چکیده
The utilization of orbital angular momentum (OAM) presents an effective approach that enables the simultaneous use of multiple channels on a single frequency. Compared with conventional OAM carrier waves—whose three-dimensional radiation pattern resembles a cone with a hollow region at its center—the planar-spiral orbital angular momentum (PSOAM) carrier propagates transversely, making it more suitable for various practical applications. For the first time, the generation of PSOAM waves using a uniform circular array of microstrip antennas based on electromagnetic metamaterials has resulted in a phase pattern distinct from the conventional OAM theory. This study demonstrates that incorporating metamaterials into the antenna array structure facilitates the generation of higher-order OAM modes with fewer elements than conventional antennas. Simulation results indicate that the proposed array achieves approximately a 27% reduction in the number of antenna elements. Furthermore, the introduced antenna exhibits a wide relative bandwidth of 1.93.
