Analysis and Design of the Dielectric Yagi-Uda Nanoantenna with a Double Driven Element
The Yagi-Uda silicon nanoantenna with the double driven element and 4 directors is proposed here.The simulation of single Si nanoparticles with a diameter between 40 and 53 nm shows an increasing of the directivities for all emitter locations.The trend of the directivity appears to be random as the nanoparticle dimension and emitter distance increase.For the double driven element,the directivity profiles as a function of the radius appears to be wavelike forms.The directivity is clearly determined by two competing factors that are particle coupling and dimension.The directivity of the Yagi-Uda Si nanoantenna can be improved with more number of directors.The maximum directivity of the proposed structure with optimized geometric parameters is 11.42.The preliminary numerical model for predicting the directivity of this antenna is determined.The directivity can be further improved to 12.52 by reducing the gap between the double driven element and the first director.
