This paper presents a measurement technique for extracting complex permittivity in the range of 1-30 GHz from coupons manufactured on printed wiring boards (PWBs), with the goal of obtaining causal, frequency-dependent dielectric properties needed for high-speed transmission line modeling. This measurement method employs resonant-plate coupon structures and an analytic solution to the Helmholtz equation to calculate the relative permittivity (år) and the loss tangent (ä) across a continuous range of frequencies. Simulations from a 3D structure simulator help decompose the total loss tangent into dielectric, radiation, and conduction loss components. Hardware validation measurements are also presented.
