Microwave Device Simulation Software & Components

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.

Videos

In this video, a Remcom engineer walks through the steps to set up and tune a Ku Band microstrip lens in Rotman Lens Designer (RLD). Included is a discussion of the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script to automatically set up the ports and include the material properties.

Videos

This video is a tutorial that shows a rectangular waveguide being built using XF’s modeling techniques. You will learn how to use XF’s built-in materials library, create the waveguide interface, solve for and display lowest-order TE modes, and display the field results.
