[0040] Figure 9 This is a three-dimensional structural diagram of a terminal according to an exemplary embodiment. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments 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 scope of the claims.

[0042] With the rapid pace of upgrades in terminal devices and the widespread adoption of 5G, there is a strong demand for both thinner and lighter terminal devices and wider 5G coverage. As terminal device screens become larger and thinner, the space available for antenna placement on these devices decreases.

[0043] The deteriorating antenna environment and the increasing number of antennas present a significant challenge to the manufacturing and development of terminal devices. The design of some terminal devices' internal support structures leaves no space for mounting antennas.

[0044] The increasing size and thinness of terminal devices, coupled with the growing number of antennas required for 5G, have all contributed to the increased difficulty in manufacturing these devices.

[0045] To overcome the problems existing in related technologies, this disclosure provides a terminal.

[0046] The terminal provided in this disclosure includes: a metal frame, including a first metal frame, the space adjacent to a first side of the first metal frame being the antenna clearance of the terminal; a first antenna, the first metal frame being configured as the antenna radiator of the first antenna; and a second antenna, disposed in the antenna clearance, wherein the antenna frequency of the first antenna is different from the antenna frequency of the second antenna.

[0047] This disclosure utilizes the antenna clearance area of ​​a first antenna configured as a frame antenna, and also sets up a second antenna within the antenna clearance area. This enables multiplexing of the internal spatial structure of the terminal, allowing the terminal's antenna to cover more frequency bands and improving the terminal's antenna coverage range. Furthermore, the antenna frequency of the second antenna in this disclosure is different from that of the first antenna, which ensures sufficient isolation between the first and second antennas, preventing interference between them and thus improving the terminal's antenna performance.

[0048] In this disclosure, the first metal frame can be any side or any part of the metal frame, as long as it meets the setting requirements of the first antenna and the second antenna. This disclosure does not impose specific limitations, thus allowing for greater flexibility in the setting of terminal antennas and making it applicable to various antenna layout requirements of various terminals.

[0049] For example, the entire metal part can be used as the antenna radiator, or only a portion of the metal part can be used. The specific approach depends on the antenna layout of the terminal device. For instance, in some cases, the required radiator area is large, so the entire metal part can be used. Alternatively, in other cases, the shape of the metal part can be modified to suit different antennas.

[0050] Based on the same concept, this disclosure also provides an antenna assembly, including: a first antenna including an antenna radiator made of a metallic material, the first antenna including ground; an antenna clearance located between the antenna radiator and the ground of the first antenna; a second antenna including a first dielectric disposed on a first side of the antenna radiator facing the antenna clearance, the antenna frequency of the first antenna being different from the antenna frequency of the second antenna; and a second dielectric, wherein the dielectric constant of the first dielectric is greater than the dielectric constant of the second dielectric.

[0051] This disclosure utilizes the antenna clearance of the first antenna, and simultaneously installs a second antenna within the antenna clearance. This allows for the reuse of the internal spatial structure of the antenna assembly, enabling the antenna assembly to cover more frequency bands and improve its coverage range. Furthermore, the antenna frequency of the second antenna in this disclosure is different from that of the first antenna. This ensures sufficient isolation between the first and second antennas, preventing interference between them and thus improving the antenna performance of the antenna assembly.

[0052] In some embodiments, the antenna assembly of this disclosure can be applied to a terminal. In this case, the metal material constituting the antenna radiator of the first antenna can be a metal component on the terminal, such as a metal frame, specifically the first metal frame as described above. When the first metal frame is used as the antenna radiator of the first antenna, the middle frame can be the ground plane of the first antenna.

[0053] The terminals mentioned in this disclosure may be electronic devices such as mobile phones, computers, tablets, personal digital assistants, and wearable devices.

[0054] Taking mobile phones as an example, mobile communication has developed rapidly over the past thirty years, undergoing generation after generation of technological innovations. As the gateway to the Internet, mobile phones are also undergoing significant changes. From the first-generation mobile phones, to the second-generation digital phones, to the third-generation multimedia phones, to the fourth-generation multi-functional smartphones, and finally to the 5G high-speed multi-functional phones, mobile phone antennas have gradually developed towards miniaturization, multi-frequency operation, and all-metal frames.

