Device for emission of data and/or control signals for transponder system, has synchronizing circuit adapting resonance frequency of antenna arrangement in inductive or capacitive manner in transition phase in stable modulation condition

摘要

The device (1) has a signal generator (3) that is connected to an antenna arrangement (6). Another signal generator (4) is connected to another antenna arrangement (7). An oscillator provides oscillating signals to control signal generators. A synchronizing circuit (2) receives a signal of modulation of data and/or of control, and adapts resonance frequency of the former antenna arrangement in an inductive or capacitive manner during a transition phase with regard to resonance frequency determined for carrier frequency of antenna arrangements in a stable modulation condition. An independent claim is also included for a method for setting data and/or control signals emission device in motion.
