Description
Technical Field
The application belongs to the technical field of electronic equipment, and particularly relates to electronic equipment.
Background
With the development of the age, mobile phones become almost a necessary device for hands, and more functions can be realized by the mobile phones. The realization of multiple functions on the mobile phone is independent of the electric connection between the mobile phone and various networks, and particularly, the design of the mobile phone antenna provides greater challenges along with the coming of the 5G age. In the limited space of the mobile phone, the 5GSub-6G frequency band is added on the basis of the traditional 4G frequency band, and the design of the MIMO technology, the WIFI_2G&5G 2x2,GPS,L1&L5 and other antennas is considered. In addition, the mobile phone not only needs to be provided with more antennas, but also needs to work independently and not interfere with each other.
In the related art, the mobile phone antenna is mainly distributed at the upper half and the bottom of the mobile phone, and the space occupied by the antenna layout is less than half of the volume of the whole mobile phone, and the main reason is that the feed end of the antenna needs to be placed on the PCB to excite the antenna, and the mobile phone has a large half of space occupied by related functional modules, such as a battery, a key, a loudspeaker, a receiver, a camera and the like, so that the layout of the antenna is limited.
In summary, how to find an antenna with a newly added 5G frequency band in a compact complete machine environment, and solve the problem of isolation between the 5G antenna and the 4G antenna, becomes an advancing direction of the design of the 5G mobile phone antenna system.
Disclosure of Invention
The application aims to provide an electronic device which at least solves one of the problems of position arrangement of a 5G antenna and isolation between the 5G antenna and a 4G antenna.
In order to solve the technical problems, the application is realized as follows:
an embodiment of the present application provides an electronic device, including:
a frame;
the first fracture and the second fracture are arranged on the frame;
the first key is arranged on the part, located between the first fracture and the second fracture, of the frame;
the part of the frame between the first fracture and the second fracture forms an antenna working in a first frequency band and a second frequency band, and the first frequency band and the second frequency band are different.
In the above embodiment, the portion of the frame located between the first break and the second break is provided with the first key, which is beneficial to ensure that a larger distance exists between the first break and the second break. And the part of the frame between the first fracture and the second fracture forms an antenna working in the first frequency band and the second frequency band, so that the first frequency band and the second frequency band can radiate signals from the first fracture and the second fracture respectively. And after the larger distance is arranged between the first fracture and the second fracture, the isolation between the two frequency bands is increased, and the mutual working influence and interference are reduced. Thus, when the first frequency band and the second frequency band are different, each can be independently operated.
In addition, as the first fracture and the second fracture are arranged on the frame and are arranged on the two sides of the first key, at least part of the antennas are arranged at the gaps among the frame, the battery plate and the main board, so that the components such as a battery, a loudspeaker and a receiver are avoided, or at least part of the antennas are directly arranged as a part of the frame, and therefore, under the condition that the volume of the electronic equipment is not required to be increased, the antennas working in the first frequency band and the second frequency band are found to be installed, the occupied space is small, and the original pattern of each component on the electronic equipment is basically not required to be changed.
Further, the first fracture and the second fracture are respectively arranged at two sides of the first key, when the antenna radiates signals outwards, the signals of the first frequency band can be radiated from the first fracture, and the signals of the second frequency band can be radiated from the second fracture, so that mutual interference between the two frequency bands can be reduced, and the independence of work between the first frequency band and the second frequency band is improved.

An electronic device 10 according to an embodiment of the application is described below in connection with fig. 1-6.
As shown in fig. 1 and 2, an electronic device 10 according to some embodiments of the present application includes a bezel 100, a first key 102, an antenna, a first break 108, and a second break 146.
The first break 108, the second break 146 and the first button 102 are all disposed on the bezel 100. The first key 102 is located between the first break 108 and the second break 146. The portion of the bezel 100 between the first break 108 and the second break 146 forms an antenna that operates in a first frequency band and a second frequency band, the first frequency band being different from the second frequency band.
