Abstract
In this paper, we investigate a novel efficient metasurface-based wideband cross-polarization converter. The device rotates the y-polarized electromagnetic (EM) wave into an x-polarized EM-wave for a wide range of wavelengths (9.8 GHz–18.9 GHz) and vice versa. The unit cell of the proposed converter is very small and consists of four metal/dielectric layers. The asymmetric resonators represent a solid base to allow higher conversion efficiencies, while the slightly varying magnetic and electric resonances between neighboring layers produce a broad operating frequency range. Furthermore, only additive manufacturing technology was used, which offers a low-cost and simple solution to produce the complicated multilayer device. Both measured and simulated results are in good agreement confirming the excellent performance. This study can help both the affordable design and fabrication of multilayer wideband polarization converters in the future.
