%X An efficient numerical implementation of the Integral Equation technique (IE) has
been developed for the analysis of the electrical characteristics of finite microstrip structures.
The technique formulates a volume version of the IE for the finite dielectric objects, and a
standard surface IE technique for the metallic areas. The system of integral equations formu-
lated are solved with special numerical techniques described in this paper. The input impedances
of several microstrip antennas have been computed, showing good agreement with respect mea-
surements. The technique has shown to be accurate even for complex geometries containing
several stacked dielectric layers. The radiation patterns of the structures have also been com-
puted, and measured results from real manufactured hardware confirm that backside radiation
and secondary lobes are accurately predicted by the theoretical model. The paper also discuss
a suitable excitation model for finite size ground planes, and investigates the possibilities for
an independent meshing of the metallic areas and the dielectric objects inside a given geom-
etry. The practical value of the approach derived is that microstrip circuits can be designed
minimizing the volume and size of the dielectric substrates.
