Abstract
A microstrip ring resonator structure is used to determine the dielectric constant and dissipation factor of FR-4 type printed circuit board material. The article presents essential information on the microstrip ring resonator measurement method, characteristics of the microstrip line losses, and dielectric constant and dissipation factor calculation techniques. Based on the presented information, the dielectric properties of high loss printed circuit board materials can be determined for a wide frequency band.
