Patent ID: 8860616

Claim:
RFID antenna system comprising: at least a first RFID antenna device comprising a magnetic antenna and a second RFID antenna device comprising at least one plane antenna, the plane antenna generates radiation in a first frequency range (f 1 ), the magnetic antenna generates radiation in a second frequency range (f 2 ) lower than the first frequency range (f 1 ), and the second RFID antenna device comprising the at least one plane antenna arranged inside or in front of the frame-shaped or loop-shaped magnetic antenna, in such a way that the vertical projection of the metal, earth and/or reflector plane of the at least one plane antenna is inside the frame-shaped or loop-shaped magnetic antenna, the second RFID antenna device comprises one of the plane antennae or an array antenna comprising at least two plane antennae, and the plane antennae comprises for this purpose either a) a metal plane as a radiator device, which is divided into metal plane portions by slots, interruptions and/or recesses, the metal plane portions being galvanically isolated from or connected to one another, or b) an earth or reflector plane which acts as a balancing antenna or reflector and is provided in addition to the radiator device, projects laterally past the radiator device, and is divided into earth or reflector plane portions by slots, interruptions and/or recesses, the earth or reflector plane portions being galvanically isolated from or galvanically connected to one another, further including at least one and preferably a plurality of connecting bridges interconnecting two adjacent metal, earth or reflector plane portions, via concentrated components, wherein the connecting bridge(s) consist of individual or a plurality of concentrated active and/or concentrated passive components.
