Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to a first embodiment of the present application. The electronic apparatus 1 includes, but is not limited to, a smart phone, an internet device (MID), an electronic book, a Portable Player Station (PSP), a Personal Digital Assistant (PDA), or other devices having a communication function.
The electronic device 1 comprises an antenna assembly 10. The antenna assembly 10 includes a first rf signal source 110, a first antenna radiator 120, a second antenna radiator 130, a first adjusting circuit 140, a second adjusting circuit 150, a mode switch 160, and a controller 170. The controller 170 is configured to generate a first control signal, a second control signal, and a third control signal. The first rf signal source 110 is configured to generate a first rf signal, and the first adjusting circuit 140 is configured to adjust the equivalent electrical length of the first antenna radiator 120 under the control of the first control signal, so that the first antenna radiator 120 generates first electromagnetic wave signals with different frequency bands according to the first rf signal. The second antenna radiator 130 includes a first portion 131 disposed adjacent to the first antenna radiator 120, and a predetermined gap 120a is disposed between the first portion 131 and the first antenna radiator 120, wherein the first portion 131 couples the first electromagnetic wave signal and generates a second electromagnetic wave signal. The mode switch 160 receives the second control signal, and when the mode switch is in the first state under the control of the second control signal, the second adjusting circuit 150 is electrically connected to the first portion 131, and the second adjusting circuit 150 adjusts the equivalent electrical length of the first portion 131 under the control of the third control signal, so that the first portion 131 radiates the second electromagnetic wave signal.
Further, the first rf signal is loaded at one end of the first antenna radiator 120 adjacent to the second antenna radiator 130. The loading of the first rf signal at the end of the first antenna radiator 120 adjacent to the second antenna radiator 130 can increase the coupling energy of the second antenna radiator 130 to couple the first electromagnetic wave signal radiated by the first antenna radiator 120, thereby increasing the power of the second electromagnetic wave signal.
In this embodiment, the first adjusting circuit 140 is a frequency band adjusting circuit, the first adjusting circuit 140 may include an inductor or a capacitor, and the first adjusting circuit 140 adjusts the equivalent electrical length of the first antenna radiator 120 under the control of the first control signal, so that the first antenna radiator 120 generates a first electromagnetic wave signal with different frequency bands according to the first radio frequency signal, and the first electromagnetic wave signal is radiated by the first antenna radiator 120. Since the second antenna radiator 130 is disposed adjacent to the first antenna radiator 120 and a predetermined distance is disposed between the first portion 131 of the second antenna radiator 130 and the first antenna radiator 120, the first portion 131 of the second antenna radiator 130 couples the first electromagnetic wave signal and generates a second electromagnetic wave signal according to the first electromagnetic wave signal. When the second adjusting circuit 150 is electrically connected to the first portion 131, the second adjusting circuit 150 adjusts the equivalent electrical length of the first portion 131 under the control of the third control signal, so that the adjusted equivalent electrical length of the first portion 131 matches the electrical length required for radiating the second electromagnetic wave signal, so as to radiate the second electromagnetic wave signal.
Specifically, when the first adjusting circuit 140 includes an inductor, when the inductor is connected to the first antenna radiator 120, the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120 is increased. The larger the inductance value of the inductor is, the smaller the amplitude of the increase of the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120 is, and the smaller the inductance value of the inductor is, the larger the amplitude of the increase of the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120 is. When the first adjusting circuit 140 includes a capacitor, the capacitor, when connected to the first antenna radiator 120, causes the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120 to decrease. The larger the capacitance value of the capacitor, the larger the amplitude of the reduction of the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120. The smaller the capacitance value of the capacitor, the smaller the amplitude of the reduction of the frequency of the first electromagnetic wave signal radiated by the first antenna radiator 120.
