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.
