MIMO/DIVERSITY ANTENNA IMPROVING ISOLATION FOR THE SPECIFIC FREQUENCY BAND

摘要

PURPOSE: An MIMO/diversity antenna improving the isolation of a specific frequency band is provided to minimize a current component distribution by forming a connection pattern with a meander line shaped strip line. CONSTITUTION: A ground surface(1) is formed on a printed circuit board. A planar inverted-F antenna(100,200) includes an antenna pattern. The antenna pattern includes a radiation unit, a feeding unit, and a ground unit. A feeding pad(410) and a ground pad(420) are formed on a printed circuit board without a ground surface. A connection pattern(500) connects the ground surface to the ground pad.
