Rogers Corp. is pleased to introduce MAGTREX™ 555 Laminates, the first product in a new platform of high impedance laminates featuring a high permeability and permittivity. These high impedance laminates enable antenna designers to expand the trade-space of their antenna design enabling up to a factor of six reduction in size with minimal impact on bandwidth, up to a factor of six increase in bandwidth with similar size, or a design optimum in between.
MAGTREX 555 high impedance laminates 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 Corp.’s popular RT/duroid® laminates.
MAGTREX 555 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.
