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.

Circularly Polarized Folded Reflectarray Antenna With Improved Aperture Efficiency

IEEE Open Journal of Antennas and Propagation
This paper presents a method for improving the aperture efficiency of circularly polarized folded reflectarray (CPFRA) antennas. The reflection-phase distribution of the circular polarization selective surface (CPSS) constituting the CPFRA antenna is ...

Design of Wideband Reflectarray and Transmitarray Antennas With Low Sidelobe and Cross-Polarization Levels Using a Multifunctional Ultrathin Metasurface

IEEE Open Journal of Antennas and Propagation
Ensuring a low cross-polarization level (CPL) is imperative in the design of antennas with a low sidelobe level (SLL). This paper introduces an innovative approach for designing wideband, high-gain, low-sidelobe, and low-cross-polarization reflectarray ...
