The frequency range of mode M1 can also be to include GSM 850, the frequency band of GSM 900, and its frequency range is 824 960MHz respectively
With 880 960MHz.It addition, mode M2 of display is the high order mode of mode M1 in Fig. 4.
First locked groove hole antenna structure 80 of this utility model embodiment is that 1/2nd wavelength close slot antenna, but phase
Ratio closes unlike slot antenna in traditional, and the first locked groove hole antenna structure 80 of this utility model embodiment has first can
Control electric capacity connecting portion 82.With reference to the return loss curve shown in Fig. 4, curve A1, A2, A3, A4 are that the first controlled capacitance connects respectively
Connect the result that the first controllable capacitance value is 2pF, 2.4pF, 2.8pF and 3.8pF in portion 82.From fig. 4, it can be seen that it is single when being controlled by control
When first controllable capacitance value of unit 100 increases, the operation frequency exciting mode of the first locked groove hole antenna structure 80 reduces.At this
Meanwhile, connect the first electric capacity C1 in the first low frequency feed side 812 of first antenna unit 81, the first ground connection of first antenna unit 81
End 813 series connection the first inductance L1, in order to help impedance matching.First antenna unit 81 is such as with the gold being printed on microwave base plate
Belong to structure to realize, be e.g. printed in long 25 millimeters, the microwave base plate of wide 6 millimeters.And first electric capacity C1 and the first inductance L1 be
Surface sticking assembly (SMD), e.g. chip capacity and chip inductance, all utilize stannum to connect mode and be conductively connected (series connection) respectively
One low frequency feed side 812 and the first earth terminal 813.In the present embodiment, the capacitance of the first electric capacity C1 is 2.4pF, the first electricity
The inductance value of sense L1 is 13nH, but the most therefore this utility model limits.It addition, the first earth terminal 813 may also set up switch, with
Control open circuit and short circuit so that when carrying out feed-in when the first low frequency feed side 812, make the first earth terminal (the first inductance of connecting
After L1) short circuit grounding (being connected to the ground connection of circuit system).
Refer to Fig. 5, be that the controlled capacitance connecting portion of Fig. 3 is removed and form the schematic diagram that closes slot antenna.If incite somebody to action this
The first controlled capacitance connecting portion 82 that Fig. 3 of utility model embodiment is provided removes, and low frequency to be reached is up to LTE 700
The impedance frequency range of the operation frequency of (698MHz 787MHz), then needing the extension of slotted eye is 135 millimeters (mm).
Refer to the return penalty values that Fig. 6, Fig. 6 are locked groove hole antenna structure, returning of Fig. 6 is lost compared to Fig. 4's
Return loss, it is seen that if not using the first controlled capacitance connecting portion 82 of this utility model embodiment, then the length of slotted eye need to be prolonged
Long (being extended to 135 millimeters by 105 millimeters), just can reach the operation frequency that lowest frequency is about LTE 700 (698MHz 787MHz)
The impedance frequency range of rate.It follows that the first controlled capacitance connecting portion 82 of this utility model embodiment can reach to reduce locked groove
The purpose of hole antenna structure size.
First radiofrequency signal is in addition to can being the signal of Long Term Evolution (LTE) frequency band, and the first radiofrequency signal is also
Can be GSM 850/900 (the 824 960 MHz) signal of frequency band, GSM 1800/1900/UMTS (1,710 2170 MHz)
The signal of frequency band, or the signal of LTE 2300/2500 (2,300 2690 MHz) frequency band.Or, the first radiofrequency signal also may be used
To be the signal of 2.4GHz frequency band, apply for 2.4GHz WLAN.Corresponding to the Antenna Design of Fig. 3, such as corresponding
Return in Fig. 4 is lost, and mode M1 can be applicable to the associated frequency band application less than 1GHz, and mode M2 can be applicable near 1.3GHz
Frequency band.Furthermore, then referring concurrently to Fig. 3 and Fig. 4, the first Department of Radiation 811 of first antenna unit 81 can provide the frequency to be
Resonance mode M3 near 2.4GHz, it is quarter-wave resonance mode.
Refer to Fig. 7, if the position of the first controlled capacitance connecting portion 82 is moved toward first antenna unit 81, be respectively by
The position of the first controlled capacitance connecting portion 82, toward first antenna unit 81 displacement 5 millimeters, 10 millimeters and 15 millimeters, returns loss song
Line is B1, B2, B3 respectively.It is to say, the distance of the first controlled capacitance connecting portion 82 and grounding points 70 be 14.5 millimeters,
19.5 millimeters, 24.5 millimeters time, return loss curve be B1, B2, B3 respectively.Curve is lost compared to the return before not moving
B0, if the first controlled capacitance connecting portion 82 is moved toward first antenna unit 81, the low-limit frequency of locked groove hole antenna structure 80
The mid frequency of operation mode can be lowered, and when the first controlled capacitance connecting portion 82 is closer to first antenna unit 81, then
The mid frequency of operation mode is the lowest.In short, the distance between the first controlled capacitance connecting portion 82 and first antenna unit 81
During shortening, the operation frequency exciting mode of the first locked groove hole antenna structure 80 reduces.This can be construed to, because of the first controllable electric
The capacitance holding connecting portion 82 can store bigger electric charge (for locked groove hole itself and first antenna unit 81), and
The electric current that can be excited antenna feed-in provides bigger electric current to guide degree, therefore can provide and be equivalent to extend current path
And cause the effect of frequency reducing.When the first controlled capacitance connecting portion 82 is closer to having (the first low frequency feed side, signal excitation source
812), during first antenna unit 81, the effect that equivalence extends current path is the most beneficial substantially so that the first locked groove hole antenna structure
The Frequency point of the resonance mode of 80 can be lowered further.
Referring to Fig. 3 and Fig. 8, first antenna unit 81 has more the first high frequency feed side 814, the first high frequency feed-in
End 814 connection the first Department of Radiation 811, the first high frequency feed side 814 is in order to feed-in the first high frequency radio signals.On the other hand, when
During the first low frequency feed side 812 FD feed, the first high frequency feed side 814 is open circuit.First high frequency radio signals is 5GHz frequency
The signal of band, can be used for WLAN (WLAN) or the WiFi application of 5GHz frequency band.When the first high frequency feed side 814 feed-in
During the first high frequency radio signals, the first low frequency feed side 812 then can be by being controlled by of being each connected with the first earth terminal 813
The switch of control unit 100 (figure does not illustrates) and be set as open-circuit condition.Now, the first Department of Radiation of first antenna unit 81
811 is the quarter-wave monopole with two branch roads, and short branch road is that the end extending to the first Department of Radiation 811 (leans on
Nearly first rotating shaft 50A), the length of short branch road is about 7 millimeters, and long branch road is to extend to the first low frequency feed side 812 (connect with first
Ground end 813) part, the length of long branch road is about 15 millimeters.But, above-mentioned size is only to illustrate, and is not limited to
This utility model.
