BALANCED DIPOLE ANTENNA FOR MOBILE PHONES

摘要

A balanced dipole antenna (600) for a mobile phone comprises a radiator element (604) and a counterpoise (608), both formed of a conducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) (612) of the mobile phone. A matching network, for example, a balun (616, 900, 1000, 1100), provides balanced current to the dipole antenna, resulting in a symmetric radiation pattern. The balanced dipole antenna (600) allows superior performance over conventional antennas found in mobile phones today by enabling a user of a mobile phone to communicate effectively and uniformly in all directions, that is, 360 degrees.
