A monopole antenna ( 10 ) includes a feed wire ( 14 ), a radiation part ( 18 ), and a matching part ( 16 ). The feed wire is formed on a clear portion of a substrate for feeding electromagnetic signals. The radiation part is connected to the feed wire for radiating and receiving electromagnetic signals, and includes a first radiation part ( 180 ) and a second radiation part ( 182 ). The second radiation part is connected to the first radiation part, the first radiation part is formed on a first plane, and the second radiation part is formed on a second plane intersecting the first plane. The matching part is connected to the radiation part for impedance matching.
