RO4500 high frequency laminates are fully compatible with conventional FR-4 and high temperature lead free solder processing. These laminates do not require special treatment needed on traditional PTFE-based laminates for plated through-hole preparation. The resin systems of RO4500 dielectric materials provide the necessary properties for ideal antenna performance. This product series is an affordable alternative to more conventional antenna technologies, thus allowing designers to maximize the price and performance of their antennas.


  • Dielectric constant (Dk) range of 3.3 to 3.5 +/- 0.08
  • Dissipation factor range of 0.0020 to 0.0037
  • Available in large panel sizes


  • Excellent passive inter-modulation (PIM) with LoPro® copper foil
  • Improved mechanical rigidity over PTFE
  • CTE similar to that of copper, reducing stress in PCB antenna
