Antenna Calculator

Nine-step antenna calculator that turns RF specs into CST-ready geometry.

A working instrument, not a brochure. The CST Antenna Calculator walks a user through nine discrete stages — type selection, requirements, coordinates, simulation, results, fixes, versioning, library, and reporting — with real engineering math surfacing as soon as the first form is filled. The Yagi-Uda preset yields actual element lengths, spacings, and feed gaps in milliseconds, and the calculator covers eight antenna topologies plus a custom path. RF engineers, ham radio builders, and antenna researchers get a tool that saves hours of hand-calculation and translates intent directly into simulation-ready coordinates.
