This communication is aimed at problems associated with a functional neutralization of on-board radioelectronics systems of small-size unmanned aerial vehicles by high-power out-of-band radiation in microwave band.
Generalized scheme of large-aperture rectenna laticce is considered. Equation of state for an infinite rectenna lattice is obtained and proved that the calculation of its nonlinear regime is reduced to the calculation of parameters of “equivalent” receiving and rectifying element at fundamental frequency and frequencies of harmonics.
A concept of providing wireless power supply with microwave beam for pilotless aircrafts is introduced. The article presents justification of the choice of focusing type electromagnetic radiation (EMR) based on the requirements to the wireless power transmission (WPT) system. The features of the EMR focusing on receiving-rectifying antenna (rectenna) installed on movable objects are considered. With...
Potential abilities of receiving-rectifying elements (RRE) of rectennas based on Schottky diodes are estimated. In paper is suggested emitting structure of RRE which receive field on orthogonal polarizations, which allows increasing specific power of direct-current, collecting from square meter of rectenna aperture, decreasing its weight and dimensions and increasing its reliability.
The analysis of influence of electric and structural parameters of transmitting subsystem of wireless power transmission (WPT) to remote ground objects on the basis of the multi-position system of emitters (MSE) with the spatial-phase-frequency focusing of single-stage discrete (SSD) V-type of multifrequency radioimpulses is presented. Requirements to the values of a maximal possible error on the...
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...
