Abstract :
The numerical analysis of the characteristics of rarefied arrays of weakly directed radiators, located at an arbitrary height above a screen, is given. It is shown that certain array parameters lead to the maximum maximorum directivity, and that this is significantly higher than the gain factor of classical antenna arrays. The optimal distance between radiators increases with the height of the array over the screen.
