Abstract
A transponder, a method for powering the transponder, and a system relating to the method. The transponder includes at least two electrical coils, a dipole antenna, and a chip electrically connected to the dipole antenna and the electrical coils, wherein the electrical coils surround the dipole antenna and the chip. The transponder is surrounded with a wiring loop. An alternating current is generated in the wiring loop. The alternating current generates a magnetic field at the electrical coils. The electrical coils receive energy from the magnetic field and transfer the received energy to the chip for powering the transponder. The dipole antenna is configured to transmit an output signal to a reader and to receive an input signal from the reader.
