LOOP ANTENNA FOR CELLULAR PHONE

摘要

PURPOSE: A loop antenna for cellular phone is provided to improve the communication between the loop antenna and a card reader by inserting a ferrite sheet between a battery and the loop antenna. CONSTITUTION: A loop antenna(111) is installed at a battery. A top plate part and a bottom plate part are combined each other by using a hinge. The top plate part and the bottom plate part are operated by a battery(105). The battery(105) is adhered on the top plate part or the bottom plate part. A magnetic layer(33) is inserted between the loop antenna(111) and the battery(105). The magnetic layer(33) is formed with a ferrite sheet. A plurality of PCBs are installed on the top plate part and the bottom plate part.
