BUILT-IN TYPE ANTENNA APPARATUS FOR MOBILE PHONE

摘要

A built-in type antenna apparatus for a mobile phone is provided to reduce an electromagnetic wave absorption rate by dispersing distribution of current concentrated on a feeding point in the mobile phone and securing a distance between a human body and an antenna, thereby improving a radiation performance of the antenna. A built-in type antenna apparatus(10) for a mobile phone includes a first planar antenna(20), a second planar antenna(30), and a ground stub(40). The first planar antenna has a first feeding point(21) and supplies a first radiation pattern. The second planar antenna has a second feeding point(31), is mounted on a position adjacent to the first planar antenna and supplies a second radiation pattern. The ground stub is arranged to be spaced apart from the first and second planar antennas at a predetermined distance, has a ground point(41), and supplies a ground pattern.
