“…Leaky wave antennas are capable of producing a sequential phase delay [44], [45] which can be used to generate OAM beam on a circular guiding structure. Recently, a few leaky-wave system have been demonstrated in the literature to generate a fixed OAM beam with frequency-dependent beam scanning capabilities [46], [47].…”

Orbital angular momentum (OAM) beams, also known as vortex beams, have gained a significant attraction in the past decade. Their ability to offer an infinite number of modes (theoretically) opens doors to develop new high datarate and secure communication system. In this paper, we present the general theory of OAM beams and give a brief overview of different techniques presented in the literature to achieve such beams with high order mode purity.