In the above embodiment, the portion of the frame 100 between the first break 108 and the second break 146 is provided with the first key 102, which is advantageous in ensuring a large distance between the first break 108 and the second break 146. And the portion of the frame 100 located between the first break 108 and the second break 146 forms an antenna operating in the first frequency band and the second frequency band, so that the first frequency band and the second frequency band can respectively transmit and receive signals from the first break 108 and the second break 146, and after a larger distance is set between the first break 108 and the second break 146, the isolation between the two frequency bands is increased, and the mutual working influence and interference are reduced. Thus, when the first frequency band and the second frequency band are different, each can be independently operated.
In addition, since the first break seam 108 and the second break seam 146 are disposed on the frame 100 and disposed on two sides of the first key 102, it is beneficial to dispose at least part of the antennas at the gaps between the frame 100 and the panel or the motherboard, avoiding components such as a battery, a speaker, a receiver, etc., or directly disposing at least part of the antennas as a part of the frame 100, so that under the condition that the volume of the electronic device 10 is not required to be increased, suitable positions are found for the antennas of the first frequency band and the second frequency band for installation, and the occupied space is small, and the original pattern of each component on the electronic device 10 is basically not required to be changed.
Further, the first breaking seam 108 and the second breaking seam 146 are respectively disposed at two sides of the first key 102, when the antenna radiates signals outwards, the signals of the first frequency band can be radiated from the first breaking seam 108, and the signals of the second frequency band can be radiated from the second breaking seam 146, so that mutual interference between the two frequency bands can be reduced, and thus the independence of the operation between the first frequency band and the second frequency band can be improved.
In some embodiments, the first breaking seam 108 and the second breaking seam 146 are respectively spaced from the first key 102, so as to avoid the first key 102, avoid affecting the stability of the first key 102, and be compatible with the requirement of beautifying the appearance of the first key 102, thereby effectively digging the design space of the antenna.
Further, a second key 140 is further disposed on the frame 100. The second key 140 is located between the first key 102 and the second break 146. By providing the second key 140 between the first key 102 and the second break 146, the distance between the first break 108 and the second break 146 is further increased, so that the isolation between the first frequency band and the second frequency band can be correspondingly further increased, and the influence of mutual operation is reduced.
In some implementations, one of the first key 102 and the second key 140 is a power-on key of the electronic device 10 to control the opening and closing of the electronic device 10. The other is a volume key to control the volume of the electronic device 10.
It should also be noted that the keys of the electronic device 10, especially a mobile terminal such as a mobile phone, are generally disposed on a longer side of the frame 100. Since the first break 108 and the second break 146 are disposed on one side of the first key 102, the antenna is correspondingly disposed on the longer side of the frame 100. In other words, the antenna is disposed on the longer side of the frame 100, so that the antenna has a larger accommodating space, which is more beneficial to increasing the physical distance between the first break 108 and the second break 146, thereby further improving the isolation between the first frequency band and the second frequency band.
Further, the electronic device 10 includes a battery compartment area and a motherboard area. The battery compartment area and the main board area are provided in the area surrounded by the frame 100.
In some embodiments, the first break 108 is located at a position opposite the battery compartment 180 of the bezel 100. The second break 146 is located at a position opposite the main panel region 182 of the bezel 100. It will be appreciated that in the electronic device 10, the battery and the motherboard occupy a larger space, the first break seam 108 is located at the side frame 100 opposite to the battery compartment area 180, and the second break seam 146 is located at the side frame 100 opposite to the motherboard area 182, which is beneficial to ensure a larger distance between the first break seam 108 and the second break seam 146, so as to maintain a better isolation between the first frequency band and the second frequency band.
Further, as shown in fig. 1 and 2, in an electronic device 10 according to other embodiments of the present application, the antenna includes a first antenna 104 operating in a first frequency band and a second antenna 142 operating in a second frequency band.
The first antenna 104 may radiate signals using the first discontinuity 108 and the second antenna 142 may radiate signals using the second discontinuity 146.
