Abstract

The present invention discloses a device for data or energy transmission. Device according to The present invention presents an oscillating circuit (3, 4), which is excited by an excitation magnitude for oscillation. Oscillation is transmitted in a transforming way to a transposer oscillating circuit (5, 6). In order for data or energy transmission to be as effective as possible, current or tension is measured in antennae oscillating circuit (3, 4) and it is compared to a theoretical magnitude. In the event of a deviation a correction value is generated, through which excitation current is increased or fR resonance frequency is leveled to fE excitation frequency due to an impedance (C, L) additional connection to antennae oscillating circuit (3, 4).
