Field notes
The designer keeps dimensions as expressions over named parameters, while the results area records runs with markers for resonance and −10 dB bandwidth. The page also shows a four-element array workflow: each element has its own port, and steering combines embedded element patterns from four openEMS runs, including coupling effects.
