Microstrip reflectarrays: Full-wave analysis and design scheme

摘要: An analytical approach and a design scheme based on highly efficient full-wave analysis technique CG-FFT (conjugate-gradient fast Fourier transform), are presented for accurately analyzing large microstrip reflectarrays in very detailed manner throughout the whole procedure. A trial reflectarray has been designed using proposed approach. It was then constructed tested. The experimental results compared with simulated results. is considered that, to get an accurate focus point of reflectarray, it crucial know precise phase shift reradiated field each single patch array caused by connected short transmission lines. >
