Abstract
Description
Technical Field
[0001] This invention relates to the field of handheld communication devices, and more particularly to an antenna and a handheld communication device. Background Technology
[0002] Satellite communication is an effective means of communication in areas where cellular base station coverage is limited or the signal is poor. Integrating satellite communication technology into mobile phones presents several technical challenges. Currently, the electromagnetic waves used for wireless communication between handheld communication devices and cellular base stations or other devices typically propagate in a linearly polarized manner. However, for communication between ground devices and satellites hundreds or even thousands of kilometers away, the long propagation distance and the need to pass through the atmosphere cause polarization distortion in linearly polarized antennas due to the Faraday rotation effect of the ionosphere. Circularly polarized waves, on the other hand, are less affected by multipath effects and polarization distortion, do not have stringent requirements for the placement of the receiving antenna, and are resistant to cloud and rain interference. Therefore, to improve the reliability and stability of satellite communication and effectively reduce signal distortion and attenuation, circularly polarized antennas are a better choice. Mobile phones are small in size and contain many internal metal components, making the integration of circularly polarized or elliptically polarized antennas with a low axial ratio very difficult. This makes it an urgent problem to solve to achieve a circularly polarized antenna for stable and reliable satellite communication without affecting the portability of traditional handheld communication devices.
[0003] Currently, wireless charging technology for mobile phones has gradually become widespread and is a common charging method. The wireless charging coil is usually located in the center of the back of the phone, as this position makes it relatively easy to access the coil on the charger in most phones. Since the wireless charging coil module is located under the back cover, the satellite antenna above the back cover can interfere with normal charging, reducing charging efficiency. Existing technology does not consider the coexistence of the wireless charging coil and the satellite communication antenna, and fails to avoid the mutual interference between wireless charging and the satellite communication antenna. Summary of the Invention

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] Example 1
[0039] like Figure 1-8 As shown, this invention discloses an antenna for a handheld communication device, comprising:
[0040] The antenna body 1, including circularly polarized or elliptical polarized antenna elements, is disposed on the mobile terminal body 3 and is used to receive and transmit signals during satellite communication. In this embodiment, the target object is a satellite. When non-satellite communication is implemented, the target object can also be the ground.
[0041] The antenna unit is provided with an antenna radiation module 4 and a wireless charging coil module 5. The wireless charging coil module 5 is set on the antenna radiation module 4 to form an electromagnetic induction area to realize the wireless charging mode.
[0042] The position adjustment mechanism 2, connected to the antenna body 1, adjusts the usage posture of the antenna body 1 to a retracted state when wireless charging mode needs to be activated, thereby establishing a connection between the wireless charging coil module 5 and the mobile terminal body 3, enabling wireless charging functionality. During satellite communication, the usage posture of the antenna body 1 is adjusted to control it to reach the target communication location area in satellite communication mode, thus achieving satellite communication functionality. Integrating the wireless charging coil module onto the antenna unit allows for wireless charging in non-satellite communication mode, reducing interference from the satellite antenna to normal charging and improving charging efficiency.
[0043] Simultaneously, the position adjustment mechanism 2 enables the antenna body 1 to switch between an extended state and a retracted state, allowing the antenna body 1 to enter the corresponding satellite communication mode, non-satellite communication mode, and wireless charging mode. In this embodiment, the antenna body 1 can achieve satellite communication mode in the extended state, and can achieve terrestrial communication mode in any state, i.e., extended or retracted / folded.
[0044] The antenna radiation module 4 is connected to the mobile terminal body 3, and the radio frequency signal of the antenna radiation module 4 is connected to the mobile terminal body 3. The position adjustment mechanism 2 controls the position relationship of the antenna unit relative to the mobile terminal body 3, so as to realize the position switching of the antenna unit in satellite communication mode and non-satellite communication mode and enter the corresponding mode. It can be understood that when the antenna unit is unfolded, it can trigger satellite communication mode as needed, or it can be in non-satellite communication mode when unfolded. When the antenna unit is folded, it can trigger wireless charging mode as needed, or it can not activate wireless charging mode when folded. In this embodiment, the antenna unit can also realize terrestrial communication function when non-satellite communication is not needed.
[0045] In one embodiment, the mobile terminal body 3 is provided with a charging trigger unit 31, which is connected to the wireless charging coil module 5. The charging trigger unit 31 is used to trigger the wireless charging mode during charging, at which time the wireless charging coil module is disconnected from the mobile terminal device. In this embodiment, the mobile terminal body 3 can be a mobile phone or tablet computer, etc. When the antenna unit is in a retracted state, the charging trigger unit 31 is connected to the wireless charging coil module 5, and only the wireless charging function is available at this time. The wireless charging mode is only activated when needed, such as when the device is placed on the charging dock for charging.
