Abstract :
Matching networks with Non-Foster elements seem to be useful for the matching of small antennas. This paper presents the advantages and disadvantages of such a non-Foster matching network with active elements. Therefore a comparison with a conventional matching network regarding signal performance only and in addition regarding signal-to noise (SNR) performance for automotive application in the FM frequency range is made. In contrast to other publications a severe SNR disadvantage of the non-Foster network results.
