Abstract

The balancing of the antenna (AER2) of a mobile station card and an antenna interface (LNA) interrupts the access of interference (E) formed in the chassis of the electronic device acting as the host of the mobile station card through the antenna interface to disturb the radio reception of the mobile station card. The antenna has two elements that are placed to receive the interference emitted by a computer in a symmetric way. The antenna interface is balanced using a balun (Ba) or a differential antenna amplifier.
