ANTENNA FDTD STUDIO · APPLICATION EXAMPLE

Horn Antenna

A pyramidal horn in the waveguide-antenna workspace. Explore the original model, recorded electromagnetic fields, radiation patterns and frequency response.

01 · MODEL SETUP

Inside the application.

**Pyramidal horn workspace**The supplied Antenna FDTD Studio modeling workspace, showing the pyramidal horn and Waveguide TE10 port.

**Original horn model**The exported model view, with the supplied dimensions, axes and domain outline intact.

02 · RECORDED FIELDS

Follow the field through the horn.

Recorded electromagnetic-field animation · all 17 exported frames, in their original order and at the original 12 fps playback rate.

03 · RADIATION PATTERNS

See the radiated response.

**3D radiation pattern**The supplied 3D radiation view around the horn, retaining the original color scale.

**Radiation cuts**Pattern versus theta, alongside the φ = 0° / 180° and φ = 90° / 270° polar cuts. The supplied polar plots retain their −20 to 20 dBi radial scales.

04 · PORT RESPONSE

Return loss and matching.

**Frequency response · 8–12 GHz**The supplied magnitude, return-loss, VSWR and impedance plots, together with the port 1 Smith chart. Original axes, curves and labels are preserved.

Images retain the supplied plots, axes and color scales. The video is a web-playback copy of the exported animation, preserving its frame count, dimensions and timing. These are recorded simulation results; this page does not run a solver.
