Dielectric Constant Measurement Using Microstrip Ring Resonator Method

(1/1)

neilhao:
In this article, a HTCC substrate is measured by using the Ring Resonator method.

The Ring Resonator method has following advantages [2]:
1. A closed ring with no gaps eliminates much of the fringe effect.
2. Resonator rings ensure minimal or negligible loss by radiation, so that Er can be calculated more accurately.
3. The results refer to very narrow band ranges/widths (resonance); this avoids issues connected to spurious modes.
