1. A power generation system comprising:

  • a plurality of power generating modules;

    a module fixing device configured to fix the power generating modules onto an object; and

    a combining section,wherein each of the plurality of power generating modules includesa power generating module body including a power generator configured to generate DC energy, anda power transmitter attached to the power generating module body, the power transmitter including an oscillator that converts the DC energy into RF energy with a frequency f0 and a power transmitting antenna that is supplied with the RF energy from the oscillator and that transmits the RF energy as a resonant magnetic field, andwherein the module fixing device includesa first fixing member configured to fix the power generating modules,a plurality of power receiving antennas, each of the plurality of power receiving antennas corresponding to one of the plurality of power generating modules and configured to receive at least a part of the RF energy transmitted by a corresponding power transmitting antenna, anda second fixing member configured to fix the power receiving antennas, andwherein the first fixing member and the second fixing member are configured to fix the plurality of power generating modules and the plurality of power receiving antennas, respectively, such that each of the power receiving antennas faces at least partially the corresponding power transmitting antenna, andwherein the combining section is configured to combine the respective outputs of the power receiving antennas in parallel, andwherein the power transmitting antenna is a series resonant circuit in which a first inductor and a first capacitor are connected in series, andwherein the power receiving antenna is a parallel resonant circuit in which a second inductor and a second capacitor are connected in parallel, andwherein a resonant frequency fT of the power transmitting antenna and a resonant frequency fR of the power receiving antenna are set to be equal to the frequency f0 of the RF energy, andwherein the voltage step-up ratio Voc of the oscillator, the respective inductances L1 and L2 of the first inductor and the second inductor, and a coupling coefficient k between the power transmitting antenna and the power receiving antenna satisfy (L2/L1)≧

    4 (k/Voc)2.
