Abstract
A multiband antenna for a mobile device is disclosed. The mobile device includes a multiband antenna configured to communicate with a base station. The multiband antenna includes a ground plane, a ground plane extension, and a plurality of antenna arms. The ground plane, the ground plane extension, and the plurality of antenna arms are configured to communicate signals in multiple frequency bands, where 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. The mobile device further includes a modulator and demodulator configured to modulate signal for transmission and demodulate signal received from the base station, and a controller configured to control communication of signals using the multiband antenna and the modem.
