Patent ID: 8723733

Claim:
A multiband antenna, comprising: a ground plane; a ground plane extension; and a plurality of antenna arms, wherein the ground plane, the ground plane extension, and the plurality of antenna arms are configured to communicate signals in multiple frequency bands, and wherein the ground plane and the ground plane extension have a length proportional to approximately a quarter wavelength of a frequency in the multiple frequency bands, and wherein the plurality of antenna arms comprises: a first antenna arm configured to communicate signals in a first frequency band; a second antenna arm configured to communicate signals in a second frequency band; and a third antenna arm configured to communicate signals in a third frequency band, wherein the first frequency band includes Cell and ISM bands, and the first antenna arm has a length proportional to approximately a quarter wavelength of a frequency in the Cell and ISM bands; the second frequency band includes GPS band , and the second antenna arm has a length proportional to approximately a quarter wavelength of a frequency in the GPS bands; and the third frequency band includes PCS band, and the third antenna arm has a length proportional to approximately a quarter wavelength of a frequency in the PCS band.
