Waveguide Ports in XFdtd

Application Examples

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.

Application Examples

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.

Application Examples

A band-pass filter is simulated showing the use of substrate integrated waveguides in XF.