[0046] Those skilled in the art will understand that the antenna body 1 consists of an antenna element and a position adjustment mechanism 2, such as Figure 1 The position adjustment mechanism 2 used in this embodiment can be a flipping mechanism, which includes a rocker arm 7 and a steering component 6. One end of the rocker arm 7 is connected to one end of the antenna unit, and the other end of the rocker arm 7 is connected to the mobile terminal body 3 via the steering component 6. In another embodiment, the flipping mechanism can also be one or more steering components 6, arranged along any edge of the first mounting portion 32, so that the antenna body 1 can rotate along the long or short side of the mobile phone. The difference from the above flipping mechanism is that the antenna unit and the steering component 6 are directly connected to the mobile terminal body 3 to achieve the flipping function. In non-satellite communication mode, the antenna body 1 and the flipping component are stored in the casing of the mobile terminal body 3. At this time, the wireless charging module is connected to the charging control module inside the mobile phone and can perform wireless charging. In satellite communication mode, the antenna body 1 is flipped out by the flipping component and unfolded to a suitable communication orientation. At this time, the wireless charging coil module 5 is flipped out along with the antenna body 1, disconnecting the contact connection and becoming inoperable.
[0047] In one embodiment, the radiation direction of the antenna body 1 is set opposite to the propagation direction of the satellite antenna beam to achieve maximum gain. The propagation direction of the satellite antenna beam includes the direct satellite propagation beam, the ground station beam, or an effective beam reflected or transmitted through a smart metasurface. A smart metasurface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic properties, developed from metamaterials technology. RIS typically consists of a large number of carefully designed electromagnetic units. By applying control signals to the adjustable elements on these units, the electromagnetic properties of these units can be dynamically controlled, thereby achieving active intelligent control of space electromagnetic waves in a programmable manner, forming an electromagnetic field with controllable parameters such as amplitude, phase, polarization, and frequency. Deploying RIS on the surfaces of various objects in a wireless transmission environment can alter the physical properties of the wireless channel. When the channel conditions are poor, RIS can improve the transmission of information between the transmitter and receiver by reflecting electromagnetic waves around obstacles. RIS can improve the overall capacity and performance of the system by improving the channel environment. To address the significant path loss between satellite and ground during satellite communication, an active RIS (Radio Reduction Signal) is introduced to enhance the ground signal, thereby ensuring effective communication between the mobile terminal and the satellite. The maximum gain direction of the antenna body is close to the propagation direction of the satellite antenna beam, which can be a direct satellite beam, a ground station beam, or an effective beam reflected or transmitted through a smart metasurface.
[0048] Considering the transmission loss of satellite-to-ground communication links, the frequency bands currently used in mobile terminals are mainly concentrated in low-frequency bands such as L or S. This is because the lower the frequency, the lower the free-space propagation loss, which reduces the requirements for antenna gain and power consumption in mobile communication terminals, making direct satellite phone connections possible. As more constellations are deployed towards low Earth orbit (LEO) and even very low Earth orbit (VLEO), the free-space propagation loss will be greatly reduced due to the reduced transmission distance. In the future, even higher Ku / Ka or Q / V frequency bands may be directly used in mobile communication terminals.
[0049] In satellite communication, optimal reception is achieved when the antenna's transmitting and receiving polarizations are matched. However, satellite-to-ground communication involves long distances and complex environments along the transmission path. In particular, the anisotropic characteristics of atmospheric molecules and rain / fog droplets in the troposphere can alter the polarization of electromagnetic waves, a phenomenon commonly known as depolarization. If linearly polarized antennas from traditional handheld communication devices are used, polarization distortion can cause polarization mismatch losses, potentially leading to communication failure. Circularly polarized antennas, less affected by multipath effects and polarization distortion, effectively reduce signal distortion and attenuation, significantly improving the reliability and stability of satellite communication, making them a superior choice.
[0050] In one embodiment, the circularly polarized or elliptical polarized antenna element is a radiator with symmetry or rotational symmetry to achieve equal horizontal and vertical amplitude components. The antenna element used in this embodiment is flat, such as an antenna element constructed from a PCB board, to achieve equal horizontal and vertical amplitude components with a phase difference of 90° or 270°. The antenna element used in this embodiment can also be rectangular, square, or other regular shapes.
