Description

Technical Field

[0001] This disclosure relates to the field of terminal technology, and in particular to an antenna structure and electronic device. Background Technology

[0002] With the rapid development of communication technology and the terminal industry, the demand for high-speed, low-latency, and high-throughput data service applications is becoming increasingly urgent. Based on this, fifth-generation mobile communication has emerged. China's three major operators have obtained nationwide licenses to use 5G mid- and low-frequency bands for trials. Therefore, the implementation of 5G antenna solutions suitable for various terminals has become particularly important and urgent.

[0003] Currently, smart terminals typically support 4G communication. However, to be compatible with 5G communication, 5G antennas need to be installed, which would drastically increase the number of antennas. Moreover, other functional electronic components within smart terminals already occupy a significant portion of the overall device space, making the installation and implementation of 5G antennas particularly difficult.

For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0034] Figure 1 This is a schematic diagram illustrating the structure of an antenna structure 100 according to an exemplary embodiment. For example... Figure 1 As shown, the antenna structure 100 can be applied to electronic devices, which can transmit and receive antenna signals through the antenna structure 100. The antenna structure 100 may include at least one first antenna radiator 1 and multiple second antenna radiators 2. The at least one first antenna radiator 1 can radiate 4G signals and is positioned close to a first edge of the electronic device. The multiple second antenna radiators 2 can radiate 5G antenna signals and are positioned close to a second edge of the electronic device, thus keeping them away from the first antenna radiator 1 and preventing overlap between the 4G and 5G antenna radiators. Furthermore, the antenna structure 100 may include at least one feed point 3, and the multiple second antenna radiators 2 can be connected to the same feed point to feed 5G signals to each second antenna radiator, simplifying the circuit layout within the electronic device. Of course, to feed antenna signals to the first antenna radiator 1, the at least one feed point may also include a feed point connected to the first antenna radiator 1. Figure 1 As not shown in the diagram, the first antenna radiator 1 may be connected to one or more feed points, and this disclosure does not impose any limitations on this.

[0035] As can be seen from the above embodiments, in this disclosure, the antenna radiator radiating 4G signals and the antenna radiator radiating 5G signals are disposed at different edges of the electronic device, so as to add 5G communication function while adapting to the antenna layout scheme in the existing related technical solutions; in this disclosure, multiple second antenna radiators 2 are connected to the same feed point, which helps to simplify the circuit layout of the antenna structure 100 and save the internal space of the electronic device that configures the antenna structure 100.

[0036] In one embodiment, still using Figure 1As shown, the multiple second antenna radiators 12 may include a first sub-radiator 21, a second sub-radiator 22, and a third sub-radiator 23. These three sub-radiators are connected to the same feed point, and all three are used to radiate 5G antenna signals. For example... Figure 1 As shown, the first antenna radiator 1 can be disposed in Figure 1 Above, therefore the first sub-radiator 21, the second sub-radiator 22, and the third sub-radiator 23 can be positioned. Figure 1 The left and right sides of the middle. Of course, in Figure 1 In this embodiment, only the antenna structure 100 including three second antenna radiators is used as an example for illustration. In other embodiments, such as Figure 2 As shown, the antenna structure 100 can also include four second antenna radiators, that is, the antenna structure can also include a fourth sub-radiator 24. The specific design can be customized as needed, and this disclosure does not impose any limitations on this. Furthermore, in Figure 2 In the embodiment shown, the first side edge corresponding to the electronic device can be used as the second side edge, and the edge adjacent to the first side edge can be used as the second side edge. Two second antenna radiators can be set at each second side edge position. The second antenna radiators set at the two second side edges can be symmetrically set or asymmetrically set. Each second antenna radiator can be connected to the same feed point through a coaxial line or microstrip transmission line.

[0037] Each second antenna radiator can be set to be relatively small to avoid excessively occupying the edge of the electronic device on which the antenna structure 100 is configured. For example, the second antenna radiator can adopt a size structure of 20mm×4.2mm×1mm. Of course, in other embodiments, the size of the second antenna radiator can also be appropriately changed according to design needs and radiation requirements. This disclosure does not limit this.

[0038] The following description will use a first sub-radiator 21 as an example to illustrate the specific structure of the second antenna radiator.

[0039] like Figure 3As shown, the first sub-radiator 21 may include a radiating body 211 and a coupling stub 212. The radiating body 211 can be connected to a feed point 3. Through impedance matching of the feed point 3 and the related matching circuit of the antenna structure 100, the radiating body 211 can be used to radiate antenna signals in the N79 frequency band. The coupling stub 212 is positioned close to the radiating body 211, i.e., there is a gap between the radiating body 211 and the coupling stub 212. The coupling stub 212 is grounded. By adjusting the grounding position on the coupling stub 212, the resonant frequency and impedance of the antenna structure 100 can be adjusted. Through coupling, the coupling stub 212 can radiate antenna signals in the N77 and N78 frequency bands, thereby achieving full network compatibility with the antenna structure 100 and enabling the search for 5G signals in overseas areas. The gap between the radiating body 211 and the coupling stub 212 can be greater than 0.5 mm, for example, it can be 0.8 mm, 1.2 mm, etc., and this disclosure does not impose any limitations on this.

