Large, Multi-Faceted Reflectarray with Quasi-Constant Directivity in the V-Band

This work presents the simulations of an electrically large, multi-faceted reflectarray with a quasi-constant directivity of 44 dBi in the V-band. The paper shows the performance of an equivalent planar reflectarray to contrast the results. The comparison shows that the multi-faceted reflectarray renders a reduction in phase error. Moreover, this configuration increases the bandwidth up to the Q-band. It achieves a directivity of around 40 dB in contrast to the noisy radiation pattern from the equivalent planar reflectarray.
