Engineering Physics Annotation << Back WIRELESS TRANSMISSION OF ELECTRICAL ENERGY FROM THE GROUND TERMINAL TO QUADROCOPTER W.I. KAGANOV, BUI HUU CHUC A wireless method of transmitting electrical energy to an unmanned aerial vehicle (quadcopter) by microwave radiation is considered The power of the microwave generator and the parameters of the phased antenna array of ground terminal for the implementation of this is calculated. The structure of construction of a semiconductor microwave generator based on gallium arsenide microwave transistors and Gunn diodes mwith the synchronization of their signals is determined. Key words: quadcopter, microwave radiation, active phased array, Gunn diode. DOI: 10.25791/infizik.01.2019.391 Contacts: E-mail: Kaganovwil@yandex.ru Pp. 34-38.
