MULTI-BAND ANTENNA CAPABLE OF IMPROVING FREQUENCY TRANSMISSION/RECEPTION PROPERTY IN A MULTI-BAND AND A MOBILE TERMINAL THEREOF

摘要

PURPOSE: A multi-band antenna and a mobile terminal thereof are provided to improve the transmission/reception property of a multi-band antenna by forming a modifying part in a carrier.;CONSTITUTION: A carrier(210) is made of dielectric materials. A radiator(220) is installed on the surface of the carrier. The radiator includes a first and a second branch(213,214). The first and the second branch form different routes each other. The modifying part(230) is formed in a part of the carrier corresponding to adjacent region of the first and the second branch. The modifying part changes the dielectric constant of the carrier when the electromagnetic wave is transmitted/received through the radiator. The modifying part is formed by cutting out a part of the carrier.;COPYRIGHT KIPO 2010
