Abstract :
The paper presents a method for decorrelating the antenna elements of a MIMO system in a compact handheld terminal at low bands. The architecture of the antenna system induces orthogonal currents over the closely spaced antennas resulting in a correlation free system. Nevertheless, due to the small electrical size of the balanced element, the bandwidth is reduced and the current density is increased thus generating higher Ohmic losses.
