Illustratively, as shown in figure 9, working as length L1 of the length L2 less than the first radiator 111 of the second radiator 121
When, in the case where the radiation frequency of antenna element is in the second frequency range (i.e. high-frequency range), terminal device can control antenna
The electric current flowing of unit is to the second radiator 121, to generate high-frequency resonant.Also, the is in the radiation frequency of antenna element
In the case where one frequency range (i.e. low-frequency range), the electric current that terminal device can control antenna element is flowed in the first radiator 111,
But it is not flow to the second radiator 121, to generate low-frequency resonant.It can specifically be determined according to actual use demand, the present invention is real
Example is applied to be not construed as limiting.
In the embodiment of the present invention, Fig. 7 and Fig. 8 are the stream of the electric current of antenna element when being in unfolded state with terminal device
Illustrated for dynamic path, in actual application, the electric current of antenna element when terminal device is in folded state
Flow path with when terminal device is in unfolded state the flow path of electric current of antenna element it is similar.Therefore, at end
The description of the flow path of the electric current of antenna element specifically may refer to above-mentioned such as Fig. 7 and Fig. 8 when end equipment is in folded state
Shown in associated description in embodiment, details are not described herein again.
Figure 10 shows structural schematic diagram when terminal device is in folded state.As shown in Figure 10, the first radiator 111
And second intercouple between radiator 121 connection, and in the electric current and the second radiator 121 in the first radiator 111
Electric current can identical or essentially identical (such as the difference between the numerical value of two electric currents is within a preset range), thus first radiation
Body 111 and the second radiator 121 will not interfere with each other, and will not generate clutter, and the second radiator of increase can make day
The area of the radiator of line unit increases, so as to promote the radiation efficiency of antenna element.Further, since the second radiator
121 and second there are a fixed spacing H between ground strip 22, thus the second ground strip 22 and first can be weakened to a certain extent
Electromagnetic coupling between radiator 111 and the second radiator 121, so as to further promote the radiation efficiency of antenna element.
Optionally, in the embodiment of the present invention, terminal device can (such as magnetic be sensed by sensor in terminal device
Device) screen of sensing terminal device is to be in folded state in unfolded state.Then, terminal device can be further according to
The state of screen controls and connects or disconnect between the first radiator and the second radiator.
Illustratively, in the embodiment of the present invention, pass through connecting element between above-mentioned first radiator and the second radiator
In the case where connection, terminal device can control connecting element and connect or break according to the different conditions of the screen of terminal device
It opens, connects or disconnect between the first radiator and the second radiator to control.To so that at the screen of terminal device
Antenna element has different performances when different conditions.So that antenna element can all have preferably in varied situations
Performance.
The embodiment of the present invention provides a kind of terminal device, which includes first shell, second shell, is set to this
The intracorporal first antenna module of first shell, and be set to intracorporal second Anneta module of the second shell, the first shell and should
Second shell is flexibly connected；The first antenna module includes the first radiator and the feed that connect with first radiator, this
Two Anneta modules include the second radiator；Wherein, second radiator and first radiator are electrically connected.With this solution,
The first shell and second shell of the terminal device are flexibly connected, and the terminal device is allowed to fold or be unfolded；And the end
End equipment includes antenna element, which includes the first radiator and the second radiator, compared with the prior art middle application
Antenna element in terminal device, the base of antenna element in terminal device provided in an embodiment of the present invention in the first radiator
The second radiator is increased on plinth, and the second radiator and the first radiator are electrically connected.On the one hand, due to increasing by the second radiation
Body can make the area of the radiator of antenna element increase, therefore can promote the performance of antenna element.On the other hand, at end
End equipment is under folded state, after increasing by the second radiator, connecing positioned at the second radiator side in terminal device
There can be a fixed spacing between ground piece and the second radiator in position, therefore the ground strip can be reduced to the second radiator
It influences, that is, reduces the ground strip to the electromagnetic coupling of antenna element, so as to promote the performance of antenna element.
It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or the device that include a series of elements not only include those elements, and
