Abstract
A portable wireless device for recharging batteries of vehicles, phones, and another apparatus is offered and described in this paper. Application of novel antennas, formed by sections of coupled radial spirals with dimensions significantly less than the operating wavelength in free space, makes it possible effective transmission RF energy from one object to another without radiation into surrounding medium.
