The issues of wireless power transfer over short distances are considered. The approach may be used for wireless charging of batteries in unmanned vehicles. It is proposed to use the technique of microstrip structures for power transfer. The microstrip structures form a directional coupler on symmetrical strip lines when approaching by front parts. The length of the interaction lines is chosen several times longer than a quarter of the wavelength. Ballast resistors are excluded from the circuit. This approach leads to small losses of power transfer when the distance between microstrip structures changes over a wide range. Modeling of the operation of the power transfer system has been carried out, an experimental sample has been made and experimental studies have been carried out. The simulation and experiment are well accorded.