After the first antenna 104 is designed, the second antenna 142 is designed to be complementary, which is beneficial to realizing the antenna system scheme with the coexistence of the first frequency band and the second frequency band. Further, the first frequency band is a 4G frequency band, that is, the first antenna 104 operates in the 4G frequency band. The second frequency band is a 5G frequency band, i.e., the second antenna 142 operates in the 5G frequency band. Thus, the antenna system scheme with the coexistence of 4G/5G frequency bands can be realized.
Specifically, the first antenna 104 includes a first feeding portion 110. The first power feeding portion 110 is provided at a position corresponding to the first key 102. And the first feeding portion 110 is located in the main board region 182, so that the first feeding portion 110 can be integrated on the main board in the main board region 182, and the overlong circuit of the first feeding portion 110 can be avoided, which is beneficial to simplifying the circuit structure and saving the space.
In some embodiments, the first break 108 is located on the bezel 100 opposite the battery compartment area 180 and the second break 146 is located on the bezel 100 opposite the main panel area 182. It will be appreciated that in the electronic device 10, the battery and motherboard occupy a relatively large space, the first break 108 is opposite the battery compartment 180, and the second break 146 is opposite the motherboard 182, which advantageously ensures a relatively large distance between the first break 108 and the second break 146, thereby enabling a sufficient physical distance between the first antenna 104 and the second antenna 142 to maintain a relatively good isolation between the first antenna 104 and the second antenna 142.
The first antenna 104 further includes a first ground 106, a second ground 112, a first main structure, and a first parasitic structure.
Specifically, the first grounding portion 106 and the second grounding portion 112 are both disposed on the frame 100. The first grounding portion 106 is located on a side of the first break 108 away from the first key 102. The second grounding portion 112 is disposed on a side of the first feeding portion 110 away from the first grounding portion 106. The portion of the frame 100 from the second grounding portion 112 to the first break 108 forms a first main structure. A portion of the first main structure is disposed opposite the battery compartment area 180 and another portion of the first main structure is disposed opposite the main panel area 182. In this way, the first main structure spans both the battery compartment area 180 and the main board area 182 and is formed by a portion of the frame 100, such that a portion of the first antenna 104 does not occupy additional space, thereby saving space. Accordingly, a portion of the frame 100 from the first grounding portion 106 to the first break 108 forms a first parasitic structure, and the first parasitic structure is disposed opposite to the battery compartment 180. That is, the first parasitic structure is also formed by a portion of the frame 100, and does not occupy additional space. Thus, the first antenna 104 can be arranged with sufficient space to ensure stability and reliability of its operation.
Still further, the first antenna 104 also includes a first matching network 114 and a switching network 116. The switching network 116 is connected to the first matching network 114. Further, the first matching network 114 and the switching network 116 are disposed between the first feeding portion 110 and the frame 100, and the first matching network 114 and the switching network 116 are both connected to the first feeding portion 110 and also are both connected to the frame 100. With the structure, the first break 108 to the second grounding part 112 and the first break 108 to the first feeding part 110 can be excited to cover the MHB frequency band by two 1/4 wavelength mode currents, meanwhile, parasitic resonance is usually in the B41 frequency band, the influence of switching is small, and the CA requirements of B3_41 and B39_41 can be met.
Further, the distance between the first break 108 and the first key 102 is 4 mm-6 mm, for example, one of 4mm, 5mm, and 6 mm. The distance between the first break 108 and the first power feeding portion 110 is 12mm to 16mm, for example, one of 13mm, 14mm, and 15 mm. The distance between the first break 108 and the first feeding portion 110 refers to a distance along the direction from the first key 102 to the second key 140. The distance between the first grounding portion 106 and the first break 108 is 12mm to 16mm, for example, one of 13mm, 14.3mm, and 15 mm. The distance between the second grounding portion 112 and the first power feeding portion 110 is 8mm to 10mm, for example, one of 8mm, 9mm, and 10 mm.
