RADIO IC DEVICE AND RADIO IC DEVICE PART |
摘要 |
It is possible to provide a radio IC device and a radio IC device part having stable frequency characteristic. The radio IC device includes: a radio IC chip (5); a feed circuit substrate (10) having the radio IC chip (5) mounted thereon and a feed circuit (16) containing a resonance circuit having a predetermined resonance frequency; and an emission plate (20) bonded to the lower surface of the feed circuit substrate (10) for emitting the transmission signal supplied from the feed circuit (16) and supplying the reception signal to the feed circuit (16). The resonance circuit is formed by an LC resonance circuit having an inductance element (L) and capacitance elements (C1, C2). The feed circuit substrate (10) is a multi-layer or single-layer rigid substrate and connected to the radio IC chip (5) and the emission plate (20) by DC coupling, magnetic coupling, or capacity coupling. |
