Fractal Antenna — Link Budget & Designer

Enter antenna & link parameters, simulate a simple fractal antenna design, view a polar lobe, and print results.

Link & Antenna Inputs

Quick Design Outputs

Notes: This tool uses simplified fractal-size heuristics and an approximate polar pattern for visualization. For production RF design use an EM simulator (CST, HFSS) or professional tools.
