Dielectric Resonator Antenna as Reflectarray Element for Circular Polarization

摘要

In this paper, we are investigated a new structure for the circularly polarized reflectarray antenna using the element introduced in our previous paper. Here, the unit cell is created from the combination of four elements that are rotated sequentially. An array consisting of 64 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3-dB axial ratio bandwidth up to 31%. The results were validated using transmission line method (TLM).
