Characterization of the Dielectric Properties of Commercially Available Low-loss UV-curable Resins from 60 GHz to 90 GHz
conference paper
In this paper, two important dielectric properties,
the relative permittivity and the loss tangent of a new
commercially available UV-curable SLA resin sample are
determined. The characterization of the dielectric material is
performed in the millimetre-wave range using an open-cavity
Fabry-Perot resonator. According to the manufacturer’s data ´
sheet, this ultra low-loss photoresist material, optimised for
advanced electronic applications, has a relative permittivity of 2.6
and a loss tangent of 0.003, both at 10 GHz. First, the accuracy
of the Fabry-Perot open-cavity resonator was determined using ´
a reference material called Rexolite. Then, the new dielectric
material was measured in a frequency band from 60 GHz to 90
GHz. The results show that the new commercial resin sample
has a relative permittivity of 2.59 and a loss tangent of 0.0031 at
71.8 GHz.
