Rayleigh distance
WebHowever unlike the far field region, the shape of the radiation pattern varies significantly with distance. Far Field. When talking about antennas the far field is the region that is at a large distance from the antenna. In the far … WebMerci pour votre réponse, mais je pense que ma question n'a toujours pas vraiment de réponse. Permettez-moi de reformuler la question : Comment pouvons-nous passer de la formulation du critère de Rayleigh que j'utilisais (θmin=1.22*λ/D) à celui que vous utilisiez (d=1.22*λ/NA), sans utiliser le petit approximation angulaire.
