In the present invention, the first sheet metal and the second sheet metal are copper sheet or silver strip. Be preferably copper sheet, cheap, conduct electricity very well.
In the present invention, the first feeder line and the second feeder line select the material same with the first sheet metal and the second sheet metal to make. Be preferably copper.
When the same day, line worked in low-frequency range, the wavelength that the electromagnetic wave of low-frequency range is corresponding is longer, according to Antenna Design principle, the electric radiation length of feeder will increase thereupon and make feeder line physical length elongated, and longer feeder line also makes feeder loss increase simultaneously not only bad for the miniaturization of antenna entirety antenna overall performance is declined.
The present invention increases the effective radiating area of feeder line under the prerequisite that does not change feeder line physical length from two aspects. First aspect is by being arranged at the first sheet metal 10 and the second sheet metal 20 on first medium substrate 1, increases the swept area of feeder line by two sheet metals coupled relation each other. The first sheet metal 10 of 1 liang of apparent surface of first medium substrate can be connected with the second sheet metal 20, also can not connect. In the first sheet metal 10 and the unconnected situation of the second sheet metal 20, between the first sheet metal 10 and the second sheet metal 20 by capacitively coupled mode feed; In such cases, can realize the resonance of the first sheet metal 10 and the second sheet metal 20 by changing the thickness of medium substrate.

Second aspect, the 3rd sheet metal 30 that is arranged at second medium substrate 2 is coupled with the second sheet metal 20 that is arranged at first medium substrate B face, and to the 3rd micro groove structure 22 forming on the second sheet metal 20 and the 4th micro groove structure 23 feed that is coupled. On second medium substrate 2, be formed with plated-through hole 2000, plated-through hole 2000 can also can mutually stagger with 1 plated-through hole 1000 on first medium substrate on a vertical plane. Plated-through hole 2000 is electrically connected the second feeder line 101 and the 3rd sheet metal 30. The be coupled area of feed of the 3rd sheet metal 30 is easy to regulate, and only needs simply to adjust the coupling feed area of the 3rd sheet metal 30 for different working frequency range.
Said in the present invention " asymmetrical the first micro groove structure 12 and the second micro groove structure 13 " refers to, both do not form axially symmetric structure the first micro groove structure 12 and the second micro groove structure 13. In other words, can not find a symmetry axis on A surface, the first micro groove structure 12 is symmetrical arranged with relative this symmetry axis of the second micro groove structure 13.
In like manner, said in the present invention " asymmetrical the 3rd micro groove structure 22 and the 4th micro groove structure 23 " refers to, both do not form axially symmetric structure the 3rd micro groove structure 22 and the 4th micro groove structure 23. In other words, can not find a symmetry axis on B surface, the 3rd micro groove structure 22 is symmetrical arranged with relative this symmetry axis of the 4th micro groove structure 23.
In the present invention; the first micro groove structure 12 and the second micro groove structure 13 structures are asymmetric; the 3rd micro groove structure 22 and the 4th micro groove structure 23 structures are asymmetric; therefore in the time of antenna response electromagnetic wave; the equivalent capacity and the equivalent inductance that on two positions, form can be different; thereby produce at least two different resonance points, and the difficult counteracting of resonance point, be conducive to realize the abundant multimode of antenna.
The first micro groove structure 12 of the present invention can be the same with the version of the second micro groove structure 13, also can be different. And the degree of asymmetry of the first micro groove structure 12 and the second micro groove structure 13 can regulate as required. In like manner, the 3rd micro groove structure 22 of the present invention can be the same with the version of the 4th micro groove structure 23, also can be different. And the degree of asymmetry of the 3rd micro groove structure 22 and the 4th micro groove structure 23 can regulate as required. Thereby realize abundant adjustable multimode resonance.
And the present invention as required, on same a slice sheet metal, more micro groove structure can also be set, to make described antenna there are three above different resonant frequencies.
Concrete, the asymmetric situation in the present invention can have following embodiment.
Figure 1 shows that the A face visual angle structural representation of first medium substrate 1 first embodiment of the present invention.
