This paper describes radiation characteristics of the printed circular twin half-loop antenna on truncated ground plane. The FDTD (Finite-Difference Time-Domain) method has been applied in the analysis of this antenna. The measured maximum VSWR of the antenna is less than 1.5:1 over the 8.1-to 9.4-GHz band. Radiation patterns measured at 9 GHz are approximately equal to the monopole antenna on truncated ground plane. A VSWR<2:1 may be achieved over wide bandwidths.
