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

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.

Design of Wideband Reflectarray Antennas
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020The method providing bandwidth increasing of reflect array antennas is proposed. The main idea of this method is to compensate phase errors by means of the spatial separation of layers with reflective elements. A full-metal reflectarray antenna has been designed with the use of the proposed method, manufactured and tested.

Microstrip Reflectarray Antenna Program.
1977Abstract : Results of a study to determine the feasibility and design limitations of a microstrip reflectarray antenna are presented. This antenna, which has been proposed as a means to provide potential low-cost corporate-fed phased arrays, utilizes microwave integrated circuit techniques to integrate the radiating element, phase-shifter components ...

A six-band reflectarray antenna
2009 IEEE Antennas and Propagation Society International Symposium, 2009This 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.
