Pyramidal Horn

Description - A pyramidal horn designed to operate at 10 GHz. The feed is an x-band waveguide.This project uses PMLs for its radiation boundary.

Model - The horn has 0.02" wall thickness and is defined as PEC. The port is internal to the solution region and is capped by a PEC object (cap). PMLs are included in the model and are defined on the faces of air_box. Their visibility, by default, has been turned off.

Setup - Adapt at 10 GHz.

Pyramidal Horn Post Processing

After solving, you can view solution data by right-clicking on Setup1 and selecting Profile to display the Solution dialog. You also view the Solution tabs for Convergence, Matrix Data, and Mesh Statistics.

To view 3D plot of the antenna gain, look in the Project Tree under Results and double click on 3D Polar Plot 1. To overlay the 3D plot on the model, click HFSS>Fields>Plot Fields>Radiation Field to display the Overlay radiation field dialog. Check Visible for 3D Polar Plot 1, and set the transparency and scale as desired.

To view a 2D plot of the dB gain total, look in the Project Tree under Results, and double click on Radiation Pattern 1

A shade plot showing the fields on the Y-Z plane has also been created and can be viewed by right-clicking on E Field under Field Overlays and selecting Update.
