Design and Analysis of Triple-Band Multi Slotted Microstrip Patch Antenna

Abstract

In this paper, a multi slotted microstrip patch antenna design has been proposed.The characteristics of the antenna are obtained in terms of return loss, gain and bandwidth.It is observed that the new proposed configuration can operate in three different frequency bands with a good amount of bandwidth i.e. bandwidth of 21.12% at 1.1GHz frequency band, bandwidth of 11.65% at 2.11 GHz and bandwidth of 13.05% at 2.76GHz frequency band .The resonating behavior in different frequency bands makes this antenna structure suitable for different types of applications with an antenna gain of 6.163dBi and antenna efficiency of 86.82%.The substrate material with relative permittivity of 4.2 and loss tangent of 0.0013 is used in this proposed antenna.The designing and simulation of the antenna structure is done over IE3D simulation software version 15.02.
