Beam-Scanning Reflectarray Based on a Single Varactor-Tuned Element
International Journal of Antennas and Propagation, 2012 A single varactor-tuned element is investigated as effective solution for the realization of reconfigurable reflectarray antennas. The proposed configuration is successfully implemented for the design of an X-band reflectarray prototype of 3×15 radiators.

A High-Power Microwave Reflectarray Antenna Based on Perforated Dielectric Substrate
Advanced Electromagnetics, 2019 A high power microwave antenna based on the reflectarray concept is designed and investigated in this paper. The reflectarray aperture is directly driven by an azimuthally symmetric mode and a directional boresight beam is realized through azimuthally ...

Microstrip reflectarray antenna with offset feed
Electronics Letters, 1992 The authors derive and verify the concept of antenna focusing by a planar 'microstrip reflectarray' antenna. Experimental results from schematically distributed patch radiators with microstrip delay lines are consistent with the simulation results. The advantages and disadvantages of such an antenna are described.

Reflectarray antennas for terahertz communications
, 2012 Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are demonstrated for operation at terahertz frequencies. Based on the relation between the patch size and the reflection phase, a progressive phase distribution is implemented on the patch array to create a reflector able to deflect an incident beam towards a ...

Millimetre wave reflectarray antenna unit cell measurements
Loughborough Antennas & Propagation Conference (LAPC 2017), 2017 Reflectarray antennas are a potential candidate solution to realize high gains at millimetre waves (mm-waves). A reflectarray contains a large number of spatially illuminated unit cells. The performance of a good reflectarray design is manifested by the behaviour of its comprising unit cells.
