MAGTREX® 555 materials are constructed from a proprietary, low loss, high resistivity ceramic filler and a high temperature thermoplastic matrix. This yields a system which is conformable, PCB processable, and mechanically and electrically stable.  \nMAGTREX® 555 materials offer a miniaturization factor comparable to a material with a dielectric constant of 30, with an intrinsic impedance comparable to a material with dielectric constant of 1. This makes the material ideal for miniaturizing antennas below 500 MHz in operating frequency.  \nWhen used as part of an antenna design, MAGTREX® 555 materials offer designers the ability to produce electrically small antennas with bandwidth and efficiencies not previously possible.  \nMAGTREX® 555 materials are available with copper, for use as a laminate material, or without copper for use as a loading element for cavity backed antennas.  \nWhen ordering MAGTREX® 555 materials, it is important to specify laminate thickness and whether copper is required, and if so, the copper thickness.  \nData Sheet  \nFeatures and Benefits:  \nMatched permeability and permittivity  with high miniaturization factor √ er µr  \n• Substrate impedance matched to air  \n• Antenna miniaturization with improved bandwidth  \nHigh temperature thermoplastic composite laminate with low moisture absorption  \n• Environmentally stable electrical performance  \n• Flexible and mechanically robust  \nLow dielectric and magnetic loss below 500 MHz  \n• High antenna efficiency  \nTypical Applications:  \n• Low profile VHF/UHF antennas  \n• Electrically small VHF / UHF antennas  \n• VHF magnetic components (eg.
