[0033] Exemplary embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0034] The embodiments described below, which are examples of some of the embodiments of this disclosure, do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0035] Figure 1 This is a structural diagram of an antenna assembly according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the antenna assembly includes a radiating stub 110, a conductor 120, a switching device 130, and a feed stub 140.

[0036] Among them, the radiating stub 110 is the main component of the antenna assembly, responsible for generating radiated current and radiating electromagnetic waves.

[0037] The conductor 120 is a material with good electrical conductivity, used to assist the radiative branch 110 in forming the desired radiation mode. For example, the conductor 120 is a steel sheet.

[0038] Conductor 120 is parallel to radiating branch 110. For example... Figure 1 As shown, the conductor 120 and the radiating branch 110 are arranged parallel to each other along the second direction, and there is a gap between the conductor 120 and the radiating branch 130. In this embodiment of the present disclosure, there are a first direction, a second direction, and a third direction. The first direction can also be called the x-direction, the second direction can also be called the y-direction, and the third direction can also be called the z-direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0039] The feeding stub 140 is disposed between the radiating stub 110 and the conductor 120 for coupling and feeding the radiating stub 110 and the conductor 120. It can transmit energy from the signal source to the radiating stub and the conductor through the action of the electromagnetic field, thereby exciting the electromagnetic radiation of the radiating stub and the conductor.

[0040] A switching device 130 is disposed between the radiating stub 110 and the conductor 120 for connecting the radiating stub 110 and the conductor 120.

[0041] If the switching device 130 is in the ON state, the radiating stub 110 and the conductor 120 are connected, forming a rectangular structure. In this case, through the feeding stub 140, coupled feeding can excite an electromagnetic component along a third direction (perpendicular to both the first and second directions) and an electromagnetic component along the first direction, such as... Figure 2 and Figure 3 As shown.

[0042] in, Figure 2 This is a schematic diagram of the electromagnetic field distribution in the magnetically coupled pole mode according to an exemplary embodiment of the present disclosure. Figure 3 This is a schematic diagram of the electromagnetic field distribution in an electric dipole mode according to an exemplary embodiment of the present disclosure. Figure 2 In the diagram, the large black arrow indicates the direction of the current. The current flows along a circular path, which causes a change in the magnetic field, thus producing an electromagnetic component along a third direction (perpendicular to both the first and second directions). Figure 3 In the diagram, the large black arrow indicates the direction of the voltage gradient, which is the direction of the electric field, thus generating an electromagnetic component along the first direction.

[0043] Therefore, when the radiating stub 110 and the conductor 120 are connected, they can be coupled and fed through the feeding stub 140 to generate two mutually perpendicular electromagnetic components, thereby realizing the function of a circularly polarized antenna, which is suitable for satellite communication frequency bands.

[0044] If the switching device 130 is in the open state, the radiating stub 110 and the conductor 120 are disconnected. In this case, the radiating stub 110 can be used as an antenna design structure for non-satellite communication bands to support non-satellite communication band operation.

[0045] In one possible implementation, the antenna assembly also includes other radiating stubs (not shown), which are equipped with power supplies. When the switching device 130 is in the open state, power is supplied through the power supplies on the other stubs, enabling the antenna assembly to operate in non-satellite communication frequency bands.

[0046] In this embodiment, the antenna assembly includes parallel radiating stubs and conductors. A switching device and a feed stub are provided between the radiating stubs and conductors. The switching device connects the radiating stubs and conductors, so that the radiating stubs and conductors form a rectangular structure. Under the coupling feed of the feed stubs, two mutually perpendicular electromagnetic components are generated, which can realize circular polarization radiation and form a circular polarization antenna suitable for satellite communication frequency bands.

[0047] In some embodiments of this disclosure, such as Figure 4 As shown, the switching device 130 includes a first switch 131 and a second switch 132. The first switch 131 is disposed between the first end 111 of the radiating stub 110 and the first end 121 of the conductor 120, for connecting the first end 111 of the radiating stub 110 and the first end 121 of the conductor 120. The second switch 132 is disposed between the second end 112 of the radiating stub 111 and the second end 122 of the conductor 120, for connecting the second end 112 of the radiating stub 111 and the second end 122 of the conductor 120.

