 240 can confine the electric field generated by the wire antenna 110 to the side of the metal base plate 240 near the insulating plate 230, thereby effectively suppressing the electric field propagating in the negative Z-axis direction of the wire antenna 110, thereby increasing the gain of the wire antenna 110, and further increasing the gain of the circularly polarized signal generated by the wire antenna 110 and the antenna enhancer 200. The metal body 210 is located on the side of the wire antenna 110 along the positive Z-axis direction.

[0096] Please refer to the embodiments provided in this application. Figure 9a , Figure 9b , Figure 9c and Figure 9dIn case 1, the reflection coefficient of the metal body 210 and electronic device 100 is between 1.86 GHz and 2.04 GHz, which is below -10 dB in the frequency band, while the axial ratio in the Z-axis direction is between 1.92 and 2.07 GHz, which is below 3 dB. Since the antenna enhancer 200 does not restrict the electric field of the linear antenna 110 in the negative Z-axis direction, the gain of the antenna enhancer 200 and electronic device 100 in radiating circularly polarized signals is low, even below 1 dBic. In case 2, however, the electric field generated by the linear antenna 110 is confined within the housing, effectively suppressing the electric field propagating in the negative Z-axis direction. This improves the gain of the antenna enhancer 200 and electronic device 100 in radiating circularly polarized signals, achieving a 5 dBic increase in gain for left-hand circular polarization (LHCP) in the positive Z-axis direction. When the antenna enhancer 200 and the electronic device 100 work together to radiate a circularly polarized signal, the impedance bandwidth (IBW) and axial ratio bandwidth (ARBW) are prone to misalignment.

[0097] In the embodiments provided in this application, in order to align the IBW and ARBW and further improve the gain of the circularly polarized signal generated by the electronic device 100 and the antenna enhancer 200, the antenna enhancer 200 further includes a metal patch 250 coupled to the linear antenna. The metal patch 250 is disposed on the insulating plate 230, spaced apart from the metal body 210, and spaced apart from the linear antenna 110. There are two metal patches 250, spaced apart, with the metal body 210 disposed between the two metal patches 250. The metal patch can be polygonal, specifically rectangular, triangular, trapezoidal, or irregular in shape; this application does not limit the specific shape of the metal patch.

[0098] In Prop, the 10 dB IBW generated by the combination of electronic device 100 and antenna enhancer 200 corresponds to 1.9 GHz-2.3 GHz, and the 3 dB ARBW generated by the combination of electronic device 100 and antenna enhancer 200 corresponds to 1.7 GHz-2.26 GHz. Due to the presence of two AR valleys at 1.82 GHz and 2.1 GHz, the ARBW is significantly increased.

[0099] Please refer to the embodiments provided in this application. Figure 10 , Figure 10 This is a schematic diagram of the vector current distribution with different phase differences between the electric field generated by the metal body and the electric field generated by the wire antenna, provided in an embodiment of this application. Figure 10In the above, the angle α between the direction of the electric field generated by the metal body 210 and the direction of the electric field generated by the wire antenna 110 is 140°, and the phase difference between the electric field generated by the metal body 210 and the electric field generated by the wire antenna 110 is... In α and When they are complementary or nearly complementary, the electric field generated by the interaction between the metal body 210 and the linear antenna 110 is stronger.

[0100] The antenna enhancer 200 also includes a mounting bracket 260 disposed within the space surrounded by a plurality of metal side plates 220. The mounting bracket 260 is connected to at least a portion of the plurality of metal side plates 220 and is used to limit the position of the electronic device 100 extending into the antenna enhancer 200.

