Abstract:
|
The numerical analysis of highly iterated Sierpinski
microstrip patch antennas by method of moments (MoM) involves
many tiny subdomain basis functions, resulting in a very large
number of unknowns. The Sierpinski pre-fractal can be defined
by an iterated function system (IFS). As a consequence, the
geometry has a multilevel structure with many equal subdomains.
This property, together with a multilevel matrix decomposition
algorithm (MLMDA) implementation in which the MLMDA
blocks are equal to the IFS generating shape, is used to reduce the
computational cost of the frequency analysis of a Sierpinski based
structure. |
