Performance of Planar Arrays for Microwave Power Transmission With Position Errors

An analytical method based on Statistical Analysis (SA) is proposed to predict the influence of position errors of planar array elements on microwave power transmission (MPT) efficiency. The average power pattern of arrays with arbitrary shape is formulated according to the rules of probability method. Then a closed-form expression describing the relationship between position errors and the average beam collection efficiency (BCE) is derived. A set of representative numerical experiments dealing with planar arrays of different sizes and shapes is reported and discussed to point out the effect of the position errors on MPT.
