Abstract:
1. An adaptive antenna neutralization network (AANN) for neutralizing coupling between a first antenna coupled to a first radio and a second antenna coupled to a second radio of a mobile terminal, the AANN comprising: an array of reactive branches, each reactive branch including a reactive element and an electrically controlled switch with a control input for selectively coupling the reactive element between the first antenna and the second antenna; a switch driver having an output coupled to the control input of each electrically controlled switch; and a controller having an output for sending control signals to the switch driver to turn on or off the electrically controlled switch of each reactive branch selected to produce anti-resonance to block an interfering signal from reactively coupling between the first antenna and the second antenna in response to a feedback signal generated by at least one of the first radio and second radio.
