ANIMATING E-FIELD ON PLANNER DIPOLE USING HFSS

6-Steps:

Let’s start with a simple Planner Dipole Antenna Design using HFSS. Designing a planner dipole antenna is the easiest design for beginners.

Step 1:

Draw a rectangle as shown below according to your design and resonant frequency specifications (obviously lambda/2).

Step 2: Assigning lumped port

Select the middle rectangle and assign a lumped port of say 50 ohms. The figure below will help you;

Step 3: Create Air Box

Create an Air box with dimensions on every side not less than a quarter wavelength of the structure, See figure below

Figure below

Step 4: Assign Radiation Boundary

Assigning Radiation boundary for your antenna means that the E-Filed lines are directed outwardly from that boundary. So select the Air Box and by right clicking you can see the option of assign boundary, further assign the radiation boundary.

Step 5: Validating and Analyzing

Now its time to validate and analyze; follow the steps: HFSS>Validation Check to validate the design. Once the validation is done, then follow the step HFSS>Analyze All to analyze your design.

Step 6: Results

For S11: HFSS>Results>Create Modal Solution Data report>Rectangular Plot

For Radiation Pattern: HFSS>Results>Create Far Field Report>Radiation Pattern

My result seems like this:

The famous doughnut pattern.

In order to animate the E-Fileds on the dipole structure:

HFSS>Fields>E>MagE……it should look like this:

HFSS>Fields>E>MagE……it should look like this:

To animate the field, the figure below will help you:
