The current study proposes a hybrid plasmonic horn-like nanoantenna with a silicon-on-insulator (SOI) configuration. This nanoantenna can be utilized for broadband nanophotonic applications and can operate in a wide optical frequency range of 160–400 THz. It includes optical communication wavelengths of 850, 1310 and 1550 nm. This nanoantenna can directionally radiate and receive signals with about 74% bandwidth within the operational wavelength spectrum. The proposed nanoantenna is simulated using the finite element method and produced nanoantenna gains of 4.7, 7.3 and 4.8 dB and a reflection coefficient ( S 11 ) of −15.7, −12.8 and −15.6 dB at optical wavelengths of 1550, 1310 and 850 nm, respectively.
