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.

I am currently working on a modeling of a bow-tie antenna for gpr application. Although I am new to Comsol but i have tried to build the geometry. presently i am stuck on the transmission line (coaxial cable) modeling to transmit the electromagnetic field to the conductors. after computing i receive an error message "Uniform lumped port should be placed between two conductive boundaries.
- Feature: Type: Lumped Port
Tag: lport1
Operation: LumpedPort (lport1)"
Please am requesting from you with idea in other to resolve this problem.

Hi HyungKoo Yoon,

did you solve your issue yet??

I'm trying to understand the components of this model. Is there any documentation that I can read?

Thank you!
