A CPW Fed Octagonal Patched Antenna for UWB Applications

In this paper, we present a CPW fed octagonal patch antenna with hexagonal slot for ultra wideband (UWB) application. The proposed antenna is designed on FR4 substrate with dielectric constant 4.4 has dimension 29 X 31 mm2 and it covers a frequency range of 3.1 - 10.6 GHz for (VSWR?2). The fundamental parameters of the antenna such as return loss, VSWR, 2D radiation patterns, gain and bandwidth are obtained and all meets of the acceptable antenna standards. The simulation results of this antenna are analyzed by using Zealand IE3D version 15.10 which is based on Method of moments.
