Abstract

A variety of low dielectric constant composites have been made into films and characterized. These composites were blends of liquid crystalline polymers (LCPs), hollow glass spheres (HGS) and polytetrafluoroethylene (PTFE). By adjusting the percentage compositions of the various components of the composites, the dielectric constant could be adjusted in the range 2.4 to 3.4. Measurement of the dielectric constant by Time Domain Reflectometry (TDR) and Frequency Domain Reflectometry (FDR) are discussed. Dielectric anisotropy is also discussed. The experimentally observed results are compared with those derived theoretically.
