    Quarter Wave Plates (QWP)

    • Working bandwidth from DC up to 1.5 THz
    • Very low transmission loss
    • Rotating frame with angular scale
    • Ultra-low loss and flexible substrate material

    Anteral’s Quarter Wave Plates (QWP) consist of a patterned Cu-Au micro grid array of strips in the topside and a continuous conductor in the backside. The micro grid array is patterned via photolithography process on very thin (135 µm), flexible and ultra-low loss substrate for THz frequencies with low dielectric constant. The QWP is designed to generate a reflected circularly polarized wave when a linearly polarized wave impinges over its surface. QWP are mounted with protection layers made of a high-performance polymethacrylimide foam without degradation of the quality. Anteral also offers custom designs of QWPs. Contact us for more information.

    The QWPs can be used from DC up to 1.5 THz systems for generation of circular polarization.

    Anteral also offers their Wire Gird Polarizers for enhancement of the polarization sensitivity or beam splitting.
