- Abstract
- The Contour-FFT is a recent method based on the Method of Moments which is intended to analyse very large irregular antenna arrays printed on layered substrates. This method relies on some parameters that can be hard to adjust for certain cases: typically thin or high-permittivity substrates. In this work we propose a simple hybrid spectral/spatial domain approach to overcome this problem, and we show that it very efficiently improves the accuracy without altering the attractive time complexity of the Contour-FFT. We also propose to apply the Contour-FFT only to the portion of the spectral domain that contains the contour, leading to important time saving factors.
