andlowdielectric constant substrate materialDescription
The Polarizers consist of a simple patterned Cr-Cu-Au micro grid array of strips. The micro grid array ispatterned via photolithography process on a very thin (100 µm) and ultra-low loss substrate for THz
frequencies with low dielectric constant. The electric field is transmitted if polarized perpendicularly andreflected if polarized parallel to the grid array. Anteral offers two different designs of General Purpose
Polarizers, one for MmW and other of superior performance for THz frequencies.

Applications
The Polarizers can be used in MmW and THz systems for enhancement of the polarization sensitivity, beam
splitting and generation of circular polarization.
Circular polarization is generated for 45 degrees incidence by means of selecting the appropriate dielectric
thickness and backing the polarizer with a metal plate. Several thicknesses of the dielectric material can beselected for creating circular polarization between 50 GHz and 750 GHz.

Additional Notes
Polarizers are provided in regular diameters of 50 mm and 25 mm. They are mounted in rotating frameswith angular scale of step equal to 1 degree and with ISO M4x0.7 connection.
Different sizes (up to 70 mm) and geometries (square and circular) can be provided according to customer
requirements. Ad-hoc frames for special purposes are also offered.
Polarizers are mounted with protection layers made of high-performance polymethacrylimide foam without
degradation of the quality.
The performance of all polarizers is checked before delivery.
Extended performance datasheet is available if customer requires. Ask for more information.
