The first bracket 120 is connected to the adjusting device 150 for mounting the first radiator 110, and the second bracket 140 is connected to the adjusting device 150 for mounting the second radiator 130.
The following will describe in detail various portions of the antenna assembly provided by the embodiments of the present disclosure:
the first radiator 110 is coupled to the second radiator 130, and the first radiator 110 and the second radiator 130 are disposed opposite to each other. An air layer is provided in the gap between the first radiator 110 and the second radiator 130, and the thickness of the air layer between the first radiator 110 and the second radiator 130 is adjusted by an adjusting device, thereby adjusting the coupling coefficient of the first radiator 110 and the second radiator 130.
The adjusting device 150 may include a driver 151 and a moving part 153, the driver 151 being connected to the first radiator 110; the moving part 153 is connected to the driver 151 and the second radiator 130, respectively, and the moving part 153 drives the second radiator 130 to move.
Wherein the driver 151 may be a linear motor or a rotary motor, and when the driver 151 is a linear motor, the linear motor may be connected to the first bracket 120. The antenna assembly is mounted to the electronic device and the linear motor and the first support 120 may be fixedly connected to the electronic device, i.e. the first support 120 and the linear motor may not be directly connected, but the relative positions of the first support 120 and the linear motor are fixed. In addition, the moving part 153 may be a slider, and the slider is disposed on the linear motor and can be driven by the linear motor to perform linear motion. The second bracket 140 is connected to the slider, and the second bracket 140 is driven by the slider to move along the guide rail of the linear electrode. The guide rail of the linear motor is perpendicular to the first bracket 120, and the second bracket 140 is parallel to the first bracket 120, that is, the linear motor can adjust the vertical coupling distance between the first radiator 110 and the second radiator 130, so that the antenna assembly can be adapted to different use environments.
When the driver 151 is a rotation motor, the rotation motor may be connected to the first bracket 120. The antenna assembly is mounted to the electronic device and the rotating motor and the first bracket 120 may be fixedly connected to the electronic device, i.e. the first bracket 120 and the rotating motor may not be directly connected, but the relative positions of the first bracket 120 and the rotating motor are fixed. On this basis, the moving portion 153 may include a transmission mechanism, which may be a lead screw slider mechanism, a rack and pinion mechanism, or the like.
When the transmission mechanism is a screw slider mechanism, the screw can be connected with the output shaft of the rotating motor, for example, through a coupling. The slider is connected with the second bracket 140 to drive the second bracket 140 to move along the extending direction of the lead screw. The first bracket 120 is perpendicular to the screw rod, the second bracket 140 is parallel to the first bracket 120, and the slider drives the second support rod to adjust the coupling distance between the first radiator 110 and the second radiator 130.
When the transmission mechanism is a gear-rack mechanism, the gear can be connected with the output shaft of the motor, and the rack is meshed with the gear and is connected with the second bracket 140. A guide groove may be provided on the electronic device, and the rack is provided in the guide groove. The guide groove extends in a direction from the first bracket 120 to the second bracket 140, i.e., the guide groove is perpendicular to the first bracket 120 and the second bracket 140 which are arranged in parallel. The gear is driven to rotate by the motor, so that the rack is driven to move along the guide groove, and the coupling distance between the first radiator 110 and the second radiator 130 is adjusted.
The driver 151 may be a servo motor or a stepping motor, and when the driver 151 is a servo motor, the servo driver 151 may be further disposed between the servo motor and the control unit 220, the control unit 220 sends a driving signal to the servo driver 151, and the servo driver 151 drives the servo motor to operate according to the driving signal. When the driver 151 is a stepping motor, a stepping driver 151 may be further disposed between the stepping motor and the control unit 220, the control unit 220 sends a driving signal to the stepping driver 151, and the stepping driver 151 drives the stepping motor to operate according to the driving signal.
The control unit 220 is connected to the adjusting device 150, and is configured to detect the impedance of the antenna, and control the adjusting device 150 to adjust the coupling distance between the first radiator 110 and the second radiator 130 according to the impedance of the antenna.
The control unit 220 may include a coupler 221 and a controller 222, where the coupler 221 is connected to the first radiator 110 and the second radiator 130, respectively, and is configured to detect a standing-wave ratio of the antenna assembly to obtain an impedance of the antenna; the controller 222 is respectively connected to the coupler 221 and the adjusting device 150, and is configured to control the adjusting device 150 to adjust the coupling distance between the first radiator 110 and the second radiator 130 according to the impedance of the antenna.
