WebbAbstract:Beam shaping of array antennas has attracted the attention of many researchers for many years because of its primary application in tracking and ground mapping … WebbThe power equation for 2-D beam shape loss for an antenna with a Gaussian pattern, Lp2, is L p 1 = 8 ln 2 π = 1.7658 In decibels, the 1-D beam shape loss is 1.2338 and the 2-D beam shape loss is 2.4677. You can use beam shape loss for an antenna with a Gaussian pattern as an accurate approximation of loss for antennas with other patterns.