It will be appreciated that the above-described size limitation ensures the radiation performance of the first antenna 104, i.e. ensures the stability and reliability of the antenna to receive and transmit signals. The above-mentioned size limitation is mainly determined by the performance requirements of the first antenna 104 itself, and has no direct connection with the size of the electronic device 10.
The second antenna 142 includes a second feeding portion 148, and the second feeding portion 148 is disposed at a position corresponding to the second key 140 and may be located in the main board area.
By disposing the first feeding portion 110 at a position corresponding to the first key 102 and the second feeding portion 148 at a position corresponding to the second key 140, a larger distance between the first feeding portion 110 and the second feeding portion 148, and correspondingly, a larger distance between the first antenna 104 and the second antenna 142, is enabled.
Further, the second feeding portion 148 is located in the main board region 182. Such a structure facilitates integration of the second feeding portion 148 on the motherboard within the motherboard region 182, and can avoid excessive circuit length of the second feeding portion 148, thereby facilitating simplification of circuit structure and space saving.
The second antenna 142 further includes a third ground 144, a fourth ground 150, a second main structure, a second parasitic structure, and a second matching network 152.
Specifically, the third grounding portion 144 is disposed on the frame 100 and is located on a side of the second break 146 away from the second key 140. The fourth grounding portion 150 is also disposed on the frame 100, and is disposed on a side of the second feeding portion 148 away from the third grounding portion 144. And the distance between the fourth grounding portion 150 and the second feeding portion 148 is smaller than the distance between the second grounding portion 112 and the second feeding portion 148, which is beneficial to ensuring that the fourth grounding portion 150 can be closer to the second feeding portion 148, and further beneficial to ensuring that the first antenna 104 and the second antenna 142 can keep a certain physical distance without crossing together, so that better isolation between the two antennas can be ensured.
In some specific applications, the distance between the second grounding portion 112 and the fourth grounding portion 150 is 5mm or more. When the distance between the second grounding portion 112 and the fourth grounding portion 150 is greater than 5mm, the isolation between the first antenna 104 and the second antenna 142 is less than-12 dB. And when the distance between the second ground portion 112 and the fourth ground portion 150 is greater than 12mm, the isolation between the first antenna 104 and the second antenna 142 is less than-16 dB. That is, as the physical distance between the first antenna 104 and the second antenna 142 increases, the isolation of the two is correspondingly increased. In addition, the structure between the second grounding part 112 and the fourth grounding part 150 is also a key implementation structure of the antenna scheme compatible with the appearance of the keys, and by adjusting the distance between the second grounding part 112 and the fourth grounding part 150, the distance between the two breaks and each key can be correspondingly adjusted, so that the antenna can be compatible with the layout of each key, and the appearance of the whole antenna can be beautified.
Further, a portion of the frame 100 from the fourth grounding portion 150 to the second break 146 forms a second main structure. The second main structure bit is disposed opposite the main board region 182. The portion of the frame 100 from the third grounding portion 144 to the second break 146 forms a second parasitic structure. The second parasitic structure is disposed opposite the main board region 182. The second main structure and the second parasitic structure are disposed opposite the main board region 182, such that the second main structure and the second parasitic structure are also formed by constructing a portion of the frame 100, such that the two portions of the first antenna 104 do not occupy additional space, thereby saving space. The second main structure and the second parasitic structure are disposed opposite the main board region 182, and thus, most of the second antenna 142 is opposite the main board region 182, and is significantly separated from the first antenna 104, so that the second antenna 142 can have sufficient space to be disposed to ensure the stability and reliability of the operation thereof.
The second matching network 152 is disposed between the second feeding portion 148 and the frame 100, so as to excite three 1/4 wavelength mode currents from the second grounding portion 112 to the second break gap 146, from the second feeding portion 148 to the second break gap 146, and from the second break gap 146 to the third grounding portion 144 to cover three N41/78/79 frequency bands of the sub 6G.