[0051] In one embodiment, the antenna body 1 is composed of a circularly polarized or elliptically polarized antenna element with a low axis ratio, an RF transmission line 8, and other components. The flipping mechanism connects the antenna body 1 and the device housing at both ends via steering components 6. The flipping mechanism causes the antenna body 1 to rotate along the X and Y axes. The X-axis is a straight line parallel to certain geometric features of the device, such as the line parallel to the intersection of the plane and top surface of the phone's back cover. The Y-axis is a straight line perpendicular to the X-axis, such as... Figure 2 This can be understood as follows: rotating along the Y-axis means that the antenna body 1 flips up and down along the flipping direction, and rotating along the X-axis means that the antenna body 1 rotates around its entire body after flipping out to adjust to a suitable communication position.
[0052] In one embodiment, satellite communication between the antenna body 1 and the mobile terminal via the position adjustment mechanism 2 is achieved through an internally installed radio frequency transmission line 8 that passes through the flipping mechanism into the device, connecting the antenna unit and the motherboard of the mobile terminal body 3. Figure 3-5 Show.
[0053] The prevalence of low-frequency bands currently leads to larger antenna sizes. Mobile communication devices are typically rectangular prisms with very thin profiles. Achieving equal amplitude resonance in both the thickness and length (width) directions is difficult. Furthermore, the complex internal structure of mobile phones makes it extremely challenging to fully integrate a broadband circularly polarized antenna. Therefore, professional handheld satellite devices on the market often have large and conspicuous antennas, resulting in very bulky and heavy devices that do not conform to the slim and lightweight characteristics and development trends of modern smart mobile terminals.
[0054] To address the aforementioned shortcomings, the mobile terminal body 3 is provided with an inwardly recessed first mounting portion 32. This first mounting portion 32 houses the position adjustment mechanism 2 and the antenna unit. One end of the position adjustment mechanism 2 is connected to the antenna unit, and the other end of the position adjustment mechanism 2 is connected to the interior of the mobile terminal body 3 via the first mounting portion 32 to establish a connection between the mobile terminal body 3 and the antenna unit, thereby enabling the wireless charging function to operate. In this embodiment, the inwardly recessed first mounting portion 32 can be directly disposed on the back of the mobile terminal body 3 or a mounting layer can be added to the back of the mobile terminal body 3, with the inwardly recessed first mounting portion 32 disposed on the mounting layer.
[0055] The charging trigger part 31 is disposed on the first mounting part 32, and the contact part 33 is disposed at the bottom end of the antenna unit that can be accommodated in the first mounting part 32. In non-satellite communication mode, the antenna unit is housed in the first mounting part 32, so that the charging trigger part 31 and the contact part 33 are correspondingly connected, which enables the wireless charging function to be in a working state.
[0056] In order to achieve satellite communication without increasing the thickness of the mobile terminal body 3, the first mounting part 32 used in this embodiment is a specially designed concave structure for the handheld communication device casing, such as... Figure 4 As shown, when not in satellite communication mode, the antenna assembly is folded and stored in a concave structure within the device housing for safekeeping, such as... Figure 5 As shown, during satellite communication, the antenna body 1 is flipped out from the concave structure of the casing by the flipping mechanism and moved to a suitable communication position outside the mobile phone and stops.
[0057] In one embodiment, the wireless charging coil module 5 includes a wireless charging coil module 54 and a positioning magnetic ring 55, the positioning magnetic ring 55 being disposed close to and surrounding the wireless charging coil module 54. The positioning magnetic ring 55 helps to align the coil on the charger with the coil on the back of the phone, improving charging efficiency.
[0058] In another embodiment, the wireless charging coil module 5 includes a wireless charging coil module 54, a magnetic shielding sheet (not shown in the figure), and a positioning magnetic ring 55. The magnetic shielding sheet is disposed on the outer surface of the wireless charging coil module 54 near the signal interface of the mobile terminal body 3, and the positioning magnetic ring 55 is disposed close to and around the wireless charging coil module 54, which is beneficial to improving charging efficiency.
[0059] The antenna radiating module 4 includes radiating arms and a feed network (not shown in the figure). The radiating arms and the feed network are distributed on the upper surface, side surface, or bottom surface of the antenna element, avoiding the electromagnetic induction zone. Those skilled in the art will understand that the radiating arms and feed network of the antenna element are distributed in the top surface and lower metal layer of the antenna element, and one end of the radio frequency transmission line 8 is soldered to the antenna element feed network, such as... Figure 6-7 Show.
[0060] Plastic is wrapped around the antenna element and the solder joint of the RF transmission line 8 to form the frame 10 of the antenna body 1. The top and bottom surfaces of the antenna element are components of the top and bottom surfaces of the antenna body 1, such as... Figure 7 Show.
