Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an antenna assembly 100 includes a first antenna 10, a second antenna 20, and a reference ground 30. The first antenna 10 and the second antenna 20 are used for receiving and transmitting electromagnetic waves, and may be any type of antenna, such as an F antenna, a dipole antenna, a monopole antenna, a single frequency antenna, and the like.
The first antenna 10 and the second antenna 20 may be implemented in any communication manner, for example, the first antenna 10 and the second antenna 20 may be a bluetooth antenna, a WIFI antenna, an NFC antenna, and the like. The first antenna 10 and the second antenna 20 may be implemented in the same communication scheme or may be implemented in different communication schemes. The first antenna is a WIFI antenna, and the second antenna is a bluetooth antenna.
The reference ground 30 connects the first antenna 10 and the second antenna 20 such that a current signal fed by the first antenna 10 flows into the reference ground 30 via the first antenna 10, and a current signal fed by the second antenna 20 flows into the reference ground 30 via the second antenna 20 to form a feed closed loop of the current signal.
The reference ground 30 includes a first connection portion 31, a second connection portion 32, and a communication portion 33. The first connection portion 31 is connected to the first antenna 10, the second connection portion 32 is connected to the second antenna 20, and both the first connection portion 31 and the second connection portion 32 communicate with the communication portion 33. The communication portions 33 connect the first connection portion 31 and the second connection portion 32, respectively, such that the first connection portion 31, the second connection portion 32, and the communication portion 33 communicate with each other, forming a communication area as a whole. So that the first antenna 10 and the second antenna 20 have the same reference ground.
Referring to fig. 1, a groove is disposed on the reference ground 30, and a concave portion of the groove forms the first space region 40 on the reference ground 30, so that the first space region 40 is spaced between the first connecting portion 31 and the second connecting portion 32. The first spatial region 40 isolates the first connection portion 31 from the second connection portion 32. Further, the first space region 40 extends in a direction away from the first antenna 10 and the second antenna 20, and the first space region 40 extends out of the first antenna 10 and the second antenna 20.
Alternatively, the first space region 40 extends from the antenna in a direction toward the reference ground (please refer to the Y direction in fig. 2) beyond the first antenna 10 and the second antenna 20. As such, the first spatial region 40 may change the current direction, and the currents in the first antenna 10 and the second antenna 20 may flow along the excess portion (i.e., the portion of the first spatial region 40 that extends beyond the first antenna 10 or the second antenna 20) without causing the current of the first antenna 10 to flow to the second antenna 20 through the reference ground, or the current of the second antenna 20 to flow to the first antenna 10 through the reference ground. Interference between the first antenna 10 and the second antenna 20 can be reduced.
Referring to fig. 2, due to the first space region 40, the current flows downward in the arrow direction shown in fig. 2, rather than flowing laterally, so that the current of the first antenna 10 can be prevented from flowing to the second antenna 20 through the reference ground or the current of the second antenna 20 can flow to the first antenna 10 through the reference ground to some extent.
It should be noted that fig. 1 illustrates the first antenna 10 and the second antenna 20 only by way of example, and in other embodiments, a third antenna or more antennas may be further included, and the reference ground 30 may also include a third connection portion or more connection portions, where each adjacent connection portion is separated by a space region, for example, a second space region is separated between the second connection portion and the third connection portion.
The cross-section of the reference ground 30 is illustratively shown in fig. 1 as being generally rectangular, and in other embodiments, the reference ground 30 may be other shapes, such as trapezoidal, etc. The first antenna 10 and the second antenna 20 are "L" -shaped antennas, and in other embodiments, the first antenna 10 and the second antenna 20 may be antennas with other shapes. In the embodiment shown in fig. 1, the cross-section of the first spatial region 40 is generally rectangular, and in other embodiments, the cross-section of the first spatial region 40 may be other shapes, such as trapezoidal, etc.
In the embodiment shown in fig. 1, the first antenna 10 and the second antenna 20 are disposed above the reference ground 30, and in other embodiments, the first antenna 10 may be disposed in an upward direction on the left side of the reference ground 30, and the second antenna 20 may be disposed in an upward direction on the right side of the reference ground 30, where the above may be a direction away from the reference ground 30.
Referring to fig. 3 and 4, the reference ground 30 may further include a first extension 34 and a second extension 35. The first extension portion 34 communicates with the first connection portion 31, and the second extension portion 35 communicates with the second connection portion 32. The first extension portion 34 extends from the first connection portion 31 in the direction of the first antenna 10, and the second extension portion 35 extends from the second connection portion 32 in the direction of the second antenna 20.
Wherein the first extension 34 and the second extension 35 are used to isolate the first antenna 10 and the second antenna 20. In this way, electromagnetic energy radiated from the first antenna 10 in the direction of the second antenna 20 is converted into current flowing to the ground at the first extension 34, and the energy radiated to the second antenna 20 is reduced. Electromagnetic energy radiated from the second antenna 20 toward the first antenna 10 is converted into current flowing to the ground at the second extension 35, so that the energy radiated to the first antenna 10 is reduced, the interference between the first antenna 10 and the second antenna 20 is reduced, and the current direction is shown by an arrow direction in fig. 5.
