An alternative way to get more electrical energy for small low-orbit spacecraft (SC), based on wireless power transmission by microwave beam from the surface to improve the energy balance of the spacecraft and spacecraft control capabilities for emergency contingency system in its orientation is offered. The receiving subsystem of a wireless energy transfer – antenna-rectifier (rectenna) was designed. Rectenna has a two-layer structure and receive the electromagnetic wave with circular polarization. To realize this, the radiating antenna structure and rectifier are implemented as a system of orthogonal microstrip collinear conductors with the integrated Schottky open-frame diodes.
