Design Analysis Fabrication And Investigationof Flexible Softwear Microstrip Antenna For Bio Medical Application

Abstract

Microstrip antenna is an integral part of the most modern newlineequipment with a low profile, low cost antenna for many wireless newlineapplications, especially in bio medical applications. Three main newlinecategories of flexible antennae are namely wearable antenna, textile newlineantenna and softwear antenna. Softwear microstrip antenna plays a newlinemajor role in biomedical applications, since it is a flexible, a noninvasive, newlinesafe, relatively painless, sensing human body parameter, newlineantenna with less radiation, which is suitable for wireless body area newlinenetwork. In this research work different structures of softwear microstrip newlineantenna with textile substrates were designed, simulated and analyzed newlinefor various parametric performances. Various experiments were newlineperformed to prove that all softwear antennae are flexible and sensing newlinevarious off body and on body parameters. newlineThis thesis presents the design, simulation and investigation of newlinevarious structures of softwear microstrip antenna which is suitable for newlinebio applications. Various softwear antennae are designed, simulated, newlinefabricated and investigated with different parameters by using Network newlineanalyzer. Research work started with a design of a flexible softwear newlinecotton textile antenna with dielectric constant and#8455;r = 1.6 and it was newlineworking in ISM band. The parameters were measured and the antenna newlinewas tested in various bending conditions. When the antenna was newlineinstalled and in corporate as a part of the clothing, different parts of the newlinehuman body like elbow, wrist and other parts of the body.Wherever newlinehuman body movement is possible, bending action takes place, newlineaccordingly frequency shift was observed in bending movements. Hence newlineviii newlinethe softwear antennae flexibility and its bending ability for any bending newlineenvironment were established. Human body is made up of water, newlinedissolved organic molecules, insoluble matter and ions. All these newlinecomponents are composed of electrical permittivity and conductivity. newlineThe biological human body property is interrelated with electromagnetic newlinefield parameters such as intensity of