[0048] For example, the connection or disconnection of the radiating stub 110 with the conductor 120 is controlled by the first switch 131 and the second switch 132.

[0049] If both the first switch 131 and the second switch 132 are turned on, the radiating stub 110 and the conductor 120 are connected, forming a rectangular structure. In this case, the radiating stub 110 and the conductor 120 are coupled and fed through the feeding stub 130, generating two mutually perpendicular electromagnetic components to form a circularly polarized antenna that supports satellite communication frequency band operation.

[0050] If the first switch 131 and the second switch 132 are open, the radiating stub 110 and the conductor 120 are disconnected. In this case, the radiating stub 110 can be used as an antenna design structure for non-satellite communication bands, supporting operation in non-satellite communication bands.

[0051] In this embodiment, the first and second switches control the connection state between the radiating stub and the conductor in the antenna assembly. When both switches are on, the radiating stub and conductor form a rectangular structure, supporting circularly polarized antenna mode and improving communication performance. When both switches are off, the radiating stub can be used in non-satellite communication frequency bands, supporting non-satellite frequency band operating modes and enhancing adaptability. This design achieves multi-band support through simple switching operations, reducing design complexity and cost, and improving antenna integration.

[0052] It should be noted that the switching device can be designed in other forms besides being a first switch and a second switch. For example, the switching device can be designed as a relay, using electromagnetic force to close or open the connection between the radiating stub and the conductor. Alternatively, the switching device can be a varactor diode, adjusting the capacitance by changing the voltage across the varactor diode, thereby controlling the connection or disconnection between the radiating stub and the conductor. The embodiments of this disclosure can be designed with switching devices according to actual needs to control the connection or disconnection between the radiating stub and the conductor.

[0053] In some embodiments of this disclosure, such as Figure 5 As shown, the radiating branch 110 includes a first protrusion 113 and a second protrusion 114. The first protrusion 113 extends from the first end 111 of the radiating branch 110 toward the conductor 120, and the second protrusion 114 extends from the second end 112 of the radiating branch 110 toward the conductor 120. The conductor 120 includes a third protrusion 123 and a fourth protrusion 124. The third protrusion 123 extends from the first end 121 of the conductor 120 toward the radiating branch 110, and the fourth protrusion 124 extends from the second end 122 of the conductor 120 toward the radiating branch 110.

[0054] In some embodiments of this disclosure, a first switch 131 is disposed between a first protrusion 113 and a third protrusion 123 for connecting the first protrusion 113 and the third protrusion 123; a second switch 132 is disposed between a second protrusion 114 and a fourth protrusion 124 for connecting the second protrusion 114 and the fourth protrusion 124.

[0055] The first end 111 of the radiating branch 110 has a first protrusion 113 facing the conductor 120, and the first end 121 of the conductor 120 has a third protrusion 123 facing the radiating branch 110. A first switch 131 is provided between the first protrusion 113 and the third protrusion 123, and the first protrusion 113 and the third protrusion 123 are connected by the first switch 131 to connect the first end 111 of the radiating branch 110 to the first end 121 of the conductor 120.

[0056] The second end 112 of the radiating branch 110 has a second protrusion 114 facing the conductor 120, and the second end 122 of the conductor 120 has a fourth protrusion 124 facing the radiating branch 110. A second switch 132 is provided between the second protrusion 114 and the fourth protrusion 124, and the second protrusion 114 and the fourth protrusion 124 are connected by the second switch 132 to connect the second end 112 of the radiating branch 110 to the second end 122 of the conductor 120.

[0057] In this embodiment, the radiating stub and the conductor are each provided with protrusions, including first and second protrusions extending from the first and second ends of the radiating stub toward the conductor, and third and fourth protrusions extending from the first and second ends of the conductor toward the radiating stub. A first switch is disposed between the first and third protrusions, and a second switch is disposed between the second and fourth protrusions. This protrusion design increases the contact area at the connection point of the first and second switches, ensuring a stable electrical connection when both switches are on. Furthermore, the protrusions not only provide electrical connection but also enhance mechanical stability, making the connection between the radiating stub and the conductor more robust and reducing loosening due to vibration or impact.

