The antenna unit in the application can be a square microstrip antenna as shown in the drawing, or a circular microstrip antenna or other antenna forms with similar antenna characteristics.
The present application includes the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120, and when the independent millimeter wave antenna arrays can perform two-dimensional scanning, a wider scanning angle can be obtained by the new millimeter wave antenna array formed by the two independent millimeter wave antenna arrays.
The embodiment of the present application mainly performs switch control through the folding state (including the closing state and the unfolding state) of the electronic device, so as to achieve the purpose of multi-dimensional beam scanning, and first, the arrangement mode of the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 in the electronic device is described as follows.
The first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays in the application are symmetrically arranged relative to the rotating shaft, and when the antenna arrays are specifically arranged, the antenna arrays comprise: 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 these two arrangements are described below.
In the first mode, the radiation direction of the antenna is parallel to the display screen of the electronic device.
In the first case,
As shown in fig. 1, 3 to 5, the arrangement of the first group millimeter wave antenna array and the second group millimeter wave antenna array in this case is:
the antenna units of the first millimeter wave antenna array 110 are located in a first frame area on one side of the first screen 11 parallel to the rotation axis, and the antenna units of the second millimeter wave antenna array 120 are located in a first frame area on one side of the second screen 12 parallel to the rotation axis;
wherein the first frame region includes: in the bezel or directly against the interior of the electronic device of the bezel.
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 center seam formed after the electronic device is folded, specifically, when 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 the 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 together form a target millimeter wave antenna array 130, the signals generated by the signal converter 300 may optionally enter the synchronization controller 200, enter the first radio frequency module 510 and the second radio frequency module 520 simultaneously after being subjected to power distribution, enter the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 after being subjected to synchronous modulation processing under the control of the synchronization controller 200, so that the two arrays are synchronously emitted as the target millimeter wave antenna array 130, and at this time, scanning of the millimeter wave antenna in two different directions, namely, scanning along a direction parallel to the antenna arrays (namely, a theta direction) and a direction perpendicular to the antenna arrays (namely, a phi direction) can be realized; the signal generated by the signal converter 300 can 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, and at this time, scanning of the millimeter wave antenna in one direction, namely scanning along the direction (namely theta direction) parallel to the antenna arrays can be realized; further, the reception is the inverse of the above 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 selectively enters 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, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 independently work, so that scanning of the millimeter wave antenna in one direction, namely scanning along a direction parallel to the antenna arrays (namely, a θ direction) can be realized; further, the reception is the inverse of the above transmission.
In this case, when the electronic device is in the closed state, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 may not only independently work, but also jointly form the target millimeter wave antenna array, so as to realize multidimensional scanning in the θ and Φ directions; when the electronic device is in the unfolded state, the first group 110 and the second group 120 of millimeter-wave antenna arrays are scanned along the θ direction, respectively.
In the second case,
As shown in fig. 6 to 9, the arrangement of the first group millimeter wave antenna array and the second group millimeter wave antenna array in this case is:
The antenna units of the first millimeter wave antenna array 110 are located in a second frame area on one side of the first screen 11 perpendicular to the rotating shaft, and the antenna units of the second millimeter wave antenna array 120 are located in a second frame area on one side of the second screen 12 perpendicular to the rotating shaft;
wherein the second frame region includes: in the frame of the first end, the interior of the electronic device facing the frame of the first end, in the frame of the second end or the interior of the electronic device facing 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 millimeter wave antenna array 110 and the second millimeter wave antenna array 120 and the rotation axis are respectively greater than or equal to the first set value, that is, when the electronic device is unfolded, the first millimeter wave antenna array 110 and the second millimeter wave antenna array 120 are insufficient to form the 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 center seam formed after the electronic device is folded, specifically, when 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 the closed state as shown in fig. 6 and fig. 7, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 together form a target millimeter wave antenna array 130, the signals generated by the signal converter 300 may optionally enter the synchronization controller 200, enter the first radio frequency module 510 and the second radio frequency module 520 simultaneously after being subjected to power distribution, enter the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 after being subjected to synchronous modulation processing under the control of the synchronization controller 200, so that the two arrays are synchronously emitted as the target millimeter wave antenna array 130, and at this time, scanning of the millimeter wave antenna in two different directions, namely, scanning along a direction parallel to the antenna arrays (namely, a theta direction) and a direction perpendicular to the antenna arrays (namely, a phi direction) can be realized; the signal generated by the signal converter 300 can 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, and at this time, scanning of the millimeter wave antenna in one direction, namely scanning along the direction (namely theta direction) parallel to the antenna arrays can be realized; further, the reception is the inverse of the above 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, 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, and at this time, scanning of the millimeter wave antenna in one direction (namely, scanning along a direction parallel to the antenna arrays (namely, direction θ) can be realized; further, the reception is the inverse of the above 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 not only independently work, but also jointly form a target millimeter wave antenna array, so as to realize multidimensional scanning in two angle directions of θ and Φ; when the electronic device is in an unfolded state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays are scanned along the theta direction respectively.
