RadPat4W 4.4

RadPat4W is a lightweight Windows application for visualizing and analyzing antenna radiation patterns. Aimed at students, hobbyists, and RF engineers, it helps you inspect how an antenna radiates in space, quantify performance, and document results for reports or design iterations.

Key capabilities include:

• 2D polar plots for azimuth and elevation cuts, with optional 3D views of the far-field pattern
• Linear and dB scales, normalization, and clear readouts at the cursor
• Automatic metrics such as gain/directivity (relative), half‑power beamwidth, front‑to‑back ratio, and sidelobe levels
• Overlay and compare multiple traces or frequencies on the same plot
• Import numeric pattern data from common simulation or measurement outputs, paste from spreadsheets, or enter values manually
• Export publication-ready graphics and underlying data for documentation or further analysis
• Runs on standard Windows PCs and is portable with a minimal footprint

Typical uses range from antenna coursework and ham radio experimentation to quick design checks in professional workflows. If you share a download link or specific version, I can tailor the description to the exact feature set.

RadPat4W is developed by Antennas Research Group. The most popular version of this product among our users is 4.4. The name of the program executable file is radpat.exe.
