Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The embodiments listed in the present application may be appropriately combined with each other.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 100 may be a phone, a television, a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, a base station, or other devices having the antenna module 10. Taking the electronic device 100 as a mobile phone as an example, for convenience of description, the electronic device 100 is defined with reference to the first viewing angle, the width direction of the electronic device 100 is defined as the X direction, the length direction of the electronic device 100 is defined as the Y direction, and the thickness direction of the electronic device 100 is defined as the Z direction.

Referring to fig. 2, an antenna module 10 according to an embodiment of the present disclosure is provided. The antenna module 10 includes a signal source 1, a first radiator array 2, a second radiator array 3, and a switch circuit 4. The signal source 1 is used for generating an excitation signal. The first radiator array 2 and the second radiator array 3 are both used for receiving and transmitting antenna signals under the excitation of the excitation signals. The switch circuit 4 is electrically connected between the signal source 1 and the first radiator array 2 and the second radiator array 3. Referring to fig. 3, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar, the switch circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate a beam together. Referring to fig. 4, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are not coplanar, the switch circuit 4 controls the first radiator array 2 and the second radiator array to respectively radiate two beams in different directions.

It is understood that the antenna module 10 may be an antenna structure that radiates millimeter wave signals, sub-millimeter wave signals, or terahertz wave signals.

It is understood that the first radiator array 2 is a plurality of radiators arranged in an array on a sidewall of the electronic device 100. The beam scanning surface of the first radiator array 2 is a surface parallel to the side wall on which the first radiator array 2 is disposed. The beam scanning surface of the second radiator array 3 is a surface parallel to the side wall on which the second radiator array 3 is provided. The coplanar beam scanning plane of the first radiator array 2 and the coplanar beam scanning plane of the second radiator array 3 means that the side wall carrying the first radiator array 2 and the side wall carrying the second radiator array 3 are in the same orientation and are parallel or coplanar. The fact that the beam scanning plane of the first radiator array 2 is not coplanar with the beam scanning plane of the second radiator array 3 means that the side wall carrying the first radiator array 2 intersects with or faces opposite to the side wall carrying the second radiator array 3.

Referring to fig. 5, the side walls of the first radiator array 2 and the second radiator array 3 face in opposite directions, so that the beam scanning planes of the first radiator array 2 and the second radiator array 3 are not coplanar. Referring to fig. 4 and 5, when the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar, the beam orientations of the first radiator array 2 and the second radiator array 3 are different, and the first radiator array 2 and the second radiator array 3 are set to receive excitation signals of different signal sources 1, respectively, so that the first radiator array 2 and the second radiator array 3 do not need to work simultaneously, and particularly, if the beam orientation of the first radiator array 2 is the direction with the optimal signal and the orientation of the second radiator array 3 is the direction with the poor signal, the first radiator array 2 can be controlled to work and the second radiator array 3 does not work, so as to reduce the power consumption of the antenna module 10 and save the electric energy.

Referring to fig. 6, the sidewalls of the first radiator array 2 and the second radiator array 3 are oriented in the same direction and are coplanar, so the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar. Referring to fig. 3 and 6, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar, the first radiator array 2 and the second radiator array 3 receive an excitation signal of a signal source 1, and the first radiator array 2 and the second radiator array 3 are combined to form a new radiator array, which is referred to as a combined radiator array in this application. Referring to fig. 7, for example, the first radiator array 2 and the second radiator array 3 are both 1 × 4(1 row and 4 columns) radiator arrays, and the combined radiator array 5 is 1 × 8(1 column and 8 rows) radiator array or 2 × 4(2 columns and 4 rows) radiator arrays. Compared with the first radiator array 2 and the second radiator array 3 which are independent of each other, the coverage of the beam generated by the combined radiator array 5 is wider, the antenna gain is stronger, and thus the antenna module 10 has higher signal transmission quality and data transmission rate.

By arranging the switch circuit 4 in the antenna module 10, the switch circuit 4 can switch the radiation modes received by the first radiator array 2 and the second radiator array 3 according to the relative position relationship of the beam scanning surfaces of the first radiator array 2 and the second radiator array 3, and when the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are coplanar, the first radiator array 2 and the second radiator array 3 are controlled to receive the excitation signal of one signal source 1, so that the first radiator array 2 and the second radiator array 3 are combined to form one combined radiator array 5, thereby widening the coverage range of the beam, and enhancing the antenna gain, so that the antenna module 10 has higher signal transmission quality and data transmission rate; when the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar, the first radiator array 2 and the second radiator array 3 are controlled to receive excitation signals of different signal sources 1 respectively, only the radiator array with a better signal is controlled to work, and the first radiator array 2 and the second radiator array 3 do not need to work at the same time, so that the power consumption of the antenna module 10 is reduced, and the electric energy is saved.

It can be understood that the signal source 1 may be a chip or a module generating an intermediate frequency signal; the signal source 1 may also be a chip or a module generating a radio frequency signal.

