Design 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 کاملRing Shaped Compact Microstrip Reflectarray Antenna
Regularly shaped compact microstrip antennas have a small size but their gain is insufficient for most applications. Therefore, a ring-shaped compact microstrip reflectarray with microstrip antenna feed has been proposed. Different configurations, namely, 1 × 3, 3 × 1, plus-shaped and 3 × 3 have been analyzed. The 3 × 3 configuration yields an optimum gain of 10. 8 dBi and a narrow beamwidth of...

متن کاملAnalysis of a Microstrip Reflectarray Antenna for Microspacecraft Applications
A microstrip reflectarray is a flat reflector antenna that can be mounted conformally onto a spacecraft’s outside structure without consuming a significant amount of spacecraft volume and mass. For large apertures (2 m or larger), the antenna’s reflecting surface, being flat, can be more easily and reliably deployed than a curved parabolic reflector. This article presents the study results on a...
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...
