Abstract
A terminal for contactless communication with portable objects comprises a wave pickup device responsive to the magnetic component of an electromagnetic field, and a receiver which cooperates with the wave pickup device to receive and amplify signals picked up thereby. The wave pickup device comprises at least two distinct and adjacently disposed wave pickup elements spaced apart by a predetermined gap, and a discriminator for deriving a discrimination signal from the signals picked up by each of the wave pickup elements during a given period. The discrimination signal indicates which one of the wave pickup elements has received a signal of greater amplitude.
Claims4
A terminal for contactless communication with portable objects, said terminal comprising:
- a wave pickup device responsive to a magnetic component of an electromagnetic field;
- and
- a receiver co-operating with said wave pickup device to receive and amplify signals picked up thereby;
- wherein said wave pickup device further comprises:
- at least two distinct wave pickup elements of substantially similar dimensions which are plane and disposed adjacent to each other and which are separated from each other by a predetermined gap, said wave pickup elements being substantially vertical and defining two passages on either side of a midplane;
- and
- a discriminator for discriminating the side of a midplane on which a signal-emitting portable object is situated, said discriminator deriving a discrimination signal from signals picked up by each of said wave pickup elements during a given period, wherein the discrimination signal indicates which one of said wave pickup elements has received the signal of greater amplitude.
