Orbital angular momentum (OAM), which characterizes the helical phase pattern of optical beams, has recently attracted enormous interest due to its potential applications in different practice areas. Here we propose an antenna design for generating multiple beams carrying OAM with different topological states at the same frequency. The numerical fullwave simulation is performed for an actual size OAM generator using the ANSYS HFSS electromagnetic solver, and an antenna prototype operating in the microwave band is fabricated and tested. Obtained results prove that the proposed antenna can be used as a compact and low-cost generator of multiple beams with different OAM states.

Abstract

Orbital angular momentum (OAM), which characterizes the helical phase pattern of optical beams, has recently attracted enormous interest due to its potential applications in different practice areas. Here we propose an antenna design for generating multiple beams carrying OAM with different topological states at the same frequency. The numerical fullwave simulation is performed for an actual size OAM generator using the ANSYS HFSS electromagnetic solver, and an antenna prototype operating in the microwave band is fabricated and tested. Obtained results prove that the proposed antenna can be used as a compact and low-cost generator of multiple beams with different OAM states.
