A multiband monopole antenna covering DTV and several popular wireless communications was presented. The antenna fed by a microstrip line comprises a ladder‐shaped patch and a notched ground plane. By precisely choosing the dimensions of both the patch and the ground, dual wide continuous impedance bandwidths of 880 MHz (0.51–1.39 GHz) and 1.66 GHz (2.11–3.77 GHz) applicable for multiband wireless operation can be easily achieved. Also, the monopole‐like type of radiation patterns and the average gains of about 0.1 and 4.5 dBi, respectively, over the lower and upper operating bands have been obtained. © 2009 Wiley Periodicals, Inc.
