Abstract
The present invention provides a method and apparatus to manipulate the mutual coupling and the correlation between the antennas () on the handset () without the need to change the physical distance between them or to change their orientation. The manipulation in the mutual coupling and in the correlation is achieved using a circuit that is connected between the antennas' terminals () and the terminals () of the RF front end/power amplifier (). This circuit can be fixed or tunable. The coupling control takes place between two transmitting antennas () or two receiving antennas ().
