An anti-counterfeiting bottle includes a metal cap, a bottle body and a RFID (Radio-Frequency Identification) tag. The RFID tag includes a grounded surface, a monopole antenna and a RFID chip. The grounded surface is attached to the bottle body. The monopole antenna is attached to the bottle and is electrically connected to the grounded surface. The RFID chip is attached to the bottle and is electrically connected to the monopole antenna and the grounded surface respectively, wherein the RFID chip, the monopole antenna and the grounded surface form a loop structure. When the RFID tag is torn up, the loop structure is destroyed as well, such that the RFID tag cannot be read anymore, thus achieving the anti-counterfeiting function.

Anti-counterfeiting bottle

The present invention relates to an RFID tag having capacitive load, including: an antenna unit, a capacitive load and an RFID device. The antenna unit includes two metal sheets and a conductive substrate, and the metal sheets are disposed at a corresponding position above the conductive substrate and electrically connected to the conductive substrate. The capacitive load is electrically connected to the metal sheets. The RFID device feeds the antenna unit by electrically connecting to the metal sheets or coupling. This dramatically decreases the operating frequency, so the imaginary part of impedance is higher with the same size of the antenna unit, thereby reducing the size of the RFID tag. As a result, the weight is reduced, the manufacture process is simplified and the subsequent structure can be easily adjusted.

RFID tag having capacitive load

The present invention relates to an RFID tag holder, which comprises an RFID tag carrier used to carry an RFID tag, and a base having a circular surface, a holding portion and at least one magnetic component disposed therein. The shape of the circular surface matches that of the disposing hole, the magnetic component is used to make the disposing hole magnetically attachable to combine the base with the disposing hole, and two clip arms of a holding unit grip the holding portion and hold the RFID tag carrier after passing through two through holes of a metal substrate. The RFID tag holder has the following advantages: fast installation, low cost and reusability; is suitable for disposing holes with any depth and size; reduced interference and improved reading effect; no extra processing cost; dust-proof, water-proof and oil-resistant; and better composability, extensibility and flexibility.

A radio frequency identification tag device includes an antenna unit including a dielectric substrate that has two through holes extending from a first surface to a second surface opposite to the first surface, a first conductive layer disposed over the first surface of the dielectric substrate, a second conductive layer unit disposed over the second surface of the dielectric substrate and having opposite second conductive layers spaced apart from each other such that a spacer is formed between the second conductive layers, and two connecting conductors each disposed in a corresponding through hole in the dielectric substrate and interconnecting electrically a corresponding second conductive layer and the first conductive layer. A radio frequency identification module is disposed to span the spacer and is attached to the second conductive layer unit.

Radio frequency identification tag device for metallic products

A radio frequency identification (RFID) tag using a monopole antenna is provided, in which an antenna structure is disposed on a metal plate, two ends of an RFID chip are electrically connected to the antenna structure, and the antenna structure and the RFID chip form a loop structure. The RFID tag can be disposed on a surface of an object to be measured, or disposed in an inner accommodation space of the object to be measured, so it is widely used in various applications. Additionally, the RFID tag is easily manufactured, so the production cost can be reduced. Furthermore, the RFID tag has a larger readable distance, and an electromagnetic wave emitting direction of the RFID tag is adjustable according to different included angles between the metal plate and the antenna structure, thereby causing signals to be read easily and identification ability to improve, two desirable effects.
