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

A Reconfigurable Reflectarray Antenna Unit Cell

2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI), 2022
This 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.

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