[0061] Consider the scenario where a wireless charging coil and a satellite communication antenna coexist. The antenna unit has a contactable portion 33, which is the contactable area formed by the lead end of the charging coil inside the wireless charging coil module 5 extending to the outer surface of the antenna unit. The charging trigger portion 31 is positioned opposite to the contactable portion 33, and the connection between the charging trigger portion 31 and the contactable portion 33 enables the wireless charging function to operate. Those skilled in the art will understand that the wireless charging control module is inside the mobile phone, and its two lead contact pads are on a flipping mechanism, allowing contact with the aforementioned pogopin elastic connector, thus achieving communication between the charging coil and the internal charging control module of the mobile phone. Figure 8 Show.
[0062] In one embodiment, such as Figure 8 As shown, the contact portion 33 is a flexible connector. The flexible connector used in this embodiment can be a pogo pin, which has a large compression capacity, reducing the pressure of the spring and providing automatic adsorption, zero insertion force, and automatic orientation functions. It can provide a reliable connection for hard-to-reach locations. Two leads of the charging coil inside the antenna unit are led to the outside of the antenna unit. The wireless charging control module is inside the mobile terminal body 3. The two leads connect the charging coil and the control module via the flexible connector.
[0063] In one embodiment, to meet the aesthetic and user comfort requirements of the mobile terminal body 3, the overall thickness of the mobile terminal body 3 needs to be adapted to minimize its impact on appearance and portability. To reduce the thickness of the mobile terminal body 3, the charging trigger part 31 is a contact pad structure, which can also be disposed on the outer surface of the mobile terminal or on the first mounting part 32. The contact pad structure has a plurality of contacts distributed on it; the advantage of contact connection is that it can improve durability and signal transmission reliability. In this embodiment, gold, copper, zinc, palladium, nickel, silver, or alloys are used as materials for the connector contact electroplating.
[0064] In one embodiment, the wireless charging coil module 5 is connected to the charging trigger part 31 in a contact manner, so that the wireless charging function is in a working state, making the thickness of the mobile terminal body 3 thinner and lighter.
[0065] In another embodiment, the wireless charging coil module 5 and the charging trigger unit 31 are connected in a non-contact manner to enable the wireless charging function to work, that is, the wires on the surface of the wireless charging coil module 5 are directly connected to the main body of the mobile terminal.
[0066] In various embodiments of this application, see [link to relevant documentation]. Figure 1-3As shown in Figures 5 and 7, the antenna unit is provided with a second mounting portion 51 for accommodating the wireless charging coil module 5. The second mounting portion 51 forms a sensing area 52 and a non-sensing area 53 on the antenna unit. The sensing area 52 is the upper surface of the wireless charging coil module 5 that is away from and directly opposite the internal wireless charging coil. The non-sensing area 53 is the upper surface of the antenna unit excluding the sensing area 52. Those skilled in the art will understand, see [reference needed]. Figure 6 As shown, the circularly polarized or elliptically polarized antenna unit with a low axis ratio has a flat shape and a groove in the middle, which is the second mounting part 51 described in this embodiment. The wireless charging coil module 54 and the positioning magnetic ring 55 are at the bottom of the groove. The heat sink 9 of the wireless charging coil module 54 is at the bottom of the antenna unit. The two leads of the charging coil are led to the outside of the antenna unit through two pogo pins. In this embodiment, the second mounting part 51 that accommodates the wireless charging coil module 5 can also be other shapes besides being recessed inward.
[0067] In various embodiments of this application, the flipping mechanism used in this embodiment is connected to the antenna body 1 and the device housing at both ends by a steering component 6, respectively. The steering component 6 rotates steplessly, which facilitates the rotation and adjustment of the antenna unit to the target communication position. The flipping mechanism used in this embodiment can be a rocker arm structure or other structures.
[0068] In one embodiment, the position adjustment mechanism 2 includes a flipping mechanism, with steering components 6 at both ends of the flipping mechanism. Alternatively, one or more steering components 6 may be provided on one side of the flipping mechanism.
[0069] In one embodiment, the steering component 6 includes a first rotating component 61 and a second rotating component 62. The mobile terminal body 3 is connected to one end of the flipping mechanism via the first rotating component 61, thereby enabling the antenna body 1 to rotate relative to the mobile terminal body 3 about the rotation axis centerline of the first rotating component 61, thus realizing the flipping function of the antenna body 1. The rotation axis centerline of the first rotating component 61 is a rotation axis set along the width direction of the flipping mechanism, i.e., the X-axis reference line, see [reference]. Figure 1 As shown.
