Sonnet computes and displays the far-field radiation of planar radiating structures (such as patch antennas).

With Sonnet, you can examine single-layer and multi-layer planar antennas. In addition, you can consider multi-feed systems, with full control on port loads and excitations (magnitude/phase).

Output displays:

• Cartesian plots
• Polar plots
• 3D wire-frame surface plots

Polarizations:

• Linear (theta/phi)
• Circular (RHP/LHP)
• Ludwig's Third Definition (user-selectable reference angle)

Below are some sample plots of a microstrip patch antenna array created using Sonnet:
