Frontiers in Reflectarray Design
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019The design of wide reflectarray antennas (RA) featuring complex unit cells through a scalable, efficient, and effective approach based on the System-by-Design (SbD) paradigm is investigated in this work. Towards this end, the customization of the SbD loop to the RA synthesis problem is described, and the integration of advanced micro-scale modeling ...

Optimization of a Gangbuster Reflectarray Antenna
2005 IEEE Antennas and Propagation Society International Symposium, 2005In this paper we discuss the optimization of the design, carried out through a pseudo-random optimization algorithm, of a gangbuster reflectarray antenna. The variation of reflection coefficient phase on the reflectarray surface is achieved by varying the length of the local wires in the gangbuster surface. For the optimization, a genetic algorithm has

A Low-RCS Circularly Polarized Reflectarray Antenna With a Linearly Polarized Feed
IEEE Transactions on Antennas and Propagation, 2023A low-radar cross Section (RCS) circularly polarized (CP) reflectarray antenna with a linearly polarized (LP) feed is designed. The out-of-band RCS of the reflectarray for both the TE and TM polarized incident waves is reduced by replacing its ground ...
