A triple band antenna of a mobile communication terminal is provided to increase a bandwidth and a gain of the triple band antenna by adding a coupled line to respective loop antennas. A triple band antenna for a mobile communication terminal includes a first loop antenna(10) and a second loop antenna(20). The first loop antenna includes a feed terminal, a ground terminal, and a first coupled line(13). The second loop antenna is coupled with the first loop antenna via a through-hole and includes a second coupled line(21). The second loop antenna is laminated on the first loop antenna. The first and second loop antennas have rectangular shapes. The loop lines of the loop antennas have convexo-concave portions. The first and second coupled lines are formed at opposite loop lines.
