The present invention relates to a portable terminal, and more particularly, to mount a multi-band RFID antenna on the top or bottom of the terminal to perform the function of the RFID tag in multiple bands without unnecessarily increasing the size of the portable terminal. One relates to a portable terminal.

Recently, due to the rapid informatization, payment means for various goods and services have also gradually shifted from conventional cash or credit cards to electronic money using RFID systems. In particular, these days, most people have a personal portable terminal such as a mobile phone when they go out, and by carrying a non-contact electronic chip (RFID tag) that can be recharged in the personal portable terminal, the transportation fee is simply carried by the personal portable terminal. A large number of portable terminals capable of making payments and the like have been widely used.

In the case of such a personal mobile terminal, a loop type RFID antenna must be separately provided to form an induced electromotive force on the electronic chip. The position of the RFID antenna in the terminal is determined in consideration of its size and the shape of the personal portable terminal, and is generally looped along the outer circumferential surface of the battery pack 100 of the personal portable terminal as shown in FIG. 1. An antenna 102 is provided. However, when a loop antenna is configured in the battery pack, a separate material (flex flexor) for blocking radio waves and noise in the tens of MHz to several GHz bands must be added to the battery pack, thereby increasing the overall thickness of the battery pack. There was a problem. In addition, since the loop antenna operates only in one preset band, there is a problem that it cannot be used as a multi-band antenna.

The embodiments of the present invention mount a main antenna for wireless communication in a portable terminal on the top or bottom of the portable terminal, and simultaneously mount a multi-band antenna on the opposite side of the main antenna, that is, on the bottom or top of the portable terminal. Thus, it is intended to provide a means for using RFID tags in multiple bands without increasing the thickness of the portable terminal.

According to an aspect of the present invention, there is provided a portable terminal including an RFID tag, including: a main body on which a substrate including an electronic circuit for controlling a function of the portable terminal is mounted; A main antenna provided at one side of the substrate inside the main body and electrically connected to the electronic circuit; And an RFID tag including a multi-band RF ID antenna, the RFID tag being provided at the other side of the substrate in the main body and electrically connected to the electronic circuit.

In this case, the RFID tag may be a multi-band RFID tag used in two different frequency bands simultaneously or in two different frequency bands.

In addition, the RFID antenna may be configured in one or more of a dipole shape, a loop shape, or a coil shape.

The RF ID antenna of the dipole shape may further include a parasitic element.

Other aspects, features, and advantages other than those described above will become apparent from the following drawings, claims, and detailed description of the invention.

Embodiments of the present invention can embed the RFID tag in the portable terminal without unnecessarily increasing the thickness of the portable terminal. Also, by implementing the RFID tag in multiple bands, the portable terminal may function as an RFID tag in two or more frequency bands.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical spirit of the present invention is determined by the claims, and the following embodiments are merely means for efficiently explaining the technical spirit of the present invention to those skilled in the art.

2 is a block diagram of a portable terminal 200 including an RFID tag according to an embodiment of the present invention.

As shown, the portable terminal 200 including the RFID tag according to the embodiment of the present invention includes a main body 202, a substrate 204, a main antenna 206, and an RFID tag 208. .

The main body 202 is a portion in which the substrate 204 is mounted. In the case of a terminal having a keypad at the bottom and an LCD display at the top, such as a folding terminal, the lower part of the keypad is generally configured to the main body 202, and in the case of a bar type terminal, Since the terminal consists of one body, the terminal itself becomes the body 202 in the present invention. That is, the main body of the present invention is a part in which the substrate is mounted in the terminal, and may be a specific part of the terminal or the terminal itself according to the type of the terminal.

The substrate 204 is a part provided with an electronic circuit that controls the overall function of the portable terminal 200. As described above, the electronic circuit is a circuit for controlling the overall functions of the portable terminal 200 and includes a plurality of semiconductors for controlling the communication function, the input and output of signals, and other additional functions of the portable terminal 200. Can be. Details of the electronic circuit that controls the function of the portable terminal 200 are obvious to those skilled in the art, and thus detailed descriptions thereof will be omitted.

The main antenna 206 is provided at the bottom or top of the substrate 202 inside the main body 200 and is electrically connected to the electronic circuit. The main antenna 206 is an antenna used for signal transmission / reception with the base station of the portable terminal 200 and may be configured as a single band or a multi band antenna as necessary.

The RFID tag 208 includes a multi-band RFID antenna therein and is provided on the top or bottom of the substrate 204 inside the main body 202 and electrically connected to the electronic circuit. The mounting position in the main body 202 of the RFID tag 208 is determined according to the mounting position of the main antenna 206. That is, when the main antenna 206 is mounted at the bottom of the main body 202, the RFID tag 208 is mounted at the top of the main body 202, and the main antenna 206 is mounted at the top of the main body 202. In this case, the RFID tag 208 is mounted at the bottom of the main body 202. When the main antenna 206 is mounted on the bottom or top of the substrate 202 as described above, a free space is formed at the top or bottom of the main body 200 relatively. Therefore, when the RFID tag 208 is mounted in this space, the RFID tag 208 does not need to be attached to the battery cell, so that the portable terminal 200 does not increase the overall size of the portable terminal 200. Can function as

The RFID tag 208 may be configured as a multi-band RFID tag used in two different frequency bands simultaneously or in two different frequency bands. In general, the RFID tag uses NFC (13.56 MHz), UHF (900 MHz), or 2.45 GHz band, and the frequency band used varies according to the specific usage situation. Therefore, when the RFID tag 208 is configured in multiple bands, The use range of the RFID tag 208 can be extended.
