wherein the first state is one of a closed state and an open state, and the second state is the other of the closed state and the open state.
Optionally, the first direction and the second direction in the embodiment of the present application are mutually orthogonal.
It should be noted that, the working modes of the two groups of millimeter wave antenna arrays are controlled in different states of the electronic device, so that the multidimensional beam scanning of the electronic device is realized.
Specifically, as further shown in fig. 2, in order to control the operation of two sets of millimeter wave antenna arrays, the electronic device according to the embodiment of the present application further includes:
a signal converter 300;
and a signal processing circuit (not shown in the figure) connected to the signal converter 300, the first millimeter-wave antenna array 110, and the second millimeter-wave antenna array 120, respectively, and configured to send the signal generated by the signal converter 300 to the first millimeter-wave antenna array 110 and/or the second millimeter-wave antenna array 120.
It should be noted that, the purpose of the present application is to design multiple groups of millimeter wave array antennas on a folding electronic device in order to solve the limitation of the beam scanning range of the millimeter wave array antennas in the existing electronic device, and control the flow direction of signals through a signal processing circuit, thereby realizing beam scanning with more dimensions, and effectively improving the quality of millimeter wave communication and user experience.
Alternatively, the signal converter 300 may be an intermediate frequency signal converter for generating an intermediate frequency signal.
As further shown in fig. 2, the signal processing circuit includes:
a first rf module 510 connected to the first set of mmwave antenna arrays 110;
a second rf module 520 connected to the second set of mm-wave antenna arrays 120;

It should be noted that the circuit architecture shown in fig. 2 in this application is described by taking a single-polarized antenna element as an example, but the polarization form of the antenna element in this application may include single polarization, orthogonal dual polarization, or circular polarization. The antenna unit in the present application may be a square microstrip antenna as shown in the figure, or may be a circular microstrip antenna or other antenna forms with similar antenna characteristics.
The millimeter wave antenna array scanning device comprises a first group of millimeter wave antenna arrays 110 and a second group of millimeter wave antenna arrays 120, and when an independent group of millimeter wave antenna arrays can perform two-dimensional scanning, a new millimeter wave antenna array formed by two independent groups of millimeter wave antenna arrays can obtain a wider scanning angle.
In the embodiment of the present application, the switch is mainly controlled by the folding state (including the closing state and the unfolding state) of the electronic device to achieve the purpose of multi-dimensional beam scanning, and first, the arrangement manner of the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 in the electronic device in the present application is described as follows.
First group's millimeter wave antenna array and second group millimeter wave antenna array in this application adopt for the mode of pivot symmetry setting, when specifically setting up, include again: the antenna radiation direction is parallel to the display screen of the electronic device and the antenna radiation direction is perpendicular to the display screen of the electronic device, and the two setting modes are respectively explained as follows.
In the first mode, the radiation direction of the antenna is parallel to the display screen of the electronic device.
Situation one,
As shown in fig. 1 and fig. 3 to fig. 5, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays in this case are arranged as follows:
the antenna elements of the first group of millimeter wave antenna arrays 110 are located in a first frame region on one side of the first screen 11 parallel to the rotation axis, and the antenna elements of the second group of millimeter wave antenna arrays 120 are located in a first frame region on one side of the second screen 12 parallel to the rotation axis;
wherein the first bezel area includes: the frame or the inside of the electronic equipment opposite to the frame.
It should be noted that, in this case, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrically disposed with respect to the rotation axis, that is, when the electronic device is in the closed state, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrical with respect to the middle seam formed after the electronic device is folded, and specifically, after the electronic device is closed, the display screen of the electronic device is still on the outer surface of the electronic device.
Specifically, when the electronic device is in a closed state as shown in fig. 1 and fig. 3, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 may jointly form a target millimeter wave antenna array 130, a signal generated by the signal converter 300 may selectively enter the synchronous controller 200, after power distribution, simultaneously enter the first radio frequency module 510 and the second radio frequency module 520, and after synchronous modulation processing under the control of the synchronous controller 200, enter the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120, so that the two arrays are synchronously transmitted as the target millimeter wave antenna array 130, and at this time, scanning of the millimeter wave antennas in two different directions, that is, scanning in a direction parallel to the antenna arrays (i.e., in the θ direction) and in a direction perpendicular to the antenna arrays (i.e., in the Φ; the signal generated by the signal converter 300 may also enter the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, and is transmitted through the corresponding first group of millimeter wave antenna arrays 110 or the second group of millimeter wave antenna arrays 120 after being modulated by the radio frequency circuit, at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, the θ direction), can be realized; further, reception is the reverse of the above-described transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 4 and 5, the signal generated by the signal converter 300 is selected by the switch 400 to enter the first radio frequency module 510 or the second radio frequency module 520, and is modulated by the radio frequency circuit and transmitted through the corresponding first millimeter wave antenna array 110 or the second millimeter wave antenna array 120, at this time, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 work independently, and the millimeter wave antenna can be scanned in one direction, that is, in a direction parallel to the antenna arrays (i.e., the θ direction); further, reception is the reverse of the above-described transmission.
