- Wireless IC devices and composite parts for wireless IC devices are provided.
- the present invention relates to a wireless IC device, in particular, a wireless IC device used for an RFID (Radio Frequency Identification) system, and a composite part for a wireless IC device used for the wireless IC device.
- a wireless IC device used for an RFID (Radio Frequency Identification) system
- RFID Radio Frequency Identification
- Patent Document 1 U.S. Pat.No. 6,406,990
- Patent Document 2 U.S. Pat.No. 6,664,645
- the wireless IC chip 301 is directly connected to the antenna pattern 304 via the Au bump 302, and the wireless IC chip 301 is attached to the support film 305 having a very large area. Need to be positioned above. However, it is extremely difficult to mount a small wireless IC chip 301 on a large support film 305 with high accuracy. If a position shift occurs at that time, or if the size of Au bumps varies, There is a problem that the resonant frequency characteristic of the antenna changes. In addition, since the frequency characteristics of this wireless IC device are substantially determined by the shape and size of the antenna pattern 304, the antenna pattern 304 may be rounded or sandwiched between dielectrics. For example, the characteristic is easily changed by being sandwiched in a book).
- the resonance frequency of the transmission / reception signal in this wireless IC device is basically determined by the electrical length of the antenna pattern. For example, when a transmission / reception signal of 13.5 MHz band is handled with an air core type antenna pattern, an inductance value of approximately 4.5 H is required, and the antenna pattern becomes large.
- the present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a small wireless IC device having a stable frequency characteristic and a composite component for the wireless IC device. .
- a wireless IC device includes a wireless IC chip, a power supply circuit board including the wireless IC chip and having a power supply circuit including an inductance element, and the inductance element of the power supply circuit.
- a wireless IC device including a radiation plate that is coupled by electromagnetic field, wherein a high permeability magnetic body portion made of a high permeability magnetic material is formed on at least a part of the feeder circuit board. And at least one part of the said inductance element is provided in the said high-permeability magnetic body part, It is characterized by the above-mentioned.
- the wireless IC chip since the wireless IC chip is mounted on the power supply circuit board, the wireless chip can be mounted on the board with high accuracy, and the power supply circuit board has a radiation plate and an electromagnetic field. Since they are connected by coupling, they can be easily attached by arranging the composite parts such as the wireless IC chip and the power supply circuit board directly or close to the radiation plate.
- the frequency of the transmission signal and the reception signal is substantially determined by the power supply circuit provided on the power supply circuit board, for example, even if the radiation plate is rounded or sandwiched between dielectrics, the frequency A stable frequency characteristic without substantially changing the characteristic can be obtained.
- the inductance element that constitutes the power feeding circuit is formed in the high magnetic permeability magnetic part. Therefore, the Q value of the inductance element can be improved, and even if the size of the inductance element is reduced, stable frequency characteristics can be obtained, and the feeder circuit board and thus the wireless IC device can be reduced in size. be able to.
