| 摘要 |
The invention relates to an RFID/NFC antenna circuit, comprising an antenna (L) made of at least three turns (S) on a substrate, the antenna having a first end terminal (D) and a second end terminal (E), two access terminals (1, 2) for connecting a charge, a tuning capacitor (C1) at a predetermined tuning frequency, an intermediate connector (A) connected to the antenna (L) and separate from the terminals (D, E), a means (CON1A) for connecting the intermediate connector (A) to the terminal (1), and a means (CON2E) for connecting the end terminal (E) to the capacitor terminal (C1E). According to the invention, third means (CON31, CON32) are provided for connecting the capacitor terminal (C1X) and the second access terminal (2) to a first point (P1) of the antenna (L) and to a second point (P2) of the antenna (L) connected to the first point of the antenna (L) via at least one turn (S) of the antenna (L), respectively. |