In this case, when the electronic device is in a closed state, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 may work independently, and may also form a target millimeter wave antenna array together, so as to implement multidimensional scanning in two angular directions of θ and Φ; when the electronic device is in the unfolded state, the first group 110 and the second group 120 of millimeter-wave antenna arrays respectively scan along the θ direction.
The second case,
As shown in fig. 6 to 9, the arrangement of the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays in this case is as follows:
the antenna elements of the first group of millimeter wave antenna arrays 110 are located in a second frame region on one side of the first screen 11 perpendicular to the rotation axis, and the antenna elements of the second group of millimeter wave antenna arrays 120 are located in a second frame region on one side of the second screen 12 perpendicular to the rotation axis;
wherein the second bezel region includes: the frame of the first end, the inside of the electronic equipment opposite to the frame of the first end, the frame of the second end or the inside of the electronic equipment opposite to the frame of the second end;
the first end and the second end are opposite ends of the electronic device.
At this time, the distances between the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 and the rotation axis are both greater than or equal to a first setting value, that is, after the electronic device is unfolded, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 are not enough to form a target millimeter wave antenna array.
It should be noted that, in this case, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrically disposed with respect to the rotation axis, that is, when the electronic device is in the closed state, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrical with respect to the middle seam formed after the electronic device is folded, and specifically, after the electronic device is closed, the display screen of the electronic device is still on the outer surface of the electronic device.
Specifically, when the electronic device is in a closed state as shown in fig. 6 and 7, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 may jointly form a target millimeter wave antenna array 130, a signal generated by the signal converter 300 may selectively enter the synchronous controller 200, and after power distribution, the signal simultaneously enters the first radio frequency module 510 and the second radio frequency module 520, and after synchronous modulation processing under the control of the synchronous controller 200, the signal enters the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120, so that the two arrays are transmitted synchronously as the target millimeter wave antenna array 130, and at this time, scanning of the millimeter wave antennas in two different directions, that is, scanning in a direction parallel to the antenna arrays (i.e., in the θ direction) and in a direction perpendicular to the antenna arrays (i.e.; the signal generated by the signal converter 300 may also enter the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, and is transmitted through the corresponding first group of millimeter wave antenna arrays 110 or the second group of millimeter wave antenna arrays 120 after being modulated by the radio frequency circuit, at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, the θ direction), can be realized; further, reception is the reverse of the above-described transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 8 and 9, the signal generated by the signal converter 300 selectively enters the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, is modulated by the radio frequency circuit, and is transmitted through the corresponding first group of millimeter wave antenna arrays 110 or the second group of millimeter wave antenna arrays 120, and at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, the θ direction) can be achieved; further, reception is the reverse of the above-described transmission.
In this case, when the electronic device is in a closed state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays can work independently and can also form a target millimeter wave antenna array together, so as to implement multidimensional scanning in two angular directions of θ and φ; when the electronic device is in the unfolded state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays respectively scan along the theta direction.
Case three,
As shown in fig. 10 to 13, the arrangement of the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays in this case is as follows:
the antenna elements of the first group of millimeter wave antenna arrays 110 are located in a second frame region on one side of the first screen 11 perpendicular to the rotation axis, and the antenna elements of the second group of millimeter wave antenna arrays 120 are located in a second frame region on one side of the second screen 12 perpendicular to the rotation axis;
wherein the second bezel region includes: the frame of the first end, the inside of the electronic equipment opposite to the frame of the first end, the frame of the second end or the inside of the electronic equipment opposite to the frame of the second end;
the first end and the second end are opposite ends of the electronic device.
At this time, the distances between the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays and the rotating shaft are both smaller than or equal to a second set value, that is, after the electronic device is unfolded, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 can also form the target millimeter wave antenna array 130.
It should be noted that, in this case, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrically disposed with respect to the rotation axis, that is, when the electronic device is in the closed state, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are symmetrical with respect to the middle seam formed after the electronic device is folded, and specifically, after the electronic device is closed, the display screen of the electronic device is still on the outer surface of the electronic device.
Specifically, when the electronic device is in a closed state as shown in fig. 10 and 11, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 jointly form the target millimeter wave antenna array 130, the signal generated by the signal converter 300 selectively enters the first radio frequency module 510 or the second radio frequency module 520 or the synchronous controller 200 through the switch 400, and when the signal enters the first radio frequency module 510 or the second radio frequency module 520, the signal is modulated by the radio frequency circuit and then transmitted through the corresponding first group of millimeter wave antenna arrays 110 or the corresponding second group of millimeter wave antenna arrays 120, at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (i.e., the θ direction) can be achieved; when a signal enters the synchronous controller 200, the signal enters the first radio frequency module 510 and the second radio frequency module 520 after power distribution, enters the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 after synchronous modulation processing under the control of the synchronous controller 200, so that the two arrays are used as target millimeter wave antenna arrays for synchronous transmission, and at the moment, the millimeter wave antenna can be scanned in two different directions, namely in a direction parallel to the antenna arrays (namely, in a theta direction) and in a direction perpendicular to the antenna arrays (namely, in a phi direction); further, reception is the reverse of the above-described transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 12 and 13, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 together form a large target millimeter wave antenna array 130, the circuit logic in this case is the same as that in the closed state of the electronic device, and the difference is that the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 synchronously transmit as the target millimeter wave antenna array 130 when operating synchronously, at this time, scanning of the millimeter wave antennas in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, in the θ direction), can be achieved, and in this case, double antenna gain and a wider scanning angle can be obtained; further, reception is the reverse of the above-described transmission.
