Efficient approach for the analysis of large antennas by using windowed macro-basis functions

The approach presented here deals with large structures that cannot be handled by conventional rigorous methods. The methodology entails the use of two different partitioning levels: windows and blocks. A full coupling analysis is performed within each window, while we donpsilat consider any coupling between adjacent windows. The results have been validated for smooth geometries and comparisons with rigorous methods. The authors are currently working on an improvement of the technique which also includes interactions between windows.
