Such a micro SD card 10 has a standard size of 11 mm x 15 mm. Therefore, the GHz band has a short frequency wavelength so that the antenna can be built without changing the size of the micro SD card, but antennas of the HF (13.56 MHz) and UHF (800 MHz to 900 MHz) bands cannot be embedded.

For the same reason as above, conventionally requires a dedicated terminal equipped with a separate antenna 20 in the battery or the rear cover of the mobile phone, when the micro SD card to the mobile phone antenna connection pad 15 and the antenna of the micro SD card 20 is used to connect and enable RFID wireless recognition.

As described above, in order to apply RFID technology to a mobile phone, a dedicated terminal equipped with an antenna 20 on a battery or a rear cover must be required. In addition, there is another method of embedding both the RFID reader IC and the antenna in the USIM, but in this case, the compatibility problem is caused by using the current value (maximum 30mA is the maximum) that can be generally used in the USIM. Occurs, and cannot guarantee the correct action or intended action.

The present invention has been made in view of the above, by incorporating an antenna of 13.56MHz HF band and 800 ~ 900MHz UHF band in the micro SD card, even existing mobile phone users to install only the micro SD card RFID card or reader function Its purpose is to provide a micro SD device with a built-in antenna for use.

Micro SD device with an antenna according to the present invention for achieving the above object, the body portion is inserted into the micro SD card mounting portion of the mobile phone; And an SD interface partitioned into a gripping portion for inserting a micro SD card into the mounting portion and electrically connected to the terminal. At least one NAND memory module; An SD controller connected to the SD interface to connect communication between a terminal and the NAND memory module; At least one smart card IC capable of data communication with the SD controller; An RFID reader capable of data communication with the SD controller or the smart card IC; And an antenna connected to the RFID reader, wherein the gripping portion is expanded to a size two times larger than a standard standard, and the antenna is embedded in the extended gripping portion.

According to a preferred embodiment of the present invention, the gripping portion may extend in the height direction or the longitudinal direction. When the gripping portion extends in the height direction, the height thereof is preferably 2.3 to 2.5 mm, and when the gripping portion extends in the longitudinal direction, the length thereof is preferably 4.5 to 5.5 mm. More preferably the height is 2.4mm, the length may be 5.0mm.

In addition, the antenna may be an antenna of the HF (13.56MHz) band or an antenna of the UHF (800 ~ 900MHz) band.

In the micro SD device having the antenna according to the present invention, since the antennas of the HF and UHF bands are embedded in the micro SD card, even if the terminal is not a dedicated terminal for RFID wireless recognition, only the micro SD device is installed in the existing terminal. The reader function can be used, thus eliminating the compatibility problem caused by using the existing dedicated terminal.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For reference, in describing the embodiments of the present invention, if it is determined that detailed descriptions of related well-known functions and configurations may unnecessarily obscure the subject matter of the present invention, detailed descriptions thereof will be omitted.

2A and 2B are various embodiments showing the external structure of a micro SD device with an antenna according to the present invention. As shown in FIG. 2A and FIG. 2B, the micro SD device incorporating an antenna according to the present invention is divided into a body portion 100 and a grip portion 200. As shown in FIG.

The body portion 100 is formed of a micro SD card standard size for insertion into a terminal, for example, a micro SD card mounting portion 510 of the mobile phone 500 as shown in FIG. 4, and at one end thereof is electrically connected to the terminal. There is an SD interface 110 having a plurality of pads (eight or more compatible with the micro SD standard) to be connected.

3A and 3B, at least one NAND memory module 120 and the SD interface 110 are connected to the body 100 to communicate with the terminal and the NAND memory module 120.
