Signals and Telecommunication Journal Abdulaleem A. Rasheed, Manaf E. Al-sabbagh, Saad W. Osman 1 2 2012 http://www.dline.info/stj/fulltext/v1n2/4.pdf The expanding use of wireless devices has prompted the need of larger bandwidths by these devices. This need is a result of larger bit-rates or the use of different standards using different frequency bands. In this work, Ultra Wide Band (UWB) 2-14GHz with its matching circuit is presented. The antenna responses, input impedance radiation pattern, currant distribution and VSWR at various frequencies are studied and compared to that of a commercial antennas . The viability of this antenna is tested using the simulator of CST-2010 tool.