Further, the antenna assembly 10 further includes a first impedance matching circuit 180. The first impedance matching circuit 180 is configured to adjust an output impedance of the first rf signal source 110, and the first impedance matching circuit 180 is further configured to adjust an input impedance of the first antenna radiator 120, so as to adjust a matching degree between the output impedance of the first rf signal source 110 and the input impedance of the first antenna radiator 120. The antenna assembly 10 of the present application reduces the energy loss of the first radio frequency signal emitted from the first radio frequency signal source 110 to the first antenna radiator 120 by adjusting the output impedance of the first radio frequency signal source 110 and the input impedance of the first antenna radiator 120, so as to improve the signal transmission quality of the first radio frequency signal emitted from the first radio frequency signal source 110, and improve the communication quality of the electronic device 1 to which the antenna assembly 10 is applied.
Further, the antenna assembly 10 further includes a second rf signal source 190, the second rf signal source 190 is configured to generate a second rf signal, the first portion 131 includes a feeding point 131a, the feeding point 131a is located at an end of the first portion 131 away from the first antenna radiator 120, the second rf signal is loaded on the feeding point 131a, when the mode switch 160 is controlled by the second control signal to be in the second state, the second adjusting circuit 150 is electrically disconnected from the first portion 131, and the second antenna radiator 130 generates a third electromagnetic wave signal according to the second rf signal and radiates the third electromagnetic wave signal.
When the size of the preset gap 120a between the first portion 131 of the second antenna radiator 130 and the first antenna radiator 120 is larger, the energy of the first portion 131 of the second antenna radiator 130 coupled to the first electromagnetic wave signal is smaller; conversely, the smaller the size of the preset gap 120a between the first portion 131 of the second antenna radiator 130 and the first antenna radiator 120, the greater the energy of the second portion 132 of the second antenna radiator 130 coupled to the first electromagnetic wave signal. When the energy coupling of the first portion 131 of the second antenna radiator 130 to the first electromagnetic wave signal is too small, the power of the second electromagnetic wave signal radiated by the first portion 131 is small, which is not favorable for the electronic device 1 to which the antenna assembly 10 is applied to communicate with the second electromagnetic wave signal. When the energy coupled to the first electromagnetic wave signal by the first portion 131 of the second antenna radiator 130 is too large, the energy coupled to the first portion 131 may affect the third electromagnetic wave signal radiated by the second antenna radiator 130, even making the third electromagnetic wave signal unusable. Therefore, in view of the above, the size of the predetermined gap 120a is selected from 1 to 2 mm, and preferably, the size of the predetermined gap 120a is 1.2 mm, or 1.5 mm, or 1.8 mm.
Further, the first electromagnetic wave signal is a high frequency signal, the second electromagnetic wave signal is an intermediate frequency signal, and the third electromagnetic wave signal is a low frequency signal. In this embodiment, the frequency band of the first electromagnetic wave signal ranges from 2300MHZ to 2690MHZ, the frequency band of the second electromagnetic wave signal ranges from 1710MHZ to 2170MHZ, and the frequency band of the third electromagnetic wave signal ranges from 700MHZ to 960 MHZ.
Further, the second antenna radiator 130 further includes a second portion 132 disposed opposite to the first portion 131, and the second portion 132 is grounded. Since the first portion 131 is disposed at an end of the second antenna radiator 130 adjacent to the first antenna radiator 120, the second portion 132 is disposed at an end of the second antenna radiator 130 away from the first antenna radiator 120.
Further, the antenna assembly 10 further includes a coupling capacitor C through which the second radio frequency signal is loaded to the feeding point 131a, so that the second antenna radiator 130 forms an open loop antenna (open loop antenna). The capacitance value of the coupling capacitor C is usually 0.5-3.0 pF. When the second radio frequency signal is directly fed to the feeding point 131a, the second Antenna radiator 130 is caused to form an Inverted F Antenna (IFA). Generally, the electrical length required by the open-loop antenna to radiate the electromagnetic wave signal with the predetermined frequency is (1/8-1/4) λ, and the electrical length required by the inverted-F antenna to radiate the electromagnetic wave signal with the predetermined frequency is λ/4, where λ is the wavelength of the electromagnetic wave signal. The electrical length required for the open-loop antenna to radiate electromagnetic wave signals of the same frequency is shorter than that required for the inverted-F antenna, and thus it can be seen that the antenna assembly 10 includes a coupling capacitor C to which the second radio frequency signal is applied at how many feed points 131a so that the second antenna radiator 130 forms an open-loop antenna is advantageous for miniaturization of the antenna assembly 10.