In the third case,
As shown in fig. 10 to 13, the arrangement of the first group millimeter wave antenna array and the second group millimeter wave antenna array in this case is:
the antenna units of the first millimeter wave antenna array 110 are located in a second frame area on one side of the first screen 11 perpendicular to the rotating shaft, and the antenna units of the second millimeter wave antenna array 120 are located in a second frame area on one side of the second screen 12 perpendicular to the rotating shaft;
Wherein the second frame region includes: in the frame of the first end, the interior of the electronic device facing the frame of the first end, in the frame of the second end or the interior of the electronic device facing 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 smaller than or equal to the 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 center seam formed after the electronic device is folded, specifically, when 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 the 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 together 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 emitted 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 (namely, scanning along a direction parallel to the antenna arrays (namely, a θ direction) can be realized; when signals enter the synchronous controller 200, the signals enter the first radio frequency module 510 and the second radio frequency module 520 simultaneously after power distribution, and enter the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 after synchronous modulation processing under the control of the synchronous controller 200, so that the two arrays are synchronously transmitted as target millimeter wave antenna arrays, and at the moment, the scanning of the millimeter wave antennas in two different directions can be realized, namely, the scanning along the direction parallel to the antenna arrays (namely, the theta direction) and the direction perpendicular to the antenna arrays (namely, the phi direction); further, the reception is the inverse of the above transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 12 and 13, the first group millimeter wave antenna array 110 and the second group millimeter wave antenna array 120 together constitute the large target millimeter wave antenna array 130, and the circuit logic in this case is the same as that in the case of the above-described electronic device in the closed state, except that the first group millimeter wave antenna array 110 and the second group millimeter wave antenna array 120 are synchronously operated as the target millimeter wave antenna array 130 to be synchronously emitted, at this time, scanning of the millimeter wave antenna in one direction, that is, scanning in the direction parallel to the antenna array (that is, θ direction) can be achieved, and in this case, double antenna gain and wider scanning angle can be obtained; further, the reception is the inverse of the above transmission.

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, 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, and at this time, scanning of the millimeter wave antenna in one direction (i.e. scanning along a direction parallel to the antenna arrays (i.e. direction θ) can be achieved; further, the reception is the inverse of the above transmission.
Specifically, when the electronic device is in the unfolded state as shown in fig. 16 and 17, the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 together form a target millimeter wave antenna array 130, the signal generated by the signal converter 300 can enter the first radio frequency module 510 or the second radio frequency module 520 through the switch 400, and enter the first group of millimeter wave antenna arrays 110 or the second group of millimeter wave antenna arrays 120 after synchronous modulation processing under the control of the synchronous controller 200, and at this time, scanning of the millimeter wave antennas in one direction (namely, scanning along a direction parallel to the antenna arrays (namely, θ direction) can be realized; the signal generated by the signal converter 300 can also enter the synchronous controller 200, enter the first radio frequency module 510 and the second radio frequency module 520 simultaneously after being distributed by power, enter the first group of millimeter wave antenna arrays 110 and the second group of millimeter wave antenna arrays 120 after being synchronously modulated under the control of the synchronous controller 200, so that the two arrays are synchronously transmitted as the target millimeter wave antenna array 130, and at the moment, the scanning of the millimeter wave antenna in two different directions can be realized, namely, the scanning along the direction parallel to the antenna array (namely, the theta direction) and the scanning along the direction perpendicular to the antenna array (namely, the phi direction); further, the reception is the inverse of the above transmission.
In this way, when the electronic device is in an unfolded state, the first group of millimeter wave antenna arrays and the second group of millimeter wave antenna arrays can work independently and also can jointly form a target millimeter wave antenna array to realize multidimensional scanning in two angle directions of theta and phi; 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.
