Abstract

The proposed antenna system integrates advanced materials electromagnetic properties tuning to allow real-time steering to the antenna main beam direction. We explore a tuning mechanism based on changing the chemical potential differences (μc), through including a chiral single wall carbon nanotube (SWCNT) structure with a plasmonic resonance effect at the optical regime. Such change in the value of μc realizes a manipulation in the angular emission pattern change to enhance the beamforming capabilities to the desired requirements. This steerability provides substantial benefits for applications such as optical communication systems. The obtained results validate that the proposed nano-dipole antenna shows significant improvements over other traditional antennas in terms of size reduction with acceptable radiation efficiency, directivity, and tunability. The integration of the proposed design within next optoelectronic generations can floor the way to the compact, high-performance systems with enhanced capabilities for optical communication systems and photonic circuitry. This study presents a steerable plasmonic nano-dipole antenna with dynamic electromagnetic radiation control, designed for modern communication. The antenna operates across a wide frequency range, with a primary focus on the visible spectra 300 THz to 700 THz. By utilizing resonant plasmonic effects, the antenna achieves a radiation efficiency of 57% and a directivity of 4.5 dBi. We introduce a beam-steering mechanism that enables angular radiation steering up to ±25° from the central axis. Control mechanisms include electrical tuning via applied μc voltage from 0 V up to 1 V and optical tuning using laser excitation around 600 THz. Simulations confirm that beamwidth narrows from 30° to 10° at resonance, enhancing spatial precision. The validated results show a tunability of 200 THz in the operational wavelength, with a response S11 below -10 dB. These features demonstrate that the antenna operation has a potential for integration into next-generation optoelectronic devices, offering compact and efficient solutions for wireless communication, remote sensing, and optical imaging systems. This is achieved by leveraging the resonant interaction between surface plasmon polaritons and nano-dipole geometry, and we demonstrate the ability to achieve highly directional and tunable radiation across a wide range of frequencies, including visible and near-infrared spectra.
