Broad dualband fork-shaped CPW-fed monopole antenna

A printed wideband monopole antenna is proposed for dualband wireless communication. The antenna is a notched patch fed by a coplanar waveguide (CPW) and resembled in a fork shape. The effect of embedded notch on the impedance matching condition has been examined. The proposed antenna has been constructed and experimentally studied. The antenna explores good radiation characteristics including two available bands with 10 dB return loss bandwidths of about 490 MHz centred at 2.13 GHz band and of about 99.2 % ranging from 3.32 to 6.9 GHz, a stable radiation pattern, and average gains of greater than 2.6 and 4.8 dBi, respectively, over the two operating bands.
