Novel Photonically-Controlled Reflectarray Antenna

IEEE Transactions on Antennas and Propagation, 2006
A novel method for generating a reconfigurable reflectarray based on the creation of photoinduced plasma inside the semiconductor substrate of a reflectarray is presented in this paper. A reflectarray antenna prototype is fabricated and measured to demonstrate the validity of the design methodology.

A six-band reflectarray antenna

2009 IEEE Antennas and Propagation Society International Symposium, 2009
This paper presents a reflectarray configuration which supports the operation of six frequency bands. The proposed reflectarray has two substrate layers and each layer accommodates array elements of three frequency bands. Reflection phase curves of the array elements of different frequency bands are simulated.

Investigation of slot reflectarray antennas

2018 Moscow Workshop on Electronic and Networking Technologies (MWENT), 2018
Research 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.

K-band slot reflectarray antennas

2018 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2018
The paper studies metal-only slot reflectarray antennas characteristics. All arrays under study are designed to be manufactured with laser-cutting technique. Bandwidth dependence on geometry parameters is considered for the case of single-layer linear-polarization antenna. The analysis is based on both full-wave simulation and a solution of an integral-

UWB Reflectarray Antenna for chipless RFID applications

2014 31st National Radio Science Conference (NRSC), 2014
The main limitation of any chipless Radio Frequency Identification (RFID) system is the very short reading range. In this paper, we propose an Ultra Wideband (UWB) Reflectarray Antenna (RA) system with 2.2 GHz bandwidth centered at 6 GHz for the reader of chipless RFID applications.
