A marker for locating and identify assets which includes an ultra-high frequency (UHF) radio frequency identification (RFID) tag optimized for use below ground and able to more effectively communicate with a RFID reader through a lossy medium such as soil and air. The markers include a reflector which is sized relatively larger than the tag to help focus the forward pattern of the tag more tightly in a forward direction normal to the spiral surface. In addition, the tag includes a chip configured for the soil in which it is to be buried, and an antenna polarized to match the polarization of an RFID reader antenna that is part of a system that includes the marker and reader.

An insert for a chip card includes a body provided with a cavity in which is inserted an electronic module provided with a microelectronic chip connected to an inductive or capacitive coupling. The body has a stack of layers at least a first layer of which comprises a first booster antenna and a second layer of which comprises a second booster antenna, the various booster antennas being coupled together inductively and/or capacitively, and at least one of the booster antennas being coupled inductively and/or capacitively with the coupling of the module. The body furthermore comprises at least one metal plate disposed between two layers of ferrite, the first and second booster antennae and the metallic plate being arranged in such a way that at least one of the two booster antennas and the electronic module remain coupled together inductively and/or capacitively, despite the presence of the metal plate.

An antenna device includes a power feed coil to be connected to a RFIC and a coil antenna that couples with the power feed coil.
