Patent ID: 7119748

Claim:
A multiband antenna for use in a communications device operable in a first frequency range and a second frequency range, the second frequency range having higher frequencies two to three times the frequencies in the first frequency range, the communications device having a ground plane, said antenna comprising: a radiative element made substantially of an elongated strip of electrically conductive material, the strip having a first end and a second end, wherein the elongated strip has a first section adjacent to the first end and a second section adjacent to the second end electrically connected to the first section; a feeding point electrically connected to the first end of the radiative element; a grounding point adjacent to the feeding point, for electrically connecting the first end of the radiative element to the ground plane; and a further radiative element having an elongated segment made of electrically conductive material, and a grounding segment electrically connecting the elongated segment to the ground plane, wherein the elongated segment is disposed spaced from the radiative element and adjacent to one of the first and second sections of the elongated strip, and wherein the elongated strip has a length to provide resonance frequencies in the first frequency range, and the elongated strip is shaped such that the second section and the first section lie in axes substantially parallel to one another so that the placement of the second section relative to the first section together with the placement of the elongated segment of the further radiative element relative to the elongated strip provides resonance frequencies in the second frequency range.
