Abstract
In this paper, reconfigurable polarization converter from linear polarization to circular polarization is designed based on graphene artificial magnetic conductor surface. The reconfigurable conductivity of the graphene material allows the change of electromagnetic wave polarization left-hand and right-hand circular polarization (CP) through electrical DC biasing. The gain enhancement of V-shaped dipole antenna is achieved by backing it with AMC array. The antenna gain is increased up to 4.7 dBi with AMC ground plane. Different AMC ground plane sizes and their effect on polarization conversion are investigated. The polarization conversion bandwidth is 19.44% for 7x7 AMC array. Full-wave analysis is used to model the array structure.
