Summary:PURPOSE:To prevent breakdown of a rectifying diode by connecting a circuit which connects in series an auxiliary power supply and a switch in parallel with a rectenna element and then inserting a rectifying diode between the rectenna element and its output end. CONSTITUTION:In the case a rectenna element 1 has received a microwave signal while a switch 4 is turned on and an auxiliary power supply 2 drives a motor 6, if an output voltage of the rectenna element 1 does not exceed a voltage of the auxiliary power supply 2, a rectifying diode 3 is turned off. Therefore, an output end of the rectenna element 1 is opened but an output voltage of the rectenna element 1 is lower than the voltage which results in breakdown of the rectifying diode 3. Moreover, if an output voltage of the rectenna element 1 has exceeded a voltage of the auxiliary power supply 2, the rectifying diode turns on and the rectenna element 1 is connected with a motor 6. Thereby, breakdown of the rectifying diode 3 can be prevented while the rectenna element 1 and auxiliary power supply 2 are switched.
