Investigation of slot reflectarray antennas
2018 Moscow Workshop on Electronic and Networking Technologies (MWENT), 2018Research results of slot metal-only reflectarray antennas are presented in this paper. The analysis is based on both full-wave and unit-cell simulation. The solution is based on the Method of Moments that is applied to integral equations in terms of magnetic-current distribution functions. Reflection phase of one- and two-layer unit cell is considered.

We present a wideband reflectarray antenna with electronic beam-steering capability. The beam-steerable reflectarray uses an electronically reconfigurable polarization-rotating unit cell (PRUC) that acts as a wideband 1 bit phase shifter.

Computationally Efficient Surrogate-Assisted Design of Pyramidal-Shaped 3-D Reflectarray Antennas
IEEE Transactions on Antennas and Propagation, 2022Reflectarrays (RAs) have been attracting considerable interest in recent years due to their appealing features, in particular, the possibility of realizing pencil-beam radiation patterns, as in the phased arrays, but without the necessity of ...

Hybrid Polarization-Phase Tuning Methodology for Reflectarray Antennas
IEEE Transactions on Antennas and Propagation, 2021A hybrid polarization-phase tuning methodology is presented for reflectarray antenna designs. First, three representative phasing approaches for reflectarray designs are briefly reviewed, and it is pointed out that when the polarization conversion is ...

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.

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 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

Circular polarized reflectarray antenna
20th Iranian Conference on Electrical Engineering (ICEE2012), 2012In this paper, aperture coupled dielectric resonator antenna loaded with rotated strip, is used as a CP element for reflectarray antenna. Phase variations are obtained by a symmetric change in the length of the stub. The effect of the various parameters of the structure on the slope of the phase curve is studied. Simulations are carried out with Ansoft
