Abstract
A radio frequency (RF) noise reduction system is disclosed to include a first antenna for receiving a RF signal, a phase shifter coupled to the first antenna for generating a phase shifted RF signal, and an amplitude detector coupled to the first antenna for outputting a signal representative of an amplitude of the RF signal. Additionally, the RF noise reduction system includes a microcontroller coupled to the amplitude detector for controlling the phase shifter. Still yet, the RF noise reduction system includes a second antenna coupled to the phase shifter and being configured to transmit the phase shifted RF signal.