[0055] Currently, China has 2G, 3G, and LTE (4G) systems. 2G uses the 1710-1850MHz band, 3G uses the 1880-2170MHz band, and LTE (4G) uses the 2300-2690MHz band. China's wireless communication systems currently cover the 1710-2690MHz band. Meanwhile, the world has issued notices regarding the use of the 3300MHz-3800MHz and 4400MHz-5000MHz bands for fifth-generation mobile communication systems, signifying the imminent arrival of the 5G era. Mobile phones, as the representative of mobile communication, will inevitably lead the trend of the 5G era. Fifth-generation mobile communication technology (5G) will be commercially available on a large scale in 2020, and in the coming years, new mobile terminal antennas and base station antennas will have a broad application market.

[0056] 5G is divided into low-frequency bands below 6GHz (Sub-6GHz) and high-frequency bands above 24GHz (often referred to as 5G millimeter waves). Compared to the current 4G, 5G has many advantages, such as higher transmission speeds, lower latency, and higher reliability.

[0057] 3GPP has announced three frequency bands for 5G Sub-6GHz: N77 3.3–4.2GHz, N78 3.3–3.8GHz, and N79 4.4–5.0GHz. Countries can choose the specific frequency band they wish to use from these three bands based on their specific circumstances. On November 9, 2017, my country's Ministry of Industry and Information Technology announced the following three frequency bands as the operating frequency bands for my country's 5G system: 3.3GHz–3.4GHz, 3.4–3.6GHz, and 4.8GHz–5GHz.

[0058] The specific components of the first antenna and the second antenna are described in detail below. The first antenna and the second antenna described below can be either the first antenna and the second antenna of the antenna assembly, or the first antenna and the second antenna of the terminal.

[0059] Figure 1 This is a plan view of a terminal according to an exemplary embodiment. Figure 2 This is a three-dimensional structural diagram of a terminal according to an exemplary embodiment. Figure 3 This is a side view of the second antenna of a terminal according to an exemplary embodiment. Figure 4 This is a side view structural diagram of the first metal frame of a terminal according to an exemplary embodiment. Figure 9 This is a three-dimensional structural diagram of a terminal according to an exemplary embodiment.

[0060] like Figures 1 to 4 as well as Figure 9As shown, the terminal 30 provided in this disclosure includes a metal frame 110, a first antenna, and a second antenna 20. In some embodiments, the terminal 30 provided in this disclosure may further include a mid-frame 10, which may be made of metal, plastic, or a combination of both. This disclosure does not impose any specific limitations.

[0061] The metal frame 110 disclosed herein may include a first metal frame 111, and the space adjacent to the first side of the first metal frame 111 is the antenna clearance 120 of the terminal 30. The first side of the first metal frame 111 may be the inner side of the first metal frame 111, that is, the side of the first metal frame 111 located inside the terminal 30, and the first side may be disposed opposite to the middle frame 10.

[0062] In this disclosure, the antenna clearance 120 is the space inside the terminal 30 that is free from interference and can transmit and receive antenna signals. The antenna clearance 120 may be the space located between the metal frame 110 and the middle frame 10.

[0063] In this disclosure, the first metal frame 111 can be configured as the antenna radiator of the first antenna. For example, a slit 130 can be provided in the first metal frame 111 to radiate antenna signals to the outside of the terminal through the slit 130, thereby forming the first antenna.

[0064] In this disclosure, the second antenna 20 may be disposed at the antenna clearance 120, and the antenna frequency of the first antenna is different from the antenna frequency of the second antenna 20. For example, in an exemplary embodiment of this disclosure, the antenna frequency of the first antenna is one of 700-960MHz, 1500-2200MHz, and 2300-2700MHz; and / or the antenna frequency of the second antenna is 30-300GHz.

