A novel CPW-fed rectangle-trapezoid-rectangle shaped monopole antenna composed of a trapezoid and two rectangles is presented. In this context, the flat monopole structure improves the impedance bandwidth and reduces the size of the antenna dramatically. The ultra-wideband (UWB) antenna design plays a role as a filter. The coplanar waveguide...

In recent years, wireless communications have progressed very rapidly. Broadband antenna design has become very important for wireless applications. UWB is a high data-rate and short-range wireless technology, utilizing the unlicensed radio spectrum from 3.1 to 10.6 GHz. The UWB antenna is one of the major components of UWB...
