Fig. 2 shows the jagged slot plane of the unit cell in details. Corresponding to each coupling slot on PCB1, one set of jags with specified slopes is made in lateral edges of the jagged slot plane on the top layer of PCB2 in such a way that the jags meet coupling slots from their outer side. Reflectarray Antennas: Analysis and Synthesis Techniques International Journal of Antennas and Propagation is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles on the design, analysis, and applications of antennas, along with theoretical and practical studies relating the propagation of electromagnetic waves at all relevant frequencies, through space, air, and other media.

This article proposes a new kind of microstrip reflectarray ... microstrip reflectarray antenna with variable polarization ... with variable slots on ground plane. ... 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

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 Reflectarray Antennas: Analysis and Synthesis Techniques Radiation Analysis and Characteristics of Conformal Reflectarray Antennas: Analysis of Design Optimization of Bandwidth and Loss Performance of Reflectarray Antennas Based on Material Properties: Neural Network Characterization of Reflectarray Antennas: Recent Developments of Reflectarray Antennas in Dual-Reflector Configurations Dual Sized Varying Slot Lengths Loading Dielectric A DRA reflectarray with variable slot loading length supported on dielectric substrate with conducting ground plane is constructed as shown in Figure 1. 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