[0040] In one embodiment, still using Figure 3 As shown, the radiating body 211 can be in the form of a monopole antenna, and at this time, as Figure 3 As shown, the coupling stub 212 may include a first stub 2121 arranged along a first direction and two second stubs 2122 arranged along a second direction. The two second stubs 2122 are respectively connected to the two ends of the first stub 2121, and the first direction and the second direction are perpendicular. The first stub 2121 is grounded. The position of the grounding point on the first stub 2121 relative to the entire coupling stub 212 is related to the resonant frequency of the antenna structure 100. The specific position of the grounding point can be determined according to specific debugging experiments, and this disclosure does not limit it.

[0041] In another embodiment, such as Figure 4 As shown, taking the first sub-radiator 21 as an example, the radiating body 211 of this first sub-radiator 21 can be an IFA antenna structure, which can be connected to the feed point and grounded. Further, in Figure 4 In the illustrated embodiment, the coupling stub 212 included in the first sub-radiator 21 may include a third stub 2123 arranged in a third direction, and a fourth stub 2124 connected to the third stub 2123 and extending in a fourth direction. The end of the fourth stub 2124 away from the third stub 2123 is grounded. The fourth direction is perpendicular to the third direction, and the third stub 2123 and the fourth stub 2124 are connected in a mutually perpendicular structure. The location of the grounding point on the fourth stub 2124 on the entire coupling stub 212 is related to the resonant frequency to be radiated by the second antenna radiator.

[0042] Compared to Figure 3 The illustrated embodiment, due to Figure 4In the embodiment shown, the radiating body 211 adopts an IFA antenna structure, therefore Figure 4 In the illustrated embodiment, the IFA antenna structure itself is provided with a grounding point, thus enabling the use of... Figure 4 The second antenna radiator 21 of the structure shown can be systematically positioned close to the antenna structure 100, reducing the space constraints within the electronic device in which the antenna structure 100 is configured. Figure 4 The structure of the coupling branch 212 in the implemented embodiment can also be... Figure 3 The radiating bodies in the embodiments cooperate to form a new antenna structure, and similarly, Figure 3 The structure of the coupling branch 212 in the implemented embodiment can also be... Figure 4 The radiating bodies in the embodiments cooperate to form a new antenna structure, but this disclosure does not limit this.

[0043] The antenna structure 100 described in the above embodiments, such as Figure 5 As shown, this disclosure also provides an electronic device 200, which may include the antenna structure described in any of the above embodiments. Furthermore, as... Figure 6 As shown, the electronic device 200 may include a metal frame 201. The electronic device 200 configuring the antenna structure 100 may include a metal frame 201. The first antenna radiator 1 and the second antenna radiator 2 of the antenna structure 100 may both be part of the metal frame 201. In particular, the radiating body part of the second antenna radiator may be part of the metal frame 201.

[0044] For example, still using Figure 6 As shown, the metal frame 201 may include multiple slots 2011, and each second antenna radiator may be located within a corresponding slot 2011. A gap is provided between the end of the second antenna radiator facing the edge of the slot and the inner wall of the slot 2011. When the second antenna radiator includes a radiating body and a coupling branch spaced apart from the radiating body, the coupling branch may be formed independently of the metal frame 201 near the radiating body using a laser forming process, or the coupling branch may be formed on the metal frame 201 using a CNC process. A gap is provided between the coupling branch and the radiating body in a direction perpendicular to the edge where the radiating body is located. The specific design can be customized as needed, and this disclosure does not impose any limitations on this.

[0045] For example, still using Figure 6As shown, the first antenna radiator of the antenna structure 100 can be disposed at the top and bottom of the electronic device 200, while the second antenna radiator is disposed on the left and right sides of the electronic device 200. This allows it to adapt to the 4G antenna layout in existing related technical solutions. Furthermore, a camera 202 and a distance sensor 203, among other related electronic components, can be disposed at the top of the electronic device 200, while a speaker 204 and a microphone 205, among other related electronic components, can be disposed at the bottom of the electronic device 200. Therefore, the antenna structure 100 of this disclosure, while equipped with 5G communication functionality, can simultaneously adapt to the existing layout of electronic devices in related technologies, thereby reducing production and design costs. The electronic device 200 may include mobile terminals, tablet terminals, and e-readers, etc., and this disclosure does not impose any limitations on this.

This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

The scope of this disclosure is limited only by the appended claims.
