Beschreibung
Zusammenfassung:	An active antenna using a dielectric resonator is provided to be miniaturized in a comparatively low frequency band and contribute to miniaturize various RF terminals and apparatuses in addition to terrestrial DMB(Digital Multimedia Broadcasting). An active antenna using a dielectric resonator(110) includes the dielectric resonator and a resonance circuit. The dielectric resonator resonates at a predetermined frequency band. The resonance circuit is coupled to the dielectric resonator and shifts a resonance frequency band of the dielectric resonator. The resonance circuit is composed of a core coil(120). A variation range of the resonance frequency band is determined according to user operation. The dielectric resonator and the resonance circuit are formed on a PCB(Printed Circuit Board).
