摘要：

Radiation pattern direction control is one of the most important capabilities of nanoantennas required in optical wireless nano-link for emitting into or detecting from the desired direction. In this work, a novel triangle nanoantenna operating in the near-infrared region is proposed in which the angle of maximum power emission is tuned via rotating one of the triangles and fixing the remaining ones. The advantage of this theme is the result of using piezoelectricity to tune the gap between nano-particles in a nano-antenna and also the possibility of tuning the angle of the pattern up to 25 degrees. By adding a nano-particle to the structure and varying its location, the radiation pattern can be rotated in the desired angle.
