Patent ID: 7728783

Claim:
An antenna structure, comprising: a connection portion; a feed portion connecting to the connection portion, defining a feed point; an inductance portion, extending from the connection portion, a free end of the inductance portion connecting to a ground end; a capacitance portion in a long narrow strip shape, extending from the connection portion, parallel with and adjacent to the ground end; and at least one radiating portion, connecting to the connection portion respectively; and wherein the inductance portion is L-shaped; wherein the connection portion horizontally extends leftward and then bends downward to form the L-shaped inductance portion, so the inductance portion has a transverse inductance strip perpendicularly extending from the left side of the connection portion and a longitudinal inductance strip perpendicularly extending from a rear end of the transverse inductance strip, the free end of the longitudinal inductance strip connects with the ground end.
