Resumen
This document presents the design and manufacture of a reflectarray (RA) antenna for the
Ku-band that is based on a fully-metallic 3D architecture. The reflectarray unit cell is formed by a
square-shaped waveguide section ending in a short circuit, which is the reflectarray back ground
plane. Each cell has the ability of configuring the phase of its own reflected field by means of
resonators perforated on the walls of the cell waveguide section. The resonator-based waveguide
cell introduces the 3D character to the design. The geometry of the resonators and the size variation
introduces the phase behavior of each cell, thus, conforming the radiation pattern of the reflectarray. This design explores the potential of phase value truncation (six states and two states) and
demonstrates that proper pattern results can be obtained with this phase truncation.
