[0041] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0042] Most PIFA antennas in electronic devices are linearly polarized antennas. This leads to significant polarization loss when receiving circularly polarized signals, such as GPS signals, affecting performance and preventing the provision of accurate and reliable location information. To improve antenna performance, circularly polarized antennas are formed by integrating the radiator with the existing structure of the electronic device.

[0043] like Figure 1 As shown, an electronic device includes a metal housing 10 and a radiator 20. The metal housing 10 includes a window area 11, and the radiator 20 is placed in the window area 11 for communication between the electronic device and the outside. The radiator 20 is provided with a cutout portion 21, which is used to avoid a target device 22.

[0044] It can be understood that the electronic device can include but is not limited to a smart phone, a tablet computer, a wearable device such as a smart watch, a fitness tracker, a drone, etc., all of which can provide better wireless communication performance by optimizing the structure of the antenna while ensuring a compact product appearance, especially improving the reception efficiency of circularly polarized signals such as GPS signals.

[0045] The metal shell 10 is the outer shell of the electronic device described above, which can improve the appearance and structural strength of the device. Since the metal shell 10 can shield wireless signals, in order to make the wireless signals pass smoothly without being blocked by the metal, a non-conductive windowed area 11 can be provided on the metal shell 10. The windowed area 11 can be a hollow area provided on the shell, which allows the inside and outside of the device to communicate; it can also be a window structure formed of plastic, glass or other non-conductive materials to enable the radiator 20 to effectively emit or receive signals.

[0046] The radiator 20 is a part for receiving electromagnetic waves. The core of the radiator 20 can be a metal material such as copper, aluminum, silver, etc. In order to save space, it is provided in the form of a thin sheet and installed in the electronic device, which can not only increase the effective receiving area of the signal, but also make the electronic device as a whole lighter and thinner.

[0047] The radiator 20 is provided in the windowed area 11 so that the radiator 20 is not affected by the shielding of the metal shell 10, which can help improve antenna efficiency and reduce loss. The radiator 20 is provided with a hollow part 21. The structure of the hollow part 21 can be a hole or a gap. Its purpose is to avoid the target device 22, which can be a camera, a sensor or other components that need to be exposed to the outside. The target device 22 is provided in the hollow part 21, which not only allows the radiator 20 and the target device 22 to coexist in physical space without interfering with each other, but also accommodates the target device 22 through the hollow part 21, which can keep the radiator away from these metal parts that may cause interference, thereby helping to maintain the optimal performance of the antenna.

[0048] In a compact device, the spatial layout of various components can be effectively managed. Placing the target device such as a camera in the hollow part of the antenna radiator can reasonably arrange multiple target devices 22 in limited space, thereby saving and optimizing the internal space of the electronic device.

[0049] On the other hand, the hollowing-out can also be used to flexibly adjust the shape and size of the radiator 20, thereby changing its electrical properties, such as the resonant frequency, bandwidth, and polarization mode, etc. For circularly polarized signal reception, by arranging the radiator 20 in the windowed area 11 of the metal shell 10 and setting the hollowing-out part 21 on the radiator to avoid the target device (such as a camera), the signal loss caused by the metal shielding can be reduced, the antenna efficiency and the ability to receive circularly polarized signals can be improved, thereby reducing the polarization loss, while optimizing the internal space layout of the device and improving the overall performance and user experience.

[0050] In some embodiments, as shown in FIG. 1, the electronic device further comprises a carrier 30 and a feeding part 31. The carrier 30 is used to carry and conduct electronic components, and is arranged in the shell and extends to the windowed area 11. The feeding part 31 is formed on the carrier 30 and is used to be coupled with the radiator 20. Figure 2

[0051] It can be understood that the carrier 30 is used to carry and conduct electronic components. The carrier 30 can serve as a physical support structure for mounting and fixing various electronic components, such as integrated circuits, resistors, capacitors, etc., and also needs to provide an electrical connection path to enable current and signal transmission between the above-mentioned components.

[0052] In some embodiments, as shown in FIG. 1, the carrier 30 can be a printed circuit board (PCB), and can also be a flexible circuit board (FPC), etc.

[0053] The feeding part 31 is a key interface for transferring radio frequency energy to the radiator 20. It is used to transfer the signal received by the radiator 20 from the transmitter to the receiver end of the electronic device.

