Abstract :
The biconjugate gradient-fast Fourier transform (BCG-FFT) method is a very efficient and useful technique to analyze microstrip antennas and arrays. In order to increase the efficiency of the BCG-FFT method by reducing the number of iterations, a multilevel BCG-FFT method is constructed using the idea of multi-grid methods. The analysis of microstrip antennas and arrays shows that the multilevel BCG-FFT method has good accuracy and is faster than the BCG-FFT method
