MULTIPLE BAND ANTENNA

摘要

A multi-band antenna is provided to facilitate application to different portable terminals by including a plurality of tuning units, thereby extending an application range thereof. A multi-band antenna includes a first radiator(100), a second radiator(200), and a feeder(400). The first radiator has a first resonance length(L1) to generate resonance corresponding to a first resonance frequency through a coupling effect with the adjacent radiator. The second radiator faces the first radiator and has a second resonance length(L2) to generate resonance corresponding to a second resonance frequency through a coupling effect with the first radiator. The second radiator has a slit, and one end thereof is connected to a ground(300). The feeder feeds power to the first and second radiators.
