Abstract: In this study, a dipole array antenna has been designed and simulated using triangular amplitude distribution for a different range of elements to establish and arrive at the benefit of low side-lobe level. The level of side-lobes is the result of element excitation amplitude and their positioning in the array, hence, an efficient amplitude distribution pattern has been implemented. The proposed non-uniform, element amplitude excitation design of antenna can be used for long-range, high-frequency and point-to-point communication applications. By implementing triangular amplitude distribution (Non-Uniform) the side-lobe level has been significantly reduced when compared to the uniform distribution. The simulated results confirm that the side-lobe, level has improved by -15.2 dB with the triangular distribution. The problem of high sidelobes, large beam-width and radiation spill-over can be suppressed with the proposed method of antenna array element excitation design, then the uniform-amplitude element excitation.
