Abstract
A folded dipole loop antenna has a matching circuit integrally formed therein. The antenna includes a radiating unit formed in the shape of a loop, and the matching circuit has an extended part projected and extended toward a central area of the radiating unit from an inner side surface of the radiating unit, thereby eliminating the need for a separate space for the matching circuit. The antenna can change a resonant frequency thereof by adjusting input reactance through the matching circuit.
