An antenna structure based on the geometry of the bent folded monopole is described in this letter. This novel tapered bent folded monopole is designed to cover popular frequency spectrum of the 2.4 and the 5 GHz wireless local area network (WLAN) bands. The proposed antenna capable of dual-frequency operation is fed by the coplanar waveguide (CPW) and fabricated on the RO4003 substrate. Obtained numerical results are in good agreement with the experimental data. It has been validated that the configuration can meet the demands for the WLAN systems and effectively enhance the impedance bandwidth to 12.5% for the lower band and 32.4% for the upper band for VSWR < 2 : 1.
