Abstract
An antenna system can impart orbital angular momentum (OAM) to an incident electromagnetic (EM) signal from a feed antenna. The antenna system can include a partial OAM antenna with a reflective surface that has only part of a full OAM shaped surface. The antenna system can thus reflect the incident EM signal as a partial OAM beam rather than a full OAM beam.
