MOBILE-TELEPHONE BUILT-IN ANTENNA USING ANTENNA PATTERN FORMED ON SUBSTRATES HAVING DIFFERENT PERMITTIVITY, AND MOBILE TELEPHONE USING THE SAME

摘要

PURPOSE: An antenna built in a mobile communication terminal using an antenna pattern part formed in a substrate having different dielectric constant, and the mobile communication terminal using the same are provided to support various supplementary services only with the built-in antenna, thereby increasing the degree of freedom of mobile communication terminal design. CONSTITUTION: One or more first substrates(110) have first dielectric constant. A second substrate(120) has second dielectric constant. An antenna pattern part(130) is formed through the first substrate and the second substrate. The antenna pattern part has a feeding terminal(131). The feeding terminal receives electricity from the main board of a mobile communication terminal. An antenna pattern is formed by connecting lines formed in the front and rear sides of a PCB(Printed Circuit Board) to a thru via(140).
