Abstract
In one embodiment, an apparatus includes a printed circuit board, a via-stub resonator formed in the printed circuit board, a plurality of vias surrounding the via-stub resonator, and a microstrip connected to the via-stub resonator for use in measuring an insertion loss to provide a resonance frequency. The via-stub resonator is designed to reproduce a dielectric constant value of a known material in a simulation. A via dielectric constant in an x and y plane is calculated based on the resonance frequency. A method for measuring the via dielectric constant using the via-stub resonator is also disclosed herein.
