Study of the Binomial Excitation of a Linear Broadside 10-Element Dipole Antenna Array

Aras Saeed Mahmood; Dlnya Aziz Ibrahim

A binomial array is a non-uniform antenna array for which the elements are equally spaced with unequal amplitude excitation using a specified current excitation known as binomial excitation. In this work a linear broadside dipole antenna is utilized to study the impact of the number, spacing and amplitude excitations of the elements on the radiation characteristics using 4NEC2 simulation software and compared to its analogues uniform array. 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. The best configuration achieving a 12.8 dBi gain was 10-element with 0.82λ spacing which may be used for GSM application at 1.8GHz frequency.
