A planar monopole antenna is provided. The planar monopole antenna comprises a ground plate, a radiating metal plate, and a multi-branch feeding metal plate. The multi-branch feeding metal plate is formed between the ground plate and the radiating metal plate, and has a single feeding point thereon. The radiating metal plate and the multi-branch feeding metal plate together can also be fabricated from a single metal plate by using a line-cutting or stamping technique, or formed on a same dielectric substrate by using a printing or etching technique. Thus, the planar monopole antenna is easy to construct at a low cost.
