Antenna, RF & radar: how Ansys helps

Antennas and phased arrays live or die on electromagnetic performance you can't see with your eyes. Full-wave simulation is how you design gain, beam-steering, and interference behavior before metal is cut.

The Ansys tools that model it

HFSS — Gold-standard full-wave 3D electromagnetic solver for antennas, phased arrays, radomes, and RF components.
EMIT — Predicts radio-frequency interference and co-site effects when many emitters and receivers share one platform.
STK — Evaluates RF links, radar coverage, and sensor performance in a real mission and orbital context.