[0054] The type of the feeding part 31 can be direct feeding, microstrip line feeding, etc. In particular, the microstrip line feeding is a kind of planar transmission line, which is commonly used in microstrip antennas. The microstrip line can be set on the PCB board by printing. It can also be probe feeding, which penetrates the dielectric layer through a short metal probe to the surface of the radiator 20. This feeding method is commonly used in patch antennas. By introducing the carrier 30 and the feeding part 31, the carrier 30 carries and conducts electronic components and extends to the windowed area 11, while the feeding part 31 is coupled with the radiator 20. This structure not only enhances the stability and efficiency of the antenna system, but also ensures good signal conduction and energy transmission, while simplifying the internal structure layout, improving the assembly convenience and reliability.

[0055] In some embodiments, as shown in FIG. 1, the electronic device further comprises a frame 40. The frame 40 is arranged in the metal shell 10 and on the side of the carrier 30 facing the windowed area 11, and is used to assemble the target device 22. The radiator 20 is arranged on the surface of the frame 40 facing the windowed area 11. Figures 2-3

[0056] ​​It can be understood that the frame 40 is used to provide mechanical support and protection, wherein the frame 40 is a non-metal material. The frame 40 can be a fixed frame or a fixed platform for mounting and fixing various target devices 22 such as camera modules, sensors, etc., to ensure the position stability of the above-mentioned devices and avoid function failure caused by movement or vibration of the electronic device. And the frame 40 also plays a role in separating the radiator 20 from the target device 22, which can reduce mutual interference between the two.

[0057] The frame 40 can be a limiting mounting rack inside the electronic device for assembling a limiting mainboard, a screen assembly, etc., or can also be arranged only in the windowed area 11 to assemble a mounting rack for the camera.

[0058] The frame 40 can help to reasonably distribute the internal space, so that the different components maintain an appropriate distance, thereby improving the compactness of the electronic device and the communication efficiency of the antenna.

[0059] The radiator 20 is arranged on the surface of the frame 40 to ensure that the radiator 20 can be maximally exposed to the windowed area 11 and can transmit and receive signals without obstruction. By arranging the frame 40 in the metal shell 10 and placing it on the side of the carrier 30 facing the windowed area 11 for assembling the target device 22, and arranging the radiator 20 on the surface of the frame 40 facing the windowed area 11, the above structure optimizes the internal space utilization of the electronic device, and enhances the structural stability and integrity.

[0060] For example, the electronic device is a smart phone, the phone adopts a full-metal back cover, and a non-metal windowed area 11 is provided at the top edge for antenna work. At this time: the frame 40 can be made of light but strong material (such as plastic or composite material) and extends from the metal shell 10 to below the windowed area 11 to form a stable frame. The carrier 30 (such as FPC) passes through the frame 40 and is connected with the main PCB to provide an electrical path for the antenna and other components. The radiator 20 as part of the frame 40 can be directly printed on the surface thereof or fixed by bonding, etc., to ensure that it is perfectly aligned with the windowed area 11. The target device 22 (such as a camera) is safely mounted in the frame 40 away from the antenna area, reducing potential interference sources.

[0061] In some embodiments, as shown in Figure 3 The metal layer 50 is arranged on the side of the feed part 31 away from the windowed area 11, and the metal layer 50 is used in combination with the feed part 31 to form a resonant loop to generate electromagnetic waves.

[0062] Understandably, the metal layer 50 is located on the side of the feed section 31 away from the window region 11, forming a closed oscillating circuit together with the feed section 31 through physical contact or a very close distance (e.g., separated by a medium). This circuit can support current oscillation at a specific frequency, thereby effectively generating and emitting electromagnetic waves.

[0063] The metal layer 50 can help extend the effective bandwidth of the antenna, enabling it to operate over a wider frequency range. As a reflective surface or ground plane, the metal layer 50 can enhance the forward radiation mode of the antenna, thereby increasing its gain.

[0064] To maximize current flow efficiency and reduce losses, the metal layer 50 is typically made of a material with high conductivity, such as copper or aluminum. This not only effectively conducts radio frequency current but also maintains good mechanical stability. The thickness of the metal layer 50 needs to be precisely controlled according to specific application requirements, ensuring sufficient conductivity while avoiding excessive thickness that would increase weight or occupy too much space.

[0065] The metal layer 50 does not directly contact the power supply part 31, but is separated by a dielectric material to form a capacitive coupling; wherein, the metal layer 50 can be a copper foil layer printed on the circuit board, or the metal light shield 60 on the back of the display screen can be used as the metal layer 50.

