Abstract
Electrical energy from power plants to industrial facilities and settlements is mostly transmitted by wire-connected air or underground lines covering vast territories. However, in some rare cases there is a need for wireless transmission of electrical power to objects located in hard-to-reach areas. The problem of wireless transmission of electrical energy will become especially urgent as space electric power industry based on the placement of solar power plants in outer space is being developed. In this regard, several countries are conducting studies on the problem of electrical energy transmission using both laser and microwave radiation. The fundamentals of building systems for wireless transmission of electrical energy over short distances using microwave radiation are considered. Two options for constructing such systems are analyzed and calculated: using parabolic antennas and using phased array antennas. For both options the main parameters of systems for wireless transmission of electrical energy at 200 m were calculated. In the first case, powerful microwave devices are used: a magnetron or a direct-flight klystron; in the second case, microwave powerful field-effect transistors. For the second option the summation of the powers of microwave generators by means of their mutual synchronization is proposed.

The fundamentals of constructing systems for wireless transmission of electrical energy over short distances using microwave radiation were analyzed. Two options for constructing such systems were proposed: using parabolic antennas and using phased array antennas. For both options the main parameters of systems for wireless transmission of electrical energy at 200 m were calculated. In the first case, two powerful microwave devices, a magnetron or a direct-flight klystron, were used; in the second case, microwave powerful field-effect transistors were applied. For the second option the summation of the powers of microwave generators by means of their mutual synchronization is proposed.
