Abstract
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. The numerical implementation combines
rooftop basis and testing functions for the conducting metallic
areas, and two different choices for the dielectric objects. The first
is based on a classical approach, combining pulse basis functions
and deltas for testing. The second is a novel full Galerkin
approach which employs rooftop functions defined on brick cells
inside the dielectrics. The input impedances of two microstrip
antennas have been computed with the new technique, showing
good agreement with respect measurements. Also the radiation
patterns of the antennas have been evaluated, showing again good
agreement with respect measurements. The practical value of the
approach is that microstrip circuits can ...
