MULTI BAND INTERNAL ANTENNA FOR MOBILE HANDSET

摘要

A multi band antenna for a mobile communication terminal receives a multi band signal by using one miniaturized built-in antenna. A ground conductor(300) has a ground potential. One side of a feeding point(110) is connected to the ground conductor. One side of an input element(100) is connected to the feeding point and the input element is composed of a feeding line having a predetermined line. A parasitic radiation element(200) is physically separated from the input element at a predetermined interval. The parasitic radiation element includes at least one conductive line contributing to resonant frequencies of the multi band.
