A Tri-forked Antenna for UWB applications

Communication over short distances with high speed is now possible due to ultra wideband (UWB) technology. Planar small printed antennas have shown to be unmatched in terms of performance and simplicity of integration in portable devices, a lot of effort and research has gone into the design of UWB antennas for a variety of applications, including scans, position, and radar systems, as well as wireless connectivity. To encompass the ultra - wide operational bandwidth of the UWB applications, a variety of Ultra - wideband have been designed. The potential uses of Wireless communication technology have been currently becoming more and more obvious. In this paper, a 30mmx30mm x 1.6mm FR-4 substrate-based UWB antenna is presented with truncated ground and tri-forked shaped in the patch. The substrate thickness is 1.6 mm, the dielectric constant is $\varepsilon$r=4.4 and the loss tangent is tan$\delta$=0.02, which achieved bandwidth of 6. 8GHz and having Omni-directional radiation characteristics.