[0066] The oscillation circuit consists of a feed section 31 and a metal layer 50. When the radio frequency current passes through the feed section 31, a corresponding induced current is generated on the metal layer 50. The two work together to form a highly efficient electromagnetic wave emission source.

[0067] The metal layer 50 may also contain additional inductor or capacitor elements for fine-tuning the antenna’s operating frequency to ensure optimal performance within the target frequency band.

[0068] By providing a metal layer 50 on the side of the feed section 31 away from the window region 11 and combining it with the feed section 31 to form an oscillating circuit to generate electromagnetic waves, the transmission and reception performance of the antenna system is enhanced, the generation efficiency and stability of electromagnetic waves are improved, the antenna structure is simplified, external interference is reduced, and signal quality and communication reliability are improved.

[0069] In some embodiments, such as Figure 3 As shown, the metal layer 50 can be formed on the carrier 30; the carrier 30 includes a first surface and a second surface disposed opposite to each other, the first surface facing the window area 11, the power supply part 31 is formed on the first surface; the metal layer 50 is disposed on the second surface.

[0070] Understandably, the carrier 30 can be a flexible printed circuit board (FPC) or a rigid printed circuit board (PCB) at this time.

[0071] The first surface, serving as the main working surface of the carrier 30, supports the power supply unit 31 and other necessary electronic components. The power supply unit 31 is in direct coupling contact with the radiator 20, ensuring effective signal transmission.

[0072] The second surface is used to mount the metal layer 50, which can be used as a grounding layer or a reflector to help shape the electromagnetic wave reception pattern.

[0073] By distributing components with different functions to two opposite surfaces of the carrier 30, the internal space can be fully utilized without increasing the thickness, which helps to make the electronic device structure thinner and lighter.

[0074] PCB manufacturing technology allows for easy implementation of double-sided wiring and metal layer 50 deposition. The direct formation between the metal layer 50 and the carrier 30 ensures good electrical connection and mechanical stability between them, reducing problems caused by vibration or other stresses. Furthermore, the metal layer 50 also provides some heat dissipation, helping to maintain the operating temperature of electronic components within a safe range, extending their lifespan and maintaining stable performance.

[0075] For example, the carrier 30 may be made of a flexible circuit board (FPC) or a rigid PCB, passing through the inside of the phone and extending below the window area 11 at the top edge.

[0076] The power supply section 31 is printed on the first surface and is in coupling contact with the radiator 20 to ensure effective signal transmission.

[0077] The metal layer 50 is also formed on this surface by printing or etching processes, serving as a ground layer or reflector to help optimize antenna performance. To further optimize the layout, a frame 40 can be provided around the carrier 30 to fix the target device 22, such as a camera, while also providing additional support for the metal layer 50.

[0078] By providing a metal layer 50 on the side of the feed section 31 away from the window region 11 and combining it with the feed section 31 to form an oscillating circuit to generate electromagnetic waves, this structure enhances the antenna's transmission and reception performance and improves the generation efficiency and stability of electromagnetic waves.

[0079] In some embodiments, such as Figure 2 , Figure 4 As shown, it also includes a light-shielding plate 60, which is disposed on the side of the carrier 30 away from the window area 11, and a metal layer 50 is disposed on the light-shielding plate 60.

[0080] Understandably, the light shield 60 can be a metal plate on the back of the display screen, serving as the metal layer 50. This structure not only achieves optical isolation but also makes full use of the existing structure to enhance the performance of the antenna system, while simplifying the internal spatial layout of the device.

[0081] As a metal plate behind the display screen, the main function of the light shielding plate 60 is to prevent external light from penetrating the screen and reflecting onto the internal components, especially the camera module and other light-sensitive sensors. This helps to avoid image quality degradation or sensor malfunction caused by direct sunlight.

[0082] By forming the metal layer 50 on the light shielding plate 60 and combining it with the feed part 31, a closed oscillation loop is formed, supporting current oscillation at a specific frequency, thereby effectively generating and emitting electromagnetic waves. At this time, the feed part 31 can be formed on the first surface or the second surface of the carrier 30.

[0083] Forming the metal layer 50 on the light shielding plate 60 also makes full use of the internal space without increasing the additional thickness, which is particularly important for mobile devices pursuing lightweight design and reduces the number of separate components, simplifies the assembly process, and reduces production costs.

[0084] In some embodiments, as shown in Figure 3 The carrier 30 includes a first surface and a second surface arranged opposite to each other, the first surface faces the windowed area 11, and the second surface faces away from the windowed area 11.

