The Design and Analysis of a High Bandwidth Patch Antenna Loaded with Double-L shaped Parasitic and Super-Strate Components

Abstract

A patch antenna having parasitic components in the shape of a double-L. It is shown how to make a directional slot antenna using a parasitic patch and a windowed superstrate. The recommended antenna may readily obtain high-gain properties due to its composition. The suggested antenna's impedance bandwidth has been measured. Internet of Things (IoT) apps to make their data more accessible, wireless communication technology integration is required. This work proposes a novel, the industrial 2.4 GHz portable and high gain L-shaped microstrip patch antenna, Scientific, and Medical (ISM) Internet of Things (IoT) applications.  The antenna is made of straightforward L-shaped strip lines, and it also includes a complete ground linked to the rear and a little rectangular slit constructed into it. Studies reveal that the created antenna outperforms conventional antennas in terms of efficiency and gain. Through a series of parametric simulations, the adaptability of the matching impedance and the efficacy of the antenna are examined. The findings show that the front L-shaped patch and the rectangular front gain may be modified. The operating frequency band, which spans the range of 11.81 GHz to 18.47 GHz, covers the whole Ku-band. The largest antenna size permitted is 30 mm x 30 mm. A patch measures 6.4 by 7.1 mm. An extremely superior gain and a very broad bandwidth of roughly 45% are provided by an efficient antenna. The antenna was constructed using HFSS 11.1.1. Ku band is largely used for fixed and broadcast satellite communications, as well as for specialist uses such relay satellites for communications between the space shuttle and space station.
