Popis: This paper proposes a wireless power transmission system which used a printed circuit board operating as an antenna for both transmitter and receiver. The proposed antenna is driven by a high frequency full-bridge inverter which operates at self-resonant frequency of the antenna. Design procedure for the proposed antenna is also described. Results obtained from experimental test-rig confirm that the fabricated antenna provides self-resonant frequency at 2 MHz as design. The efficiency of the antenna can achieve the highest when the distance between transmitter and receiver is 40 mm in vertical alignment. The maximum total efficiency of proposed system is approximately 56.7 % at the distance between transmitter and receiver of 80 mm.
