Low profile fractured-reflect-disk to generate OAM vortex beam in X-band

This work proposes and realises using EM simulation a low profile Fractured Reflect Disk to produce efficient Orbital Angular Momentum (OAM) vortex beam in X-Band. It examines a unit cell with appropriate reflection efficiency and phase response. Then assembly of unit cells as per their phase response generates vortex beam. In the simulation of the Fractured-Reflect-Disk, a microstrip antenna acts as the feeding element. Simulated results indicate the possible realisation of highly efficient OAM vortex beam which may find effective application in wireless communication.
