Abstract
Wireless technology is one of the main areas of research in the world of communication systems today and a study of communication systems is incomplete without an understanding of the operation and fabrication of antennas. This was the main reason for our selecting a project focusing on this field. In this project a simple structure of Ultra Wideband (UWB) antenna is proposed. The antenna offers excellent performance for UWB system, ranging from 3 GHz to 10 GHz. The antenna exhibits a 10 dB return loss bandwidth over the entire frequency band. The antenna is designed on FR4 substrate and fed with 50 ohms micro-strip line. This antenna is composed of a modified shaped patch with a partial slot ground plane and a height of 1.6 mm that shields the low-cost substrate material FR-4 with a relative permittivity of 4.4 and loss tangent of 0.002 that makes it suitable for UWB operations. 50Ω micro-strip transmission line used as feed current and observe the simulated results in HFSS software. With a decent impedance match and constant radiation pattern the presented antenna has comprehensive bandwidth of 14 GHz (0.96 GHz to 15 GHz) which makes the antenna appropriate for various ultra-wideband applications. It is found that the frequency band depends on the width of the partial ground width, the width of the feed line and position of the feed line.
