“…The novel coronavirus pandemic has an impact on our growth and better lives. Contact between humans has been limited to maintaining a social distance, but communication between gadgets and tools remains linked (Atzori et al 2010 ; Nasajpour et al 2020 ; Velliyangiri et al 2022 ). IoT systems are used in various applications, including the industrial environment, the medical field, and public transportation (Sauter & Lobashov 2011 ; YIN et al 2016 ).…”

An artificial magnetic conductor (AMC)-based patch antenna with a low profile is developed for wireless devices in IoT-based healthcare systems. The proposed antenna comprises two pairs of circular-shaped patches with circular-shaped slots and a dual-band 4 × 4 array of AMC reflectors with two zero-degree reflection responses to enhance the antenna's radiation performance. For the 2.45 GHz ISM and 5.4 GHz WLAN bands, the patch antenna has dimensions of 0.44 λ 0 × 0.52 λ 0 × 0.013 λ 0 , with partial ground structures to improve radiation characteristics. Following that, a unique dual-band symmetrical AMC unit cell with dimensions of 22 × 22 × 1.6 mm 3 is developed. There is a gap of 15 mm between the antenna and the AMC surface. The antenna is supported by a 4 × 4 AMC array that has a total dimension of 0.72 λ 0 × 0.72 λ 0 × 0.15 λ 0 . The reflection coefficient values of less than − 10 dB in the 1.7–2.5 and 5.1–5.6 GHz bands, with a bandwidth percentage of 38 and 9.3%, respectively. The antenna's gains were 7.2 and 4 dBi inside the bands. Furthermore, the Specific Absorption Rate (SAR) value did not match the WHO's safety and health guidelines. The issue was solved by including an AMC surface in the proposed antenna. At 2.45 and 5.4 GHz, SAR values of 0.58 and 1.04 W/Kg were measured. Vector network analyser and anechoic chamber were used to test the performance of antenna and AMC surface prototypes. There is a substantial agreement among measured and simulated parameters of an antenna. Consequently, the developed antenna combination with the AMC structure is suited for wireless devices in ISM and WLAN bands, often used in IoT-based healthcare systems.

War, pollution, and a plethora of other threats are prevailing in the world on a daily basis. The globe, which has a population of more than 7.3 billion, is constantly harmed by human activity. Climate change is one of the world's most lethal problems because of these severe deformations. UN reported that 10000 people have died in extreme weather events like fire and floods in the past two years. Globally, $280 billion is lost to climate catastrophes from 2021 to 2022. While a single action won't be able to stop or slow down climate change, many tiny contributions from several professions will help it have an emotional effect. Scientists from all over the world are looking for ways to manage the transformation of the landscape in order to anticipate the dangers of climate change and, if possible, to reduce their effects on the future of the earth. Particularly with the Internet of Things (IoT), it is possible to slow the increase in global temperatures and cut back on hothouse emigration. The Internet of Things (IoT) encompasses more than just cutting-edge gadgets and intelligent machinery since it affects the state of the planet, from its climate to its financial resources. If we use technology effectively, it may be the instrument that saves the world. Since it involves everything from monitoring ozone levels in a meat packing facility to keeping an eye on public trees for banks, environmental monitoring is a broad activity for the Internet of Things (IoT). These findings mark the beginning of the process of developing several interconnected architectures that will support cutting-edge services and have greater effectiveness and flexibility.
