TRANSMITTER, FIELD COMMUNICATION TRANSCEIVER, AND FIELD COMMUNICATION SYSTEM

Title:

TRANSMITTER, FIELD COMMUNICATION TRANSCEIVER, AND FIELD COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2006/059684

Kind Code:

A1

Abstract:

A transmitter comprises transmission means (3) for transmitting a modulating signal having information modulated, a transmission electrode (8) for inducing an electric field based on the modulating signal, in a field transmission medium (20), a stray capacity to be established between the ground (6) of the transmission means (3) and the earth ground (14), a stray capacity to be established between the field transmission medium (20) and the ground (6) of the transmission means (3), a stray capacity to be established between the field transmission medium (20) and the earth ground (14), first reactance means (2) interposed for resonance between the output of the transmission means (3) and the transmission electrode (8), and second reactance means (1) interposed for resonance with the individual stray capacities between the output of the transmission means (3) and the ground (6) of the transmission means (3) or between the transmission electrode (8) and the ground (6) of the transmission means (3).
