Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| openems_create_patchB | Design a rectangular microstrip patch antenna. Calculates dimensions using transmission line model for specified frequency and substrate. |
| openems_create_dipoleB | Design a half-wave dipole antenna. Classic resonant antenna with well-known characteristics. |
| openems_create_monopoleB | Design a quarter-wave monopole antenna over a ground plane. |
| openems_create_hornA | Design a pyramidal horn antenna for specified gain. Calculates aperture dimensions and length. |
| openems_create_helixB | Design an axial-mode helical antenna for circular polarization. |
| openems_generate_scriptB | Generate a complete OpenEMS Python simulation script for a design. The script can be run independently. |
| openems_list_designsA | List all antenna designs created in this session. |
| openems_get_designB | Get full details of a specific antenna design including dimensions and geometry. |
| openems_list_antenna_typesA | List available antenna types with descriptions, typical gain, and applications. |
| openems_check_installationA | Check if OpenEMS is installed and available for running simulations. |
| openems_export_designA | Export antenna design for visualization. Formats: json (full data), svg (vector graphic), ascii (terminal art). |
| openems_optimize_hintsA | Get optimization suggestions for an antenna design including parameter sensitivities and improvement strategies. |
| openems_compare_designsA | Compare multiple antenna designs side-by-side with metrics and recommendations. |
| openems_create_microstripA | Design a microstrip trace and calculate characteristic impedance using Hammerstad formula. Generates 2-port geometry for S-parameter extraction. |
| openems_create_coupled_linesA | Design edge-coupled microstrip lines. Calculates even/odd mode impedances, differential/common-mode impedances, and coupling coefficient. 4-port geometry for NEXT/FEXT analysis. |
| openems_create_viaA | Design a via transition between two PCB layers. Models via barrel, pads, and feed traces. Estimates parasitic inductance and capacitance. 2-port geometry for reflection/transmission analysis. |

Scored across 16 tools
Each antenna and PCB creation tool targets a distinct geometry (patch, dipole, monopole, horn, helix, microstrip, coupled lines, via). Minor potential confusion exists between patch antenna and microstrip line, and between script generation and design export, but overall purposes are clear.
All tools share the 'openems_' prefix and follow a consistent verb_noun pattern (create_, list_, get_, generate_, export_, check_, optimize_, compare_). Naming is uniform and predictable, with no mixed conventions.
With 16 tools, the server is slightly above the ideal 3-15 range but still well-scoped. It covers antenna design, PCB analysis, design management, and utility functions without feeling bloated or redundant.
The set covers design creation, listing, retrieval, export, optimization hints, and comparison. However, there are no update/delete tools for designs, and simulation execution (running OpenEMS) is not directly supported—only script generation is provided. These gaps prevent a full end-to-end workflow.
