Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
The technical scheme that the embodiment of the present disclosure provides is related to the antenna of terminal, the antenna in correlation technique as shown in figure 1,
Distributing point F both sides are provided with two switches, respectively switch S1 and switch S2, switch S1 and switch S2 can be with different conditions
Connected by the center of different inductance and terminal or the metal shell on the back of terminal so that antenna produces the radiation of different frequency.
Assuming that the antenna is not added with its caused radiation frequency during switch as shown in Fig. 2 resonance between 700-800MHz (megahertz)
Area can produce low frequency radiation, and 201 in its radiation curve such as Fig. 2, the resonance region between 1500-1700MHz can produce
202 in mid frequency radiated, its radiation curve such as Fig. 2, the resonance region between 2100-2300MHz can produce high frequency radiation, its
203 in radiation curve such as Fig. 2.But these three resonant frequencies are all very narrow, in order to realize the whole network of antenna in 700-2700MHz
Covering is, it is necessary to switch S1 and switch S2 switching various states, for example, with reference to shown in figure 2, switch S1 and switch S2 at least switch three
Kind working condition, antenna can produce the low frequency radiation of three frequencies respectively in the resonance region between 700-800MHz, radiate
Curve 201 in curve such as Fig. 2,201a and 201b；Switch S1 and switch S2 at least switches other three kinds of working conditions, and antenna is
