Abstract:This paper presents a method based on iterative fast fourier technique to minimize peak side lobe level of a linear array of uniformly spaced isotropic antennas by 3-bit digital attenuator. One example has been presented with 30 isotropic antennas. The synthesis is performed by varying only discrete amplitude values of a 3-bit attenuator. Pattern generated is broadside when all excitation phases of the elements are kept constant, i.e. zero degree. Array factor is related to element excitations via inverse Four… Show more
