Claim:
1. A mobile device, comprising: a ground element; and an antenna structure, comprising: a ground branch; a feeding branch, having a feeding point, wherein the feeding branch is coupled through the ground branch to the ground element; a low-frequency radiation branch, coupled to the feeding branch; and a high-frequency radiation branch, coupled to the feeding branch; wherein the low-frequency radiation branch has a meandering structure; wherein the feeding branch and the low-frequency radiation branch are excited to generate a low-frequency band, the feeding branch and the high-frequency radiation branch are excited to generate a high-frequency band, the low-frequency band is substantially from 2400 MHz to 2484 MHz, and the high-frequency band is substantially from 5150 MHz to 5850 MHz; wherein a resonant path from the feeding point to the meandering structure of the low-frequency radiation branch has a length which is substantially equal to 0.125 wavelength of the low-frequency band, or 0.25 wavelength of the high-frequency band.
