A compact microstrip-fed ultrawideband (UWB) symmetrical inverted cone ring monopole antenna with dual band-notched characteristics for worldwide interoperability for microwave access (WiMAX) and wireless local area network (WLAN) is proposed. The proposed antenna which has the size of 23.6 × 40 mm2, is fabricated on a low-cost FR4 substrate that has the relative permittivity (εr) of 4.4 and substrate thickness of 1.6 mm to operate in the UWB band (3.1–10.6 GHz) released by Federal Communications Commission in 2002. A pair of L-shaped slots is etched symmetrically on the ground plane and L-shaped strip is added at the side of the microstrip feed line to reject 3.5-GHz WiMAX and 5.2/5.8-GHz WLAN band. The measured bandwidth of VSWR ≤ 2 is from 2.4 to 11 GHz with the band-notched of 3–4.2 GHz for WiMAX band and 4.9–6.1 GHz for WLAN band. Moreover, the proposed antenna exhibits omnidirectional radiation patterns with acceptable gain across the whole band. The prototype of the proposed antenna was fabricated and tested. The measured results agree well with the simulated ones.
