Overview of High Frequency Structure Simulator (HFSS)

HFSS Designs and Electric Field Plots

High Frequency Structure Simulator (HFSS) is a 3D electromagnetic (EM) simulation tool used to design a broad range of high frequency products such as antennas, filters, and IC packages. HFSS has advanced 3D electromagnetic field solvers based on finite elements and other integral equation methods supported by high performance computing technology that enable engineers to perform rapid and accurate design of high-frequency and high speed electronic components.

The following figure contains results showing electric field plots on some sample designs created and solved in HFSS. These designs include:

• coaxial resonator model using Eigenmode solver
• driven terminal design of a complex package
• driven modal design of a coax-fed helical antenna with a dielectric support on a finite ground plane
• a waveguide combiner used to combine output power of two 20 GHz solid state power amplifiers
