How to Use HFSS Antenna Design Kit to Simulate Common Antenna Types
HFSS Antenna Design Kit (ADK) is a software tool that helps antenna designers to create and analyze various antenna models using HFSS, a powerful electromagnetic simulation software. HFSS ADK can automate the geometry creation, solution setup, and post-processing reports for over 50 antenna elements, such as dipole, patch, horn, spiral, slot, log-periodic, inverted-F, bowtie, and biconical antennas. HFSS ADK can also assist new users in learning to use HFSS for antenna design.
In this article, we will show you how to install and use HFSS ADK to simulate a rectangular patch antenna. You will need HFSS version 14 or higher and HFSS ADK version 2.1 or higher installed on your computer.
Step 1: Download and Install HFSS ADK
You can download HFSS ADK from this link [^2^]. After downloading the zip file, extract it to a folder of your choice. Then run the setup.exe file and follow the instructions to install HFSS ADK on your computer. You may need to restart your computer after the installation.
Step 2: Launch HFSS ADK
You can launch HFSS ADK from the Windows Start menu or from the HFSS user interface. If you launch it from the HFSS user interface, you will see a new toolbar with an icon of a green antenna. Click on that icon to open HFSS ADK.
Step 3: Select an Antenna Type
HFSS ADK will show you a list of available antenna types on the left panel. You can scroll down to find the antenna type you want to simulate. For this example, we will choose Rectangular Patch Antenna under Planar Antennas.
Step 4: Enter Antenna Parameters
After selecting an antenna type, you will see a window with several tabs on the right panel. The first tab is Geometry Parameters, where you can enter the dimensions and properties of your antenna. For this example, we will use the following values:
Length: 30 mm
Width: 40 mm
Height: 1.6 mm
Substrate Relative Permittivity: 4.4
Substrate Loss Tangent: 0.02
Fed Edge: Left
Fed Position: Center
Fed Gap: 0.5 mm
Fed Width: 3 mm
Fed Length: 10 mm
Fed Impedance: 50 ohm
You can also change the units and the coordinate system if you want.
Step 5: Create Antenna Model
After entering the antenna parameters, click on the Create Model button at the bottom of the window. HFSS ADK will generate the antenna model and open it in HFSS. You can view and modify the model in HFSS if you need to.
Step 6: Analyze Antenna Performance
The next tab in HFSS ADK is Solution Setup, where you can specify the frequency range and the solution type for your simulation. For this example, we will use a discrete sweep from 1 GHz to 3 GHz with a step size of 0.1 GHz and a driven modal solution type.
The last tab in HFSS ADK is Post Processing, where you can select the output parameters and plots that you want to generate for your simulation. For this example, we will select Input Impedance (Zin), Return Loss (S11), VSWR (VSWR), Radiation Pattern (3D), Gain (Total), Directivity (Total), Efficiency (Total), Axial Ratio (AR), Polarization (Pol), and Beamwidth (BW). 061ffe29dd
