INTERNAL TYPE TERRESTRIAL DMB ANTENNA

摘要

An embedded terrestrial DMB(Digital Multimedia Broadcasting) antenna is provided to perform an impedance matching and an operational frequency tuning by forming a ring type line on an exterior of a carrier. An embedded terrestrial DMB antenna includes a carrier(100) which is formed on a ground portion. A radiating coil, a fixed metal member, and a feeder(400) are formed in the carrier. The radiating coil has a predetermined electrical resonance length. The fixed metal members are symmetrically formed at both ends of the radiating coil. The feeder is formed at one side of the metal material and feeds signals. A stub(500) is formed on an exterior of the carrier in a length direction of the exterior of the carrier. The stub is connected to the fixed metal material to face the feeder.
