THREE-BAND ANTENNA DEVICE WITH RESONANCE GENERATION AND PORTABLE ELECTRONIC DEVICE HAVING THE SAME
First Claim
1. A three-band antenna device with resonance generation comprising:
- an isolating dielectric layer having a first surface and a second surface;
a first radiating element installed on the first surface for resonating to generate a first frequency band having a first center frequency, wherein a feeding part and a grounding part are installed on the first radiating element;
a second radiating element for resonating to generate a second frequency band with the first radiating element, the second frequency band having a second center frequency greater than the first center frequency, the second radiating element being installed on the second surface and stacked below the first radiating element across the isolating dielectric layer so as to generate a parasitic capacitance between the first radiating element and the second radiating element;
a feeding element connected to the feeding part for feeding; and
a grounding element connected to the grounding part;
wherein the parasitic capacitance between the first radiating element and the second radiating element and parasitic inductance of the second radiating element resonate to generate a third frequency band having a third center frequency, which is greater than the second center frequency.

Abstract
A three-band antenna device with resonance generation includes a dielectric layer having an upper surface and a lower surface, a grounding element, a first radiating element, and a second radiating element. The first radiating element is arranged on the upper surface for providing a first frequency band. The second radiating element is arranged on the lower surface and stacked below the first radiating element via the dielectric layer for providing a second frequency band, so as to generate a parasitic capacitance therebetween. A third frequency band is provided by the resonance of the parasitic capacitance and the parasitic inductance in the second radiating element.
