Integrated, lightweight, wideband antennas have received much attention following the development of wireless communications. The CPW-fed annular annular monopole antenna is a printed version of the Discone (also available in Antenna Magus) and achieves an ultra-wideband (UWB) impedance bandwidth of 8:1, while the radiation pattern transforms from omni-directional at the lower band to multipath at the upper band.
