Abstract
The invention relates to a device comprising at least a first RFID module and a second RFID module, each comprising a chip coupled to a wire loop antenna. The first and second RFID modules operate at a first operating frequency into a first frequency band and at a second operating frequency into a second frequency band respectively, the second operating frequency being substantially equal to a multiple k of the first operating frequency, with k≥2. The device further comprises a resonant half-wave dipole having a length (L) that is substantially equal to λ/2 where λ is a wavelength associated to the first frequency band. The first module is present in the vicinity of the center of the half-wave dipole and the second module is present at a distance substantially equal to (2*n+1)λ/4*k from an end of the half-wave dipole, with n∈[0 . . . k−1].