[0101] The mounting bracket 260 can directly contact at least a portion of the multiple metal side plates 220. The mounting bracket 260 is located inside the housing. The mounting bracket 260 includes a first stop 261, a second stop 262, and a third stop 263. The first stop 261, the second stop 262, and the third stop 263 all extend along the width direction of the electronic device 100. Both ends of the first stop 261, the second stop 262, and the third stop 263 are connected to a plurality of metal side plates 220. The first stop 261, the second stop 262, and the third stop are located between the insulating plate 230 and the metal base plate 240. The first stop 261 and the second stop 262 are spaced apart. The third stop 263 is located on the side of the gap between the first stop 261 and the second stop 262 away from the metal base plate 240. The metal frame 100a of the electronic device 100 extends into the gap between the first stop 261 and the second stop 262. The third stop is used to abut against the metal frame 100a. The first stop 261, the second stop 262, and the third stop are all generally elongated structures. These three stops restrict the position of the electronic device 100 within the receiving box. The third stop 263 limits the extent to which the electronic device 100 can extend into the receiving box. The first stop 261 and the second stop 262 cooperate to limit the displacement of the electronic device 100 in the Y-axis direction. In the embodiments provided in this application, the first stop 261 can be made of insulating material, the second stop 262 can be made of metal, and the third stop 263 can be made of insulating material.

[0102] In the embodiments provided in this application, when the first block 261 and the second block 262 restrict the position of the electronic device 100, the electronic device 100 extends into the receiving box through the opening 241. The electronic device 100 divides the opening 241 into two slots, and the resonant electric field in the slots also affects the radiation characteristics. Please refer to [link to relevant documentation]. Figure 11 (a), (b), and (c) in the text. Figure 11Images (b) and (c) show the electric field amplitude distribution on the bottom plane of the back cavity at the AR valley. It can be seen that the slot resonates at 1.82 GHz, resulting in a strong electric field within the slot. Therefore, the AR valley at 1.82 GHz is caused by the openings of the wire antenna 110, the metal body 210, the parasitic metal, and the metal substrate 240. At 2.1 GHz, the resonance on both slots is weak, and the electric fields on the two slots are essentially equal. Therefore, the slots contribute very little to the radiation. Thus, the AR valley at 2.1 GHz is formed by the wire antenna 110, the metal body 210, and the metal patch 250.

[0103] Please refer to the embodiments provided in this application. Figure 12 Figures (a), (b), (c), and (d) show the vector current distribution of the metal body 210, metal patch 250, and wire antenna 110 in the AR valley when the proposed AB is communicating with electronic device 100. It can be seen that the current on metal body 210 is excited at both frequencies, and there is also current on metal patch 250. The current on wire antenna 110 is mainly concentrated near the feed point at 1.82 GHz, while at 2.1 GHz it is distributed across the entire metal frame 100a. At 1.82 GHz, the current on metal body 210 is 80° larger than the current on wire antenna 110, while at 2.1 GHz, the current phase difference is 50°. The phase difference at 2.1 GHz is close to the complementary angle (38°) between wire antenna 110 and metal body 210, while the phase difference at 1.82 GHz is slightly greater.

[0104] Please see Figure 13 (a), (b), (c) and (d) in the text, from Figure 13 As can be observed in (a) of case 2, due to the resonance of the metal body 210, the electric field is very strong when the direction of the electric field is aligned with the length direction of the metal body 210. Conversely, the electric field amplitude is relatively weak when the direction of the electric field is perpendicular to the length direction of the metal body 210. Please refer to [link to relevant documentation]. Figure 13 (b) Figure 13 (c) and Figure 13 In (d), the electric field across the radiating aperture becomes more uniform after the introduction of the metal patch 250. This is because an electric field is more easily established between the metal patch 250, the metal body 210, or the metal side plate 220. Therefore, the gain of the proposed AB is improved.

[0105] Please refer to the embodiments provided in this application. Figure 14a , Figure 14b , Figure 14cThe antenna enhancer 200 has an assembled state and a folded state, and the assembled state and the folded state of the antenna enhancer 200 can be switched between each other.

The antenna enhancer 200 can cooperate with the electronic device 100 to radiate circularly polarized signals.

For example, by adjusting L... c1 L c2 H c h, g, l1, l2, L p or W p The value can adjust the impedance bandwidth and axial ratio bandwidth of the circularly polarized signal generated by the metal body and the wire antenna.

The antenna enhancer 200 folds into a thin sheet structure. Switching the antenna enhancer 200 from the assembled state to the folded state greatly reduces its size, making it easier to carry and store.
