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 & native project

The previous compact design is retained for comparison and download. Its separate geometry and RF do not validate the current full-leg candidate.
