STK Tutorials

STK Level 1

This training covers the basics of STK that can be completed with an Evaluation license. The Level 1 - Beginner training is a series of tutorials designed to get you started using STK.

Once you have completed these tutorials, you will be ready to take the free Level 1 STK Certification test!

Intro to Ansys HFSS

In this course, we will demonstrate the analysis of different types of waveguides — a simple waveguide, a stacked waveguide, twist and bent waveguides — using the WR-15 standard waveguide as an example.

Before you get started with the "Intro to Ansys HFSS" course, you may want to watch why an electromagnetic simulation is important to visualize the electric and magnetic fields and how electromagnetic simulation helps to understand the characteristics of electronics and wireless devices and systems.

Ansys HFSS Port Types

Ports are the interfaces of the system through which electromagnetic fields propagate into or away from the system. These ports can be used either as sources or as sinks depending on your requirements. Ansys HFSS in Ansys Electronics Desktop (AEDT) has various options to generate incident fields that interact with a structure to produce the total fields on the computational need. Some of these excitations offered by Ansys HFSS are wave port, lumped port, and Floquet port. This course explains these port types briefly and serves as a guide for selecting the appropriate port type for your needs.

Design of the Half-wave Dipole

Antennas are the front end for every wireless communication device. They have many characteristics like gain, bandwidth, directivity, efficiency, and more. Each of these characteristics are dependent on the application. One basic antenna type is the half-wave dipole antenna. It is simple to design and fabricate with an omnidirectional (rotationally symmetric) radiation pattern and linear polarization. In this course the current structure and theoretical radiation pattern of the half wave dipole antenna is reviewed. The effect of fringing fields along with the current distribution is also discussed. This course was created for Ansys Innovation Courses by Dr. Kathryn Leigh Smith, assistant professor, University of North Carolina-Charlotte, in partnership with Ansys.

Frequency Characteristics of the Half-Wave Dipole

The half-wave dipole is a “narrowband” antenna, meaning that its properties and behavior vary rapidly with frequency.  This means that the characteristics discussed in the previous module are not generalizable across any significant bandwidth.  In this module we will expand our discussion of the dipole antenna to include frequencies where its length is no longer equal to a half wavelength. Specifically, this module will consider how two major properties of the dipole – input impedance and radiation pattern – vary with respect to changes in the driving frequency.

Simulation of a Dipole Array in Ansys HFSS

This course demonstrates the procedure for setting up and analyzing a finite dipole array using the finite array domain decomposition method in Ansys HFSS . This course was created for Ansys Innovation Courses by Dr. Kathryn Leigh Smith, assistant professor, University of North Carolina-Charlotte, in partnership with Ansys.
