Abstract
In this paper, a pentagon shaped ultra-wideband (UWB) antenna is proposed and developed for wireless communication systems. This antenna has low profile, light weight and has successfully demonstrated multiband and broadband characteristics. The simulated results show that proposed antenna has very good performance in impedance bandwidth and radiation pattern. A better impedance bandwidth is obtained from 3.1 GHz to 13.48 GHz that constitutes a fractional bandwidth of 125 % with return loss less than or equal to -10 dB (VSWR < 2). The comparative results reveal that the proposed antenna possesses wider bandwidth than the earlier published structure. This designed antenna can be used for any wireless UWB device for high data rate applications.
