As D/W increase, Gain G increases as G = k * pi^2 * (D/W) ^2 .
As G = 4 * pi/w^2 * area as G increses, effective area increases as Directive gain increases target discrimination is easier.
As G = 4 * pi/w^2 * area as G increses, effective area increases as Directive gain increases target discrimination is easier.
