Second directional coupler 162 is arranged to the position of the second antenna body B；Second signal receiver 172 connects the second directional couple
Device 162.
Directional coupler 161 and directional coupler 162 are respectively to detect metal antenna radiator 10 in two sections of setting frequencies
The radiation of section, feeds back to antenna condition for logic judgment result by the first signal receiver 171 and second signal receiver 172
Detection module 18, antenna condition detection module 18 are sentenced according to the logic of the first signal receiver 171 and second signal receiver 172
Disconnected result generates the testing result for being directed to first antenna ontology A and the second antenna body B.
Reference metal 14 such as being built in the metal alloy plate of mobile terminal, metal material inner casing, metal antenna spoke
14 separated by nonmetallic separator 15 to beam 10 and reference metal, is not electrically connected therebetween；Nonmetallic separator 15 rises
To the effect of waterproof sealing.
If mobile terminal is intake, so that with reference metal 14 short-circuit at water entry, the change of metal antenna radiator 10
The former grounding point of first antenna ontology A, so that the self-resonant frequency of first antenna ontology A changes, at this point, the first directional couple
Device 161 can not receive the radiation signal that radiation frequency is frequency three, and the generation of signal receiving device 171 can not receive radiation frequency
Rate is the logic judgment of frequency three as a result, feeding back to antenna condition detection module 18, and antenna condition detection module 18 then patrol by basis
It collects judging result and generates testing result: mobile terminal water inlet.The working method of second antenna body B is with first antenna ontology, no
It gives and repeating.
After antenna condition detection module 18 generates testing result, some execution modules can then generate according to testing result
Corresponding early warning operation, such as alarm described in embodiment one kind, cutting power supply etc., it will not go into details in the present embodiment.
In above-described embodiment one and embodiment two, the metal antenna radiator 10 and metal of nonmetallic 15 two sides of separator are joined
Examine the 14th length, the range that area as water inlet monitors, in practical application, originally according to the inlet area setting that need to actually monitor
Apply for the condition checkout gear for mobile terminal proposed.
Embodiment three
The present embodiment is applied to mobile terminal water inlet state-detection.In order to realize the electrostatic guarantor to first antenna signal source 11
Shield, can in the 13 earth inductance of match circuit of embodiment one, or metal antenna radiator 10 setting position with
Reference metal 14 connection so that metal antenna radiator be in PIFA antenna form.In this case, when mobile terminal water inlet makes
14 after certain point short circuit with obtaining metal antenna radiator 10 and reference metal, and the PIFA form of metal antenna radiator 10 is in antenna
The grounding point of arm is varied so that the change of resonance band occurs in metal antenna radiator 10, so as to according to resonance band
Change realize the detection of mobile terminal state.
As shown in figure 5, metal antenna radiator 10 with reference metal 14 is connect in setting position c and d, radiation frequency is formed
Rate is the PIFA antenna form of frequency five and frequency six, under mobile terminal flooded condition, the self-resonant frequency of primary antenna by
It destroys, PIFA the LOOP antenna form for forming radiation frequency as frequency seven and frequency eight passes through then as embodiment two
The detection of two groups of directional couplers and signal receiver equally provides testing result by antenna condition detection module 18, so as to
The operation such as alarmed according to testing result, cut off power supply is reached, protection is provided to mobile terminal internal circuit and battery, also warns
The water inlet state of customer mobile terminal.
In above-described embodiment one, embodiment two and embodiment three, metal antenna radiator 10 can be metal shell body
A part, can also using seal protect；In order to avoid holding the self-resonance for causing metal antenna radiator in situation
Frequency shift and cause to judge by accident, specific product application environment is considered in the design, in setting for directional coupler and signal receiver
In setting, the change situation of the self-resonant frequency in the case of human body need to be preset, for example, in the coupling frequency range of directional coupler setting
Including the resonance frequency point generated after human contact's metal antenna radiator.
The self-resonant frequency of metal antenna radiator 10 cannot be identical as the working frequency range of mobile terminal, makes to avoid interference
At erroneous judgement, meanwhile, which will be far from co-channel interference source
Example IV
The present embodiment is detected applied to mobile terminal handheld state.In mobile terminal as shown in FIG. 6 application, having can be with
Switch the first antenna 61 used and the second antenna 62, the upper and lower part of mobile terminal is respectively arranged at, in mobile terminal
In practical application, the second antenna positioned at lower part has performance in preferable antenna headroom but hand-held situation poor, positioned at top
First antenna headroom it is slightly worse but smaller by body effect, therefore two antennas will be switched over according to actual use situation,
Switch first antenna under handheld state to use, switches the use of the second antenna under non-handheld state.
For the use state for monitoring the second antenna, it is frequency nine that on the side of the second antenna 62, setting, which has self-resonant frequency,
Metal antenna radiator 10, first antenna signal source 11 connects metal antenna radiation by power amplification device 12 and match circuit 13
Body 10 is realized and is radiated in the self-resonance of frequency range nine.Directional coupler 16 examines the radiation regimes of metal antenna radiator 10
It surveys, and antenna condition detection module 18 is fed back to by 17 decision logic of signal receiving device, under non-handheld state, directional couple
Device 16 can detecte the radiation signal of frequency nine, and the decision logic of signal receiving device 17 is 1, when user's hand-held mobile terminal
Lower part when, curve 68 is the following are hand-held range, and metal antenna radiator and the second antenna are in hand-held range, due to human body
Capacitive effect, metal antenna radiator 10 generates frequency deviation as secondary radiation body, and directional coupler 16 can not receive radiation
Frequency is the signal of frequency nine, and the decision logic of signal receiving device 17 is 0, at this point, antenna condition detection module generates detection
As a result are as follows: user's hand-held mobile terminal lower part；Then antenna can be switched to first from the second antenna by antenna switch module
Antenna uses.
In the present embodiment, the condition checkout gear for being used for mobile terminal is placed in common hand position, when manpower is held
Afterwards, the self-resonant frequency of metal antenna radiator is changed, directional coupler can not receive the radiation of metal antenna radiator
The signal of frequency, antenna condition detection module may determine that this is used for the position that the condition checkout gear of mobile terminal is arranged and is in
Handheld state, by the switching of associated antenna switching module, more preferably antenna is used.
In the present embodiment, the second antenna of metal antenna radiator and required detection is in together under handheld state, from humorous
Vibration frequency is not identical as the working frequency of second antenna.
The condition checkout gear and mobile terminal for mobile terminal that above-mentioned the application proposes, using directional coupler with
Signal receiver is acquired and judges to the radiation signal of metal antenna radiator, the radiation frequency based on metal antenna radiator
