The 180°Phase Shift Principle

SuperPreserva is a wave compensator (49 mm x 26 mm x 2 mm) containing a printed circuit and two circular microstrip antennae. Once you attach SuperPreserva to the back of your mobile phone, it emits compensation waves (green) which are shifted to 180¢X and identical to the waves (red) from your mobile phone and counteracts the potential harmful effects of the waves to the human body without interfering with the quality of communication.
