Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. The embodiments listed in this 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 application. 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 the like, which has the antenna module 10. Taking the electronic apparatus 100 as a mobile phone for example, for convenience of description, the width direction of the electronic apparatus 100 is defined as the X direction, the length direction of the electronic apparatus 100 is defined as the Y direction, and the thickness direction of the electronic apparatus 100 is defined as the Z direction, which are defined with reference to the first viewing angle of the electronic apparatus 100.

Referring to fig. 2, an antenna module 10 is provided in an embodiment of the present application. The antenna module 10 includes a signal source 1, a first radiator array 2, a second radiator array 3, and a switching 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 signal. 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 surfaces of the first radiator array 2 and the second radiator array 3 are coplanar, the switching circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate one beam together. Referring to fig. 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 radiator array 2 and the second radiator to radiate two beams with different directions, respectively.

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 can be understood that the first radiator array 2 is a plurality of radiators arranged in an array on a side wall of the electronic device 100. The beam scanning surface of the first radiator array 2 is a surface parallel to the side wall provided with the first radiator array 2. The beam scanning surface of the second radiator array 3 is a surface parallel to the side wall provided with the second radiator array 3. The beam scanning plane of the first radiator array 2 being coplanar with the beam scanning plane of the second radiator array 3 means that the side walls carrying the first radiator array 2 and the side walls carrying the second radiator array 3 are oriented the same and parallel or coplanar. The beam scanning plane of the first radiator array 2 being non-coplanar with the 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 intersect or are oppositely directed.

Referring to fig. 5, the directions of the sidewalls of the first radiator array 2 and the second radiator array 3 are reversed, so that the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar. Referring to fig. 4 and fig. 5 together, when the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar, the beam directions 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 respectively configured to receive the excitation signals of different signal sources 1, so that the first radiator array 2 and the second radiator array 3 do not need to operate simultaneously, and particularly, if the beam direction of the first radiator array 2 is the optimum direction of the signal and the direction of the second radiator array 3 is the poor direction of the signal, the first radiator array 2 can be controlled to operate and the second radiator array 3 does not operate, so as to reduce the power consumption of the antenna module 10 and save 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 that the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are coplanar. Referring to fig. 3 and fig. 6, 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 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 radiator arrays 1*4 (1 column and 4 rows), and the combined radiator array 5 is a 1*8 (1 column and 8 rows) radiator array or a 2×4 (2 columns and 4 rows) radiator array. Compared with the first radiator array 2 and the second radiator array 3 which are independent of each other, the coverage range 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.

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 according to the relative position relation 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 an excitation signal of a signal source 1 so that the first radiator array 2 and the second radiator array 3 are combined to form a combined radiator array 5, so that the coverage range of a beam is wider, the antenna gain is stronger, and 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 respectively receive the excitation signals of different signal sources 1, and only the radiator arrays with better signals are controlled to work, so that the first radiator array 2 and the second radiator array 3 do not need to work at the same time, the power consumption of the antenna module 10 is reduced, and the electric energy is saved.

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

It will be appreciated 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 the radiator is a transmitting end or a receiving end of an antenna signal. The type of radiator may be a patch antenna, a micro-slot antenna, or the like, and is not limited in this application. The radiators can be dual polarized antennas so as to form a space Multiple-Input Multiple-Output antenna (MIMO) and a polarized Multiple-Input Multiple-Output antenna (MIMO), so that signals are Output and received through the Multiple radiators, thereby improving communication quality; space resources can be fully utilized, multiple transmission and multiple reception can be realized through the antenna module 10, and the system channel capacity can be doubled under the condition of not increasing frequency spectrum resources and antenna transmitting power.

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 switching circuit 4. The first radiator array 2 and the second radiator array 3 are electrically connected to the other end of the switching 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.

In particular, the first signal source 11 and the second signal source 12 may each generate an excitation signal 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 second signal source 12 can be turned off if the signal transmission quality of the beam direction of the first radiator array 2 is poor, thereby reducing the power consumption of the antenna module 10 and improving the efficiency of the antenna module 10.

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 switch circuit 4 controls the first signal source 11 or the second signal source 12 to be turned on 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 transmit and receive antenna signals under the excitation signal of one of the signal sources 1, so that the first radiator array 2 and the second radiator array 3 radiate the same beam.

Specifically, referring to fig. 3 and fig. 6 together, 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 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 range 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 switching 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. The other end of the first switch 41 is electrically connected to one end of the third switch 43 and the first radiator array 2. One end of the second switch 42 is electrically connected to the second signal source 12. The other end of the second switch 42 is electrically connected to the other end of the third switch 43 and the second radiator array 3.

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 surfaces 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 controls 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 fig. 6 together, 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 turned on, the first switch 41 to be turned off, and the second switch 42 to be turned on, 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, and the antenna gain is stronger, so that 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.

It will be appreciated that the structure of the first leg 51 is the same or similar to the structure of the second leg 52. The first branch 51 provided in the embodiment of the present application includes, but is not limited to, the following embodiments.

In one possible implementation, referring to fig. 8, the first signal source 11 is configured to generate a first intermediate frequency signal. The first branch 51 includes a first local oscillator signal source 511 and a first mixer 512. The first local oscillation signal source 511 is electrically connected to one end of the first mixer 512. One end of the first mixer 512 is also electrically connected to one end of the third switch 43. The other end of the first mixer 512 is electrically connected to the first radiator array 2. The first local oscillation signal source 511 is configured to generate a first local oscillation signal.

