A Double-layer Circularly Polarized Lens Array Element Based on Angular Rotation Techniques: Circularly Polarized Lens Array Element

Abstract

In this paper, we propose a double-layer circularly polarized (CP) lens array element. The proposed element has an overall thickness of only $0.22\lambda_{0}$, which offers the advantages of light weight, easy fabrication and low cost compared to conventional two-dimensional (2D) elements. The element's transmission coefficient is simulated and the results indicate that the element manifests a high transmission rate and good CP performance.
