A comparative performance analysis of inverted F antenna using different substrates

This paper presents a comparative performance analysis of Inverted F antenna using various substrates. Natural cork, Plastic and Wood plastic are used as its substrate and the results are compared with the results of using FR4 substrate. This antenna is simulated using Ansoft's HFSS software. The antenna performances are also analyzed using different widths of its radiating surface. It is designed with capacitive element so that the phase variation be minimum in current flow and enhances the radiation efficiency. The designed antenna covers the ISM band, WLAN (2.4-2.484 GHz), LTE2300, LTE2500 applications and also 6.96-7.20 GHz for private use.
