Study of Different Dual-Reflectarray Antenna Configurations for Beam-Scanning Applications
Dual-reflectarray configurations exhibits some advantages from both mechanical and electrical points of view with respect to reflector antennas. Dual-reflectarray antennas present a reduced volume and the capability of being easily folded. Furthermore, these antenna configurations provide phase control on both reflectarray surfaces [1], which can be used to improve the antenna performance for m...
متن کاملDesign of a Bifocal Single Reflectarray Antenna with Improving Beam Scanning Performance
A novel scheme is introduced to design the high gain beam scanning reflectarray antennas for limited scan range application. At first, various existing schemes for beam scanning reflectarray antennas design are reviewed and it is concluded that as a convenient design scheme, the feed displacement technique is preferred for limited scan range applications. In order to improve the scan range, a b...
متن کاملDesign and Efficient Analysis of Large Reflectarray Antenna
In recent years reflectarray antennas have received considerable attention due to their unique capabilities. However, due to their large size, analyzing the performance of these antennas using traditional full wave finite-difference and finite-element techniques requires considerable computational resources. In this paper, we present an efficient method to accurately analyze these class of ante...
متن کاملCharacterization of Material Properties for Tunable Reflectarray Antenna Design
The emerging field of communications has increased the demand of electronically tunable reflectarray antennas. Substrate material properties play at1 important role in the design of reflectamy antennas. Variable permittivity materials such as liquid crystals and fenoelectrics have received great deal of attention due to their non-linear material properties. A comparative analysis behveen the pr...
متن کاملDesign of Broad-Beam Microstrip Reflectarray
The reflectarray’s elements arrangement for generating an arbitrary phase distribution in the antenna aperture and thus a wide beamwidth of the far field pattern is presented. The desired phase delay of reflectarray elements, which duplicated the same radiating aperture as backscatters, is determined on the construction of the curvature of a shaped backscatter surface with the help of Snell's l...
