Abstract :
Here are discussed the methods and algorithms of the amplitude distribution synthesis needed for the increase of the wireless power transmission (WPT) efficiency. It is shown that the WPT efficiency is increased not only of the uniform or the taper distribution but and when the field intensity is raised at the edges of the radiating apertures. In this case the receiving antenna is illuminated uniformly enough and at the same time the level of the near side lobes is essentially decreased. Peculiarities of the requirements for the field are described. Algorithms of the phase and amplitude distribution are found.
