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)(More)
Results of investigations of construction principles of the modern wireless energy transmission (WET) microwave systems on the basis of the multi-position system of emitters (MSE) with focusing of single-stage discrete V-shape multifrequency signals and double-layer microstrip rectenna with circumpolarization in KHNURE are shown. Two variants of such(More)
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(More)
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(More)
A mathematical model of a large rectenna array (LRA) is presented. It is shown that matrices describing the LRA linear subsystem have a number of specific features that must be considered when the rectenna mathematical model is developed. The state equation for the LRA was obtained. It is shown that the model functioning in nonlinear mode of the infinite(More)
