摘      要：This article proposes a new kind of microstrip reflectarray antenna,of which the polarization could be reconfigured among all the polarization states instead of some fixed states in a dual-or multi-polarized *** mechanism for polarized variability is so simple that only mechanical rotation is *** analysis shows that the reflected polarization covers all states and that the dual-or multi-layered unit structure sandwiched with air-gaps can broaden the bandwidth ***,it is demonstrated that adopting more elements can enhance antenna *** these advantageous features,this kind of antenna has the potential significance for engineering applications in radar,communication,*** this article,a complete theoretical analysis as well as a specific design sample is given to verify this method.
