Introduction

This document is intended as supplementary learning material for HFSS. It is suitable for beginners through advanced users. This guide includes instructions to set up a transient analysis, solve, and evaluate the results of a double-ridged broadband horn antenna. We assume you already have some experience using HFSS in the frequency domain.

Sample Project: Broadband Ridged Horn Antenna

A broadband antenna, such as the one in this project, can be used to transmit short-duration pulses. Application examples include ground-penetrating radar (GPR) systems for the detection of buried pipes or land mines. HFSS Transient is the tool of choice to simulate the interaction, in the time domain, of a short-duration electromagnetic signal between the antenna and buried objects.

For this problem, perform an HFSS Transient analysis to obtain the broadband S-parameters, E-fields overlay, and radiated fields of the ridged horn antenna.

You will open a partially completed model containing the antenna geometry, complete the model, and set up a Transient Network Analysis. You will then run the simulation and evaluate the previously mentioned S-parameter and field results.
