Application Examples
Simulating a Beam Scanning Substrate Integrated Waveguide Leaky Wave Antenna in XFdtd
We simulate the performance of a leaky wave antenna implemented on a slotted substrate integrated waveguide. The antenna produces narrow beams that scan from near broadside to endfire as the frequency increases. The antenna has a wide impedance bandwidth and efficiency that improves with an increase in the operating frequency.

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.
