Abstract :
Sidelobe-level and ripple behaviors of Φ-symmetric shaped patterns, generated by circular, real and complex, continuous Taylor distributions, is analyzed as a function of measurement distances. This paper reveals that real distributions suffer less-significant power pattern degradation than complex distributions at near-field distances.
