Abstract
A cellular modem card that conforms to a PCMCIA standard includes a balanced antenna. The balanced antenna minimizes susceptibility to limited available ground plane and limited ground connections between the modem card and a host device, such as laptop computer. The balanced antenna may be a dipole antenna, loop antenna, capacitively loaded antenna, or any other suitable balanced antenna.
