A wireless power transmission/reception apparatus includes a wireless power transmission unit. The transmission unit is configured to generate a wireless power signal to be transmitted, transmit the wireless power signal using magnetic resonance, receive a reflected wireless power signal from a wireless power reception unit, determine whether a load device is present, and transmit a further wireless power signal when it is determined that the load device is present in such a way that impedance and output power depending on variation in a distance to the load device are tracked, and wireless power is supplied to the load device in an optimized state. Accordingly, a separate transceiver module is not provided for the purpose of performing communication between a transmitting end and a receiving end, and a reception environment is automatically detected, thus enabling wireless power to be transmitted in an optimal wireless power transmission state.

Wireless power transmission/reception apparatus and method

A rigid flexible printed circuit board (PCB) and a method of fabricating the same. Since a polyimide copper clad laminate is not used during the fabrication of the rigid flexible PCB, an increase in cost resulting from use of the polyimide copper clad laminate and poor reliability of adhesion at an interface between different materials are avoided.
