Abstract
Different power distribution methods of array antenna beamforming are analyzed. In this study, uniform half-wavelength inter-element spacing is considered to avoid grating lobe. Excitations to individual elements include Gaussian, Taylor's, Chebyshev's and Staircase Power Distribution (SPD). Design requirements include beam efficiency (BE), maximum sidelobe level (MSLL) and 3 dB beamwidth. A comparative study of these methods is carried out to full-fill the design goal.
