RETRACTED ARTICLE: Internet of Thing based Koch Fractal Curve Fractal Antennas for Wireless Applications

Abstract

The demand for Internet of Things (IoT)-based broadband antennas is growing in tandem with the development in high-bandwidth applications in wireless communication. An ultra-wideband (UGB) antenna design idea based on a novel and compact fractal antenna design concept is offered in this research. With high data rates (480Mb/s) and strong signal splitter characteristics with a wide bandwidth (0.528–7.5 GHz), UGB technology was created for wireless personal area networks (WPANs) with a high bandwidth (0.528–7.5 GHz). Simulated signal levels of −41.3 dBm/MHz were reported in the first band group of the UGB band (BG:1, 3.1–4.752 GHz) for the first band group of the UGB band. Auto identical and comparable radiation pattern features are shown by the fractal antenna architecture across a wide range of wavelengths. As a result, they would be highly suited for use in multi-band orthogonal frequency division multiplexing (MB-OFDM)-based universal gateway systems. The suggested fractal antenna design was tested and shown to have return loss (11 S) values less than -20 dB for the whole UGB frequency range (3.1 – 10.6 GHz). Furthermore, it has been shown that BG:1 has radiation pattern features that are unidirectional.