[0065] This disclosure provides a structurally integrated millimeter-wave and low-frequency metal-frame mobile phone antenna. A mirrored dielectric leaky wave antenna is arranged within the clearance area of ​​the metal-frame antenna, and a portion of the radiator of the frame antenna serves as the metal ground of the mirrored dielectric antenna, achieving spatial structural reuse. Simultaneously, due to the significant frequency difference between the low-frequency antenna (700-960MHz) and the millimeter-wave antenna, they can maintain good isolation, meaning they will not interfere with each other.

[0066] In one embodiment, Figure 8 This is a structural diagram of the first antenna of a terminal according to an exemplary embodiment, such as... Figure 8As shown, the first antenna can be an IFA antenna. Specifically, the ground of the first antenna can be the middle frame 10, and the first metal frame 111 can be formed in an F shape, or can be set to other shapes suitable for the IFA antenna radiator. The feed 140 of the first antenna can be set on the first side of the first metal frame 111. It should be noted that this disclosure is not limited to this, and in other possible embodiments, the first antenna can also be an antenna other than an IFA antenna.

[0067] In an exemplary embodiment of this disclosure, the first metal frame 111 is configured as the ground of the second antenna 20, and a first dielectric 210 is disposed on a first side of the first metal frame 111, which is configured as a transmission line of the second antenna 20. Specifically, in this disclosure, the first metal frame 111 is used as the ground of the second antenna 20, and the first dielectric 210 can be an image guide transmission line of the second antenna 20. However, this disclosure is not limited to this; in other possible embodiments, the first dielectric can also be configured as other types of transmission lines of the second antenna 20, as long as the configuration of the second antenna is satisfied.

[0068] The power supply 230 for the second antenna can also be located on the first side of the first metal frame 111, for example, adjacent to the first medium 210. However, this disclosure is not limited to this, and the power supply 230 for the second antenna can also be located at other positions on the first side.

[0069] In an exemplary embodiment of this disclosure, the antenna clearance 120 may be filled with a second dielectric material, wherein the dielectric constant of the first dielectric material is greater than the dielectric constant of the second dielectric material. For example, in an exemplary embodiment of this disclosure, the dielectric constant of the first dielectric material may be greater than or equal to 6.5, and the dielectric constant of the second dielectric material may be less than or equal to 3.5.

[0070] In this disclosure, the first dielectric can be a high-dielectric material, such as a ceramic, specifically rutile (TiO2) ceramic, or a composite oxide ceramic containing titanium dioxide, such as one or more of calcium titanate, magnesium titanate, and barium titanate. Under the influence of an external electric field, the high-dielectric material can generate a strong additional electric field opposite to the external electric field, and its strength increases with the increase of the external electric field. Therefore, the high-dielectric material can significantly improve the non-uniformity of the electric field at cable joints and terminals. Simultaneously, the low dielectric loss of the material provides good heat dissipation for cable joints and terminals. The high-dielectric material has excellent energy storage and uniform electric field properties, which can improve the heating properties of capacitors while greatly reducing the size and weight of capacitors, making it suitable for terminal manufacturing.

[0071] In this disclosure, the second medium can be a low-dielectric material, such as plastic, resin, etc.

[0072] In an exemplary embodiment of this disclosure, the second antenna 20 may include one or more radiating elements, each including a first portion 240 and a second portion 220. The first portion 240 may be disposed on the first metal frame 111, and the second portion 220 may be disposed on the first medium 210 at a position corresponding to the first portion 240. In this case, the first portion 240 and the second portion 220 are correspondingly disposed, and it can be assumed that the shapes of the first portion 240 and the second portion 220 are identical. Furthermore, in a direction perpendicular to the plane of the first metal frame 111, the projections of the first portion 240 and the second portion 220 onto the first metal frame 111 overlap.

[0073] In this disclosure, such as Figures 1 to 4 As shown, the thickness direction of the terminal 30 can be the x-direction, the length direction can be the y-direction, and the width direction can be the z-direction. For example, in an exemplary embodiment of this disclosure, the plane containing the first side of the first metal frame 111 can be parallel to the thickness direction of the terminal 30.