Further, the antenna assembly 10 further includes a second impedance matching circuit 210. The second impedance matching circuit 210 is configured to adjust an output impedance of the second rf signal source 190, and the second impedance matching circuit 210 is further configured to adjust an input impedance of the second antenna radiator 130, so as to adjust a matching degree between the output impedance of the second rf signal source 190 and the input impedance of the second antenna radiator 130. The antenna assembly 10 of the present application reduces the energy loss of the second radio frequency signal transmitted to the second antenna radiator 130 by adjusting the output impedance of the second radio frequency signal source 190 and the input impedance of the second antenna radiator 130, so as to improve the signal transmission quality of the second radio frequency signal transmitted by the second radio frequency signal source 190, and improve the communication quality of the electronic device 1 to which the antenna assembly 10 is applied.
Compared with the prior art, in the antenna assembly 10 of the present application, the first antenna radiator 120 adjusts the equivalent electrical length of the first antenna radiator 120 under the control of the first control signal, so that the first antenna radiator 120 generates the first electromagnetic wave signals of different frequency bands, the frequency band of the first electromagnetic wave signal is extended, and the frequency band of the first electromagnetic wave signal is wider. The first portion 131 of the second antenna radiator 130 couples the first electromagnetic wave signal to generate a second electromagnetic wave signal, and since the frequency band of the first electromagnetic wave signal is wider and the frequency band of the second electromagnetic wave signal is correspondingly wider, the frequency band of the electromagnetic wave signal radiated by the antenna assembly 10 of the present application is wider, thereby improving the communication effect of the electronic device 1 to which the antenna assembly 10 is applied.

When the control terminal 161 controls the first terminal 162 and the second terminal 163 to be disconnected under the control of the second control signal, the frequency band matching circuit is electrically disconnected from the first portion 131.

In this embodiment, the second end 163 is electrically connected to the feeding point 131a, so that the position where the second adjusting circuit 150 is electrically connected to the first antenna radiator 120 is the same as the position where the second rf signal source 190 loads the second rf signal onto the second antenna radiator 130, the position of the connection point to the second antenna radiator 130 can be reduced, so that the second adjusting circuit 150 is electrically connected to the second antenna radiator 130 and the second rf signal is loaded onto the second antenna radiator 130 to share one electrical connector, thereby facilitating the miniaturization of the antenna assembly 10.
In addition, the second adjusting circuit 150 is connected to the second antenna radiator 130 and the second rf signal is applied to the second antenna radiator 130 to share one electrical connector, so that the feeding point 131a of the second antenna radiator 130 is more likely to be disposed at a side of the first portion 131 away from the second portion 132, that is, the feeding point 131a of the second antenna radiator 130 and the grounding point of the second antenna radiator 130 are increased, thereby making the second rf signal flow more uniformly on the second antenna radiator 130, further increasing the bandwidth of the third electromagnetic wave signal generated by the second antenna radiator 130 and increasing the communication band of the electronic device 1 to which the antenna assembly 10 is applied.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an electronic device according to a third embodiment of the present application.

The first antenna radiator 120 and the second antenna radiator 130 are movably connected to the device body 30, so that the first antenna radiator 120 and the second antenna radiator 130 extend out of the device body 30, thereby increasing the clearance of radiation from the first antenna radiator 120 and the second antenna radiator 130, and increasing the radiation effect of the first antenna radiator 120 and the second antenna radiator 130.
In this embodiment, the electronic device 1 further includes a frequency deviation corrector 40, and the frequency deviation corrector 40 is configured to perform frequency deviation correction on the electromagnetic wave signal radiated by the first antenna radiator 120 and the electromagnetic wave signal radiated by the second antenna radiator 130 when the positions of the first antenna radiator 120 and the second antenna radiator 130 are changed compared with the device body 30.
