Frontiers in Reflectarray Design

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
The 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, 2005
In 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

The reflectarray antenna

IEEE Transactions on Antennas and Propagation, 1963
A class of antennas that utilizes arrays of elementary antennas as reflecting surfaces has been investigated. An antenna of this type is here called a Reflectarray. It has been found that the Reflectarray combines much of the simplicity of the reflector-type antenna with the performance versatility of the array type. The reflecting surfaces employed in

A Reconfigurable Origami Reflectarray

2020 14th European Conference on Antennas and Propagation (EuCAP), 2020
This paper presents a novel Miura-Ori origami reflectarray unit-cell. This origami inspired unit-cell allows efficient folding\unfolding, high packing efficiency, easy deployment and frequency reconfigurable behavior. The unitcell is composed of 4 parallelogram patches that can achieve 560° phase shift.

Genetic optimization of microstrip reflectarrays

IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2005
Printed reflectarrays try to combine the advantages of both reflectors and printed arrays (see e.g. [l]) and consist in arrays of printed patches, illuminated by a primary feed horn, that re-radiate the illuminating power back into the space. Since the elements have different positions, the field that propagates from the feed to the patches covers ...

Printed millimeter-wave reflectarrays

Annales Des Télécommunications, 2001
Des structures periodiques et quasi-periodiques, imprimees sur un substrat dielectrique peuvent etre employees pour commander les proprietes de reflexion et de transmission des ondes incidentes en fonction de la structure geometrique. Ceci peut etre realise pratiquement independamment pour les deux polarisations.

Frequency Tunable Graphene Metamaterial Reflectarray

Wireless Personal Communications, 2017
In this paper, the radiation characteristics of frequency tunable graphene based metamaterial reflectarray have been investigated. The unit-cell consists of graphene two gaps split-ring-resonator (SRR) printed on a thick SiO2 substrate. The metamaterial parameters of the unit-cell have been calculated at different graphene chemical potentials and ...

1-bit Reflectarray Element Based on a Single Switch for Reconfigurable Reflectarrays

2019 Antennas Design and Measurement International Conference (ADMInC), 2019
In this paper, we present a new reconfigurable element using p-i-n diode for reconfigurable reflectarray antennas. The element cell is realized using a single substrate, a ground plane and only a single p-i-n diode embedded in the element, hence very low complexity.

Reflectarray antenna design

2017 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2017
The process of reflectarray antenna design can be usually carried out into two separate steps: element design and aperture phase distribution design. In the step of element design, reflectarray elements need to be devised based on the requirements of phase range, element bandwidth, polarization and so on.

Microstrip patches for a reflectarray

IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003
Microstrip patch element geometry is indeed an important factor in the design of a microstrip reflectarray. In essence, each of these perfectly conductive elements creates a minuscule correction to the reflection phase of the scattered field so that a phase coherent main beam is constructed.
