<p>A balanced antenna system for a communication device (101) includes a balanced transmission line (106) electromagnetically coupled to a transceiver of the device. A symmetrical dipole antenna element (105) is operable at a first frequency driven by the balanced transmission line. A symmetrical loop antenna share 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 (102) of the device housing.</p> |