It is understood that the first radiator array 2 and the second radiator array 3 are one-dimensional radiators arranged in a straight line, two-dimensional radiators arranged in a matrix, or three-dimensional radiators. The radiator is made of conductive materials and is a transmitting end or a receiving end of an antenna signal. The type of the radiator may be a patch antenna, a micro slot antenna, etc., and the type of the radiator is not limited in this application. The radiator may be a dual polarization antenna so as to form a spatial Multiple-Input Multiple-Output (MIMO) antenna and a polarization Multiple-Input Multiple-Output (MIMO) antenna, so that signals are Output and received through the plurality of radiators, thereby improving communication quality; space resources can be fully utilized, multiple transmission and multiple reception are realized through the antenna module 10, and the system channel capacity can be improved in multiples under the condition that frequency spectrum resources and antenna transmitting power are not increased.

Referring to fig. 2, the signal source 1 includes a first signal source 11 and a second signal source 12. The first signal source 11 and the second signal source 12 are electrically connected to one end of the switch circuit 4. The first radiator array 2 and the second radiator array 3 are electrically connected to the other end of the switch circuit 4. When the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar, the switch circuit 4 controls the first signal source 11 to be conducted with the first radiator array 2, and controls the second signal source 12 to be conducted with the second radiator array 3, so that the first radiator array 2 receives and transmits antenna signals under the excitation signal of the first signal source 11, and the second radiator array 3 receives and transmits antenna signals under the excitation signal of the second signal source 12.

Specifically, the first signal source 11 and the second signal source 12 may generate the excitation signals respectively in different time periods. In other words, the transceiving antenna signals of the first radiator array 2 and the second radiator array 3 may not be synchronized. When the beam direction of the first radiator array 2 is the optimal signal transmission direction, the first signal source 11 is controlled to generate an excitation signal for the first radiator array 2, so that the first radiator array 2 receives and transmits the antenna signal, and the signal transmission quality pointed by the beam of the first radiator array 2 is poor, the second signal source 12 can be turned off, so that the power consumption of the antenna module 10 is reduced, and the efficiency of the antenna module 10 is improved.

Referring to fig. 3 and 6, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar, the switch circuit 4 controls the first signal source 11 or the second signal source 12 to be conducted with the first radiator array 2 and the second radiator array 3, so that the first radiator array 2 and the second radiator array 3 receive and transmit antenna signals under an excitation signal of the signal source 1, and the first radiator array 2 and the second radiator array 3 radiate the same beam.

Specifically, referring to fig. 3 and fig. 6, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar, the first radiator array 2 and the second radiator array 3 receive the excitation signal of the first signal source 11 or the second signal source 12, and the first radiator array 2 and the second radiator array 3 are combined to form a combined radiator array 5. In other words, the first radiator array 2 and the second radiator array 3 receive or transmit signals simultaneously. The coverage of the beam generated by the combined radiator array 5 is wider, and the antenna gain is stronger, so that the antenna module 10 has higher signal transmission quality and data transmission rate.

In one possible implementation, referring to fig. 2, the switch circuit 4 includes a first switch 41, a second switch 42 and a third switch 43. One end of the first switch 41 is electrically connected to the first signal source 11.

Further, the antenna module 10 further includes a controller (not shown). The controller is electrically connected to the switching circuit 4. Referring to fig. 4 and 5, when the beam scanning planes of the first radiator array 2 and the second radiator array 3 are not coplanar, the controller controls the third switch 43 to be opened and the first switch 41 and the second switch 42 to be closed. When the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are coplanar, the controller controls the third switch 43 to be closed, the first switch 41 to be closed and the second switch 42 to be opened, so that the first radiator array 2 and the second radiator array 3 both receive the excitation signal of the first signal source 11, and further the first radiator array 2 and the second radiator array 3 form the combined radiator array 5, so that the coverage range of the beam generated by the combined radiator array 5 is wider, the antenna gain is stronger, and the antenna module 10 has higher signal transmission quality and data transmission rate.

Referring to fig. 3 and 6, when the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are coplanar, the controller controls the third switch 43 to be closed, the first switch 41 to be opened, and the second switch 42 to be closed, so that the first radiator array 2 and the second radiator array 3 both receive the excitation signal of the second signal source 12, and further the first radiator array 2 and the second radiator array 3 form the combined radiator array 5, so that the coverage range of the beam generated by the combined radiator array 5 is wider, the antenna gain is stronger, and the antenna module 10 has higher signal transmission quality and data transmission rate.

Referring to fig. 8, the antenna module 10 includes a first branch 51 and a second branch 52. The first branch 51 is electrically connected to one end of the third switch 43 and the first radiator array 2. The second branch 52 is electrically connected to the other end of the third switch 43 and the second radiator array 3.

In an embodiment of the present application, an electronic device 100 is provided, where the electronic device 100 includes any one of the antenna modules 10.

