Simulate & optimiseKeep designing above. Connect a runtime to run a native simulation.

Search settings explained

Physical changes rebuild native operators. Matching and coax changes reuse compatible operators. A radiator window of 0 searches the whole board; smaller values limit the region. Restarts let a finished descent explore another starting point. Target, window and budget do not change the physical model.

Computed antenna

Your copper design

Build & design to compute an antenna

Your input geometry is ready. No computation is running for this definition.

Ground and each driven radiator must be separately edge-connected. Floating copper and corner-only contacts are rejected before RF evaluation. A feed gap between ground and radiator is intentional.

Actual worker counts and elapsed time. Native construction and final CPU verification are separate from candidate search. Every displayed revision binds copper, S parameters and radiation samples together.

Saved HFSS reference

The historical HFSS reference is not included in this public deployment. The live 2.4 GHz demo displays verified results from your connected runtime.
