The unique properties of proposed radiator are: (i) dual band circularly polarized aerial is designed in THz regime; (ii) application of graphene layer over ceramic makes the radiator reconfigurable in terms of both frequency range and axial ratio; and (iii) asymmetrical dumbbell shape helps to create dual radiating mode i.e. HEM 11δ and HEM 12δ mode. For verification purpose, optimized outcome obtain from Ansys HFSS is compared with CST-MWS. There is good agreement between them. The designed radiator works good in between 2.4 THz-3.0 THz and 4.4 THz-5.15 THz. The value of axial ratio below 3-dB is achieved in between 2.6 THz- 2.8 THz and 4.6 THz-4.8 THz respectively. Broadsided radiation pattern and good gain characteristics create the designed aerial suitable for different wireless applications in optical domain.
