Abstract
We realize a new design of tapered Yagi-Uda nanoantennas and experimentally study their far-field light scattering. We show that in comparison with untapered structures the tapered nanoantennas exhibit broadband resonances featuring a distinct line shape. Our observations are supported by numerical calculations, which further reveal the tapered nanoantenna's wavelength-dependent optical near-field confinement.
