摘要

This paper proposes arbitrary shaped elements without beam shift for using a reflectarray. We optimize the resonant elements with orthogonal two axial symmetry by the genetic algorithm(GA). Effectiveness of the proposed elements is verified by discussing radiation characteristics of a fabricated offset reflectarray numerically and experimentally.