Further, the distance between the second slit 146 and the second power feeding portion 148 is 5mm to 9mm, for example, one of 6mm, 6.7mm, and 8 mm. The distance between the second slit 146 and the second feeding portion 148 refers to a distance along the direction from the first key 102 to the second key 140. The distance between the third grounding portion 144 and the second break line 146 is 3mm to 6mm, for example, one of 3mm, 4mm, 4.7mm, and 5mm. The distance between the second break 146 and the fourth ground portion 150 is 11mm to 15mm, for example, one of 12mm, 13mm, and 14 mm.
It will be appreciated that the above-described size limitation ensures the radiation performance of the second antenna 142, i.e., ensures the stability and reliability of the antenna to receive and transmit signals. The above size limitation is primarily determined by the performance requirements of the second antenna 142 itself, and is not directly related to the size of the electronic device 10.
In any of the above embodiments, the distance from the first break 108 to the edge of the bezel 100 is greater than the distance from the first break 108 to the first key 102. Meanwhile, the distance from the second break 146 to the edge of the frame 100 is greater than the distance from the second break 146 to the second key 140. In this way, the two breaking seams are far away from the edge of the frame 100, or the two breaking seams are far away from the bottom and the top of the frame 100, and when a user holds the electronic device 10 vertically or holds the electronic device 10 horizontally, the two breaking seams are not easy to shield, that is, the antenna radiation signals are not shielded, so that the antenna performance of the user when using the electronic device 10 can be effectively ensured.
In any of the above embodiments, the electronic device 10 comprises at least one of: mobile terminals, tablet computers, notebook computers, televisions, digital cameras, electronic book readers, electronic game machines, personal digital assistants.
The present application will be described below by taking a mobile phone as an example.
The application provides a mobile phone. The mobile phone side keys comprise volume keys and break seams at two sides of a starting key, under the condition that key functions and appearance are not affected, two antennas are designed in an area which is not easy to design, and the two antennas are respectively covered with a 4G MHB band (the MHB band comprises an MB band and an HB band, the MB band can be 1500 MHz-2200MHz, the HB band can be 2300 MHz-2700 MHz) and a 5G sub-6G band, so that the problem of space shortage of the design of the 5G mobile phone antenna is solved. The two antennas are reasonably designed with the antenna structure, the feed, the grounding and the matching network of the antennas, so that the antenna radiation modes corresponding to the required working frequency band can be excited, the two antennas are mutually independent, and the isolation degree is good.
Fig. 1 is a schematic diagram of a partial structure of an electronic device 10 according to an embodiment of the present application. As shown in fig. 1, a frame 100 of a mobile phone is provided with a first key 102 and a second key 140. Wherein the first key 102 is a mobile phone power key and the second key 140 is a mobile phone volume key. A first break 108 is provided on one side of the first key 102, and a second break 146 is provided on a side of the second key 140 remote from the first key 102. The first break 108 and the second break 146 serve as key structures for antenna radiation.

As shown in fig. 2, the principle of the whole antenna scheme design is as follows: the first antenna 104 implements the 4G MHB band (B3/2/1/39/40/41) and the second antenna 142 implements the sub-6G band (N41/78/79). The two antennas independently coexist, so that the simultaneous operation of the 4G MHB frequency band and the 5G sub-6G frequency band can be realized, and the first antenna 104 can meet B3_41CA and B39_41CA.
In the application, the mobile phone mainly comprises a battery compartment area 180 and a main board area 182. The location between the battery compartment area 180 and the main board area 182 is the boundary area 184 between the main board area 182 and the battery compartment area 180. The first break 108 and the first parasitic structure are completely distributed in the region of the battery compartment area 180. The position of the first break 108 is about 14mm from the first feeding portion 110 due to the appearance requirement of the first key 102, that is, about 5mm below the first key 102, so that the first antenna 104 realized by performing feeding in combination with matching tuning of the antenna in the edge area of the main board can meet the frequency band coverage of the 4G MHB antenna. The first antennas 104 are distributed on the side edges of the mobile phone, and most of the antenna structures are in the battery compartment area 180, but the battery compartment structure is not affected, and the design of the antennas avoids the layout of keys and the appearance beautifying requirements of the keys, so that the design space of the mobile phone antennas is effectively excavated. By the complementary combination with the second antenna 142, a 4G/5G frequency band coexisting antenna system scheme is realized.
