Abstract

In this article, a transformation optics (TO)-based orbital angular momentum antenna is presented. By applying the coordinate transformation, the electromagnetic wave can be arbitrarily manipulated. A TO-based horn antenna working at 5 GHz is designed. The simulation results show that by adopting the proposed TO-based filling, the main lobe angle is reduced by 4° and the maximum gain is improved by 6.4 dB. At the same time, the proposed horn antenna has high aperture efficiency.
