Abstract:
1. A mobile device having a periphery and comprising: a ground plane disposed on a surface of a substrate; a feeding line disposed on the surface of the substrate and comprising a first line segment and a second line segment; a resonance element comprising a loop structure and formed on at least a portion of the periphery; a first feeding point and a second feeding point disposed on the resonance element wherein the first feeding point and the second feeding point are spaced apart by a distance, the first feeding point is electrically connected to a first end of the first line segment, the second feeding point is electrically connected to a second end of the first line segment, a first end of the second line segment is electrically connected to the first line segment, and the mobile device feeds a signal to a second end of the second line segment; and a first ground point and a second ground point disposed on the resonance element and electrically connected to the ground plane, wherein the resonance element comprises a first excitation path extending from the first feeding point to the first ground point and a second excitation path extending from the second feeding point to the second ground point, the first excitation path does not overlap the second excitation path, the resonance element receives and transmits a first radio frequency signal and a second radio frequency signal via the first excitation path, and the resonance element receives and transmits a third radio frequency signal via the second excitation path.
