Broadside linear array using discrete Gaussian current distribution
Abstract
An amplitude distribution for improving the radiation characteristics of a linear array is described. The elements are fed in phase and the current amplitude distribution of each element is given by a discrete Gaussian distribution function. By varying the standard deviation of the function the side lobe level is reduced considerably without substantial loss of beamwidth and gain. The proposed method gives a better beamwidth than the binomial current distribution with a reasonably low side lobe level (-34 dB), and does not require large current ratios as does binomial distribution. A better side lobe level was obtained than that resulting from triangular current amplitude distribution.
