Abstract
in this paper, design and performance analysis of Co-Planar Wave-guide (CPW) feed ultra-wide band (UWB; 3.1 ~ 10.6 GHz) for next generation wireless communication devices has been investigated. The proposed antenna is fabricated on a FR-4 substrate of thickness h = 1.6mm having loss tangent of 0.02 and dielectric constant of ξr = 4.4 and has been analyzed using HSFF simulation software. The proposed antenna provides a simulated VSWR ≤ 2 bandwidth of 2.35 – 10.78 GHz. The proposed antenna exhibits good electrical characteristics in both time and frequency domain, stable gain over the UWB range and almost omnidirectional radiation patterns making the antenna suitable for wireless applications.
