Abstract
A reflectarray antenna using flexible dielectric substrate is presented as a potential solution for high-gain THz antenna applications. The element phase compensation is achieved by appropriately tuning the flexible dielectric slab height. An equivalent circuit model is built to calculate the element reflection coefficient. A 30mm × 30mm square aperture dielectric reflectarray is then designed and analyzed. The numerical results demonstrate that this reflectarray can achieve good radiation performances; moreover the flexibility of the substrate makes the antenna suitable also for conformal situations.
