For viewpoint, first metal pivot part the 51, second metal pivot part the 52, first metal shell 4 and the second metal shell 6 all regard
For ground connection (being i.e. connected to the ground connection of the circuit system of electronic installation).
Refer to Fig. 3 B, the first concave part 411 of the embodiment of the present invention is identical with the shape of the second concave part 611, metal
Cover body 53 excites the electric current at the edge of the first concave part 411 and the electric current at the edge of the second concave part 611 to produce low frequency modal
With high order mode, the frequency of high order mode is higher than the frequency of low frequency modal.Based on the first concave part 411 and the second concave part 611
The identical situation of shape, metal cover body 53 excites the electric current at the edge of the first concave part 411 to be approximately identical to metal cover body 53
Excite the electric current at the edge of the second concave part 611, say, that metal cover body 53 excites the electricity at the edge of the first concave part 411
Stream and produce low frequency modal and high order mode, and metal cover body 53 excites the electric current at edge of the second concave part 611 also to produce
Low frequency modal and high order mode.
With reference to Fig. 4 and the return loss figure that combines Fig. 3 B, the mode of mid frequency about 2.4GHz is described Low-frequency Modes
State, the mode of mid frequency about 5.5GHz is described high order mode.First concave part 411 and second concave part of the present embodiment
611 is substantially the same, therefore the first concave part 411 is only described at this.The edge of the first concave part 411 can be determined by described below
Justice, it is that the first concave part 411 is at the first metal shell 4 with thickness T, long limit L that the first concave part 411 has long limit L, degree of depth D
The length that first side 41 is hollowed out, degree of depth D be the first concave part 411 by the first side 41 of the first metal shell 4 to first
The sinking degree of metal shell 4 inner recess, thickness T is the thickness of the first metal shell 4.Furthermore, on antenna design principles,
The frequency of low frequency modal is determined, via Computer Simulation meter by the total length (L+D) of the long limit L of the first concave part 411 with degree of depth D
Can find after calculation that metal cover body 53 is mainly distributed on the first concave part 411 for the electric current that the first metal shell 4 is excited
Edge, and on the first metal shell 4 away from the distance of the first concave part 411 more than a wavelength corresponding to antenna operating frequency
The electric current at place is the most small, therefore so that another rotating shaft 5 in Fig. 2 A (or Fig. 2 B), or distance the first concave part
411 substantially have no effect on the frequency of low frequency modal more than other metal assembly of a wavelength, therefore can such as use Fig. 3 C
Embodiment, only use a rotating shaft 5 can realize identical antenna performance.On the other hand, the frequency of high order mode mainly by
Spacing d(Fig. 3 B between long limit L and the metal cover body 53 of the first concave part 411 shows) determine.Specifically, spacing d adjustable
High order mode and the frequency ratio of low frequency modal.
In the situation that the first concave part 411 is identical with the shape of the second concave part 611, when being applied to WLAN
When 2.4GHz frequency band and 5GHz frequency band, the long limit L of the first concave part 411 and degree of depth D are 26 millimeters (mm) and 10 millimeters respectively
(mm), length W(Fig. 3 B of metal cover body 53 shows) it is slightly shorter than long limit L, e.g. 22 millimeters, now the frequency of low frequency modal can be contained
The frequency band of lid 2.4GHz.Further, spacing d between long limit L and the metal cover body 53 of the first concave part 411 is 2 millimeters (mm), can
The frequency making high order mode contains the frequency band of 5GHz, refer to the return loss figure of Fig. 4.On the other hand, at the first concave part 411
In the case of differing with size with the shape of the second concave part 611, the low frequency that metal cover body 53 excites with the first concave part 411
Mode then differs the low frequency modal and high order mode excited in metal cover body 53 with the second concave part 611 with high order mode, also
That is antenna structure can produce low frequency modal and the high order mode of two different frequencies of two different frequencies, the most also
Spendable frequency range and application frequency band may be increased.But, the present invention does not limit the first concave part 411 and the second concave part
611 is the most identical.
Furthermore, the feeding portion 541 of feed-in unit 54 can have match circuit, with the antenna allowing the embodiment of the present invention provide
Structure can realize good radio communication in the different use patterns of notebook computer.
Refer to Fig. 5, the feeding portion 541 of feed-in unit 54 include microstrip line M, the first inductance L1, the first electric capacity C1 and
Second inductance L2, wherein the first inductance L1 and the first electric capacity C1 series connection microstrip line M, the second inductance L2 are connected to microstrip line M and connect
Between ground portion 542, the second inductance L2 being arranged in Figure 5 on microwave base plate utilizes the perforation of microwave base plate to be conductively connected microwave
The ground plane (being the some of grounding parts 542) of substrate back.In order to reach preferably impedance matching, the of the embodiment of the present invention
It is preferable that the inductance value of one inductance L1 is chosen to be 4.2nH, and it is preferable that the capacitance of the first electric capacity C1 is chosen to be 5.8pF, and second
It is preferable that the inductance value of inductance L2 is chosen to be 27nH, but the most therefore the present invention limits.On the other hand, the switch of feed-in unit 54
S is connected between grounding parts 542 and metal cover body 53, and switch S is controlled by the circuit system of notebook computer (electronic installation)
Control signal and turn on or be not turned on, eliminate the control circuit of switch S in the drawings, the triggering of control signal or set (such as
It is magnitude of voltage size) can determine according to the design of circuit system, but the present invention is not limiting as controlling what whether switch S turned on
Mode.
