Abstract :
We proposed a fractal antenna for wireless power transmission in order to improve power transmission efficiency. We demonstrate two fractal antennas. One of type of wire has efficiency of not less than 80% in spite of large position deviation, another of type of plate keeps a constant efficiency in opposition to position deviation and also has wide frequency band, while maximum power transmission efficiency is 55%.
