The paper proposes to use meandered grounded stubs to design single or dual band-notched planar-monopole antennas for ultrawide band (UWB) applications. The center-notch frequencies and notch bandwidths of the UWB antennas can be adjusted by using the dimensions of the meandered grounded stubs. Two prototype antennas are designed, fabricated and studied. One has a single band notch in the wireless area network (WLAN) band from 5.15 GHz to 5.825 GHz and the other one has two sets of dual-band notches at the lower WLAN band (5.15-5.35 GHz) and higher WLAN band (5.725-5.825 GHz). The band-notched characteristics, radiation patterns and peak gains of the antennas are studied using computer simulation and measurements.
