The performance of a visible optical communication system is limited by the effect of severe light power attenuation in application scenes of non-line-of-sight (NLOS) propagation such as shadow occlusion, etc. Thus, we propose a kind of optical receiving antenna coupled with spherical bionic compound eye micro-lens group and a compound parabolic concentrator. By using TracePro to analyze the non-imaging characteristics of bionic compound eye of spherical surface, we find that the ratio of energy collection increases with the decrease of angle of the neighbor's eye axis when the area of detection surface is certain. When the included angle between adjacent optical axes is less than local optimal value, the energy collection rate is more than 90%, which is close to the optimum. There is a positive correlation between the local optimal value of the angle of the optical axis and the area of the detector. With the increase of angle of the neighbor's eye axis, the character of large field of vision (FOV) of bionic compound eye is gone. For the application of NLOS link of indoor visible light communication, the antenna gain can reach 56.45 and the angle of FOV is larger than 90°. Compared with the ordinary single-lens antenna, it is clear that the bionic compound eye multilevel coupling optical antenna can maintain a high light feeding power in the case of severe shading, and the average power is increased by 20 dBm. It also shows that the design of the optical antenna with large FOV and high gain characteristics can effectively improve the anti-shadowing performance of indoor visible light communication system.
