Think of it as a "smart template engine." You select an antenna type, input your design parameters (frequency, dielectric constant, substrate height, etc.), and the toolkit automatically:
The toolkit places an air box around the antenna. Ensure this box is at least lambda/4 away from the radiating elements. If the box is too close, reflections will corrupt your far-field pattern. hfss antenna toolkit
| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | Feed impedance mismatch | Parametric sweep the feed position or patch width. | | Asymmetric Pattern | Air box or mesh is asymmetrical | Ensure the radiation box is centered on the antenna origin. | | Array Grating Lobes | Element spacing > 1 lambda | Reduce spacing to 0.5 - 0.7 lambda. | | Slow Simulation | Default mesh is too dense | Increase the maximum element length in mesh settings. | | Port not solving | Waveport size too small | Increase the port width to 5x trace width. | Think of it as a "smart template engine
