Products / Resona Antenna

Resona Antenna is the antenna-design and simulation application in the Resona Tools family. It helps radio amateurs, antenna experimenters and engineers build an inspectable model from familiar antenna concepts instead of calculating every wire endpoint by hand.

Questions it helps answer

  • How can I turn an antenna idea into a precise, editable model?
  • How do dimensions, feed points, loads, materials and ground relate?
  • What impedance and SWR does the numerical model predict across frequency?
  • How can I compare revisions before building or modifying an antenna?

Antenna-oriented modeling

Create Straight Wire, Vertical, Dipole, Radial System, Loop, Loop Array and Yagi components. Feed points, RLC loads, electrical junctions, conductor materials, ground and simulation settings remain explicit parts of the design.

Semantic components stay recognizable in the Object Tree and Properties panel. Generated conductors and calculation segments remain derived and inspectable rather than becoming the design you must maintain.

Precise and visual workflows

The Object Tree, Properties, Parameters and 3D viewport stay synchronized. Use exact numeric editing alongside snapping, dragging, measurement and antenna templates. Undo and Redo cover persistent design changes.

Calculation and results

Run a single-frequency calculation or an asynchronous frequency sweep. Results include feed resistance, signed reactance, complex impedance, magnitude, SWR, charts, exact tables and supported exports.

A selected Feed result can be opened explicitly in Resona Line for transmission-line analysis without changing the antenna project.

Projects, offline work and privacy

Save editable antenna projects locally and return to them later. Core design, editing, project files and calculation do not require an account, cloud storage, telemetry or a network connection.

Important limits

Resona Antenna is an antenna-oriented engineering tool, not generic mechanical CAD. Its numerical output is a model prediction, not a guarantee of physical tuning, gain, efficiency, range, structural safety or RF safety. Confirm important designs with appropriate measurements and sound engineering practice.
