By virtue of an antenna system which is installed within a same of the antenna and ensures the transmission at high flow of the radio signals - electrical

摘要

To date, we may note that the systems of amplification and matching impedances intelligent are offered. do not make it possible to transmit the signals at the top flow rate of the technical problems that this results, particularly in terms of electromagnetic compatibility (or "cem ") and the costs of production. In this new antenna system we show the system of modulation / demodulation (11), just after the "amplification - impedance matching ", and this set of" adjustment " modulation / demodulation - amplification is installed within the antenna which is itself fixed on a metal structure. The invention described above makes it possible to reduce the costs for the manufacturers, while introducing new services.
