Pyramidal Horn Antenna

Robert Koslover, SARA, Inc.

We provide a convenient 3D RF model of a generic pyramidal microwave horn, with a simple user-adjustable (parameterized) geometry. The model was prepared with Comsol Multiphysics v4.2a with the RF module. The user may specify the input waveguide size (width and height), horn flare length, horn aperture dimensions, and some other useful settings, all as global definitions. Computational region, meshes, and frequency range are then defined automatically (but can also be modified by the user). Two symmetry planes are employed to speed up the computation. The model computes the gain, VSWR, and E-plane and H-plane far-field beam patterns.
