PROBLEM TO BE SOLVED: To provide ground communication equipment capable of efficiently receiving an electric power wave sent from moving onboard communication equipment.SOLUTION: Included are an electric power wave receiving unit that receives an electric power wave, a driving voltage production unit that produces a driving voltage from the electric power wave received by the electric power receiving unit, a voltage regulation unit that includes a resistive component which works on the driving voltage produced by the driving voltage production unit, an action voltage production unit that produces an action voltage from the driving voltage outputted from the voltage regulation unit, a signal wave production unit that produces a signal wave using the action voltage, which is produced by the action voltage production unit, as an electric power source, and a signal wave radiation unit that radiates the signal wave produced by the signal wave production unit. When the driving voltage inputted to the voltage regulation unit gets higher, the resistive component of the voltage regulation unit gives a larger resistance. |