[0070] The antenna body 1 is connected to the other end of the flipping mechanism via the second rotating component 62, thereby enabling the antenna body 1 to rotate infinitely relative to the flipping mechanism about the center line of the rotation axis of the second rotating component 62, thus achieving circumferential rotation of the antenna body 1 after flipping. The center line of the rotation axis of the second rotating component 62 is a rotation axis set along the length direction of the flipping mechanism, i.e., a reference line in the Y-axis direction.
[0071] Those skilled in the art will understand that, Figure 1-2As shown, the flipping mechanism used in this embodiment has a first rotating component 61 and a second rotating component 62 at both ends, which are used to connect the antenna body 1 and the mobile terminal body 3. The second rotating component 62 is connected to the antenna body 1, and the first rotating component 61 is connected to the mobile terminal body 3. The flipping mechanism causes the antenna body 1 to rotate along the X and Y axes. In this example, the X axis is the center line of the rotation axis of the first rotating component 61, and the Y axis is the center line of the rotation axis of the second rotating component 62. When the antenna body 1 unfolds with the flipping mechanism, the antenna body 1 and the flipping mechanism move around the X or Y axis. This allows the user of the mobile terminal body 3 to communicate in a better way by adjusting the relative posture of the antenna body 1 and the mobile terminal body 3, regardless of the user's hand posture. This ensures that the antenna body 1's maximum gain direction is close to the propagation direction of the satellite antenna beam and maintains a suitable distance from the terminal device 3.
[0072] When not communicating with satellite, the antenna body 1 is folded and stored in the concave structure of the mobile terminal body 3. Before satellite communication, the antenna body 1 is flipped out of the concave structure of the housing by the flipping mechanism. The antenna is then searched for a suitable position for communication with satellite when holding the phone vertically within an angle of 0 to 270°. For communication with satellite when holding the phone horizontally, in addition to rotating out of the phone around the X-axis by the flipping mechanism, the antenna body 1 also needs to rotate steplessly around the Y-axis from 0 to 90° to find a better communication position.
[0073] In various embodiments of this application, the flipping mechanism has a continuous cavity inside, and the radio frequency transmission line 8 passes through the cavity to enter the inside of the mobile phone. The radio frequency transmission line 8 is composed of radio frequency coaxial line, circuit board containing microstrip line or coplanar waveguide, radio frequency connector, etc., either individually or in combination.
[0074] In various embodiments of this application, a heat sink 9 is provided at the bottom of the antenna unit.
[0075] Example 2
[0076] Based on the same concept as this invention, this invention also provides a handheld communication device, including the antenna described in Embodiment 1, specifically comprising:
[0077] The antenna body 1, including a circularly polarized or elliptically polarized antenna element, is mounted on the mobile terminal body 3 and is used to receive and transmit signals when communicating with a target object;
[0078] The antenna unit is provided with an antenna radiation module 4 and a wireless charging coil module 5. The wireless charging coil module 5 is set on the antenna radiation module 4 to form an electromagnetic induction area to realize the wireless charging mode.
[0079] The position adjustment mechanism 2, connected to the antenna body 1, adjusts the usage posture of the antenna body 1 to a retracted state when wireless charging mode needs to be activated, thereby establishing a connection between the wireless charging coil module 5 and the mobile terminal body 3, enabling wireless charging functionality. During satellite communication, the usage posture of the antenna body 1 is adjusted to control it to reach the target communication location area in satellite communication mode, thus achieving satellite communication functionality. Integrating the wireless charging coil module onto the antenna unit allows for wireless charging in non-satellite communication mode, reducing interference from the satellite antenna to normal charging and improving charging efficiency.
[0080] Meanwhile, the position adjustment mechanism 2 enables the antenna body 1 to switch between the extended state and the retracted state, allowing the antenna body 1 to enter the corresponding satellite communication mode, non-satellite communication mode, and wireless charging mode.
[0081] The antenna radiation module 4 is connected to the mobile terminal body 3, the radio frequency signal of the antenna radiation module 4 is connected to the mobile terminal body 3, and the position relationship of the antenna unit relative to the mobile terminal body 3 is controlled by the position adjustment mechanism 2.
[0082] The mobile terminal body 3 is equipped with a charging trigger unit 31, which is connected to the wireless charging coil module 5. This unit triggers the wireless charging mode during charging, at which point the wireless charging coil module is disconnected from the mobile device. In this embodiment, the mobile terminal body 3 can be a mobile phone or tablet computer, etc. When the antenna unit is in a retracted state, the charging trigger unit 31 is connected to the wireless charging coil module 5, and only the wireless charging function is available. The wireless charging mode is only activated when the device is placed on the charging dock for charging.
