Abstract

A new broadband CP reflectarray element based on split-ring-related structure is presented in this paper, which exhibits a bandwidth from 10.1 GHz to 18.3 GHz. In order to see the physical insight behind the multi-band and broadband property of the circular polarized (CP) element, the scattering mechanism of the element is investigated, and intuitive explanations are given. The results in this paper are also helpful to understand the broadband mechanism of the CP relfectarray element proposed in recent literatures.
