ANTENNA COUPLING FOR SENSING AND DYNAMIC TRANSMISSION Russian patent published in 2018 - IPC H04W52/24 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to communication. Disclosed wireless transmission system includes a receiver-transmitter pair. When a dielectric object approaches the transmitter-receiver pair, a signal strength of a transmitted carrier wave increases at the receiver. In response, transmission power of the transmitter can be dynamically reduced. When the dielectric object moves away from the transmitter-receiver pair, a signal strength of the carrier wave decreases at the receiver. In response, the transmission power of the transmitter can be dynamically increased.

EFFECT: providing a wireless transmission system that adjusts transmission power of a carrier wave responsive to a detected change in signal strength of the carrier wave at a receiver.
