Abstract

A transmission polarizer is described that is based on an anisotropic impedance surfaces to convert the incident linearly polarized wave to a circularly polarized one. The polarizer is based on a frequency selective surface (FSS) with two concentric rings having cuts at different orientations/angles. By virtue of anisotropy it is possible to independently control the transmission characteristics of two orthogonal linearly polarized incident plane waves and therefore to achieve polarization conversion in the transmission direction. A unit cell approach with periodic boundary conditions is considered in the design environment; this unit cell incorporates the two concentric rings. The proposed topology supports in achieving dual-band polarization conversion, which has advantages over previously reported designs. The polarizer works at 27.2 GHz and 39.5 GHz and provides the required 90 phase difference between the two orthogonal components, which are equal in magnitude. The structure provides around 99% polarization purity at resonance. The linear performance of this new structure is described through results of numerical simulations.
