Based on designed hyperbolic metamaterial (HMTM) substrate, we report enhancement of radiation directivity of the metallic optical nano-antenna in the visible spectrum. Placing monolayer and sub-layers as substrate for the optical nanoantenna results in radiation directivity changing. The far-field radiation patterns of the designed structures have been calculated using FEM (finite element method). The COMSOL package has been used for obtaining the directivity characteristics. It has been shown that a HMTM substrate enhances the radiation field amplitude from 82 to 94 V/m. It is established that by novel arraying of nano-particles and tailoring their metamaterial substrates, one can successfully engineer the radiation patterns and beam angles.
