We present a thin and flexible broadband polarizer‐absorber concept based on a multi‐layered anisotropic arrangement of carbon nanotubes (CNT) and polymer films. The anisotropic layers consist of CNT striplines deposited over a prepared polycarbonate surface. Stacks of the patterned composites organized in gradient of layer conductivity are very effective for polarization‐sensitive absorption of incident microwaves. This specific arrangement drastically decreases undesired reflection and yields an average degree of polarization of 0.46 for a millimeter‐thick multilayer over the 8–67 GHz range. © 2017 Wiley Periodicals, Inc.
