An RF tag that includes an inlay (made of an IC chip and an antenna); an auxiliary antenna laminated on the inlay in an insulated state; and a housing that houses the inlay having the auxiliary antenna laminated thereon. Furthermore, the antenna of the inlay forms a loop circuit adjacent to the IC chip, and the auxiliary antenna overlaps part of the loop circuit and is arranged along a longitudinal direction of the inlay such that at least a part of the antenna of the inlay is exposed.

RF tag

An RF tag that includes an inlay (made of an IC chip and an antenna) and a housing that houses the inlay therein. Furthermore, the housing comprises a top cover that covers at least an upper surface side of the inlay, the top cover is made of a predetermined metal material, the top cover includes a cutaway that opens in the upper surface side of the inlay, and the top cover is electrically connected to the inlay to function as an auxiliary antenna of the inlay.

Provided is a bag making apparatus with a simple configuration that: prevents fluctuations in tension, slippage of seal positions, and meandering or skewing of a web of film; allows the setting of precise initial conditions; reduces or makes unnecessary monitoring, and time and structures for adjustment; allows increased feed rate; and improves production efficiency. The bag making apparatus for packaging containers comprises: a tension control unit for controlling the continuous feed rate according to the values detected by a tension sensor of a tension detection roll; an optical detection unit for simultaneously recognizing multiple marks provided on the surface of the web of film at the respective positions thereof; a skewing correction unit; and a seal position correction unit for adjusting the positions of multiple sealing units in the feed direction.

Bag making apparatus

An RF tag includes an inlay comprising an IC chip and an antenna, a planar auxiliary antenna laminated on the inlay in an insulating state to the inlay, and a substrate on which the inlay and the auxiliary antenna are laminated. The auxiliary antenna is formed into a rectangular planar shape including long sides each having a length of substantially &#xbc; of a wavelength of a radio wave frequency of the inlay, and has a cutout part which divides one of the long sides into two parts each having a length of substantially &#x215b; of the wavelength of the radio wave frequency of the inlay. The cutout part is formed into a concave shape which is opened in an edge portion of the one of the long sides and has a predetermined width and depth to allow the IC chip of the inlay to be disposed therein.

An RF tag has an inlay with an IC chip and an antenna, a planar auxiliary antenna laminated on the inlay in an insulating state, a dielectric constant regulation plate which becomes a base on which the inlay including the auxiliary antenna laminated thereon is mounted, and functions as a dielectric constant regulation layer for the mounted inlay, and a case which receives the dielectric constant regulation plate in a state where the inlay including the auxiliary antenna laminated thereon is mounted. The dielectric constant regulation plate is formed into a shape which allows the dielectric constant regulation plate to be attachably/detachably and non-movably engaged in the case and which allows the dielectric constant regulation plate to have a predetermined dielectric constant which regulates communication characteristics of the inlay including the auxiliary antenna laminated thereon.
