Abstract :
An 8-element array of a waveguide crossed-slot with matching slots is designed based upon the MoM with numerical eigenmode basis functions. Radiation powers for the uniform excitation and axial ratios are refined iteratively using the infinite-finite array model. The main beam is formed in the desired direction in a circularly polarized wave of axial ratio less than 0.35dB.
