Abstract

This paper proposes a novel transmitarray antenna which can achieve high gain and

dual-polarized microstrip antennas are employed as the unit cells, which are connected using metalized

orthogonal polarizations. Due to high isolation between the two orthogonal polarizations, dual-mode

respectively. The approach for generating OAM beams is explained. To verify this concept, one

results demonstrate that the both 0 and +1 mode OAM beams can be generated successfully, and the

of transmitarray, the proposed +1 mode OAM beam has stable performance at a long propagation

Meanwhile, a narrow divergence angle of +/-5 o is obtained in +1 mode OAM beam. Compared to other

angle?low cost, planar structure and the capability of producing dual-mode OAM beams.
