A dual orbital angular momentum (OAM) mode antenna with l=0 and l=4 mode wave is presented. The proposed antenna employs a transmitarray and a reflectarray and uses a dual-polarization conical horn as the feed. By using two orthogonal linear polarization waves as excitations, the antenna can generate a pencil beam and an OAM beam, respectively.
