摘要： A load impedance decision device, a wireless power transmission device, and a wireless power transmission method are provided. At least one of a distance and an angle between two resonators may be measured. A load impedance may be determined based on at least one of the measured distance and the measured angle. When the distance between the two resonators changes, a high power transfer efficiency may be maintained without using a separate matching circuit. Where the load impedance is determined, a test power may be transmitted. Depending on a power transfer efficiency of the test power, the load impedance may be controlled and power may be wirelessly transmitted from the source resonator to the target resonator.

摘要： An RF MEMS switch having asymmetrical spring rigidity. The RF MEMS switch has supporting members spaced apart in a certain interval on a substrate, a membrane being a motion member suspended by plural spring members extended on both sides of the membrane, and a bottom electrode being a contact surface on an upper surface of the substrate facing a bottom surface of the membrane, wherein the plural spring members placed on opposite sides of the membrane have asymmetrical rigidity, and a portion of the membrane on a side of stronger spring rigidity is first separated from the contact surface when the RF MEMS switch is turned off. The present invention has an advantage of easy separation of the switch from the contact surface, when the switch is turned off, due to the different rigidity of the springs located on the sides of the membrane.
