A novel and compact triband planar antenna geometry suitable for DCS/WLAN/WiMAX services is reported. The multiple metal strip geometry in dual F shape is printed on a substrate of dielectric permittivity 4.4 and thickness 1.6 mm. A truncated and asymmetrically placed ground structure is used for improved impedance matching. Feed position is also optimized for good antenna radiation performance. The geometry is simulated using High Frequency Structure Simulator. All the radiation characteristics of the antenna are validated experimentally and found in good agreement with simulation results. Performance of the proposed antenna is compared with other triband antennas reported in the literature. Measured radiation patterns and gain are also presented in this paper. The radiation patterns are validated by EMSCAN Corporation's RFxpertTM application tool also.
