The dielectric constant and loss factor of Rogers ro4835 and Rogers ro4350 are basically the same. The difference is that the plate Rogers ro4835 adds antioxidant filler on the basis of Rogers ro4350, and has passed the test of automobile safety regulations, which is suitable for the design of automotive anti-collision radar antenna.
Rogers PCB RO4835 material
Rogers RO4835 PCB material offer high stability at elevated temperatures and significant oxidation resistance.
RO4835 laminates are a low loss material that offer low cost circuit fabrication, compatible with standard epoxy/glass (FR-4) processes. These laminates are available with Rogers proprietary LoPro Reverse treated copper foil, ideal for applications requiring low insertion loss.
