ABSTRACT
The wireless communication system very essential technology and have significant use after corona virus effect the world very badly. The Wi-Fi technology exhibits good wireless communication to provide internet facility but suffers with low antenna gain. This novel array proposed method with different dielectric material properties is used to enhancement the gain of the Wi-Fi antenna. The operating frequency of the proposed antenna is at 2. 5GHZ. This proposed method consist of Teflon dielectric material with dielectric constant of 2.02 has the gain of 8.4dbi, return loss of -30db and VSWR is 1.85, with loss tangent 0.0002. This proposed method compares with different dielectric material like kapton and fr-4 substrate but Teflon exhibit the good results. This proposed method work good for PCB antennas and flexible and wearable antennas with kapton substrate. © 2022 IEEE.
ABSTRACT
The COVID-19 pandemic is spreading throughout the world, infecting thousands of people every day. This public health emergency has got world and regional organisations, governments, and health care systems working tirelessly to try to control the spread of the virus and managing the already infected individuals adequately. These events have made everyone realise the policy of “Prevention is better than cure”, as the best way to fight this pandemic. There are many guidelines for common people, issued by many respected organisations, but most of them are focused on personal hygiene and prevention of the spread the virus. Only minimal focus has been given towards the role of immunity in this scenario and more importantly the role of nutrition in supporting immunity. In this article, it has been attempted to describe the term ‘Nutraceuticals’ and discuss in detail a few nutraceuticals which are well documented to support immune functions of the body. The article has tried to shed some light on the fact that these nutraceuticals deserve to be promoted amongst the masses, to support the immunity required against infectious diseases.
