logo-evonik With its extremely low dielectric constants and particularly favorable transmission properties in the high frequency region, ROHACELL® HF has been specially designed for antenna applications.

Applications range from miniature antennas in cell phones to large fixed ship-based and stationary antenna structures. Other advantages of ROHACELL® HF in such applications are its extremely fine cell structure that ensures minimal resin uptake, and problem-free compatibility with metallic facing materials due to the absence of corrosive effects. ROHACELL® HF can also be used in radomes and mammography plates.

Fine-cell materials can be processed by hand lay-up, pre-preg, or vacuum infusion techniques at pressures up to 0.3 MPa and temperatures up to 130°C. Cirexx commonly uses the Rohacell material in place of an air spacer between radomes and elements in antenna application by applying the Rohacell to an antenna Printed Circuit board.
