Design and fabrication of a microstrip printed T monopole antenna for ISM application

Abstract

A T-shaped Printed monopole antenna with low profile and fed by 50Q inset feed techniques on FR4 substrate is proposed which finds application in Wireless Local Area Network (WLAN). This project work aims in designing a compact uni-planar Antenna with high gain for Wireless applications using inset feed technique. This frequency 2.4GHz (2.256-2.687 GHz) shows that antenna is suitable for WLAN application. This simulation results obtained are acceptable for ISM (Industrial, Scientific, Medical radio) band applications and it finds immediate application for studsat (student satellite). The results are obtained by simulating the antenna structure using simulation tool Ansoft HFSSTM and measurements were carried out using Vector Network Analyzer. The results show that there is a 0.2 GHz shift in the measured resonant frequency with considerable improvement in the Gain and vswr.
