A multilayer conformal dual-polarized antenna (ML-CDPA) with bending performance in all directions is presented. The antenna consists of a supporting ground plane and four identical radiating elements. Each element comprises two semi-elliptical-shaped polyimide films with patches stacked together to achieve 20% bandwidth.
The ML-CDPA is designed for L-band and tested for the flat case as well as conformed to a cylinder with 200 mm, 160 mm, 150 mm, 100 mm, and 80 mm radius.
