A miniature coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna is presented. This antenna consists of a modified half annular ring radiator and the notched CPW ground plane which are used to extend the bandwidth and reduce the overall size of this antenna. Measured results show that this antenna operates from 3.4 to 10.6GHz for voltage standing wave ration (VSWR) less then 2 and has relatively stable radiation patterns over its whole operation band. This antenna also has a very compact size, only 0.22 × 0.28λ2at 3.4GHz.
