Caracterização Numérica de Células Unitárias com Linhas de Atraso de Fase para Redes Refletoras Impressas

This paper presents the phase responses of circular-shaped scaterrers with phase-delay lines for operation at 9.6~GHz. The curves indicate a wide range of phase values obtained by varying the length of the phase-delay lines. The behavior of the three analyzed structures is suitable for the integration into a reflectarray in the future.
