Rogers Corporation has introduced a new series of high impedance laminates. The MAGTREX 555 (first product in this series) 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 Corporation’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.
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.
