Abstract
The orbital angular momentum (OAM) beam can be used to significantly increase the communication capacity. In this paper, a reflectarray antenna is proposed and demonstrated for generating arbitrary OAM beams. A new dual-resonance dipole element is employed to implement the conversion between the incident spherical wave and the reflected OAM wave. Besides, this element can provide very good polarization separation and wide phase coverage. Thus, the OAM multiplexing can be achieved in a compact configuration by using independent feeders. As an example, four independent OAM modes, i.e., l=±1 and l=±2, are generated by a Ka-band reflectarray antenna.
