Periodic structures and periodic antenna arrays have been widely studied and many techniques have been developed for their efficient analysis. Nevertheless, when it comes to aperiodic or non-uniform structures, most of these techniques can not be applied or they require longer computation times. In this work, the suitability of the Macro Basis Functions (MBFs) Technique for aperiodic arrays is shown and the performance of the different ways of determining these MBFs is studied. It is also shown how a baseline-based interpolation technique can be used in order to decrease the reduced impedance matrix filling time.
