ANTENNA STRUCTURE FOR FREQUENCY-RECONFIGURABLE OPERATIONS

摘要

PURPOSE: An antenna structure for a frequency reconstruction operation is provided to improve a broadband characteristic by improving an input impedance matching characteristic. CONSTITUTION: A first radiator(130) is formed on a ground plate. The first radiator transmits and receives a signal of a first frequency band(B1). A second radiator(140) is formed on the first radiator. The second radiator transmits and receives the signal of a second frequency band(B2) higher than the first frequency band. A battery feed unit(110) is formed on the upper side or lower side of the ground plate. The battery feed unit receives the signal through the radiator corresponding to a receiving frequency.
