The utility model multi-band internal antenna, described grounded metal band are tuning capacity formula or tuning coil formula.
The beneficial effects of the utility model are:
1) the little and section height of antenna volume effectively reduces
This antenna adopts the two-dimentional machinery structure, has avoided the large scale on the one dimension direction.Ground wire antenna section height effective depth can effectively reduce by wriggling;
2) increased the flexibility of Antenna Design
Mainly contain the characteristic of two aspects: one, physically, by changing earth connection in the position of antenna branch, the center resonant frequency of multi-band operation can change in flexibility; Its two, if do not change earthing position, and change the folding mode of earth connection, multi-band operation also can be realized;
3) sinuous grounded metal earth connection can provide the antenna fixed support, has improved the antenna system reliability and stability; At extreme environment, such as strong vibration, by connecting the metal earth connection to device housings, fixed antenna guarantees the antenna reliably working effectively;
4) need not extra passive lamped element
Passive lamped element is introduced the loss that will cause antenna in the impedance matching network increases, thereby the efficient of system reduces.Adopt earth connection to improve radiation resistance, reduced effective input reactance, thereby obtained desirable efficient, be highly suitable in the unlimited equipment of ultra low power and use from coupling.
