Abstract
An antenna to be used with transponder type devices. The antenna includes an inductance and a capacitor forming a resonant circuit. To avoid any heating and to have a sufficiently broad passband or operating range, there is in parallel with the inductance, a branch comprising two Zener diodes connected in opposite directions. Any nonlinear damping arrangement having an equivalent effect may be used in the branch.