One end of the fourth switch 515 is electrically connected to the other end of the first receiving channel 513 or the other end of the first transmitting channel 514, and the other end of the fourth switch 515 is electrically connected to the first radiator array 2. When the fourth switch 515 turns on the first radiator array 2 and the first receiving channel 513, the first radiator array 2 is in a receiving antenna signal state. When the fourth switch 515 turns on the first radiator array 2 and the first transmission channel 514, the first radiator array 2 is in a transmission antenna signal state.

Further, referring to fig. 8, the first radiator array 2 includes a plurality of first radiators 21 arranged in an array. The first branch 51 further comprises a plurality of branches. Each of the branches is electrically connected between the other end of the fourth switch 515 and one of the first radiators 21. Each of the branches includes a phase shifter 516, a power amplifier 517, a low noise amplifier 518, and a fifth switch 519. One end of the phase shifter 516 is electrically connected to the other end of the fourth switch 515. The other end of the phase shifter 516 is electrically connected to one end of the power amplifier 517 and one end of the low noise amplifier 518. One end of the fifth switch 519 is electrically connected to the other end of the power amplifier 517 or the other end of the low noise amplifier 518. The other end of the fifth switch 519 is electrically connected to the first radiator 21. When the fourth switch 515 turns on the first radiator array 2 and the first receiving channel 513, one end of the fifth switch 519 is electrically connected to the other end of the low noise amplifier 518, so that the first radiator 21 electrically connected to the branch circuit is a receiving end of the antenna signal. When the fourth switch 515 turns on the first radiator array 2 and the first radiating channel 514, one end of the fifth switch 519 is electrically connected to the other end of the power amplifier 517, so that the first radiator 21 electrically connected to the branch circuit is a transmitting end of an antenna signal.

The first radiator array 2 is made to form a multiple-in multiple-out mode by setting each of the branches to have a mode of receiving and transmitting signals. For example, if the first radiator array 2 includes the radiator array 1*4, the first radiator array 2 can form a multi-channel and multiple-input multiple-output antenna 4*4, so that space resources can be fully utilized, multiple-input multiple-output can be realized through the antenna module 10, and the system channel capacity can be doubled without increasing frequency spectrum resources and antenna transmitting power.

An electronic device 100 according to an embodiment of the present application, where the electronic device 100 includes an antenna module 10 according to any one of the above embodiments.

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 arranged on the first side wall 101 and the second side wall 102. The first side wall 101 and the second side wall 102 are relatively movable to be parallel or coplanar to make beam scanning surfaces of the first radiator array 2 and the second radiator array 3 coplanar. Alternatively, the first side wall 101 and the second side wall 102 can be relatively moved to intersect so that the beam scanning surfaces of the first radiator array 2 and the second radiator array 3 are not coplanar.

Specifically, the first side wall 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 side wall 101 is an inner surface of the housing of the electronic device 100, the first radiator array 2 is disposed on the first side wall 101, including but not limited to, the first radiator array 2 is formed on the first side wall 101, or a substrate provided with the first radiator array 2 is fixed on the first side wall 101, or the first radiator array 2 is fixed in the electronic device 100 by other supports, such that the first radiator array 2 is opposite to the first side wall 101.

Specific structures of the electronic device 100 include, but are 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 application. 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 the folded state, the switching circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate one beam in common. When the electronic device 100 is in the unfolded state, the switching circuit 4 controls the first radiator array 2 and the second radiator array 3 to radiate two beams having different directions, respectively. It can be understood that the folding state is that the folding angle between the folding screens at the two sides of the electronic device 100 is 0 ° to 5 ° or 355 ° to 360 °, including 5 ° and 355 °. The unfolded state is that the bending angle between the folding screens at the two sides of the electronic device 100 is 5-355 °, wherein 5 ° and 355 ° are not included.

Specifically, taking a foldable device as an example of a foldable mobile phone, referring to fig. 5, the first side wall 101 and the second side wall 102 are two side walls located at 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 the folded state, the first side wall 101 and the second side wall 102 are close to each other until the first side wall 101 and the second side wall 102 are parallel or coplanar.

The rotation axis L1 is described as extending in the Y-axis direction. The first sidewall 101 and the second sidewall 102 being parallel means that the first sidewall 101 and the second sidewall 102 are parallel in the X-axis direction, or that the first sidewall 101 is flush with the second sidewall 102 in the X-axis direction, or that the first sidewall 101 is aligned with the second sidewall 102 in the X-axis direction.

In one possible implementation, 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 comprises m rows and N columns of second radiators. The axial direction of the rotation axis L1 is the column 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 of (m+m) rows and N columns. Wherein M, N, M are positive integers. M and M may be equal or different. In fig. 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 beam coverage in the Z-axis direction, so as to improve the antenna gain.

In another possible embodiment, referring to fig. 9 to 11, the first radiator array 2 and the second radiator array 3 are disposed 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 in the Y-axis direction. Further, the preset interval may be an interval 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 comprises M rows and n columns of second radiators. The axial direction of the rotation axis L1 is the column 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 of M rows (n+n) columns. Wherein M, N, N are positive integers. N and N may be equal or unequal. In fig. 9 to 11, M is 4, 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 have a partial overlap in the Y-axis direction.
