ANTENNA DEVICE FOR PORTABLE TERMINAL

摘要

An antenna device for a portable terminal is provided to realize impedance matching without an extra inductance element and capacitance element by installing an inductance part and a capacitance part on a third radiator. An antenna device for a portable terminal includes a first radiation part(211), a second radiation part(212), and a third radiation part(213). The first radiator is connected to one of RF(Radio Frequency) terminals of the portable terminal through a feeding terminal. The second radiator is connected to the first radiator. The third radiator is elongated from the first radiator and is connected to THE other RF terminal of the portable terminal through the feeding terminal. The third radiator includes an inductance part and a capacitance part. The inductance part is linearly elongated from the first radiator. The capacitance part is elongated from the inductance part and is formed as a 'U' type by being folded.