Referring to fig. 5, the electronic device 100 includes a first sidewall 101 and a second sidewall 102. The first radiator array 2 and the second radiator array 3 are respectively disposed on the first sidewall 101 and the second sidewall 102. The first side wall 101 and the second side wall 102 can move relatively to be parallel or coplanar, so that the beam scanning planes of the first radiator array 2 and the second radiator array 3 are coplanar. Or, the first sidewall 101 and the second sidewall 102 can move relatively to intersect, so that the beam scanning planes of the first radiator array 2 and the second radiator array 3 are not coplanar.

Specifically, the first sidewall 101 may be an inner surface of a housing of the electronic device 100, or a surface of a carrier for carrying the first radiator array 2 in the electronic device 100. When the first sidewall 101 is an inner surface of the housing of the electronic device 100, the first radiator array 2 is disposed on the first sidewall 101, including but not limited to, the first radiator array 2 is formed on the first sidewall 101, or a substrate on which the first radiator array 2 is disposed is fixed on the first sidewall 101, or the first radiator array 2 is fixed in the electronic device 100 through another support, and the first radiator array 2 is opposite to the first sidewall 101.

The specific structure of the electronic device 100 includes, but is not limited to, the following embodiments.

Referring to fig. 5 and fig. 6, fig. 5 is an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 is a foldable device having a rotation axis L1. The first side wall 101 and the second side wall 102 are two side walls of the electronic device 100 located on two opposite sides of the rotation axis L1. When the electronic device 100 is in a folded state, the switch circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate a beam together. When the electronic device 100 is in the unfolded state, the switch circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate two beams in different directions respectively. It can be understood that the folding state is a folding angle between the two side folding screens of the electronic device 100 being 0 ° to 5 ° or 355 ° to 360 °, including 5 ° and 355 °. The folded state is that the folding angle between the two side folding screens of the electronic device 100 is 5 ° to 355 °, wherein 5 ° and 355 ° are excluded.

Specifically, taking the foldable device as a foldable mobile phone for example, referring to fig. 5, the first side wall 101 and the second side wall 102 are two side walls located at two opposite sides of the rotation axis L1 when the electronic device 100 is unfolded. Referring to fig. 6, when the electronic device 100 is in a folded state, the first sidewall 101 and the second sidewall 102 are close to each other until the first sidewall 101 and the second sidewall 102 are parallel or coplanar.

The description will be given taking an example in which the rotation shaft L1 extends in the Y-axis direction. The first sidewall 101 and the second sidewall 102 are parallel, that is, the first sidewall 101 and the second sidewall 102 are parallel in the X-axis direction, or the first sidewall 101 and the second sidewall 102 are flush in the X-axis direction, or the first sidewall 101 and the second sidewall 102 are aligned in the X-axis direction.

In one possible implementation manner, referring to fig. 5 to 7, when the electronic device 100 is in the unfolded state, the first radiator array 2 and the second radiator array 3 are symmetrically disposed about the rotation axis L1.

Specifically, referring to fig. 5 to 7, the first radiator array 2 includes M rows and N columns of first radiators 21. The second radiator array 3 includes m rows and N columns of second radiators. The axial direction of the rotation axis L1 is the row arrangement direction of the first radiator array 2 and the second radiator array 3. When the electronic device 100 is in a folded state, the first radiator array 2 and the second radiator array 3 are combined to form a radiator array in (M + M) rows and N columns. Wherein M, N and M are positive integers. M and M may be equal or different. In FIGS. 5 to 7, M and M are both 4, and N is 1.

In this embodiment, when the electronic device 100 is folded, the first radiator array 2 and the second radiator array 3 are combined into one combined radiator array 5 in the Z-axis direction, and the combined radiator array 5 can effectively increase the coverage of the beam in the Z-axis direction, thereby improving the antenna gain.

In another possible implementation manner, referring to fig. 9 to 11, the first radiator array 2 and the second radiator array 3 are arranged in a staggered manner in the axial direction of the rotation axis L1. In other words, the first radiator array 2 and the second radiator array 3 have a predetermined pitch along the Y-axis direction. Further, the preset distance may be a distance between two adjacent first radiators 21.

Specifically, referring to fig. 9 to 11, the first radiator array 2 includes M rows and N columns of first radiators 21. The second radiator array 3 includes M rows and n columns of second radiators. The axial direction of the rotation axis L1 is the row arrangement direction of the first radiator array 2 and the second radiator array 3. When the electronic device 100 is in a folded state, the first radiator array 2 and the second radiator array 3 are combined to form radiator arrays of M rows (N + N) columns. Wherein M, N and N are positive integers. N and N may be equal or different. In FIGS. 9 to 11, M is 4, and N and N are both 1.

Of course, in other embodiments, when the electronic device 100 is folded, the first radiator array 2 and the second radiator array 3 may partially overlap in the Y-axis direction.
