Abstract
A balanced antenna system for a communication device includes a balanced transmission line electromagnetically coupled to a transceiver of the device. A symmetrical dipole antenna element is operable at a first frequency driven by the balanced transmission line. A symmetrical loop antenna shares portions of the dipole antenna element and is operable at a second frequency driven by the transmission line. Preferably, the antenna system is disposed within a flip portion of the device housing.
