Simulating Performance of a Low Cost, Chipless RFID System in XFdtd

This example uses XFdtd to simulate the performance of a low cost, chipless RFID system. The RFID tag is comprised of two ultrawide band monopole disk antennas mounted in a cross-polarized configuration combined with a microstrip line adjacent to six varying size spiral resonators which each represent a single bit in the RFID tag code. The system is validated using two cross-polarized log periodic dipole arrays as the send and receive devices.
