Recent investigations demonstrated that porosification
offers the possibility of high quality antenna integration on
LTCC by local reduction of the relative permittivity. In order
to take advantage of this technology, further research for the
deposition of conductors on porosified areas has to be done.
Since the near-surface material removal is strong, conductors are
expected to penetrate substantially into the porosified substrate.
In this paper a new, randomized structural modeling technique
of porosified LTCC is presented, which is based on scanning electron
microscope imaging. Finite 3D field simulations, performed
with this model, show the electromagnetic effects of different
vertical microstrip positions on the effective permittivity and the
corresponding scattering parameters.
