Abstract

The permittivity and loss angle of disc-shaped polymer specimens were measured by using three Split-Post Dielectric Resonators (9.5 GHz, 25 GHz & 34 GHz), a plano-concave open resonator (36 GHz), a bi-concave open resonator (20 GHz to 50 GHz), a helical cavity (10 GHz), and two free-space Gaussian-beam transmission systems (22 - 33 GHz & 60 - 90 GHz). The measured materials were PMMA, polycarbonate, THV 500GZ fluoropolymer, and two grades of PTFE. The work supports the need for materials for manufacture of components for 5G applications.
