Data transmission speed in electronic systems has increased steadily as a result of the development of information technologies. The insulation materials used in these systems require a very low dielectric constant (εr) and a similarly low dielectric loss (tanδ). Such materials have been developed for satellite communications and high grade computer systems, however, operating speeds in popular electronics such as mobile or personal systems will also exceed 1GHz in the near future. When that happens, cost will become an even more important factor in the selection of high-performance insulation materials. Dicyclopentadiene polymer (Metathene) has a εr of 2.51 and a tan δ of 0.0029 at 1GHz. Moreover, Metathene containing air (63% air by volume) measures as low as 1.57 for εr and 0.001 for tan δ at the same frequency. This paper presents an assessment of the appropriateness of Metathene for high-frequency applications.
