A Compact CPW-fed Rectangle-trapezoid-rectangle Shaped Monopole Antenna for Ultra-wideband Systems

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...
