A given configuration of a non-uniform antenna array for which the elements are equally spaced with unequal amplitude excitation using chebyshev excitation method has been studied in this work. The impact of the number, spacing and amplitude excitations of the elements on the radiation characteristics has been analyzed and compeared with its analogues of a linear broadside uniform and non-uniform binomial antenna arrays using 4NEC2 simulation software. The spacing between the elements varied from 0.1λ to 2λ in steps of 0.02λ for a number of elements up to 10 elements. For GSM application at 1.8GHz frequency the best configuration to achieve the required gain of 13.9dBi was 7-elements at 0.86λ spacing.
