MULTIBAND INTERNAL ANTENNA USING LOOP STRUCTURE

摘要

PURPOSE: A multiband internal antenna using a loop structure is provided to secure a multiband characteristic by applying a capacitive element and a loop structure. CONSTITUTION: A feeder radiation element(100) is electro-magnetically combined with a feeder point. One end of an earth connection element(102) is combined with an earth part(106). A main radiation element(104) is extended while maintaining an electromagnetic coupling with the feeder radiation element. A capacitive element(200) is serially combined with the feeder radiation element. The feeder radiation element, the earth connection element, and the earth part form a loop(150).
