Rfid tag having capacitive load

Номер: US20130228627A1
Автор: Sung-Lin Chen, Yi-An Wu
Принадлежит: China Steel Corp

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.

A method of forming an electrically-conductive pattern includes selectively electroplating the top portions of a substrate that corresponds to the pattern, and separating the conductive pattern from the substrate. The electroplating may also include electrically connecting the conductive pattern to an electrical component. Conductive ink, such as ink including carbon particles, may be selectively placed on the conductive substrate to facilitate plating of the desired pattern and/or to facilitate separation of the pattern from the substrate. An example of a conductive pattern is an antenna for a radio-frequency identification (RFID) device such as a label or a tag. One example of an electrical component that may be electrically connected to the antenna, is an RFID strap or chip.