[0058] In some embodiments of this disclosure, the dimension L1 of the radiating stub 110 along the first direction ranges from 38 mm to 44 mm. The dimension L2 of the conductor 120 along the second direction ranges from 0.7 mm to 1.7 mm. The dimension L3 of the feed stub 130 along the first direction ranges from 9 mm to 11 mm, and the dimension L4 of the feed stub 130 along the second direction ranges from 2.8 mm to 3.8 mm. The distance L5 between the conductor 120 and the radiating stub 110 ranges from 3.8 mm to 4.8 mm.

[0059] Considering the complex antenna environment of electronic equipment, the parameter design of radiating stub 110, conductor 120, and feed stub 130 was obtained through simulation and debugging. For example... Figure 3 As shown, the dimension L1 of the radiating stub 110 along the first direction ranges from 38 mm to 44 mm; the dimension L2 of the conductor 120 along the second direction ranges from 0.7 mm to 1.7 mm; the dimension L3 of the feed stub 130 along the first direction ranges from 9 mm to 11 mm; and the dimension L4 of the feed stub 130 along the second direction ranges from 2.8 mm to 3.8 mm. Furthermore, the distance L5 between the conductor 120 and the radiating stub 110 ranges from 3.8 mm to 4.8 mm.

[0060] In one possible implementation, the dimension L1 of the radiating stub 110 along the first direction is 41 mm, the dimension L2 of the conductor 120 along the second direction is 1.2 mm, the dimension L3 of the feed stub 130 along the first direction ranges from 10 mm, and the dimension L4 of the feed stub 130 along the second direction ranges from 3.3 mm. Furthermore, the distance L5 between the conductor 120 and the radiating stub 110 ranges from 4.3 mm.

[0061] In this embodiment of the disclosure, the parameters of the radiating stubs, conductors and feed stubs of the antenna assembly are determined by simulation debugging, which can optimize the performance of the antenna assembly and enable the antenna assembly to support full-band operation of satellite communication without relying on additional switches or adjustment devices to optimize the performance of the transmission and reception bands separately.

[0062] In some embodiments of this disclosure, the two ends of the radial branch are respectively provided with a slit, and the width of the slit along the first direction ranges from 0.8 mm to 1 mm.

[0063] For example, the first end 111 and the second end 112 of the radiating branch 110 are respectively provided with a slit, and the width of the slit along the first direction is in the range of 0.8mm to 1mm.

[0064] In this embodiment, slits are provided at both ends of the radiating stub. These slits can alter the current distribution and path of the radiating stub, thereby affecting the resonant frequency of the antenna assembly. Furthermore, the optimal slit width range can be obtained through simulation debugging and parameter optimization, achieving optimal performance of the antenna assembly.

[0065] An exemplary embodiment of this disclosure also provides an electronic device that may include a mid-frame, a border, and the antenna assembly described above, with radiating branches of the antenna assembly located on the border.

[0066] For example, the electronic device may be a mobile phone, tablet computer, e-reader, MP3 player, MP4 player, laptop computer, in-vehicle system or desktop computer, portable terminal, laptop terminal, desktop terminal, action camera, drone, monitor camera and similar products.

[0067] Figure 6 This is a plan view of an electronic device according to an exemplary embodiment of the present disclosure. Figure 6 This is a top view of the structure of the mid-frame, bezel, and antenna assembly in an electronic device, viewed from the front side, that is, from the side facing the electronic screen.

[0068] like Figure 6 As shown, the electronic device includes a frame 610, and a radiating stub 110 of the antenna assembly is disposed on the frame 610. The electronic device also includes a frame 620 and a frame 630, with a gap 611 between the frame 610 and the frame 620, and a gap 612 between the frame 610 and the frame 630.

[0069] For example, the frame of the electronic device is a metal frame, and the radial branch 110 is a metal frame segment formed by opening the metal frame of the electronic device through the opening of the slits 611 and 612.

[0070] likeFigure 6 As shown, the electronic device also includes a mid-frame 640, which supports structures such as the display screen. The mid-frame 640 serves as the primary reference ground for the electronic device. Reference ground refers to the conductive portion of the electronic device that is unaffected by any grounding configuration. The potential of the reference ground is conventionally zero. The mid-frame 640 can be made of metal, such as aluminum alloy or titanium alloy. Figure 6 The image also shows the position of the conductor 120 relative to the mid-frame 640. When viewed from the back side of the electronic device, that is, from the side of the electronic screen facing away from the electronic device, the conductor 120 is located above the mid-frame 640.

