Abstract: This manuscript presents the design, implementation, and validation of two microstrip feeding networks for 8-element linear antenna arrays, based on triangular and binomial amplitude distributions. The networks are built using cascaded Wilkinson power dividers and T-type resistive attenuators to achieve the desired excitation profiles. Electromagnetic simulations and experimental measurements of the S-parameters confirm strong agreement with the theoretical distributions, with absolute errors below 1.3 dB for the triangular network and up to 4.9 dB for the binomial configuration. Furthermore, the measured amplitude profiles are applied to a linear array of isotropic sources to evaluate the radiation pattern. Results demonstrate that the triangular distribution effectively reduces side lobes, while the binomial distribution nearly eliminates them. These findings validate the proposed design methodology and its applicability in antenna systems requiring precise control of the radiation pattern and side-lobe suppression.