In some embodiments, the first extension 34 is longer than the first antenna 10 in the direction of the first connection 31 towards the first antenna 10 and the second extension 35 is longer than the second antenna 20 in the direction of the second connection 32 towards the second antenna 20. That is, the first extension 34 protrudes from the reference ground toward the antenna, or beyond the first antenna 10, and the second extension 35 protrudes from the second antenna 20, so that the energy radiated from the first antenna 10 to the second antenna 20, and the energy radiated from the second antenna 20 to the first antenna 10 can be further reduced, and the interference between the first antenna and the second antenna can be reduced.
In some embodiments, referring to fig. 3-5, a second spatial region 50 is spaced between the first extension 34 and the second extension 35. The second spatial region 50 functions substantially the same as the first spatial region 40 to prevent current from the first antenna 10 from flowing to the second antenna 20 or current from the second antenna 20 from flowing to the first antenna 10, reducing interference between the first antenna 10 and the second antenna 20.
In some embodiments, the first space region 40 and the second space region 50 are in communication, such that the first space region 40 and the second space region 50 form a completely communicating isolation region, preferably isolating the first antenna 10 and the second antenna 20, and preventing current flow between the first antenna 10 and the second antenna 20.
The first extension portion 34 and the second extension portion 35 may take any suitable shape, and since the first extension portion 34 functions to convert energy radiated from the first antenna 10 to the second antenna 20 into current and flow the current through the reference ground, and the second extension portion 35 functions to convert energy radiated from the second antenna 20 to the first antenna 10 into current and flow the current through the reference ground, the first extension portion 34 can better cover a portion of the first antenna 10 close to the second antenna 20, and the second extension portion 35 can better cover a portion of the second antenna 20 close to the first antenna 10.
For example, in the embodiment shown in fig. 6, the first extension portion 34 includes a first body portion 341 and a first bending portion 342, and the first body portion 341 and the first bending portion 342 are perpendicular. The second extension portion 35 includes a second body portion 351 and a second bending portion 352, and the second body portion 351 and the second bending portion 352 are perpendicular. The first extension 34 and the second extension 35 are generally L-shaped, so that the first extension 34 can well wrap the portion of the first antenna 10 near the second antenna 20, and the second extension 35 can well wrap the portion of the second antenna 20 near the first antenna 10. The radiation energy of the first antenna 10 to the second antenna 20 and the radiation energy of the second antenna 20 to the first antenna 10 can be reduced well, and the mutual interference of the first antenna 10 and the second antenna 20 can be reduced.
In other embodiments, the first body portion 341 and the first bending portion 342, and the second body portion 351 and the second bending portion 352 may be angled at other angles. For example, a first angle is formed between the first body portion 341 and the first bending portion 342, and a second angle is formed between the second body portion 351 and the second bending portion 352, where the first angle and the second angle are greater than 0 degrees and less than 180 degrees.
The first extension 34 and the second extension 35 may also have other shapes, such as an arc, etc., specifically, such as a 60-90 degree arc.
In some embodiments, the region where the first spatial region 40 and the second spatial region 50 communicate is perpendicular to the connection line of the first antenna 10 and the second antenna 20. The first spatial region 40 and the second spatial region 50 are in communication with each other to form a region having a substantially equal distance from the first antenna 10 and the second antenna 20, wherein the substantially equal distance may be equal or may differ by a small amount.
When the area where the first space area 40 and the second space area 50 are communicated is perpendicular to the connection line of the first antenna 10 and the second antenna 20 and the distances from the first antenna 10 and the second antenna 20 are approximately equal, the first antenna 10 and the second antenna 20 can obtain better isolation within the operation bandwidth.
The embodiment of the application also provides electronic equipment, which comprises the antenna assembly of any embodiment. The electronic device may be any device having a communication function, such as an interactive smart tablet, a large-screen smart display device, a tablet computer, a personal computer, a laptop, a smart phone, etc.
Fig. 7 shows simulation results of the antenna isolation, wherein a curve 102 is a simulation curve using the antenna assembly shown in fig. 3, and a curve 101 is a simulation curve not using the antenna assembly shown in fig. 3 (e.g., the antenna assembly does not include the first isolation region 40, the first extension portion 34, and the second extension portion), and an abscissa indicates the antenna position, and an ordinate indicates the isolation of the first antenna 10 and the second antenna 20. It can be seen that at the same antenna location (the same antenna location for points a and B), with the antenna assembly shown in fig. 3 comprising the first isolation region 40, the first extension 34 and the second extension, the isolation is reduced by 6.
With the antenna assembly of the embodiments of the present application including the first isolation region 40, the first extension portion 34, and the second extension portion, the performance of the antenna is improved without increasing the cost.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the utility model, the steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
