摘要：The invention concerns an RFID/NFC antenna circuit. An antenna (L) is formed byat least three turns (S), the antenna having a first end terminal (D) and a second endterminal (E), two access terminals () to connect a charge, a tuning capacitance (C, ZZ) fortuning at a prescribed tuning frequency, an intermediate tap (A) connected to the

antenna (L) and distinct from terminals (D, E), a first connector (CONA) connecting theintermediate tap (A) to terminal (), a second connector (CONE) connecting end terminal(E) to the capacitance terminal (CE). A third connector (CON, CON) connects the

capacitance terminal (CX) and the second access terminal () respectively to a first point (P)of the antenna (L) and to a second point (P) of the antenna (L) connected to the firstpoint of the antenna (L) at least one turn (S) of the antenna (L).
