Analysis of dual-reflector antennas with a reflectarray as subreflector [PDF]
In this paper, a modular technique is described for the analysis of dual-reflector antennas using a reflectarray as a subreflector. An antenna configuration based on a sub-reflectarray and a parabolic main reflector provides better bandwidth than a ...

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 Reconfigurable Reflectarray Antenna Unit Cell
2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI), 2022This paper focuses on the application of a tunable square microstrip unit cell to the design of a wideband reconfigurable reflectarray antenna. The design utilizes the concept of varactor-loaded stubs to provide a wide tuning range with sufficient phase range.

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

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.

Broadband Optimization of Reflectarray Antennas
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019This paper presents the broadband design method for reflectarray (RA) antennas. The differential evolution (DE) algorithm has been applied to balance the spatial phase delay errors in the whole work band. A RA antenna consisted of split ring elements has been proposed to validate the method.

An Amplifying Reconfigurable Reflectarray Antenna
IEEE Transactions on Antennas and Propagation, 2012Electronically tunable reflectarrays and amplifying reflectarrays have attracted considerable research in recent years, however, little work has been done to combine these two features simultaneously in a single design. This paper focuses on the design of such a reflectarray, which can be used as a high gain, reconfigurable transmitting antenna for ...
