Remcom's XFdtd software is well-suited for any microwave device design or analysis task. Our Waveguide Examples booklet showcases a collection of five different waveguide applications with downloadable project files.
Examples include:
• Microstrip Gap Waveguide on Electronic Band Gap Substrate
• Rectangular Waveguide Mode Converters
• Waveguide Cross-Coupled Filter Simulation
• Slotted Waveguide Antenna
• Wideband Pseudo-Elliptic Waveguide Filter
Application Examples
A dual-band, dielectric-loaded horn antenna is analyzed with XFdtd to demonstrate performance at 94 and 340 GHz. The antenna consists of a dual port rectangular waveguide section at the feed end that transitions to a circular waveguide and then a conical horn at the output side. The horn structure radiates the 94 GHz signal while a tapered dielectric block in the center of the structure guides the 340 GHz fields. The antenna has a strong single beam with a peak gain around 18 dBi that is symmetrical in the E and H planes.

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.
