“…Recently, various nano‐antennas with different geometries such as bowtie, spiral, dipole, and Vivaldi have been investigated for solar energy harvesting. We begin with the nano‐dipole antenna that consists of two metallic rods and is easy to realize and to optimize, with a simple nano‐circuit that can be optimized to increase the sensitivity of the nano‐antenna.…”

Three efficient infrared-printed dipole nano-antennas are designed on a dielectric substrate for infrared energy harvesting. The three printed dipoles have different shapes, namely, rectangular, curved bowtie, and elliptical. These antennas are designed in to collect maximum electric field in the gap between the two poles in the frequency band of 28to 29THz, which is chosen because the received infrared power is maximum at 28.3 THz. A parametric study of the three proposed dipole shapes is performed to increase the localized electric field as well as modify to achieve resonance frequency at 28.3 THz. A parametric study is carried out to determine the dipole length, width, gap size, substrate thickness, and ground plane thickness. Next, the three dipoles are exposed to different polarizations incident plane waves in order to study the effect of the polarization of the incident wave on the electric field induced in the gap and to compare the performances of the three designs. The comparison study shows that at 28.3 THz, the curved bowtie dipole shape collects a larger electric field than the rectangular and elliptical shapesdo.
