Abstract
In this paper a novel doubly resonant threedimensional 3D nanodisk Yagi–Uda antenna conceived for realizing wireless optical links within electronic circuits is proposed The prominent emitting properties of this nanoantenna have been deeply investigated both in the near and far field through a useful comparison with a more traditional 3D nanorod Yagi–Uda antenna The behavior of the nanodisk antenna both configured as a single nanoantenna and arranged in planar arrays have been illustrated emphasizing its improved performances with relation to crucial aspects as directional features wavelength bands of operation frequency tuning and polarization influence on radiation In particular the single nanodisk antenna has been accurately designed to enhance the transmission feature in the near field at the wavelengths λ = 13 and λ = 155 μm Also the emission pattern of the array of nanodisk antennas has been properly tailored to ensure high peaks of directivity and narrow beam width in those ranges Hence efficient unidirectional angle patterns have been shaped for any operation wavelength and dimensions of the array reaching extremely effective outcomes for a 3 × 3 array which exhibits a maximum of directivity of 19 and 176 and −3 dB points at 18° and 21° for λ = 13 and λ = 155 μm respectivelyThe authors acknowledge COST Action MP0805 on Novel Gain Materials and Devices Based on IIIVN Compounds and also the CINECA Award for the proposed project SPMAPS Surface Plasmon Management in Active and Passive Systems 2011 and for the availability of high performance computing resources and support TD thanks the Consorzio Nazionale Interuniversitario per le Telecomunicazioni CNIT aid grant for newly graduates MG thanks partial financial support from the Army Research Office W911NF1110284 1490AM01