In the application, the first antenna 104 and the second antenna 142 are distributed on the side frames of the whole machine, and the first break seam 108 and the second break seam 146 are far away from the top and the bottom of the mobile phone, so that the mobile phone is not easy to be held by a human hand in a vertical holding state and a horizontal holding state of the user, and thus, the antenna performance of the user during hand-held communication or data interaction and game playing can be effectively ensured.
As shown in fig. 2, in the present application, the radiation structure of the first antenna 104 is a structure between the first ground portion 106 and the second ground portion 112. A section of the frame 100 between the first ground portion 106 and the first break 108 is a parasitic structure of the first antenna 104, that is, a first parasitic structure, and has a length of 14.3mm. The first feeding portion 110 is disposed near the top of the first key 102. A section of the frame 100 between the first break 108 and the second ground portion 112 is a main structure of the first antenna 104, where a length from the first break 108 to the first feeding portion 110 is about 14 mm. The length between the first power feeding portion 110 and the second ground portion 112 is about 9 mm. The matching network and the switch switching network 116 are combined at the first feeding part 110, so that two 1/4 wavelength mode currents from the first break joint 108 to the second grounding part 112 and from the first break joint 108 to the first feeding part 110 can be excited to cover the MHB frequency band, parasitic resonance is common to B41, the influence of switch switching is small, and CA requirements of B3_41 and B39_41 can be met. Fig. 3 shows S11 parameters of the first antenna 104, and fig. 4 shows a system efficiency diagram of the first antenna 104.
As shown in fig. 2, in the present application, the radiating structure of the second antenna 142 is a structure between the third ground portion 144 and the fourth ground portion 150. The second break 146 to the third ground portion 144 are parasitic structures of the second antenna 142, that is, the second parasitic structure, and have a length of about 4.7 mm. The second feeding portion 148 is disposed between the fourth grounding portion 150 and the second break slit 146. The section of the frame 100 between the fourth grounding portion 150 and the second break 146 is the main structure of the second antenna 142, wherein the length between the fourth grounding portion 150 and the second break 146 is about 13 mm. The length from the second power feeding portion 148 to the second slit 146 is about 6.7 mm. At the location of the second feeding portion 148, the feeding incorporates a matching network capable of exciting three 1/4 wavelength mode currents of the fourth ground portion 150 to the second break 146, the second feeding portion 148 to the second break 146, and the second break 146 to the third ground portion 144 to cover three N41/78/79 frequency bands of sub 6G. Fig. 5 shows S11 parameters and system efficiency of the second antenna 142.
In the present application, the distance between the second ground portion 112 and the fourth ground portion 150 is used as a physical isolation ground space between the first antenna 104 and the second antenna 142, when the distance between the second ground portion 112 and the fourth ground portion 150 is greater than 5mm, the isolation between the two antennas can be less than-12 dB, and when the distance between the second ground portion 112 and the fourth ground portion 150 is greater than 12mm, the isolation between the two antennas is less than-16 dB. In addition, the structure of the distance between the second grounding part 112 and the fourth grounding part 150 is also a key implementation structure of the antenna scheme compatible with the appearance of the key, and the distance between the two breaks and the key can be adjusted by adjusting the size of the distance between the second grounding part 112 and the fourth grounding part 150, so that the layout of the key can be compatible, and the appearance of the whole machine can be beautified. Fig. 6 shows the isolation of the first antenna 104 and the second antenna 142 at different lengths of the distance of the second ground 112 from the fourth ground 150.
