The unit cell consists of rectangular DRA, with length L, width W, height H, a slot in the ground plane, with length L s and width W s, a dielectric layer of thickness h, and a conducting Design and Implementation of Reconfigurable Reflectarray Various reflectarray element designs were considered which included variable size patches, patch with variable length slot, patch with fixed slot fed by variable length stripline. After careful study and systematic evaluation, it was decided that the element – patch with variable length slot in the ground plane was best suited

Slotted Tunable Reflectarray Antenna in the scattering from patch and reflection from ground plane can be avoided. This effect therefore provides the opportunity to limit the mutual coupling effects. Another significant advantage is the reduction of phase errors. In the design of reflectarray with variable size patches, the phase errors occur due to the fact that the for A Reflectarray with Octagonal Unit Cells for 5-G Applications
