Wireless Power and Communication: Implementation of communication in a wireless power transferring system

Abstract

In this report two types of inductive antennas has been characterized, one designed for both power and communication and one designed for communication only. The effects of varying wire size, number of windings and distance separating the antennas has been discussed and it was found that the antennas designed exclusively for communication provided a higher power gain, larger bandwidth, higher tolerance against varying distance and the possibility for higher data rates. The antennas designed for both power and communication displayed a more gradual phase shifting property suggesting they would be more suitable for phase shifting modulation techniques. A simulation of a communication transfer using on-off keying was done in MATLAB, with very satisfying results.
