Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
An antenna assembly 20 according to an embodiment of the present invention is described below with reference to the drawings. As shown in fig. 1, an antenna assembly 20 according to an embodiment of the present invention includes a first antenna 21, a second antenna 22, and a conductive spacer 23.
The distal end 211 of the first antenna 21 and the distal end 221 of the second antenna 22 are spaced apart in a first predetermined direction, and a slot 24 is defined between the distal end 211 of the first antenna 21 and the distal end 221 of the second antenna 22. At least a portion of the conductive spacer 23 is located between the end 211 of the first antenna 21 and the end 221 of the second antenna 22 in the first predetermined direction. Wherein one end of the conductive spacer 23 is adjacent to the slit 24 or a portion of the conductive spacer 23 is located within the slit 24.
The antenna assembly 20 according to the embodiment of the present invention can reflect and/or diffract the electromagnetic waves emitted from the first antenna 21 and the second antenna 22 by using the conductive spacer 23 by disposing the conductive spacer 23 between the end 211 of the first antenna 21 and the end 221 of the second antenna 22, so that the transmission of the electromagnetic waves between the first antenna 21 and the second antenna 22 is blocked, thereby effectively improving the isolation.
As shown in fig. 2, the antenna assembly 20 according to the embodiment of the present invention can significantly improve the isolation as compared to the antenna assembly of the related art that is not provided with the conductive spacer 23. For example, when the frequency is 1.8242GHz, the isolation of the antenna assembly 20 according to an embodiment of the present invention is 5.6dB less than that of the antenna assembly of the related art in which the conductive spacer 23 is not provided.
Further, as shown in fig. 2, since the conductive spacer 23 can improve the isolation, the conductive spacer 23 can intercept electromagnetic waves having a low frequency.
Therefore, the antenna assembly 20 according to the embodiment of the present invention has the advantages of high isolation, low design difficulty, good performance, and the like.
As shown in fig. 1, an electronic device 1 according to an embodiment of the present invention includes a body 10 and an antenna assembly 20, the antenna assembly 20 being provided on the body 10.
Therefore, the electronic device 1 according to the embodiment of the present invention has the advantages of high antenna isolation, small antenna design difficulty, good antenna performance, and the like.
Alternatively, the electronic device 1 according to the embodiment of the present invention may be a mobile phone, a tablet computer, or the like.
As shown in fig. 1, the electronic device 1 includes a body 10 and an antenna assembly 20, the antenna assembly 20 including a first antenna 21, a second antenna 22, and a conductive spacer 23, i.e., the conductive spacer 23 is made of a conductive material. Each of the first antenna 21 and the second antenna 22 is provided on the body 10.
The distal end 211 of the first antenna 21 and the distal end 221 of the second antenna 22 are spaced apart in a first predetermined direction, and a slot 24 is defined between the distal end 211 of the first antenna 21 and the distal end 221 of the second antenna 22. Wherein, the first preset direction may be one of a length direction and a width direction of the body 10. In other words, the end 211 of the first antenna 21 and the end 221 of the second antenna 22 may be spaced apart in one of the length direction and the width direction of the body 10. The first predetermined direction is shown by arrow a in fig. 1.
The size of the gap 24 in the first predetermined direction may be constant or may vary. Alternatively, the slot 24 is a rectangular slot (as shown in fig. 1) or a trapezoidal slot.
At least a portion of the conductive spacer 23 is located between the end 211 of the first antenna 21 and the end 221 of the second antenna 22 in the first predetermined direction. Optionally, the entire conductive spacer 23 is located between the end 211 of the first antenna 21 and the end 221 of the second antenna 22 in the first predetermined direction.
One end of the conductive spacer 23 is adjacent to the slit 24, i.e. the conductive spacer 23 does not extend into the slit 24. When one end of the conductive spacer 23 is adjacent to the slot 24, the conductive spacer 23 can reflect and/or diffract the electromagnetic waves emitted from the first antenna 21 and the second antenna 22 so as to block the transmission of the electromagnetic waves between the first antenna 21 and the second antenna 22, thereby effectively improving the isolation.
In the case where the conductive spacer 23 does not protrude into the slot 24, the smaller the minimum distance of the conductive spacer 23 from the slot 24, the higher the isolation of the antenna assembly 20. Optionally, the minimum distance of the conductive spacer 23 from the slit 24 is less than or equal to 1/5 wavelengths. That is, the minimum distance of the conductive spacer 23 from the slot 24 is related to the wavelength of the resonance.
