Abstract :
A design procedure for a circularly polarised (CP) reflectarray with linearly polarised feed is presented. It is validated by simulation and experiment results that exhibit the cross-polar level of -20 dB at the designed frequency, and -10 dB in 14% bandwidth. This type of CP reflectarray can be used as a good substitution for those with a CP feed.
