Abstract
Polarization converters play an important role in modern communication systems, but their wide and multiple band operation to facilitate volume and size reduction is quite challenging. In this letter, a dual-band linear polarization (LP) to circular polarization (CP) converter is presented using a novel design procedure based on geometric parameters optimization of a meta-array. For dual-band operation, the concept of mutual interaction of two distinct resonators is used. Step-by-step design procedure is proposed and an example is presented to convert incident x ( y ) polarization into transmitted left-hand circular polarized (LH-CP) [right-hand circular polarized (RH-CP)] in Ku band (15.15–19.5 GHz) and RHCP (LHCP) in Ka -band (33.1–39.05 GHz). After performing model-based theoretical paradigm analysis, and full-wave simulation and optimization, the converter is fabricated and the measurements are performed with a vector network analyzer. The measured results, close to simulation results, depict the validity and reliability of the design. The proposed meta-array is ultrathin, wideband, and polarization diverse, which is very suitable for wide range of applications including millimeter-wave-communication.