Alternatively, a portion of the conductive spacer 23 is located within the slot 24. Wherein a portion of the conductive spacer 23 located within the slot 24 comprises: a. a portion of the conductive spacer 23 passes through the slit 24; b. the conductive spacer 23 does not pass through the slit 24.
Alternatively, when a portion of the conductive spacer 23 passes through the slit 24, the length of the portion of the conductive spacer 23 passing through the slit 24 may be equal to or less than 1/5 wavelengths. When the length of the portion of the conductive spacer 23 passing through the slot 24 is longer than 1/5 wavelengths, not only the isolation of the antenna assembly 20 cannot be increased any more, but also the appearance of the electronic device 1 may be affected.
Optionally, the conductive spacer 23 is grounded. This makes it possible to conduct the current on the conductive spacer 23 directly to the ground, and thus the isolation (isolation effect) can be further improved.
As shown in fig. 1, a first portion of the conductive spacer 23 is located in the slit 24, and a maximum dimension of the first portion (the portion of the conductive spacer 23 located in the slit 24) in the first predetermined direction is 10 μm to 10 mm. This can further improve the isolation (isolation effect).
Specifically, the conductive spacer 23 may be made by an LDS (Laser Direct Structuring-Laser Direct Structuring) process or a PDS (printed Direct Structuring) process.
Optionally, a ratio of a maximum dimension of the first portion in the first predetermined direction to a maximum dimension of the slit 24 in the first predetermined direction is less than or equal to 80%. That is, the maximum dimension of the first portion in the first predetermined direction is W1, the maximum dimension of the gap 24 in the first predetermined direction is W2, and W1/W2 is 80% or less. This can further improve the isolation (isolation effect).
For example, the maximum dimension of the first portion in the first predetermined direction may be the maximum thickness of the first portion, and the maximum dimension of the gap 24 in the first predetermined direction may be the maximum width of the gap 24.
Optionally, a ratio of a maximum dimension of the first portion in the first predetermined direction to a maximum dimension of the slit 24 in the first predetermined direction is greater than or equal to 10%, i.e., W1/W2 is greater than or equal to 10%. This can further improve the isolation (isolation effect).
Optionally, a ratio of a maximum dimension of the first portion in the first predetermined direction to a maximum dimension of the slit 24 in the first predetermined direction is greater than or equal to 30% and less than or equal to 50%, that is, W1/W2 is greater than or equal to 30% and less than or equal to 50%. This can further improve the isolation (isolation effect).
As shown in fig. 1, the conductive spacer 23 is a flat plate-like metal sheet. In other words, the conductive spacer 23 is flat and made of metal. The first predetermined direction is perpendicular to the plane of the conductive spacer 23. The structure of the conductive spacer 23 can thereby be made more rational.
For example, when the first preset direction is the length direction of the body 10, the conductive spacer 23 is parallel to each of the thickness direction and the width direction of the body 10; when the first preset direction is a width direction of the body 10, the conductive spacer 23 is parallel to each of a thickness direction and a length direction of the body 10.
As shown in fig. 1, the conductive spacer 23 has a first end 231 and a second end 232 opposite in a second preset direction, which may be the other of the length direction and the width direction of the body 10. In other words, the second predetermined direction may be perpendicular to the first predetermined direction. Wherein the first end 231 of the conductive spacer 23 is adjacent to the slot 24, or the first end 231 of the conductive spacer 23 is located in the slot 24, and the second end 232 of the conductive spacer 23 is grounded. The structure of the antenna assembly 20 can thereby be made more rational.
Alternatively, the first end 231 of the conductive spacer 23 may be an outer end of the conductive spacer 23 and the second end 232 of the conductive spacer 23 may be an inner end of the conductive spacer 23. The outer end of the conductive spacer 23 refers to an end of the conductive spacer 23 away from the center of the body 10, and the inner end of the conductive spacer 23 refers to an end of the conductive spacer 23 adjacent to the center of the body 10.
The end face of the first end 231 of the conductive spacer 23 is located inside the outer end of the slit 24 (the end of the slit 24 away from the center of the body 10). In other words, the conductive spacer 23 does not protrude out of the slit 24, and the end surface of the first end 231 of the conductive spacer 23 is not flush with the outer end of the slit 24. This makes it possible to provide the electronic apparatus 1 with a broken seam in the appearance thereof, so as to make the electronic apparatus 1 more beautiful.
The second end 232 of the conductive spacer 23 may be connected to the middle frame 11. For example, the second end 232 of the conductive spacer 23 may be welded to the middle frame 11, so as to weld the conductive spacer 23 to the middle frame 11. Alternatively, the conductive spacer 23 and the middle frame 11 are integrally formed. The structure of the electronic device 1 can thereby be made more rational.
