Overview
Antenna simulation covers the design, tuning, and validation of antenna elements and arrays — computing radiation patterns, gain, impedance matching, polarisation, and efficiency across operating frequency bands for automotive, aerospace, and consumer electronics applications. Accurate antenna modelling requires solving Maxwell's equations in the full installed environment, including vehicle body, composite radome, and adjacent electronics — ensuring the real-world gain pattern and coupling effects are captured before physical prototyping begins.

Key Aspects
Solving Maxwell's equations using FEM or FDTD methods to accurately model the radiation and near-field behaviour of antenna structures at any frequency band.
Optimising feed network and matching circuits to achieve target return loss and bandwidth — extracting S-parameters for direct comparison with VNA measurements.
Simulating the antenna in its installed environment — including vehicle body, composite radome, or complex housing — to predict the real-world gain pattern and coupling.
Designing and optimising phased array antenna layouts, element spacing, and excitation weights to achieve target beam shape, sidelobe level, and beam steering range.
