Abstract

En terminal designet for kommunikasjon med kontaktløs type databærere med to forskjellige bærefrekvenser har to resonnanskretser (1,11) for den ene og den andre bærefrekvensen. Begge resonnanskretsene (1,11) bruker en og samme antenne (A) og en kondensator (Cl, C3) i hvert tilfelle. I resonnanskretsen (II) for lav bærefrekvens er det anordnet en koplingsinduktansspole (L) mellom kondensatoren (C3) og antennen (A).
