An irregular polygon slotted rectangular microstrip antenna for WI-MAX and WLAN application

Abstract

In this paper, we discussed about irregular polygon rectangular microstrip antennas for WI-MAX and WLAN applications. The antenna designing on 2.5GHz frequency, and analyzed the antenna using IE3D simulation software. Here we uses the glass epoxy dielectric substrate, the dielectric constant of material is 4.4, loss tangent is 0.0012 and having the 1.6mm substrate height. The bandwidth of antenna is 39.3%, the efficiency of antenna is 90% and radiation efficiency is 100% and the antenna achieve return loss is -16.1db.The resonant frequency of antenna is 2.5 GHz.