[0085] The first surface is provided with an insulating area 32 at a position corresponding to the windowed area 11, and the radiator 20 is arranged on the insulating area 32, and the second surface is provided with a feed part 31.

[0086] It can be understood that the carrier 30 can be a printed circuit board (PCB), the first surface of the carrier 30 is used to carry the radiator 20, and the insulating area 32 is arranged at a position corresponding to the windowed area 11 on the first surface, and the radiator 20 is arranged on the insulating area 32, which can reduce electromagnetic interference and improve the receiving and transmitting performance of the antenna; the insulating area 32 not only can be part of the antenna, but also can act as a shielding layer to reduce electromagnetic interference between internal electronic components, and the presence of the insulating area 32 allows the radiator 20 to be arranged adjacent to the windowed area 11 without increasing the additional thickness, making full use of limited space resources, which helps to make the electronic device structure lightweight. The feed part 31 is formed on the second surface by printing and coupled to the radiator 20, forming a closed oscillation loop that supports current oscillation at a specific frequency, thereby effectively generating and emitting electromagnetic waves.

[0087] In some embodiments, as shown in Figure 4 The light shielding plate 60 is arranged on the side of the carrier 30 away from the target area and is spaced apart from the second surface, and the light shielding plate 60 is a metal plate.

[0088] It can be understood that, in the case where the radiator 20 is directly arranged on the first surface of the carrier 30, the metal layer 50 is formed on the light shield plate 60;

[0089] The light shield plate 60 is a metal plate at the back of the display screen, and the main function of the light shield plate 60 is to prevent external light from penetrating the screen and being reflected onto internal components, especially the camera module and other light-sensitive sensors. By forming the metal layer 50 on the light shield plate 60 and combining it with the feeding part 31, a closed oscillation loop is formed, supporting current oscillation at a specific frequency, thereby effectively generating and emitting electromagnetic waves.

[0090] In some embodiments, as shown in Figure 5 The feeding part 31 and the radiator 20 are arranged in a stacked and spaced manner, and the projection parts of the feeding part 31 and the radiator 20 in the direction perpendicular to the stacking direction overlap.

[0091] It can be understood that the feeding part 31 and the radiator 20 are arranged in a stacked manner, and a certain physical spacing is maintained between them to avoid short circuits or other electrical problems that may be caused by direct contact. This spacing can be achieved through a dielectric material such as plastic, ceramic, etc. The projection overlap allows efficient coupling between the feeding part 31 and the radiator 20 while reducing unnecessary space occupation. Since the feeding part 31 and the radiator 20 have a certain distance in the stacking direction, the coupling between them mainly depends on the action of the electromagnetic field. By adjusting the relative position and shape of the two, the coupling efficiency can be optimized to ensure effective transmission of radio frequency energy. The feeding part 31 can enhance the forward radiation pattern of the radiator 20, thereby improving the overall gain of the antenna. For applications that require specific polarization characteristics (such as GPS signal reception), the stacked design can assist in achieving the required polarization form by adjusting the relative angle between the feeding part 31 and the radiator 20, for example, right-handed circular polarization.

[0092] In some embodiments, as shown in Figure 1 The target device 22 is a camera.

[0093] It can be understood that, for example, the electronic device is a smart phone or tablet computer with camera function, including a metal shell 10, a PCB mainboard, and a display screen;

[0094] The window area 11 is arranged on the metal shell 10, and the frame body 40 is arranged at the position corresponding to the window area 11 inside the shell, which is used to assemble the camera. At this time, the radiator 20 can be arranged on the surface of the frame body 40 facing the window area, and the camera is placed in the hollow part 21 of the radiator 20. The frame body 40 is a non-conductor material, which is used as a dielectric substrate to carry the radiator 20. The PCB mainboard is arranged as the carrier 30 on the side of the frame body 40 away from the window area 11. The feeding part 31 is formed on the insulating area 32 of the surface of the PCB mainboard. The display screen is arranged on the side of the PCB mainboard away from the window area 11. At this time, the light shield plate 60 of the display screen is a metal plate, which is used as the metal layer 50 and combined with the feeding part 31 to form a closed oscillation loop, which supports the current oscillation at a specific frequency, so as to effectively generate and emit electromagnetic waves. Through the cooperation of the above components, the circularly polarized signal can be received, so as to effectively enhance the performance of the antenna. Thus, the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described.
