Wide-Band Linear Polarizer Based on a Frequency Selective Surface

Abstract

A Frequency Selective Surface built on an FR4 substrate, that exhibits linear polarized transmission field for a generally polarized incident electromagnetic waves in the frequency range below 10 GHz is introduced. Outgoing waves are linearly polarized on two orthogonal directions, in two different frequency bands. The operation of the proposed structure is wide-band, the two bands intersecting at −10 dB. A parametric study demonstrates flexibility in design, also the structure being tested for oblique incidence
