Patent ID: 8259014

Claim:
A multi-loop antenna structure, comprising: a high-frequency radiating body; a low-frequency radiating body; a feeding connecting part used for electrically connecting one terminal of the high-frequency radiating body and one terminal of the low-frequency radiating body to a feeding point; and a grounding connecting part used for grounding the other terminal of the high-frequency radiating body and the other terminal of the low-frequency radiating body, wherein the feeding connecting part forms a first folded loop antenna with the high-frequency radiating body and the grounding connecting part for resonating at a first frequency band, the feeding connecting part forms a second folded loop antenna with the low-frequency radiating body and the grounding connecting part for resonating at a second frequency band, a third frequency band and a fourth frequency band, and the first folded loop antenna and the second folded loop antenna are folded for forming a three-dimensional structure.
