STACKED MULTI-BAND ANTENNA EMBEDDED IN A MOBILE COMMUNICATION TERMINAL AND A PIFA ANTENNA USING A DIELECTRIC AND FERRITE CAPABLE OF IMPROVING RADIATION EFFICIENCY

摘要

PURPOSE: A stacked multi-band antenna embedded in a mobile communication terminal and a PIFA antenna using a dielectric and ferrite are provided to suppress the reduction of efficiency of an antenna by using ferrite as a part of an antenna board.;CONSTITUTION: A feeding point(103) transmits and receives an RF signal. A first feeding line(105) is connected to the feeding point. A first feeding port(106) is connected to an RF transceiver of a mobile communication terminal. Ferrite(201) supports a fourth generation mobile communication LTE frequency band. A second feeding port(205) transmits and receives moving pictures, voices, and packet data and is connected to a second feeding line(204).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Antenna1(laminate multiband antenna); (BB) Ground(GND); (CC) Antenna2(antenna using ferrite and FR3 dielectric); (DD) Overall structure of suggested multiband antenna
