Abstract :
This paper presents a simple design of self-powered demodulator for wireless power and data transmission. An AM-modulated signal with the carrier frequency at 5.96GHz and modulating signal at 100MHz is received by the demodulator. The carrier component of the signal is utilized to be converted to DC level to power up the baseband amplifier that amplifies the demodulated signal. Therefore the external battery can be eliminated. In addition, a composite right/left-handed (CRLH) metamaterial based substrate-integrated-waveguide (SIW) antenna is used to make the whole circuit more compact.
