摘要

PURPOSE: An antenna device of a portable terminal is provided to secure radiation performance by grounding one side of an antenna with a battery cover of a metallic material.;CONSTITUTION: A radiation part(10) transmits and receives electric waves. A feeding part(20) is formed in one end of the radiation part. The feeding part connects electrically the radiation part with a printed circuit board. A ground part(30) is formed in one side of the radiation part in order to maintain a constant distance from the feeding part. The ground part comes in contact with one side of the battery cover in a coupling state of the battery cover. An antenna device is loaded into a carrier.;COPYRIGHT KIPO 2010
