Inductor between or capacitor and inductor between toggle switching to realize the tuning state of tuning circuit, switching
Different tuning states is corresponded to different capacitors, inductor.
The tuning state of tuner module includes at least two states of first state and the second state, naturally it is also possible to which setting is more
A state, the corresponding tuning state of each shielding status, determines corresponding relationship by surveying.For example, at antenna body
When shielding status 1, tuner module is adjusted so that antenna performance reaches optimum state, it is assumed that the tuning state of tuner module at this time
For tuning state 1, then establish the corresponding relationship of shielding status 1 Yu tuning state 1, i.e., when antenna body is in shielding status 1,
Then switch tuner module to tuning state 1.

When the left side of line ontology is shielded, then the tuning state of tuner module is switched to first state, to avoid antenna performance deterioration.
When the right that sensing module senses antenna body is shielded, then the tuning state of tuner module is switched to the second state,
To avoid antenna performance deterioration.
For being only provided with the situation of sensing unit on the left side of mobile terminal lower part, when sensing module senses antenna sheet
When the left side of body is shielded, then the tuning state of tuner module is switched to first state, antenna performance is avoided to deteriorate.In determination
After the left side of antenna body is shielded, when sensing module, which senses parasitic capacitance by sensing unit, to become smaller, it is determined that antenna
The left side of ontology does not have shielded, and the tuning state of tuner module is then switched back into the second state by switching module at this time, to prevent
The right of antenna body is shielded and influences antenna performance.In other words, under this situation, using the second state as tuner module
Default tuning state, just thinks that tuning state is just switched to first state when the left side of antenna body is shielded, to realize two
The switching of a tuning state.
For being only provided with the situation of sensing unit on the right of mobile terminal lower part, when sensing module senses antenna sheet
When the right of body is shielded, then the tuning state of tuner module is switched to the second state, to avoid antenna performance deterioration.True
Determine antenna body the right it is shielded after, when sensing module, which senses parasitic capacitance by sensing unit, to become smaller, it is determined that day
The right of line ontology does not have shielded, and the tuning state of tuner module is then switched back into first state by switching module at this time, to prevent
Only the left side of antenna body is shielded and influence antenna performance.In other words, under this situation, using first state as tuner module
