MAGTREX 555 Image

The MAGTREX 555 from Rogers are high impedance laminates that enable antenna designers to miniaturize VHF and UHF antennas while maintaining the bandwidth achieved in a larger design. These laminates feature a closely matched X/Y axis permeability and permittivity of six and six and a half respectively, along with low magnetic and dielectric loss below 500 MHz. MAGTREX 555 laminates are based on a ceramic / PTFE composite system, manufactured in a process similar to Rogers Corporation&rsquos popular RT/duroid® laminates.

These high impedance laminates feature a low X, Y, Z CTE closely matched to copper for thermal reliability and are available in thicknesses from 20 to 250 mils. They are offered with or without copper cladding.
