This paper presentsa dielectric resonator antenna (DRA) unit element that can be used for designing a compact reflectarray. Here, a rectangular DRA is incorporated with a top-loading metal strip where the strip inclination angle is used as the phase-shifting parameter. When modeled using the waveguide model, it is found that this DRA reflectarray unit element is able to give a reflection phase range of 162.29◦ . To understand further, the same unit element is also simulated using the Floquet model. It is found that the separation distance of the elements can affect the phase range and gradient of the S-curve significantly.
