- Archimedean Spiral Antenna Calculator
- This free online archimedean spiral antenna calculator uses a wire grid method of moments formulation to model a single or multiple arm spiral. The electric current is computed and used to construct the far zone radiation power pattern. The input impedance and directivity are also computed. Requires Silverlight installed.

- Petlowany Antennas by K6NO
- WorldRadio Article on Petlowany antennas base on this principle: if a length of wire is wound into a spiral-shaped coil and excited by a radio frequency current connected to the innermost portion of the coil, it will then, and only then, exhibit RF characteristics that closely approximate those of a resonant linear wire of the same length
