<p>A dipole antenna (12) is composed of a meandering antenna element, which extends perpendicularly to the upper (horizontal) surface of a wireless communication terminal. The signal received at the dipole antenna (12) is sent to a transmitting and receiving circuit through a balanced-to-unbalanced transformer (13). The balanced-to-unbalanced transformer (13) minimizes the current flowing to a ground plane (11), thus preventing the ground plane (11) from acting as an antenna.</p> |
