摘要：
We report on a comprehensive investigation of radiation characteristics of THz emitters using structures based on the Sierpinski fractal. Self-similarity present in the geometrical properties of these antennas improves the coupling of emitted radiation to free space. Using THz-TDS it is shown that these novel antennas produce higher radiation power when compared to the bow-tie antenna. To the best of our knowledge this is the first time that Sierpinski fractal antennas have been used as emitters for generating THz radiation.