[0071] In one possible implementation, the middle frame 640 serves as the overall ground, and the ground plane on the electronic device is connected to the middle frame 640 to provide ground potential. In another possible implementation, a portion of the middle frame 640 serves as a ground plane, and grounding units, grounding points, etc., in the electronic device are connected to this portion of the middle frame 640 to be grounded.

[0072] In some embodiments of this disclosure, a gap 613 is provided between the middle frame 640 and the radial branch 110, and the width of the gap 613 along the second direction is 1.2 mm.

[0073] The radiating stub 110 has slits 611 and 612 at both ends, and a gap 613 between the radiating stub 110 and the middle frame 640, forming a ring-shaped electromagnetic structure between the radiating stub and the middle frame. This ring-shaped structure generates a LOOP mode under the influence of an electromagnetic field. By setting the parameters of the radiating stub 110, slits 611, slits 612, and gap 613, the LOOP mode generated by the ring-shaped structure operates behind the operating frequency band of the circularly polarized antenna (i.e., the satellite communication frequency band). Thus, when the antenna assembly radiates electromagnetic waves in its satellite communication frequency band, the electromagnetic radiation generated by the LOOP mode will not interfere with the electromagnetic waves in the main radiation direction (i.e., the electromagnetic waves generated by the radiating stub and the conductor), and can enhance the intensity of the electromagnetic waves in the main radiation direction through electromagnetic coupling, thereby improving the radiation efficiency of the antenna assembly.

[0074] In this embodiment, the radiating stubs of the antenna assembly, the gaps at both ends of the radiating stubs, and the gap between the radiating stubs and the middle frame form a ring-shaped electromagnetic structure between the radiating stubs and the middle frame. By controlling the length of the ring-shaped structure, the LOOP mode generated by this ring-shaped structure operates on the rear side of the operating frequency band of the circularly polarized antenna, thereby further improving the radiation efficiency of the antenna assembly.

[0075] In some embodiments of this disclosure, the electronic device also includes a circuit board.

[0076] Figure 7This is a plan view of an electronic device according to an exemplary embodiment of the present disclosure. Figure 7 This is a top view of the structure of the mid-frame, circuit board, and antenna assembly in an electronic device, viewed from the back side, that is, from the side away from the electronic screen.

[0077] like Figure 7 As shown, the electronic device also includes a circuit board 710. The circuit board 710 can be a PCB (Printed Circuit Board) that provides ground in the electronic device, which can be independently disposed outside the middle frame 640 of the electronic device, or disposed on the middle frame 640.

[0078] For example, the radiating stub 110 of the antenna assembly is connected to the circuit board 710 via a first connector.

[0079] In one possible implementation, the first connector includes a first spring and a second spring, wherein the spring is a component made of a flexible metal sheet or conductive material, designed to provide a reliable electrical connection within a limited space.

[0080] The first protrusion 113 of the radial branch 110 has a first spring tab at its end, and the second protrusion 114 of the radial branch 110 has a second spring tab at its end. The first protrusion 113 and the second protrusion 114 of the radial branch 110 are aligned with corresponding positions on the circuit board 710. After alignment, the first and second spring tabs on the radial branch 110 contact the contact points on the circuit board 710, connecting the radial branch 110 to the circuit board 710.

[0081] For example, the conductor 120 of the antenna assembly is mounted on the circuit board 710, and the conductor is connected to the circuit board 710 via a second connector.

[0082] In one possible implementation, a bracket is mounted on the circuit board 710, and the conductor 120 is mounted on the circuit board 710 via the bracket. The third protrusion 123 and the fourth protrusion 124 of the conductor 120 are aligned with corresponding areas of the circuit board 710, wherein the areas of the circuit board 710 that align with the third protrusion 123 and the fourth protrusion 124 are exposed copper. The second connector includes a first screw and a second screw. The first screw connects the third protrusion 123 of the conductor 120 to the circuit board 710, and the second screw connects the fourth protrusion 124 of the conductor 120 to the circuit board 710.

[0083] For example, the switching device 130 of the antenna assembly is disposed on the circuit board 710.

