|Download Microwave Wire Grid Polarizers Datasheet (PDF, 484 KB)|
For microwave range we produce wire grid polarizers intended to polarize radiation in between 2-3 GHz and 300 GHz. They are made of 20 μm thick parallel tungsten wires mounted in a holder with no substrate.
• Antenna engineering.
• Can withstand high energies of incident radiation;
• Due to no substrate provide high transmissivity of desired polarization;
• Provide high degree of polarization;
• Made of tungsten wires;
• Mounted in holders (protective rings marked with wire direction).
The advantages of wire grid polarizers over polypropylene grid polarizers:
• Better transmission of desired polarization due to no substrate;
• Can withstand high-intensity radiation.
