ABSTRACT:
A monopole antenna is disclosed. The monopole antenna comprises a base board, a first substantially L-shaped conductor, a first ground plane, a second substantially L-shaped conductor, a second ground plane and a feeding strip, and the monopole antenna further has a plurality of evenly-distributed through holes penetrating the base board from the first substantially L-shaped conductor to the second substantially L-shaped conductor. When the monopole antenna is operated at about 2.4–2.5 GHz, good radiation patterns and antenna gain are obtained for being applicable to IEEE802.11b/g specifications.