When the impedance of the antenna assembly is within the preset range during operation, the antenna assembly radiates normally, and when the impedance of the antenna assembly is detected to be out of the preset range, the controller 222 compares the current impedance of the antenna assembly with the preset impedance, and calculates the adjustment mode and the adjustment amount of the coupling distance between the first radiator 110 and the second radiator 130 according to the difference between the current impedance of the antenna assembly and the preset impedance. For example, if the difference between the current impedance and the preset impedance of the antenna assembly is greater than zero, the coupling distance between the first radiator 110 and the second radiator 130 is increased or the coupling distance between the first radiator 110 and the second radiator 130 is decreased.
For example, when the electronic device with the antenna assembly is in a different usage environment (e.g., the mobile phone is installed with a mobile phone shell or a user holds the mobile phone with his hand, etc.), the coupler 221 detects the standing wave ratio of the current antenna assembly. The controller 222 determines the impedance of the antenna assembly according to the standing wave ratio and adjusts the coupling distance of the first radiator 110 and the second radiator 130 according to the impedance of the antenna assembly. The controller 222 sends a driving signal to the driver 151 according to the coupling distance to be adjusted and the parameters of the driver 151.
The first support 120 and the second support 140 may be insulating material supports, so as to prevent the first support 120 and the second support 140 from being conductive and affecting the radiation performance of the antenna radiator. The first radiator 110 is disposed on the first support 120, and the first support 120 and the adjusting device 150 are fixedly connected to corresponding mounting portions of the electronic device.
The first radiator 110 includes at least one first sub-radiator, and the first sub-radiator is disposed on the first support 120. The antenna radiator needs to emit electromagnetic waves of multiple frequency bands, so that electromagnetic waves of different frequencies can be emitted through different first sub-radiators. For example, the number of the first sub-radiators may be two, three, four, six, or seven, etc., and certainly, the number of the first sub-radiators may also be other in practical applications, and the embodiment of the disclosure is not limited thereto.
The plurality of first sub-radiators are linearly distributed on the first support 120, and the plurality of first sub-radiators may be the same sub-radiator or different sub-radiators. For example, the first support 120 is a support rod, the first sub-radiator is a rectangular sheet metal, the plurality of first sub-radiators are sequentially connected to the support rod, and the first sub-radiators may be bonded to the support rod.
For example, when the first radiator 110 includes four first sub-radiators, the frequency segments of the first sub-radiators may be (24.25GHz 27.5GHz), (27.5GHz 28.35GHz), (28.35GHz 37GHz), and (37GHz 40GHz), respectively.

The second radiator 130 includes at least one second sub-radiator, and the second sub-radiator is disposed on the second support 140. The antenna radiator needs to emit electromagnetic waves of multiple frequency bands, so that electromagnetic waves of different frequencies can be emitted through different second sub-radiators. For example, the number of the second sub-radiators may be two, three, four, six, seven, or the like, and certainly, the number of the second sub-radiators may also be other in practical applications, and the embodiment of the disclosure is not limited thereto.
For example, when the second radiator 130 includes four second sub-radiators, the frequency segments of the second sub-radiators may be (34.25GHz to 37.5GHz), (37.5GHz to 38.35GHz), (38.35GHz to 47GHz), and (47GHz to 50GHz), respectively. Of course, in practical applications, the second radiator 130 may further include sub-radiators for transmitting other frequency bands, which is not specifically limited in this disclosure.
The plurality of second sub-radiators are linearly distributed on the second support 140, and the plurality of second sub-radiators may be the same sub-radiator or different sub-radiators. For example, the second support 140 is a support rod, the second sub-radiator is a rectangular sheet metal, a plurality of second sub-radiators are sequentially connected to the support rod, and the second sub-radiators may be bonded to the support rod.
The number of the second sub radiators is the same as that of the first sub radiators, and the second sub radiators correspond to the first sub radiators one to one. Of course, in practical applications, the number of the first sub-radiator and the second sub-radiator may also be different, and this is not specifically limited in the embodiments of the present disclosure.
When the first sub radiators and the second sub radiators are the same in number, and the second sub radiators and the first sub radiators correspond to each other, the first sub radiators and the second sub radiators are parallel to each other. The area of the second sub radiator is smaller than that of the corresponding first sub radiator, and the projection of the second sub radiator on the first sub radiator is positioned inside the first sub radiator.