[0084] In one possible implementation, the switching device 130 may include a first switch 131 and a second switch 132. Both the first switch 131 and the second switch 132 are disposed on the circuit board 710. A first protrusion 113 of the radiating branch 110 is connected to the circuit board 710, and a third protrusion 123 of the conductor 120 is connected to the circuit board 710. The first switch 131 is disposed between the first protrusion 113 and the third protrusion 123 for connecting the first protrusion 113 and the third protrusion 123. A second protrusion 114 of the radiating branch 110 is connected to the circuit board 710, and a fourth protrusion 124 of the conductor 120 is connected to the circuit board 710. The second switch 132 is disposed between the second protrusion 114 and the fourth protrusion 124 for connecting the second protrusion 114 and the fourth protrusion 124.

[0085] For example, the feed stub 140 of the antenna assembly is connected to the circuit board 710 via a third connector. The third connector may be a third spring, which connects the feed stub 140 to the circuit board 710, and the feed stub 140 is located between the radiating stub 110 and the conductor 120.

[0086] In this embodiment of the disclosure, the circuit board, as a core component of the electronic device, provides the basis for electrical connections. Connecting the radiating branches, conductors, switching devices, and feed branches of the antenna assembly to the circuit board can ensure that the signals received and transmitted by the antenna assembly can be smoothly transmitted to other parts of the electronic device.

[0087] In some embodiments of this disclosure, the first distance of the conductor 120 relative to the circuit board 710 is the same as the second distance of the power supply stub 110 relative to the circuit board 710.

[0088] For example, the conductor 120 is mounted on the circuit board 710, and the power supply branch 140 is connected to the circuit board 710 through a third connector. The first distance (or height) of the conductor 120 relative to the circuit board 710 is the same as the second distance of the power supply branch 140 relative to the circuit board 710. That is, the conductor 120 and the power supply branch 140 are located on the same level, which can make the coupling degree of the power supply better.

[0089] In one possible implementation, the circuit board 710 can be set independently outside the middle frame 640 of the electronic device, or it can be set on the middle frame 640. The conductor 120 and the power supply branch 140 are at a certain distance (first distance) from the circuit board 710. The distance between the conductor 120 and the power supply branch 140 and the circuit board 710 can be set to 2.4mm according to the thickness of the frame of the electronic device.

[0090] In this embodiment, the electronic device includes a mid-frame, a frame, a circuit board, and the aforementioned antenna assembly. The antenna assembly includes a radiating stub, a conductor, a switching device, and a feed stub. Exemplarily, the radiating stub is disposed on the frame, the conductor is disposed parallel to the radiating stub, the switching device is disposed between the radiating stub and the conductor to connect them, forming a rectangular structure, and the feed stub is disposed between the radiating stub and the conductor, providing coupled feeding to generate two mutually perpendicular electromagnetic components, forming a circularly polarized antenna suitable for satellite communication operating frequencies.

[0091] Viewed from the back of the electronic device, that is, from the side away from the electronic screen, the order of the various parts of the electronic device from top to bottom (or from the position near the back of the electronic device, layer by layer to the screen) is as follows: At the top is the conductor mounted on the circuit board, and the power supply branch connecting the circuit board.

[0092] Figure 8 This is a simulation S11 diagram of an antenna assembly shown according to an exemplary embodiment of the present disclosure. The S11 value reflects the degree of matching between the antenna assembly and the transmission line, and a lower S11 value means a better match. Figure 8 In this configuration, the antenna assembly operates within the same frequency band as the satellite, ensuring effective communication between the antenna assembly and the satellite. Figure 8 It can be seen that, in addition to the main wave, there is a significant parasitic wave in the satellite operating frequency band of the antenna assembly, which can improve the efficiency of the satellite operating frequency band.

[0093] Figure 9 This is a simulation efficiency diagram of an antenna assembly illustrated according to an exemplary embodiment of the present disclosure. Figure 9 In the simulation, the antenna component achieved an efficiency of over -1 dB, indicating that the antenna component has very high radiation efficiency and can effectively convert the input radio frequency energy into electromagnetic waves radiated into space, which can significantly improve the circular polarization gain.

[0094] Figure 10 This is a simulated axial aspect ratio diagram of an antenna assembly illustrated according to an exemplary embodiment of this disclosure.
