Abstract
Provided is a transmitter which can maximize the efficiency of rectification in a power-receiving electronic device irrespective of the distance therebetween. The transmitter transmits electric power to the electronic device through use of a microwave. The electronic device receives the microwave, converts the microwave to DC power, and uses the DC power as operation power. The transmitter includes a carrier wave generator for generating a carrier wave; a modulating signal generator for generating a modulating signal whose level increases, decreases, or increases and then decreases during one cycle; an amplitude modulator for amplitude-modulating the carrier wave generated by the carrier wave generator by, the modulating signal output from the modulating signal generator and for amplifying the modulated carrier wave and outputting the amplified, modulated carrier wave as a transmission signal; and an antenna for radiating the transmission signal output from the amplitude modulator into a space as the microwave.
