Topological Design for Antenna Pattern Shaping

Some recent works have demonstrated that phase singularities of vortex fields can find different applications at microwave frequencies. In particular, it has been shown that topological properties of phase singularity points can be used to design patch antennas with reconfigurable radiation characteristics. The aim of this contribution is to generalize the aforementioned approach and, thus, to present a general design tool for antenna pattern shaping based on topological properties of vortex modes.
