ABSTRACT:
An antenna coupler for a wireless communication system in a vehicle couples a transmit signal source to a plurality of antennas arranged within the vehicle. A first saturable reactor has a first load winding and a first control winding wound on a first saturable core, the first load winding coupling the signal source to a first antenna. A first current source is coupled to the first control winding for providing a selected current to the first control winding. A second saturable reactor has a second load winding and a second control winding wound on a second saturable core, the second load winding coupling the signal source to a second antenna. A second current source is coupled to the second control winding for providing a selected current to the second control winding. A controller is coupled to the first and second current sources for commanding the first and second selected currents to selectably attenuate or non-attenuate a transmit signal from the transmit signal source to each respective antenna.