[0074] However, this disclosure is not limited to this. In some embodiments, the plane on which the first side of the first metal frame is located can also be perpendicular to the thickness direction of the terminal, that is, it can be parallel to the plane formed by the y-direction and the z-direction.

[0075] In an exemplary embodiment of this disclosure, the first part 240 may be a first through hole disposed in the first metal frame 111, and the second part 220 may be a second through hole disposed in the first dielectric 210. In this case, the second antenna 20 may be a leaky wave antenna.

[0076] However, this disclosure is not limited thereto. In some embodiments, the first part may also be a protrusion disposed on the first metal frame, and the second part may be a metal patch disposed on the first medium. In this case, the thickness of the protrusion and the metal patch may be the same, thus forming a leaky antenna.

[0077] Alternatively, in some embodiments, the second part 220 may also be formed by slotting the first medium 210 in the x-direction. In this case, the first part 240 may still be formed in the form of a through hole on the first metal frame 111.

[0078] In an exemplary embodiment of this disclosure, a plurality of radiating elements may be arranged at intervals along the length direction of the first metal frame 111, specifically, at intervals along the z-direction. However, this disclosure is not limited thereto; in some embodiments, the second antenna may also be configured to include only one radiating element.

[0079] In an exemplary embodiment of this disclosure, the width of the first medium 210 is A, where the width can be the length of the first medium 210 in the x-direction. For example... Figure 3 and Figure 4As shown, the first part 240 and the second part 220 of the radiating element can be circular through-holes, and the radius of the circular through-holes can be set to be greater than 0.5 Å. However, this disclosure is not limited to this. In other embodiments, the shape and size of the radiating element can be specifically set according to the coverage frequency band of the second antenna. Specifically, the shape and size of the radiating element can be determined according to the radiation efficiency and gain of the second antenna, for example, according to the radiation required by the main lobe and side lobes of the beam formed by the second antenna. In the embodiments of this disclosure, there can be three radiating elements.

[0080] exist Figure 3 and Figure 4 As shown, the spacing dx between multiple radiating elements can be equal, meaning that the multiple radiating elements can be uniformly distributed on the first medium 210. Furthermore, as shown in Figures 3 and 4... Figure 4 As shown, the multiple first parts 240 and the multiple second parts 220 are of the same shape and size, but this disclosure is not limited thereto.

[0081] Figure 5 This is a side view of the second antenna of a terminal according to another exemplary embodiment. Figure 6 This is a side view of the second antenna of a terminal according to another exemplary embodiment. Figure 7 This is a side view of the second antenna of a terminal according to another exemplary embodiment.

[0082] like Figure 5 As shown in the exemplary embodiments of this disclosure, the sizes of the multiple radiating elements can be different. Figure 6 As shown, the shapes of the first and second parts of the radiating unit can be non-circular, and can also be triangular, rectangular, or other shapes. For example... Figure 7 As shown in the exemplary embodiments of this disclosure, the spacing between two adjacent radiating elements may be different.

[0083] This disclosure utilizes the antenna clearance area of ​​a first antenna configured as a frame antenna, and also sets up a second antenna within the antenna clearance area. This enables multiplexing of the internal spatial structure of the terminal, allowing the terminal's antenna to cover more frequency bands and improving the terminal's antenna coverage range. Furthermore, the antenna frequency of the second antenna in this disclosure is different from that of the first antenna, which ensures sufficient isolation between the first and second antennas, preventing interference between them and thus improving the terminal's antenna performance.

[0084] In this disclosure, a mirrored dielectric waveguide antenna suitable for millimeter-wave band operation is structurally integrated with a common mid-to-high frequency metal frame antenna, thereby increasing millimeter-wave communication capabilities while saving internal space in the mobile phone. Due to the structural characteristics of the mirrored dielectric waveguide antenna, the clearance area of ​​the mid-to-high frequency metal frame antenna remains dielectric after structural integration, which has minimal impact on its performance; at the same time, the frequency difference between the mid-to-high frequency and millimeter-wave bands is significant, resulting in minimal mutual influence between their performance.
