Kurzfassung deutsch:
An accurate characterization of microwave mate-
rials is essential for reliable high frequency circuit design.
This paper presents a measurement setup, which enables a
quick and accurate determination of the relative permittivity
of dielectric bulk materials up to 110 GHz. A ring-resonator
is manufactured on a well characterized substrate dealing as
reference resonator. The Material Under Test (MUT) is placed
on top of the ring, which increases the effective permittivity and
therefore introduces a shift of the resonance frequency of the
resonator. Electromagnetic field simulations with different heights
and relative permittivities of the MUT provide a lookup table
for the measured resonance frequencies. The functionality of the
proposed measurement setup is validated by measurement results
of different MUTs.
