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.

一个简单的自供电调幅解调器，用于无线电力/数据传输

提出了一种用于无线供电和数据传输的自供电解调器的简单设计。解调器接收载波频率为5.96GHz、调制频率为100MHz的调幅调制信号。利用该信号的载波分量转换为直流电平，为放大该解调信号的基带放大器上电。因此，可以消除外部电池。此外，采用复合左/右(CRLH)超材料基板集成波导(SIW)天线使整个电路更加紧凑。