In this case, when the electronic device is in the unfolded state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays can work independently and can also form a target millimeter wave antenna array together, so as to implement multidimensional scanning in two angular directions of θ and φ; when the electronic device is in a closed state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays can work independently and can also form a target millimeter wave antenna array together, so that double antenna gain and a wider scanning angle can be obtained.
Second mode, the antenna radiation direction is perpendicular to the display screen of the electronic device
As shown in fig. 14 and 17, the arrangement of the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays in this way is as follows:
the antenna units of the first group of millimeter wave antenna arrays 110 are located in a back cover area of one side of the first screen 11, which faces away from the display screen, and the distance between the first group of millimeter wave antenna arrays 110 and the rotating shaft is parallel to the rotating shaft and is less than or equal to a preset value; the antenna units of the second group of millimeter wave antenna arrays 120 are located in a back cover area of one side of the second screen 12, which faces away from the display screen, and the distance between the second group of millimeter wave antenna arrays 120 and the rotating shaft is parallel to the rotating shaft and is less than or equal to a preset value;
wherein the back cover region comprises: the back cover or the inside of the electronic device facing the back cover.
It should be noted that, in this case, the first millimeter-wave antenna array 110 and the second millimeter-wave antenna array 120 are symmetrically disposed with respect to the rotation axis, that is, when the electronic device is in the closed state, the first millimeter-wave antenna array 110 and the second millimeter-wave antenna array 120 are symmetrical with respect to the middle seam formed after the electronic device is folded.
Specifically, when the electronic device is in the closed state as shown in fig. 14 and 15, the signal generated by the signal converter 300 selectively enters the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, is modulated by the radio frequency circuit, and is transmitted through the corresponding first group of millimeter wave antenna arrays 110 or the corresponding second group of millimeter wave antenna arrays 120, and at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, the θ direction) can be achieved; further, reception is the reverse of the above-described transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 16 and 17, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 together form a target millimeter wave antenna array 130, a signal generated by the signal converter 300 may enter the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, and enter the first millimeter wave antenna array 110 or the second millimeter wave antenna array 120 after being synchronously modulated under the control of the synchronous controller 200, and at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in a direction parallel to the antenna arrays (that is, in the θ direction) can be achieved; the signal generated by the signal converter 300 may also selectively enter the synchronous controller 200, enter the first radio frequency module 510 and the second radio frequency module 520 after power distribution, enter the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 after synchronous modulation processing under the control of the synchronous controller 200, so that the two arrays are transmitted synchronously as the target millimeter wave antenna array 130, and at this time, scanning of the millimeter wave antenna in two different directions, namely, scanning in a direction parallel to the antenna arrays (i.e., the theta direction) and in a direction perpendicular to the antenna arrays (i.e., the phi direction), can be realized; further, reception is the reverse of the above-described transmission.
In this way, when the electronic device is in the unfolded state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays can work independently and can also form a target millimeter wave antenna array together, so that multidimensional scanning in two angular directions of theta and phi is realized; when the electronic equipment is in a closed state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays respectively and independently work to realize scanning along the theta direction.
It should be noted that the embodiments in this application may be used in combination, for example, when the first case and the second case are used simultaneously, when the electronic device is in the closed state, the two sets of millimeter wave antenna arrays on the side frames may implement multidimensional scanning of the θ angle and the Φ angle facing the outer side frame; when the folding electronic equipment is in an unfolding state, the two groups of millimeter wave antenna arrays positioned on the back of the two sectors of the electronic equipment can realize multidimensional scanning of an angle theta and an angle phi facing the back of the electronic equipment.
In the application, when two groups of millimeter wave antenna arrays work in a combined manner, the two groups of millimeter wave antenna arrays can scan in two mutually orthogonal angle directions, such as the theta angle and the phi angle, and scanning in angle directions other than the two angle directions is not excluded.
According to the embodiment of the application, multi-dimensional beam scanning of the electronic equipment can be achieved, and the quality of millimeter wave communication and user experience are effectively improved.

For example, in the case of the third mode in the first embodiment, in this case, the first state may be a closed state or an expanded state, and in this state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays may form a large antenna array to jointly transmit signals, and meanwhile, the electronic device may further select to transmit signals by using only one group of millimeter wave antenna arrays.
