METHOD OF FOCUSING FIELD OF N-ELEMENT ANTENNA ARRAY Russian patent published in 2024 - IPC H01Q25/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended for use in systems for wireless transmission of electromagnetic energy, primarily solar energy, by a radio beam focused on a ground section of receiving rectennas, as well as for radio communication. Reference signal s_ref(t) is generated by doubling the frequency of the signal received by the base element of the AA, and excitation signals of the AA elements are obtained by multiplying the received signals s_n(t) and the common reference signal s_ref(t), separating the signal with frequency ω₀ from this product.

EFFECT: simplified procedure of received signals processing and consequently easier technical implementation of the method.
