Abstract

The problem of power transmission via a long microwave beam is usually solved by means of the creation of the field that falls at the antenna edges and its focusing toward the rectenna center. It is shown that phase synthesis may be realized with the use of an extra distribution of the radiated field phase. That optimal phase correction provides some power increase when the uniform law describes a radiated field distribution.
