About
This tool allows you to change a phased array's geometry, element spacing, steering position, add sidelobe tapering, and other features.
This demo was created by Jason Durbin, a free-lancing phased array engineer.
Usage and Notes
- Antenna elements are assumed to be isotropic. However, the directivity calculation assumes half-hemisphere radiation (e.g. no back lobes). Therefore, the computed directivity will be 3 dBi higher than using pure isotropic. Said in different terms, the individual element gain is +3.0 dBi.
- The mesh can be made finer by increasing theta/phi, u/v, or az/el points. However, increasing the number of points may result in laggy performance.
- Clicking (or long pressing) elements in the phase/attenuation plots allows you to manually set phase/attenuation. Be sure to select "enable override." Additionally, the attenuation pop-up allows you to disable elements.
- Hovering (or touching) the 2-D farfield plot or geometry plots will show the value of the plot under the cursor.

Tracking and Proprietary Information
I use a self-hosted version of Matomo to track viewers and analytics. I do not sell any information and I only use the information for my personal understanding of usage to better improve the tool.
Please note: because the settings are saved in the URL, I can personally view and replicate any configuration. If you or your company deem any configuration to be proprietary, I do not recommend sharing the link. However, I have intentionally not included things like frequency to avoid this concern.
