PLANAR INVERTED-F ANTENNA USING MULTIPLE COUPLIG FEEDING

摘要

An inverted-F antenna using multiple coupling feeding is provided to maintain a stable characteristic regardless of external interference by feeding each conductive pattern independently through the multiple electromagnetic coupling. A dielectric block(100) has a polyhedral shape. A feeding pad(200) is formed in a lower part and one side of a dielectric block. A first conductive pattern(220) is fed by the current inputted to the feeding pad. A second conductive pattern(230) is fed by the current inputted to the first conductive pattern. A third conductive pattern(240) is fed by the current inputted to the second conductive pattern. The first to third conductive patterns are fed by the electromagnetic coupling method. A ground pad is formed in the lower part of the dielectric block. The ground pad is connected to one end of the first conductive pattern and the third conductive pattern.
