摘要
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.
