Paper Abstract

Based on electromagnetic wave radiation theory, the important parameters of the receiver antenna is analyzed, we analyze the relationship between the receiving antenna array characteristics and the method of improve antenna array gain. The receive performance is compared between a single receiver antenna and the antenna array. Based on the refractive index fluctuation of atmosphere follow the Kolmogorov power spectrum, the relationship between the receiving antenna array and improve coupling efficiency are analyzed in free-space optical communication systems through atmospheric turbulence. The simulations show that the receiving performance of antenna array is better than a single large aperture antenna. The optimum number of the sub-antennas and aperture diameter differ according to the area of the antenna array. In different atmospheric turbulent, the effect of improve coupling efficiency are analyzed between a single receiver antenna and the receiving antenna array. In the aspect of improve the coupling efficiency, the antenna array is better than optical antenna in medium, strong atmospheric turbulent.
