Abstract

This paper presents the analysis of simple, compact, CPW- fed flower shaped monopole aperture antenna with 10dB return loss (VSWR<;;2) band from 3.365 GHz to 10.235GHz except the band 4.775-5.825GHz(5GHz WLAN) for UWB applications. The antenna consists of ground plane, rectangular slot and a flower - shaped exciting stub. The flower - shaped stub is simple and has less parameter, which are convenient to optimize. The proposed antenna is designed on an inexpensive FR4-epoxy substrate with dielectric constant ϵ_r =4.4 and with a size 30mm×25mm×1.5mm. The fundamental parameters of the antenna such as bandwidth, return loss, gain, radiation pattern and polarization are obtained. All meets the acceptable antenna standards. Simulation tool, based on the method of moments (ZELAND IE3D version 12.0) has been used to analyze and optimize the proposed antenna.
