Abstract

In this work, we present for the first time a multi-input and multi-output (MIMO) wireless power transmission system in which there are more than one source (transmitter antenna) and more than one load (receiver antenna). Theoretical expressions are developed to analyze the power transfer between antennas, power loss induced in each antenna and system efficiency of wireless power transfer. The theoretical model is verified with measurements in a prototype system consisting of two transmitter, two receiver and one repeater coils. Experimental results match well with theory demonstrating wireless power combining and delivering in the MIMO system.
