Patent ID: 8059042

Claim:
A shorted monopole antenna made from a single metal sheet, comprising: a ground portion having a short edge and a long edge having a signal grounding point; a shorting portion folded and extended upwardly from the short edge of the ground portion near the signal grounding point; a radiating portion having a first radiating section and a second radiating section, the first radiating section and the second radiating section defining a single path of resonance at a single frequency band, wherein the first radiating section is folded from the shorting portion and configured substantially parallel to the ground portion, the second radiating section is folded from the first radiating section at a specific angle and has a signal feeding point corresponding to the signal grounding point, the first radiating section and the second radiating section are joined by a bent section; and a coaxial cable having an inner conductor and an outer conductor, the inner and the outer conductors being connected electrically to the signal feeding point and the signal grounding point respectively; wherein the shorted monopole antenna is formed by folding the single metal sheet, the single metal sheet has an elongated portion and a protruding portion extending partially from the elongated portion, the elongated portion is defined as the ground portion, the shorting portion and the first radiating section of the radiating portion, and the protruding portion performs as the second radiating section of the radiating portion.
