Card-type information recording medium having embedded antenna for near field communication and manufacturing method thereof

摘要

A card-type information recording medium having an embedded antenna for NFC communication is provided. The card-type information recording medium includes: a PCB that has a loop antenna pattern and a routing pattern formed on the top surface and the bottom surface thereof through the use of an etching process; an NFC communication unit and a USIM card unit that are horizontally mounted on the top of the PCB; and a molding material that is formed on the top of the PCB to cover the NFC communication unit and the USIM card unit. Accordingly, it is possible to perform functions of NFC and RFID read/tag by only mounting a USIM device thereon without adding any module or any constituent having an antenna function to a mobile terminal.
