BUILT-IN ANTENNA HAVING A SMALL RADIATOR PREVENTING PERFORMANCE DEGRADATION CAUSED BY HAND EFFECTS AND HEAD EFFECTS

摘要

PURPOSE: A built-in antenna having a small radiator is provided to reduce an entire antenna size by performing an operation in a lower frequency band in comparison with a length by changing a shape of the radiator.;CONSTITUTION: At least one radiators(306,308) are disposed as being spaced from a substrate(300) as much as a predetermined distance. A feeding unit(302) feeds an RF(Radio Frequency) signal to the radiator. At least one of the least one radiators includes a high capacitive structure element of a plate form and a high inductive structure element of a thin line from. The high capacitive structure element has a width bigger than a feeding line of the feeding unit. The ground unit(304) provides ground voltage and is electrically connected to the radiator. The high inductive structure element and the high capacitive structure element are periodically repeated.;COPYRIGHT KIPO 2010
