Welcome to MatchLab. An antenna reflects part of the power sent to it. MatchLab finds the best matching circuit – a few real inductors and capacitors – so more power is radiated in the bands you need. How it works: 1) load your antenna file, 2) say which frequency bands matter, 3) run the search, then review ranked circuits, tune the parts, check tolerance and export to CST. New here? Press Load a demo antenna below, or open the User manual.
1Antenna data
Touchstone file (.s1p … .s32p)
Choose a Touchstone file (S-parameters of your antenna).
1Antenna efficiency optional
Radiation efficiency of your antenna (CST or similar table, one file per port or a summary table), or far-field radiation patterns (.ffd / .rpf with a summary .xml). Without it, results assume a lossless antenna.
Step 2 – Targets. Tell MatchLab where the antenna must work. Each band has a start and stop frequency, a goal (pass = radiate well, stop = stay quiet) and a weight (importance). Optional Eff ≥ / S11 ≤ targets turn each result green or red. Use the preset chips, the Add several bands library or type ranges like
824-894, 1710-1880.2Target bands and goals
Add one band or several. Each band can have its own goal, weight and pass/fail targets. Tick the bands you want below, then press Add selected bands:
Pass / fail targets
Band sets are kept in this browser only.
Step 3 – Search. Choose how many matching parts are allowed (start with 2–3: more parts match more but lose more), how thorough the search is and which parts library to draw from. Then press Run search – a progress bar shows how far it is. Results open automatically and a search is only counted when it completes.
