MIMO ANTENNA USING MOBILE PHONE GROUND

摘要

The present invention relates to a MIMO antenna using a ground of a mobile communication terminal, which includes a planar inverted F antenna (PIFA) surrounded by the ground and an inverted F antenna (IFA) not surrounded by the ground. According to the MIMO antenna, a main antenna hybriding the IFA to the PIFA which is fed with electricity through coupling feeding is faced. According to the present invention, the MIMO antenna can obtain good efficiency and gain by surface emission of a PIFA structure, even though a rear surface of a substrate where the PIFA is formed is the ground. And the MIMO antenna can satisfy a low frequency band by adding an IFA structure fed from the PIFA through coupling feeding, and can secure wider bandwidth by being able to obtain double or more multiple resonance.
