Patent ID: 7760147

Claim:
A mobile terminal, comprising: a case configured to include a circuit board; and an antenna disposed inside the case, the antenna comprising: an antenna pattern formed on a substrate; a feed unit having a first end connected to the antenna pattern and a second end connected to the circuit board, and configured to supply an electrical signal to the antenna pattern; and an Electromagnetic Interference (EMI) attenuation unit disposed in a location corresponding to the feed unit and configured to attenuate EMI generated by the feed unit, wherein the EMI attenuation unit comprises a material having a dielectric constant that is variable and comprising at least two layers having different dielectric constants, wherein the feed unit further comprises a metal contact formed on one side of the substrate and a feed point connected to the metal contact, wherein the EMI attenuation unit is formed on the metal contact, and wherein the metal contact, the EMI attenuation unit, and the substrate are laminated such that a surface of a first side of the metal contact is in contact with a surface of the one side of the substrate, and a surface of a second side of the metal contact is in contact with a surface of one side of the EMI attenuation unit, the second side of the metal contact being an opposite side of the first side.
