Document Type and Number:
WIPO Patent Application WO/2024/034877
Kind Code:
A1
Abstract:
The present invention relates to a card ring. The card ring comprises: an integrated circuit element (IC chip) for control and a booster circuit module; a loop antenna; and a body portion having a ring shape and on which the integrated circuit element for control and the loop antenna are mounted. The body portion includes a slit formed by completely cutting a region of the body portion, an antenna groove, and an integrated circuit element groove, wherein the loop antenna is mounted in a state of being wound several times along the antenna groove, the integrated circuit element for control is mounted in the integrated circuit element groove, and the exposed slit, the antenna groove, and the integrated circuit element groove of the body portion are filled with curable epoxy. The booster circuit module includes a circuit having a certain capacitance, wherein, as the capacitance is determined according to a shape and size of the body portion of the card ring, operating frequency of the integrated circuit element is adjusted.
